RMAG April Board of Directors Meeting
By Jacinda Nettik Brown, Secretary (jacinda@caerusoilandgas.com) The Board of Directors meeting was held on April 17th, 2013 at the RMAG office. We began this meeting with guest, John Robinson, requesting permission to borrow RMAG Awards Committee to help with nominations for the 2017 Houston Museum of Natural Science exhibit which will honor 100 geologists for the 100th Anniversary of AAPG. Permission was granted. If you’d like to be part of this committee please contact the RMAG staff. Next, RMAG Treasure Mike Kozimko went over the RMAG balance sheets. He reiterated that cash flow versus budget are important numbers on the balance sheets. It appears our expenses are up slightly to budget. The 2012 audit was completed. Mike Kozimko provided a summary of the findings at April’s board meeting. Its official, RMAG is an endorsing society for NAPE Rockies! As an endorsing society we will use our social and broadcasting media to provide NAPE information to our members. Mark your calendars, NAPE Rockies will be held in Denver December 11-13th this year.
RMAG BOD approved a motion accepting a Field Trip Plan of Action Document, a requirement in order to qualify for insurance coverage for our On the Rocks Field Trips. R M AG B O D a p p rove d a motion allowing the Publications Committee and others to use the new RMAG vector logo, which closely matches original bitmap logo. The new vector logo has already been put to good use when the BODs presented the two expecting board members with baby onesies that included the new RMAG Logo and read, “I want to grow up to be a geologist, just like my mom!” The Industr y Leaders of the Future (ILF) Committee has scheduled their first event for May 14th titled “The Road to Owning Your Own Oil and Gas Company.” If you’d like to hear about future ILF events you can sign up the RMAG website by clicking on the Committees link at the top of the page. ILF Committee was formed for the advancement of young professionals through social, educational and civic oriented events. It is dedicated to providing a forum for networking and career development for professionals in the global energy industry. I hope you all enjoyed the RMAG Spring Symposium this year held on April 23rd. I know I especially enjoyed the Keynote Address by Chris Wright, CEO of Liberty Resources who discussed fracs. He had a couple of key take a ways including, “fracs don’t like each other” and well performance is tied to “how much plumbing you put in it.”

A Great Combination... Golf, Biking & Publications! June 27th is the Annual RMAG Golf Tournament at Fossil Trace golf course in Golden (image modified from www.fossiltrace.com). Velociraptors and the golf course probably weren’t present in the Pierre seaway 70+ million years ago--before the existence of putting greens, but not the roughs or (dinosaur) fairways.

chair. Editors of The Mountain Geologist, Outcrop, and other publications are listed near the journal covers. The publishing process is quite involved; some of this is obvious, such as requesting submittals, technical reviews, copy editing, and final layout of the papers, and encouraging authors and reviewers to follow deadlines. Other issues include understanding and updating copyright requirements, keeping Suggestions to Authors current with our evolving technology (and sometimes science), and researching options for disseminating our science. RMAG has a couple of books and a GIS publication in progress. AAPG Studies in Geology 65, “Application of Structural Methods to Rocky Mountain Hydrocarbon Exploration and Development” is a joint RMAG/AAPG volume that will be available this year. Editors are Connie Knight, Jerry Cuzella, and Leland Cross. The planned “Oil and Gas Fields of Colorado” volume is a play-based update of 85 major oil and gas fields; Dean Dubois (dean.dubois@encana.com) is the main contact, please contribute your expertise to a chapter on a field. The last field studies publications were a number of years ago, and I still use them in my resource assessment research. Also, nine pages from the Rocky Mountain Atlas “Big Red Book” were digitized with the resulting faults and other structures, outcrops, some contours, and igneous intrusions saved in ArcGIS shapefiles and layers; Laura Biewick (lbiewick@usgs.gov) of the USGS is the compilation editor for this planned RMAG GIS publication. The Mountain Geologist and a number of other RMAG publications are also accessible through AAPG Datapages, which provides our research and information
Richard (Dick) Keefer is a new (as of March) assistant editor for The Mountain Geologist. My experience with him as editor for the USGS Central Energy Resources Science Center is that he is a wonderful editor and great fellow who tolerates our ranting while he improves our papers (also known as offspring). The RMAG Publications Committee is a very dynamic group that includes editors, other committee chairs and members, and RMAG staff; they oversee planning and construction of the Outcrop, The Mountain Geologist, and guidebooks and other publications.

How do we ensure that every Weatherford mudlogger performs at the same high standards around the globe?
They all have to get past our man Wayland.
EXCELLENCE FROM THE GROUND UP
TM
Weatherford is passionate about training, and that’s where Wayland comes in. His mudlogging training program begins with hands-on classroom instruction and ends with rigorous tests at the wellsite. We call it Competency-Based Training. You’ll call it another benefit of working with Weatherford. With courses for basic and advanced mudlogging, as well as for specialized services, Wayland’s program helps mitigate hazards and enhance data accuracy. It’s just one more way Weatherford Mudlogging is committed to Excellence from the Ground Up.

to a broad audience. RMAG also receives royalties when publications are purchased from Datapages. We are also investigating partnering with GeoScienceWorld (GSW) as a web-based publication provider. One of the issues with GSW is that our mostly PDF-format books and journals would need to be converted to XML or HTML5 formats (remember when we just needed to know geology terms?) by their outside contractor (not much money, but pinching pennies is good when you have many thousands of pages). On a totally non-associated topic, at home we’ve been battling voles (pronounced evoles) that are building the equivalent of a New York subway system in the front yard. We’ve almost vanquished the enemy, with the help of some garter snakes (all named Fred) and Cooper’s Hawks (we named them Alice and Gary). In the old days we’d probably just poison the voles. Now we use mousetraps laced with organic almond butter with certified gluten-free oats and masa harina corn. I probably should just pack the traps with fat and sugar and see if the voles succumb to type 2 diabetes or heart disease.

LEAD STORY Advanced Mud Gas and Rock-Fluid Analysis Aids Evaluation of North American Unconventional Plays
By Don Hall, Michael Sterner, and Rohit Shukla, Fluid Inclusion Technologies, Inc., fit@fittulsa.com

chromatography (GC), mass spectrometry (MS) or GC coupled with MS, and comprehensive cuttings analysis for trapped fluids and organic and inorganic makeup in the lab is the most promising. As many unconventional resources have a significant number of historical vertical penetrations, rock-fluid databases can be established rapidly and cost-effectively at an early stage without drilling new wells.
as carbon dioxide, helium, hydrogen, atmospherics and sulfur-bearing volatiles. It can discriminate among the major classes of volatile organic compounds (paraffins, naphthenes, aromatics) as well as contributions from the drilling fluid. Evaluation of such a broad range of chemical compounds allows for unsurpassed chemical fingerprinting. Additionally, a number of inorganic/ organic species combinations are indicative of specific subsurface processes. The instrument is uniquely suited for organic-base mud systems, which typically hamper data analysis from other devices, and works in low-pressure reservoirs where conventional gear is ineffective. Within unconventional plays DQMS has been used to distinguish among producible hydrocarbon fluid types, identify lower quality or residual systems, evaluate potential for water production, assess compartmentalization, and recognize fractures and faults. These data have been used to optimize completions for less costly and better producing wells allowing some operators to rethink and minimize logging runs. Monitoring drilling-generated hydrogen can serve as an early warning for bit wear, failing down hole motors and general friction in the drill string. This specific application has tangibly contributed to lower drilling costs, where utilized.
Advanced Mud Gas Analysis: Recent developments in application of membraneGC, GCMS and direct MS analysis to mud gas, along with improvements in mud gas extraction instrumentation and techniques (e.g., constant volume, constant temperature, gas-in and gas-out arrangements) provide data sets that are light years ahead of historical Hot-Wire/GC methods. Of these new techniques, direct quadrupole mass spectrometry (DQMS) is by far the most comprehensive, sensitive and flexible tool for compositional evaluation of formation fluids in near real time. DQMS evaluates C1C10 petroleum species, and inorganic compounds such

Comprehensive Cuttings Elemental-Fluid Analysis: A new procedure for cuttings or core analysis in the lab has been developed during which the rock is first photographed under visible and UV light, then crushed and analyzed for included hydrocarbon and non-hydrocarbon species with a sensitive mass spectrometry system, and finally probed for its elemental composition with a customized XRF analyzer. A key aspect of the process is that all analyses are conducted on the same 1 gm rock sample with an automated system, thus preserving interrelationships among rock type, fluid type and rock chemistry.

Together they provide unique insights into controls on hydrocarbon, reservoir and pay distribution, represent an additional tool for well placement, and allow organized archival of rock type, fluid and rock chemistry information that is easily retrieved and studied in the context of future wells, even in the absence of the original rock material. Of interest is that these analyses can be performed on historical samples of any age, drilled with any mud/bit type.

The purpose of this memoir is to provide a practical reference for geologists, geophysicists, engineers, and students to gain a better understanding of the various state-of-the-art techniques and applications of electron microscopy for shale hydrocarbon reservoir evaluation. This reference volume is intended for both specialists and nonspecialists alike and will serve as a practical guide for petrographic interpretation and reservoir analog studies. This book contains 13 highly illustrated peer-reviewed papers that describe modern techniques and recent case studies, and a catalog of nearly 250 described SEM images of known productive and potential shale hydrocarbon reservoirs in the United States. The included DVD contains a
predicting fluid type, composition, quality and volume in tight rock, as well as identifying variability along laterals that can be exploited for more effective completions. XRF data from 30+ major, minor and trace elements in large cuttings sample sets from vertical and horizontal wells can be used to document lithology and cements, produce chemical stratigraphic profiles in otherwise monotonous sections, establish depositional environments, facies and provenance, and provide some information relevant to rock behavior during completion activities. Type profiles through vertical penetrations can be used to help optimize lateral placement and retrospectively establish borehole trajectory in horizontal wells. Finally, white light and UV images provide grain scale details Continued on page 12 Âť

that can be correlated with other data sets to provide a more integrated understanding of what is controlling hydrocarbon and porosity distribution in the system as well as general formation recognition, evaluation of cuttings quality (and implied drilling conditions), and presence of additives that may affect other analyses. UV images indicate specific mineral or kerogen fluorescence that can be correlated with cement or rock types that are difficult to recognize under white light. Kerogen fluorescence color can be related to maturity. Archived images are much easier to manage than the samples themselves, persist when samples are no longer available and allow geologists to look at the rocks at their desks without relying on sample descriptions or lower quality images from well site.
Helium, C1 Norm and C4 Norm curves (red brackets, “E” intervals, red and orange bars). The most producible portions of the well, based on gas volume and porosity, are indicated where helium is high and separation is recorded between the C1 Norm and C4 Norm curves as a result of natural chromatographic separation of light species in tight rock. In other words, the fractured or otherwise more porous sections of the reservoir concentrate the mobile species, which are weighted toward small molecules like methane and helium. These zones are referred to as “enhanced”, while “depleted” zones occur where light/heavy ratios are low (labeled “D” in Fig. 1). Among other possibilities, depleted zones may indicate that charge has been dissipated via throughgoing fractures. The toe of the wellbore contains higher concentrations of sulfur species which may represent an undesirable component of the produced fluid, known to be present in this particular area (pink bracket). Of equal interest is the distribution of water, which is indicated

by the ratios of benzene to toluene and benzene to hexane (blue brackets and bars). These increase in elevated water saturation intervals, because benzene is more soluble in water than both toluene and hexane. Considering all of these data allows one to evaluate the most prospective portions of the lateral based on gas composition, gas quality, deliverability and potential for water production. These are indicated by the green bars at the bottom of the diagram. Availability of this extensive data set based solely on mud gas represents a dramatic improvement over conventional approaches, and is particularly valuable in horizontal wells where log suites are minimal.
a horizontal wellbore through a light oil/condensate bearing section of the Cardium Sandstone, Alberta. This well encountered an unexpected down-faulted section causing the borehole trajectory to intersect the overlying shale. The borehole was redirected into the underlying sand near the end of the well. These lithologic relationships are identified by the red (sand) and blue (shale) tick marks on the left hand side of the figure, which correlate with discrete zones on a silicon vs. aluminum cross plot. The orange bands represent duplicate sections at the top of the sand, and have substantially similar chemical and volatile response. The red band illustrates dry gas within the shale, possibly related to fracturing in the vicinity of the shale and introduction of more mature gas from deeper in the system. Of particular interest is the correlation of the highest FIS gas and oil response with decreased silicon and increased calcium and iron shown by the green band. Petrographic work on cuttings indicates that this zone is characterized by siderite-enhanced porosity (yellow arrows lower left image), and higher visual light oil/condensate inclusion abundance (blue fluorescing areas, lower right image). The green zone was tested separately and displayed the highest initial rates in the well. Use of this combined rock and fluid approach on vertical wells can be used to more successfully place laterals.
FIS for Early Prediction of Production: A simple example of using cuttings volatile analysis to anticipate and rank eventual production in unconventional reservoirs is shown in Figures 2 and 3. In Figure 2, cuttings methane concentrations (calibrated millivolt responses from the mass spectrometer) from four horizontal wells within a geographically restricted region are shown as a function of sample number. Data suggest the wells are diverse, both in terms of average response as well as variability through the lateral. Figure 3 illustrates the summed FIS response (divided by 10e6 for convenience) vs. average stabilized daily production over a two month period. Clearly the eventual relative production from these wells could have been anticipated immediately after drilling, and actual production statistics from future wells in the area can be reasonably predicted from this calibration set. Furthermore, contributions to the total production from specific portions of the wellbore can be ascertained, which might influence completion strategies. For instance, approximately 23% of the produced gas from well 4 appears to originate from a single, contiguous 200 ft measured depth section of the 2600 ft lateral, and approximately 50% of the gas is generated from 600 ft or 23% of the horizontal section. Finally, measurement of the intrinsic gas content of the samples distinguishes between wells that have been damaged or improperly completed from those that were drilled in a gas-poor section of rock.
Putting it all Together: An example that utilizes both DQMS data and advanced cuttings analysis is presented in Figures 5-6. The following discussion concentrates on an interval at approximately 8960-9110 ft. This zone displays a prominent DQMS anomaly characterized by C1-C7 species and gas ratios that suggest light oil or condensate (Fig. 5; Panel A). A slightly drier anomaly occurs within a restricted zone and may represent a discrete gassier phase (or gas and oil) as suggested by FIS data described in a subsequent paragraph. Water-saturation indicators (e.g., benzene/toluene and benzene/cyclo-hexane) suggest trace movable water within this section, and presence of the sulfur species CS2 and COS suggests that sulfur bearing volatiles may be produced.

is present as well, particularly in the thin drier gas or mixed gas-oil interval. XRF elemental data and element ratios (Fig. 5; Panel B) indicate that the main zone of interest is a mixed siliciclastic and carbonate (dolomite and limestone) section with both biogenic and terrestrially derived silica (chert and detrital quartz, respectively). Petrographically, the interval is dominated by fractured, cherty carbonate.

of anoxia and the presence of organic matter. The gamma ray correlates fairly well with sulfur, given the differences in sample spacing, consistent with the above interpretation. Petrographic observations indicate the presence of mature oil-prone source rock in some samples. Phosphorus is present, in this case related to the presence of apatite, and is potentially indicative of near-shore upwelling environments with high surface productivity. Arsenic is also generally associated with nutrient rich depositional environments. Mineralogical Continued on page 18 Âť

trends were verified independently via QEMSCAN. This technique creates a mineral composition map of a petrographic thin section using a rastering SEM based EDS-XRF system and software (Fig. 6). FIS data (Fig. 5; Panel C) indicate species to C11-C12 with bulk mass spectra that resemble light oil. Upper moderate gravity light oil inclusions are abundant in chert, indicating high petroleum saturation. Some gas-condensate is noted as well, suggesting the possibility of a dual phase reservoir and consistent with DQMS observations above. FIS C1 and C7 relationship imply two discrete charges (oil and drier gas). Sulfur species are present in FIS data, as previously described for mud gas data, suggesting that some sulfur species (and minor CO2) may be produced from this zone. These species are interpreted to be of high temperature origin, and related to dry gas interpreted to have migrated into the structure from deeper in the basin. Thus, the combination of advanced mud gas analysis by DQMS and advanced cuttings analysis via integrated FIS, XRF and photography provides valuable and otherwise unobtainable information with broad application to petroleum exploration and development. Data can be used to help understand the key aspects of conventional and unconventional reser voirs that most commonly contribute to successful exploitation, and can aid in optimizing wellbores and completions to lower costs and allow for more efficient drilling campaigns.

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 “resource play” 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:

In Memoriam: Willson Willard Bell By John Oty, Green Valley, AZ Willson (Bill) Bell was born April 6, 1927 in Limon, Colorado and passed away on March 7, 2013 in Centennial, Colorado after suffering a stroke in January. He was the oldest of four children of Clinton and Dorothy Bell. After graduating from Limon High School in 1945, he enlisted in the U.S. Navy, serving until 1947. He attended Colorado University from 1948 to 1952, earning a B.A. in Geology. Bill married Temple Brown in 1955 and they remained happily married for 58 years. They had two children – David and Patricia. During his career, he worked as an exploration geologist for a number of companies, including Midwest Oil Co., W. C. McBride and Odessa Oil & Gas Co. In 1979 he was a principal in starting EXCOA Oil and Gas, Inc., a publicly traded company, and served as Vice President, Exploration Manager and Director. Bill was a longtime member of RMAG and served as Secretary in 1968, Treasurer in 1974, 2nd Vice President in 1981 and worked on a number of committees, including the golf tournament committee. He also was a member of the AAPG and the Wyoming Geological Association. In 1985, Bill and Temple joined the Peace Corps and served for two and a half years in Sierra Leone, Africa – he as a geologist helping to develop potable water and she as a nurse.
Bill was active in many other volunteering areas throughout Willso his life. He served his church as on M a Sunday school teacher and served as President of his Home Owners Association for many After g years, but his favorite volunteer Navy, serving until 1947. work was at the Denver Metro CareRing food bank.

RMAG Luncheon Programs – June 5th and July 10th
“Honing the Zone” or “Just Let Me Drill it”: The Trade-Offs in Drilling the Perfect Horizontal Well By K.C. Oren, Horizontal Solutions Int’l (HSI TrueTime™ Services), kcoren@horizontalsi. com, member: AAPG, SPE, RMAG, HGS, AGS, PAPG, OGS, June 5
We will explore the trade-offs of staying in the targeted zone (sweet spot) by carefully steering the well and monitoring every move along the way versus drilling ahead for maximum ROP (rate-of-penetration) and less NPT (nonproductive time).
The personalities of engineers and geoscientists are typically very different. And when it comes to corporate risk/reward assessment, company incentives for these individuals are often counter to the overall end goal: higher IP and superior well performance among the peer group. For example, drilling team metrics and operating personnel objectives are often counter to maintaining geological target objectives (staying in zone) and achieving maximum overall production (highest possible EUR). As a result, these divergent drivers may create dichotomies between individual personas due to personalities, personal motivation and company goals, and therefore create conflict between otherwise closely aligned asset team members. We will explore the trade-offs of staying in the targeted zone (sweet spot) by carefully steering the well and monitoring every move along the way versus drilling ahead for maximum ROP (rate-of-penetration) and less NPT (non-productive time). The goal of the paper is to provide a basis for better understanding what makes the drilling team itchy and uncomfortable versus the overall benefits of staying in zone…sometimes the extra deliberations or seemly costly modifications in a drilling plan do in fact pay big dividends…or do they? What both engineers and geologists need to know! Continued on page 40 »

The Sedimentology of Mudrocks: Organics, Organisms, and Occasional Occurrences
By Jeffrey A. May, PhD, Chief Geologist (Retired), EOG Resources, July 10
At the sea floor, suspension and deposit feeders (e.g., polychaetes and nematodes) may ingest the organics, reducing carbon content.
Mud deposition often has been attributed to slow fallout from suspension into low-energy, frequently anoxic, settings. In reality, sediment delivery and resulting organic content, grain size, and lithology are quite variable. Understanding sedimentologic processes help us better describe mudrock cores and interpret stratigraphic and basinal variations in reservoir quality and mechanical properties. Compositional variability reflects the complex interaction of biologic productivity, detrital input, organic preservation vs. destruction, and diagenesis. Intrabasinal biogenic material includes calcareous and siliceous hard parts of zooplankton and phytoplankton; cellular matter from algae, bacteria, spores, and pollen; fecal pellets; and feeding nets. Much of this matter sinks rapidly as aggregates, not individual particles, removing it from shallow, oxidizing waters. At the sea floor, suspension and deposit feeders (e.g., polychaetes and nematodes) may ingest the organics, reducing carbon content. Biogenic influx is not constant. Extrabasinal carbonate and/or siliceous detritus vies with, and often overwhelms, intrabasinal input. Much extrabasinal material is delivered under the influence of storm waves or density flows. Storms suspend and mold bottom sediment, variably producing waveenhanced sediment-gravity flows, graded tempestites, and hummocky and wave-rippled bedforms. Hyperpycnal deposits form as rivers transit through flood cycles. Ignitive events yield slides, slumps, debrites, and turbidites. Sedimentary structures produced by these various processes may be difficult to recognize or interpret. They typically are subtle, due to small variations in grain size and/or post-depositional bioturbation, or very thin. Thus, the paradigm of grain-by-grain settling of mud onto a deep, quiet, stagnant sea floor is being revised. The concomitant slow, continuous rain of organic matter is unlikely. Instead, mud accumulates under dynamic conditions. Active bottom currents are frequent. Persistent bottom-water anoxia is overestimated; diminutive, often “cryptic”, bioturbation is common. These interacting processes produce deposits of varying reservoir quality and cycles of various frequencies - seasonal, climatic, tectonic, and eustatic – that can be interpreted in core, outcrop, and well logs. Consequently, the study of mudrock sedimentology is generating new concepts that can be applied to rock description and appraisal and mapping of drilling targets.

The updated assessment for the Bakken and Three Forks represents a twofold increase over what has previously been thought. These two formations are also estimated to contain a mean of 6.7 trillion cubic feet of undiscovered, technically recoverable natural gas and 0.53 billion barrels of undiscovered, technically recoverable natural gas liquids, a threefold increase for both resources. The geological foundation that underpins the assessment was facilitated by data provided by the North Dakota Geological Survey, North Dakota Industrial Commission, Montana Board of Oil and Gas, and multiple industry groups working in this region. This new information and data allowed USGS to develop a more robust geologic model and understanding of the petroleum system of the Bakken and Three Forks Formations. See http://pubs.usgs.gov/ fs/2013/3013/ to download a pdf of the assessment.

Application of Structural Methods to Rocky Mountain Hydrocarbon Exploration and Development Edited by C. Knight, J. Cuzella, & L. Cress
Co-published by Tulsa, OK and Denver, CO www.aapg.org/www.rmag.org
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. As a means of addressing complex interrelationships between structural geology and hydrocarbon exploration and development, the editors are pleased to present this compilation of key papers.
