Why can Weatherford deliver more real time data at the wellsite than any other mudlogging company?

Tim has cabin fever.

EXCELLENCE FROM THE GROUND UP

TM

Our Global Operations Manager for Surface Logging Systems, Tim, is all smiles these days. That’s because he and his team recently designed a new state-of-the-art mudlogging cabin. The spacious interior makes room for more laboratory services at the wellsite. Now exploration companies have access to more data in real time, so they can make better decisions faster. Combined with Weatherford’s patented GC-TRACER™, IsoTube® AutoLoader™ and other Isotech technologies, it’s one more way Weatherford Mudlogging is committed to Excellence from the Ground Up.

3D SEISMIC SYMPOSIUM RESCHEDULED We have been forced to reschedule the 3D Seismic Symposium with new date and venue as follows:

We are very excited to be working with the Colorado Convention Center on the 20th Anniversary of the 3D Seismic Symposium and hope that the changes in date and location will still enable you to join us. The RMAG, DGS and the 3D Seismic Symposium Committee recognize the difficulty this may create in rescheduling and we are deeply sorry for any inconvenience may cause you. If you are unable to attend as a result of these unfortunate circumstances please provide notice no later January 27th to staff@rmag.org.

We look forward to your participation and a very successful symposium, particularly the 20th Anniversary!

Registration Check In and General Session: February 13 Location: Colorado Convention Center, 700 14th St, Denver, CO 80202 This very unfortunate disruption was caused by over-booking of space by the Sheraton Denver Downtown Hotel and their inability to provide alternative space. We were unequivocally informed of this breach of our fully executed contract with the Sheraton on January 13, 2014, we immediately proceeded to find reasonably suitable space and amenities for our symposium as near as possible to the previously scheduled date and location.

President's Column Continued from page 6

OUTCROP

RMAG has been open with our distress about this, given the partnership we have long shared with AAPG. They responded by expressing concern about the financial impact of URTEC on RMAG and the regional societies. AAPG offered to try to develop and support additional ways to work with us, one of which is a Geosciences Technology Workshop (GTW) for 2014. This won’t begin to make up the financial shortfall, however, which underscores a huge, ongoing challenge for RMAG and RMS. The GTW will provide an in-depth, multidisciplinary look at the Bakken-

Three Forks plays on November 1719 at the Colorado School of Mines.

RMAG and AAPG are working together closely on this.

The Rockbusters Ball will also be held in November, time/place TBD. The 2013 Ball at the Oxford Hotel sold out, so watch this space for details.

NAPE Rockies will be back in Denver December 10-12. While this is not an RMAG event, of course, we’ll plan to have a kickoff cocktail party again. Last year’s was big fun, and you don’t have to be registered for NAPE to attend.

Let’s support RMAG by attending these great events. See you there!

missed event and a consistently important payday for RMAG. Focused on “Cracking the Source,” RMS comes back to Denver on July 20 to 22 at the Colorado Convention Center. The dates were moved up last year from our traditional slot in September, and therein lies a story.

R M AG c a n c e l l e d i t s 2 013 Fall Symposium (and suffered a considerable income loss) because of URTEC, a co-production of SPE, AAPG, and SEG that opened last August in Denver. Then URTEC shocked the 2014 RMS meeting organizers and RMAG Board by scheduling their 2014 meeting three weeks before the RMS event, in the same city and with a similar focus, even though our Section meeting had been on the calendar for four years.

The only options open to RMS and RMAG, acting as the paid Manager of the meeting, were: absorption by URTEC (with loss of both income and control), cancellation or rescheduling.

Changing cities was impossible for us, and they declined to do so.

It’s great to have a choice of meetings, of course, and some of our members are the heart of URTEC’s leadership, but unlike many other AAPG events, the local societies have been shut out. Having URTEC in Denver one month after RMS will probably hurt both us and them financially. AAPG is assisting with promoting the RMS meeting to alleviate some of the loss, and both groups are eagerly looking forward to the AAPG Annual Meeting to be held in Denver from May 31 to June 3, 2015.

“20/20 3D Vision:” 3D Seismic Symposium Set for February 13th, 2014

By Steve Jensen, sajensen11@gmail.com Preview: 20th Annual 3D Seismic Symposium Friday, February 13th, 2014 Colorado Convention Center Denver, Colorado The 20 th Annual 3D Seismic Symposium, jointly sponsored by the Rocky Mountain Association of Geologists and the Denver Geophysical Society, will be held Friday, February 13th, 2014 at the Colorado Convention Center in Denver, Colorado. This is the same venue as last year, with its expanded social and exhibitor space. This year’s symposium is co-chaired by Jim Thorson and Mary Sue Purcell.

This is the 20th anniversary of the 3D Seismic Symposium. We are happy that the Geology/Geophysics community in Denver and the Rockies has supported us all these years.

Randy Ray, the long-time past CoChair for the 3D Seismic Symposium will give us a short presentation on looking back at 20 years of the 3D Seismic Symposium.

The 3D Symposium will highlight 12 presentations, concentrating on case histories in resource plays using large-scale 3D seismic surveys.

Case studies include Rocky Mountain projects in the Niobrara, Bakken, and San Juan Basin, along with other analog plays from the US (Marcellus and Eagle Ford), and several from Western Canadian Basins. Attendees to this year’s Symposium will witness the most up-to-date concepts and workflows in our industry, with many of the talks being presented here in public for the first time. Early Registration is currently available by contacting either DGS or RMAG societies or via the 3D Symposium Vol. 63, No. 2

website www.3dseismicsymposium. com.

This year’s Keynote speaker will be Daniel E. Kelly, VP - DJ Basin for Noble Energy. Mr. Kelly will provide an overview of Noble’s significant operations in the DJ Basin and provide examples of the positive impact of 3D seismic on the success of this key Colorado operator.

The first presentation of the day will be our Kickoff speaker, Craig Walters, Director – Wattenberg for Anadarko Petroleum. Mr. Walters will share insights into the success of Anadarko’s robust DJ program, illustrate the benefits of 3D seismic, and highlight the importance of being a good community member

in acquiring seismic in congested areas.

Steve Natali, Senior Vice President - Exploration for WPX Energy in Denver will give a talk titled “Gallup Sandstone Oil Discovery.” This story involves a multi-disciplined team prospecting for horizontal gas in the San Juan Basin until the price of natural gas dropped.

The team quickly switched gears after a significant horizontal oil discovery in a different formation and a different area was found. Four pilot wells plus horizontal were drilled and studied extensively. All four are productive and WPX is engaged in the next phase of commercialization.

LEAD STORY

Labrador’s Drowned Delta, Its Great Lost River, and the Origin of Grand Canyon

By James W. Sears, Department of Geosciences, University of Montana, Missoula MT A gigantic delta lies beheaded in the icy depths of the northern Labrador Sea. With sediment more than 8 km thick, the delta comprises the largest Cenozoic depositional center on the Atlantic margin between Florida and Baffin Island, according to the Canadian Geological Survey (Fig. 1). Before it was destroyed by Pleistocene continental glaciation, its drainage was a close match to the Amazon basin. Its tributaries drained the Rocky Mountains, gathered in what is now Hudson Bay, and flowed to sea through what is now Hudson Strait (Fig. 2). The 3800-km long Northwest Atlantic Mid-Ocean Channel, one of the longest submarine turbidity channels in the world, starts at toe of the delta and curves around Newfoundland to the Sohm Abyssal Plain off the Maritime coast. The great paleo-drainage was named the ‘Bell River,’ in honor of its Victorianera discoverer, Robert Bell of the Canadian Geological Survey.

Exploration companies drilled a number of wells in the delta in the 1970s. From delta samples, V.E. Williams of the University of British Columbia identified fossil spores that had been recycled from Mesozoic and Paleozoic strata of the western interior. Some of the recyclant spores may have originated in the southern Colorado Plateau, where recent age-dating

shows that deep erosion was taking place while the delta beds were being deposited. Williams identified the recyclants Calamospora, Convolutispora, Densoisporites, Foveotriletes, Matonisporites, and Osmundacidites wellmanii, which the USGS also had identified in the Chinle Formation of Petrified Forest, and a LycosporaTriquitrites-Punctatisporites assemblage, which the USGS had also reported from the Supai Group of Grand Canyon.

“20/20 3D Vision:” 3D Seismic Symposium Continued from page 12

‘Combined Microseismic and 4D to Calibrate and Confirm Surface 3D Azimuthal AVO/LMR Predictions of Completions and Performance and Well Production in the Horn River Gas Shales of North East British Columbia.” To assist in the optimizing stimulation efforts, seismic data and microseismic are used to estimate and map four parameters that influence hydraulic fracture effectiveness: rock properties, in-situ stress, natural fractures and reservoir geometry.

Bob Hardage, a professor at the University of Texas at Austin will speak about “Evaluating Unconventional Reservoirs with Low-Cost Multicomponent Seismic Data.” The Exploration Geophysics Laboratory at UT of A has developed a new S-wave technology that should overcome much of the reluctance to utilize S-wave data in unconventional resource plays. This technology is based on the use of direct-S modes produced by verticalforce sources.

Jack Wiener with Halliburton Energy Services will present “The Greeley 3D Seismic Survey: One of the Nation’s Largest Urban Surveys Leads to Niobrara Horizontal Activity.” An oil and gas producer based in Greeley, Colorado put together a plan to acquire subsurface knowledge in the urban area. Halliburton interpreted the data and provided detailed structural analysis and framework modeling of the Niobrara and Codell formations.

Angie Southcott with WPX Energy in Denver will talk about “3D Seismic Proves its Value in Bakken Geosteering.” Improved geosteering has been a key driver achieving lower well costs in the Williston Basin.

The improvements are in part attributable by using advanced 3D seismic data processing. Using 3D seismic for geosteering requires: 1) resolving the Bakken interval, 2) accurately converting seismic surfaces to depth.

Tim Berge with Pangean Resources will present “3D Imaging of Bakken Reservoir Targets, North Dakota." He applies structural attribute methods to a new spec survey to demonstrate how effective full use of 3D seismic data can aid development drilling for these objectives: 1) imaging of natural fractures, 2) estimate fault heave, 3) show stratigraphic details of the Pronghorn sands, 4) predict channel fill, and 5) better well steering to target.

Claudia Deunas, a graduate student at the Colorado School of Mines Reservoir Characterization Project will

Vol. 63, No. 2

present “Understanding Rock Fabric and Reservoir Quality Index Using Combined Multicomponent Seismic Inversion and Well Log Cluster Analysis.” Using multicomponent seismic data from Pouce Coupe Field, North East British Columbia, she predicts rock fabric of the Monteny Shale. The objective is to understand heterogeneity using multi-attribute analysis of wells integrated with multicomponent seismic.

Tony Rebec with Geokinetics, Inc. in Houston will talk about “Risk Reduction for Prospecting in the Unconventional Niobrara Play.” A methodology is presented to reduce risk in identifying sweet spots within the local structural framework using the full azimuth 3D seismic and well logs for calibration. Based on azimuthal 3D seismic data processed through OVT migration, elliptical and pre-stack simultaneous elastic inversion with well to seismic correlation, areas of high potential interest can be differentiated.

Reinaldo Michelena with iReservoir, Inc in Denver will present “Leveraging Seismic Technology for Unconventional Reservoirs: From Seismic to Flow Simulation.” He will show how seismic data can help in characterization of matrix and fracture information can be used to constrain flow simulation models. His workflow consists of four steps: 1) facies definition, 2) seismic calibration, 3) geologic modeling, and 4) flow simulation. Data examples from the Rockies and offshore South America will be shown.

Ross Peebles with Global Geophysical Services will talk about “Production Focused Seismic for the Development of Unconventional Resources – Insights from the Eagle Ford.” Pre-stack and post-stack attributes are derived from a recent high-resolution full-azimuth long-offset 3D seismic dataset. Structural attributes like curvature and incoherence can highlight faults and factures. Frequency attributes like spectral decomposition can relate porosity, TOC and rock properties. Azimuthal anisotropy can indicate fractures, stress, and overpressure.

Registration is now open through either RMAG or DGS, or via the 3D Symposium website (www.3dseismicsymposium.com). Sign up now and take advantage of the early registration discount.

Lead Story Continued from page 13

Figure 1. Cross-section of drowned delta in Labrador Sea, after Balkwill et al., 1991, DNAG Volume. Stippled layers range in age from Eocene to Pleistocene. Base of stratigraphic section is Early Cretaceous. Sediments onlap basaltic seafloor to east and rifted Labrador continental margin to west.

This essay extends my hypothesis that an early version of the Colorado River may have turned north near present-day Lake Mead and joined a great southern tributary of the Bell River to deliver sediment to the delta.

I suggest that the tributary flowed along a Paleogene rift system through Nevada, Idaho, and Montana. For a detailed discussion and complete references, see my 2013 GSA Today paper.

The Bell River basin took shape in early Paleogene time, after the Western Interior Seaway had withdrawn from Canada. The combined effects of Yellowstone hotspot tectonics, basin-range faulting, and the opening of the Gulf of California destroyed or diverted segments of the proposed paleo-tributary in Neogene time. The following paragraphs take the reader ‘upstream’ from Canada to Grand Canyon, highlighting evidence for the evolution and extinction of the paleovalley.

On the plains of southern Canada, Paleogene and Neogene gravel of the paleovalley escaped Pleistocene glacial erosion on nunatak ridges that stood above the ice sheets. Canadian petroleum geologist Dale Leckie determined that the gravel had filled broad, northeastflowing river channels. The river had carried streamrounded pebbles from distinctive sources in bedrock outcrops of the Montana Rockies, hundreds of kms to the southwest. Other remnants of the paleo-riverbed cap terraces that lead southwest from the Canadian plains to the Montana Rockies.

In the Rockies, Paleogene and Neogene sediments, locally greater than 1.5 km thick, fill deep grabens in a regional rift system. According to new data from Hari Mix and colleagues at Stanford University, the rift system propagated from Montana to southeastern Nevada in Eocene through Oligocene time, in concert with southward-migrating volcanism. The grabens chronicled Paleogene collapse and spreading of the Cordilleran highlands. The grabens reached to within 100 km of the western end of Grand Canyon, and were positioned to channel runoff from the early version of the canyon into the great southern tributary of the Bell River.

In southwest Montana, the grabens contain fluvial sediments that had likely provenance sources in the Great Basin, south of the modern Continental Divide and Snake River Plain. Volcanic mudstones of the Renova Formation correlate with the Oligocene ash sheets of the southern Great Basin, at the south end of the Paleogene rift system. The unconformably overlying Sixmile Creek Formation records northeast-trending paleocurrents in tephra (Fig. 3) and contains exotic pebble lithologies unique to Great Basin bedrock strata (Fig. 4). These include distinctive rocks of the Late Paleozoic Antler orogenic belt that were exposed on the flanks of the rift system in central Nevada.

Dozens of active basin-range faults now segment the old paleovalley in Montana and Idaho. Its river gravels are faulted, folded, and internally deformed (Fig. 5).

The Continental Divide now forms the headwaters of the upper Missouri River - the truncated descendant of the old Bell River tributary.

As the rising mountains beheaded the paleovalley at the Montana/Idaho border, drainage in southern Idaho was diverted into Neogene Lake Idaho.

it turned south to the Gulf of California. Spencer found that genetic similarities of fish in the upper Snake and upper Colorado rivers indicate that the rivers formerly occupied a common basin.

The Paleogene rift system had propagated south from Montana to the latitude of Grand Canyon by 28 million years ago. The east shoulder of the rift mapped

by Mix and others coincided with the west shoulder of a broad, north-trending paleovalley that Ernie Anderson and Susan Beard of the USGS mapped on the edge of the Colorado Plateau, adjacent to Grand Canyon. Recent work by Melissa Lamb of the University of St. Thomas indicates that until basin-range faulting began 17 million years ago, most of the sediment in the paleovalley bypassed the system toward the northeast. Thus, the paleovalley could have transported sediment from the

Grand Canyon northward into the adjacent rift system between 28 and 18 million years ago.

Dickinson showed that the Middle Miocene floor of the Little Colorado River graded to mid-depths of eastern Grand Canyon, consistent with the erosion depth determined by Flowers and her co-workers. That mid-canyon depth is marked by a prominent bedrock terrace about 5 km wide that transects the entire length of Grand Canyon. In eastern Grand Canyon, it presents a bench at the top of the Mississippian Redwall Limestone on a series of buttes, spurs, and ridges (Fig. 6). In central Grand Canyon it spans the Esplanade surface on top of the Supai Group (Fig. 7), and in western Grand Canyon, it occupies the broad surface of the Hualapai Plateau.

The terrace changes stratigraphic level as it transects Laramide folds, consistent with their structural relief.

The surface evolved diachronously, with the western part much older than the eastern, but may have been integrated by Late Oligocene/Early Miocene time. The Hualapai Plateau is locally overlain by Eocene sediments, as well as by 20- to 15-million year old basalts.

The Rio Grande Rift began to propagate north through New Mexico at about 26 million years ago, according to Steven Cather at New Mexico Tech and others. Its uplifted western shoulder linked with the rising Mogollon Rim of central Arizona to enclose the headwaters of the early Colorado River, which threaded its way west to the old Hualapai Plateau, the lowest gap on the southwestern rim of the Colorado Plateau.

The mid-canyon terrace of Grand Canyon is incised by the steep, narrow, 800-m deep Inner Gorge. George Billingsley of the USGS showed that the Inner Gorge was carved after 6 million years ago, because it dissects a basaltic dike swarm of that age. The incision of the Inner Gorge may have been instigated by lowering of erosional base level upon diversion of the Colorado River to the Gulf of California at about 5.3 million years ago.

It is thus possible that the Colorado River eroded Grand Canyon to its mid-depth in Late Oligocene/Early Miocene time, turning north in Nevada to flow down the Paleogene rift system to Montana and the Bell River. The erosional period included the Miocene climatic optimum, when deep erosion also dissected the paleovalley from Nevada to Canada.

By 5.3 million years ago, the Colorado River clearly flowed south to the Gulf of California, as has been documented by numerous workers. But what might have happened to the river between 17 and 6 million years ago?

Basin-Range faulting began at the western edge of Grand Canyon about 17 million years ago. Years of work

by USGS geologists has shown that basin-range grabens next to Grand Canyon filled with locally-derived alluvial fans and playa sediments from 17 to 6 million years ago, with no evidence of a through-going Colorado River.

Richard Young of SUNY suggested that basin-range faulting dammed up the Colorado River at western Grand Canyon about 17 million years ago, creating a playa lake basin. At about the same time, the climate shifted from the extremely wet Miocene climatic optimum to

Vol. 63, No. 2

hyper-arid conditions. According to Steven Cather and co-workers, erosion seems to have stagnated on the Colorado Plateau during that same period.

Karl Karlstrom’s research group at the University of New Mexico found that the headwaters of the Colorado River had barely reached southern Utah before the upper Colorado River basin was finally integrated in Pliocene time. In that case, the Little Colorado River would likely have been the main stem of Grand Canyon’s drainage basin in Late Miocene time. Even in today’s climate, the Little Colorado River is dry for most of the year above Blue Springs. It would have been even more ephemeral in hyper-arid Late Miocene time, before erosion cut down to the Redwall/Muav aquifer to open Blue Springs.

Geologists have spent decades searching the southwest for a route that an early Colorado River could

have taken to the coast from an early Grand Canyon, perhaps the answer lies in an unexpected northern course to the far Labrador Sea. Diversion to the Gulf of California from Labrador would have shortened the distance to sea level by 4500 km, perhaps driving incision of the Inner Gorge through the old Miocene bedrock valley floor.

Several key locations could be studied in more detail to verify the hypothesis. Detrital zircon analysis provides a new tool that could test links between proposed source rocks in Nevada and stream pebbles and sand as far away as northern Montana and southern Canada. New geochemical methods could test matches of muds in the Labrador delta and proposed source rocks in the southern Colorado Plateau. Detailed mapping in southeast Nevada could test the proposed fluvial linkage

RMAG Luncheon Programs – February 5th

Ordovician-sourced Oils from the Williston Basin, USA: Where did they come from and where have they gone?

By John B. Curtis, Colorado School of Mines and John E. Zumberge, GeoMark Research, Ltd., February 5, 2014 Using multivariate statistics, over 350 Williston Basin oils were grouped into families which share common sources based on genetic-specific biomarkers and stable carbon isotope compositions.

Ninety (90) Middle Ordovician-sourced oils were identified by their unique n-paraffin distributions (odd over even carbon number preference around n-C17 and n-C19 and greatly diminished isoprenoids) due to the microorganism G. prisca. These oils are also characterized by relatively high C19 tricyclic terpane and C24 tetracyclic to C23 tricyclic terpane ratios as well as having the most positive (enriched) stable carbon isotope compositions of oils from the Williston Basin.

Most of these oils were produced from the Ordovician Red River Formation, and source rock evaluation of Red River cores and cuttings (e.g., TOC and Rock-EvalTM data) suggests that the Red River is also the principal source rock unit. Estimates of oil thermal maturity based on biomarkers show that the most mature oils exist within the basin depocenter while the least mature oils are located along the Cedar Creek Anticline. Furthermore, another smaller set of oils (<10) contain G. prisca biomarkers (albeit diminished) but have very negative (depleted) stable carbon isotopic compositions; these oils may have been generated from shales of the Ordovician Winnipeg Group.

Finally, a few oils with predominantly Mississippian carbonate biomarkers (i.e., Lodgepole Formation source) appear to have an Ordovician component as revealed by principal component analysis.

These oil data and observations have been integrated with mapped source rock occurrence, quality and thermal maturity to yield new insight into the Ordovician petroleum systems of the US portion of the Williston Basin.

Fluvial megafans in the Uinta Basin, a consequence of extremely bad early Eocene weather?

By Piret Plink-Bjorklund, pplink@mines.edu, Colorado School of Mines

The early Eocene fluvial system exposed along the southern margin of the Uinta basin has received a considerable amount of attention. The peculiar nature of the fluvial succession of the Wasatch and Green River Formations in the Uinta Basin has led to a number of interpretations, including fluvial channels, and deltaic mouth bars. Not surprisingly, as the fluvial succession is dominated by gradational planar laminations, aggradational low-angle convex-up structures, scour-andfill structures and climbing-ripple laminations, common in mouth bars and turbidites. Moreover, architecturally, the channels are, in many places, amalgamated into thick, sharp-based tabular sandstone intervals, and show a stratigraphic large-scale upward increase in sand content. Thus, these fluvial systems are distinctly different from fluvial facies models.

Vol. 63, No. 2

Rivers with distinctly flashy water supply, caused by extreme precipitation, are distinct from perennial rivers in terms of sedimentary structures, barforms and architecture. The figure shows three different types of flashy rivers and how they compare to a perennial system. LFR – lower flow regime; MFR – medium flow regime; UFR- upper flow regime; HDR – high deposition rate. Flashy rivers have a significantly higher proportion of upper flow regime and high deposition rate structures, whereas perennial rivers are dominated by medium flow regime structures and lack high deposition rate structures (a, b, c). Barforms in flashy rivers tend to be simple and thick (c, d). The dominance of the above sedimentary structures indicates upper flow regime deposition and very high deposition rates. The extremely

Fluvial megafans in the Uinta Basin, a consequence of extremely bad early Eocene weather? and channel dimensions, indicate deposition in fluvial megafans. Moreover the channel dimensions indicate a large river system, rather than small rivers draining local uplifts. The fluvial megafan systems are highly aggradational and capture large volumes of sediment.

Thus, the volumes of siliciclastic sediment that reached the Lake Uinta are considerably smaller than the volumes captured in the megafans. The available absolute age dates, biostratigraphy and out stable isotope record show that the Wasatch and Green River Formation fluvial systems along the southern basin margin are of early Eocene age. Moreover, the data links the fluvial megafan progradation and retrogradation episodes to early Eocene global warming events (the PaleoceneEocene Thermal Maximum, and the six successive Early

high deposition rates are also shown by the dominant downstream accretion of bars, and unit bar thickness of more than 10 m in places. At unit bar bounding surfaces trace fossils and pedogenic modification occurs, showing that the channels were dry for sustained periods at times.

High degree of channel amalgamation in the proximal part of the succession indicates high channel avulsion frequency. Further distally and laterally the avulsions are indicated by splay packages. Collectively these features indicate a flashy river system with very high peak discharge, and intermittent sustained droughts. In fact these sediments are more similar to flash flood and megaflood deposits than fluvial facies models developed for perennial systems. The laterally extensive nature of this system across ca 200 km, together with the vertical trends of upward increasing and decreasing sand content

Roving Mars -- An Update on Recent Exploration of the Red Planet

By Ira Pasternack, Comet Ridge Resources, April 2, 2014

The talk will present examples of some of the Martian depositional environments capable of sustaining life including fluvial valley networks and deltaic sediment bodies in lacustrine basins.

Our knowledge of Martian geology has undergone tremendous growth over the last decade due to the highly successful surface rover and orbiter missions that have been surveying and sending data back from the planet since 2004.

Much of these data are readily available for free download from various NASA or affiliated organization websites (i.e., http://nssdc.gsfc.nasa.gov/nmc/). The talk will include some of the author’s favorite downloaded imagery and brief historical review of earlier probes sent to explore Mars, will demonstrate they have not always been so successful.

Since American astronomer Percival Lowell popularized Martian “canals” as indications of intelligent life during the early 20th century, the search for signs of life on Mars continues to be a major focus of exploration. Each of the rover landing sites was specifically selected to optimize the potential for finding evidence of past life. The talk will present examples of some of the Martian depositional environments capable of sustaining life including fluvial valley networks and deltaic sediment bodies in lacustrine basins.

Mars has a much more complete stratigraphic record than the Earth because of the absence of plate tectonics and lack of crustal recycling. Mars is the location of one of the tallest mountain peaks identified in the Solar System, “Olympus Mons”--3 times the height of Mount Everest--as well as the largest known canyon, the 1900-mile-long “Valles Marineris”.

Although the talk is well beyond the normal scope of Rocky Mountain region geology topics presented at RMAG luncheons, there are numerous Colorado connections to the recent Martian missions beyond the similar red color of the rocks. Colorado companies were responsible for the construction of various key components or instruments onboard the rovers and orbiters. There are also Colorado ties to some of the scientists responsible for conducting the Martian research.

Application of Structural Methods to Rocky Mountain Hydrocarbon Exploration and Development

Edited by: Constance N. Knight, Jerome J. Cuzella, Leland D. Cress Co-published by The American Association of Petroleum Geologists The Rocky Mountain Association of Geologists With increasing industry emphasis on developing “unconventional” tight reservoirs and on enhancing recovery from existing fields, geologists are facing new challenges. Identifying fracture characteristics within petroleum systems is essential. Understanding the timing of tectonics and the formation of structures is important, as these factors strongly influence hydrocarbon generation, migration, entrapment, and preservation. The purpose in publishing this collection of key papers is to aid future works in addressing complex interrelationships between structural geology and hydrocarbon exploration and development.

The first four chapters of this book focus on structural concepts and techniques. The second part of this book is a collection of Rocky Mountain fault and fracture studies. These well-documented studies are valuable reference materials for all petroleum geologists.

Authors and Editors Needed: RMAG Oil & Gas Fields of Colorado!

RMAG is working toward the publication of a guidebook dedicated to short field studies of a set of selected oil and gas fields in Colorado.

In large part the format will be similar to earlier publications of this type: a several page article that will include a one page summary with a small set of maps and cross-sections adequate to give the reader a lot of information in a short amount of time.

The RMAG committee working on this publication has selected 85 fields for review. In addition, we expect to have extended discussion around several large â&#x20AC;&#x153;resource playâ&#x20AC;? areas such as the Piceance Basin or the Greater Wattenberg complex including the recent horizontal Niobrara play.

The committee is currently looking for authors to do field studies and to put together material for publication.

Each author may contribute one or multiple field studies. We will also need a group of editors for both technical and copy (grammatical and graphical) review.

Please volunteer! Committee contacts below: Dean DuBois, Committee Chair 720-876-5366 dean.dubois@encana.com James Milne 303-894-2100 x5117 james.milne@state.co.us James Rogers 303-832-2328 jim_rogers1@comcast.net Vol. 63, No. 2

Check it Out! Energy for the 21st Century: Opportunities and Challenges for Liquefied Natural Gas (LNG) Author: Susan L. Sakmar, Visiting Law Professor, University of Houston Law Center LNG is the fastest growing segment of the energy market and its role as the 'glue' linking global gas markets is set to intensify as more and more countries look to LNG to meet growing energy demand with cleaner burning fuels. This timely book provides critical insights into all aspects of the dynamic LNG business, including the LNG value chain, the evolution from regional trade to a more globalized LNG market, LNG pricing, contracts and trade, and emerging issues such as the impact of shale gas on global gas markets and the prospects for U.S. LNG exports.

The author is currently a Visiting Assistant Professor at the University of Houston Law Center where she teaches a seminar on Shale Gas and LNG. Available on Amazon at www.amazon.com/dp/1849804214, $157.48. »
