PRESIDENT’S LETTER By Marv Brittenham

More on Career Paths… and the 800 pound gorilla

IT’S PERSONAL

Again, not much has changed over the past month as you can see from the EIA spot price chart; the price continues

think. One way or another, this price stress is affecting us personally, directly or indirectly. My concern is for the individuals affected, not RMAG as an organization. We are in the process of putting a five year Strategic Plan into place and I want to assure you that RMAG has staying power and good prospects for the future! Through the good management of the Board of Directors, our volunteers and the Staff we have built an appropriate “rainy day fund”. I’ll review the Strategic Plan in a future letter, but for this month I want to elaborate on the “advice column” from last month. If you missed that column please start there by downloading the April Outcrop which outlines the top ten steps for survival and success in a career in the energy industry. How you utilize those strategies will vary with your situation. There are a large number of RMAG members who are not employed in the energy industry or maybe not directly affected by the low oil price environment. But we are a community of geologists, that’s one of RMAG’s core strengths. This

to fluctuate around the $50 range. The news mostly reflects the negative effect this is having on corporations, particularly those with tight borrowing bases. It’s good to see an appearance of price support around that level, but as time stretches on this looks more long term than we’d like to

information is also important, for instance, if you’re helping a friend or family member though a hard time. Most of these strategies are common to any career, but particularly those that are based on any commodity and therefore cyclical by nature. If you’re starting a career or are a student in the geosciences you have the benefit of foreseeing the reality of a cyclical commodity based career. But, virtually any career opportunity will involve uncertainties and cyclic economics. So, even if you choose a geoscience career in some other realm read on!

regular contact, giving encouragement or advice, or simply having lunch or coffee. Stay engaged and stick to a daily work schedule by networking and exploring opportunities.

4. Be patient Your career is a long term proposition. If you have prepared for a break in employment take time to find the best opportunity. Geoscience in the energy industry is still an exciting and rewarding career. The current price stress will abate, there are good times ahead.

2. Conduct regular self-assessments Is petroleum geoscience your passion; are your skill sets and your track record desirable and marketable; are you contributing to the team; are you indispensable to your employer? Your employer does regular performance reviews. So use that review for self reflection. This is part of owning your plan because no one else will!

5. Have an agenda for success in your career Lay out a definitive plan for your career that fits your skill set and passion. Pursue opportunities that compliment your agenda. Have some flexibility because technology changes quickly! Stay active in professional societies. This will help you remain current and will provide networking opportunities.

3. Plan for the best, prepare for the worst Build a one year rainy day fund and have a plan to cut expenses. This sounds difficult and it takes self-discipline; but this is so important in enabling your options. Continuously explore alternative employment opportunities. Have some options in mind at all times. Never assume your current job is

6. Find a mentor Choose someone who can advocate for you, advise you and help you through good and bad times.

This is a great proactive strategy whenever you make a change or start a new job. Mentors have been instrumental in my career and often sponsored me towards new positions or new jobs. Ask any successful geologist and they’ll accredit a set of mentors. 7. Training and education Find a seminar on job hunting. It’s not a natural skill and we don’t do it often; so get some professional help. If you have the time and financial capability consider further educational opportunities, advanced degrees or business training. If you need to update your skill set professional society short courses like those from RMAG or AAPG are a great way to keep up. 8. Take control To own your career you need to be more than a geologist. That means you should understand the business and develop your educated view of the risks and opportunities including the company that employs you. You have some unique insight as to your employer’s future so keep an open and not overly optimistic view.

Be flexible You may need to make some difficult decisions regarding a future employer, the salary, the job, the location or even a different career. Keep an open mind. Often a small step back in your career agenda may ultimately buy you the time and means to your desired career path. Relocating can be painful, but many of us have and actually gained unforeseen opportunities from it. If you’re passionate about the Rockies there are ways to return.

10. Consider transitioning to another career During the 1986 downturn RMAG and the state collaborated in a career transition center that helped those geoscientist who were interested in changing find other opportunities. There are many teachers, environmental geoscientists and others who found their calling in a new career at that time. When you’re doing your self-assessment consider if you need a major change. The best bottom line advice is to own your career. Be proactive and prepared. Don’t let circumstance or fate determine your future! I would appreciate any feedback. If you have questions I’m available at president@rmag.org and at most RMAG events.

RMAG LUNCHEON PROGRAMS Speaker: Daniel A. Krygowski — May 6, 2015

Pattern Recognition in a Digital Age: A Gameboard Approach to Determining Petrophysical Parameters Daniel A. Krygowski, Robert M. Cluff The Discovery Group, Denver, CO, USA determine the parameters needed in Archie’s water saturation equation(1942), so that the parameters and associated well log data can be used to calculate water saturation in much more detail and with more precision than before. An extension of those graphical techniques is shown here, where Hingle, Pickett, and Buckles (1965) plots (Morris and Biggs, 1967) are displayed simultaneously. In this “gameboard” display in Excel (© Microsoft), data is displayed on all the plots. The selection and modification of computational

Graphical pattern recognition interpretive techniques have been part of petrophysics since quantitative interpretation began, as a way to quickly determine properties of interest with a minimum of calculations. When calculators and computers were introduced to petrophysics, the focus of the techniques changed from determining the quantities themselves to determining the parameters needed to calculate those quantities. As an example, Hingle plots (1959) and Pickett plots (1966, 1973), first used to quickly determine water saturation for a few points in a reservoir, can now instead be used to

Daniel A. Krygowski is a Senior Petrophysical Advisor at The Discovery Group, in Denver, Colorado, USA. In this role, he has worked petrophysical interpretation projects in a variety of international and US domestic locations. Currently he is spending the majority of his time providing and developing courses in basic and intermediate openhole petrophysics. The courses include the common instructor-led formats, as well as longer-term, lower intensity formats that allow participants to spend more time with the course material while delving deeper into areas of personal interest. Since the late Cretaceous, Dan has taught the AAPG Basic Well Log Analysis course with Dr. George Asquith. In 2004, the AAPG published Basic Well Log Analysis, co-authored by Dan and George, with Steve Henderson and Neil Hurley, the second edition of George’s similarly-named book which was one of AAPG’s all-time best sellers. Dan earned a BA in Physics from the State University of New York at Geneseo. He then earned MS and Ph.D. degrees in Geophysics from the Colorado School of Mines, where he focused on petrophysics under George R. (Dick) Pickett. After completing his formal education, Dan worked for Cities Service Company (now part of Occidental Petroleum), Atlantic Richfield (now part of BP), Petrophysical Solutions, Landmark Graphics (a Halliburton company), and Chevron. At several of those companies, he held positions in petrophysics and petrophysical software development, with both technical and management responsibilities. He joined The Discovery Group in late 2006. Dan has been active in the Denver Well Logging Society, serving two terms as Director, and terms as Vice-President Technology, and Vice-President Membership. Dan is a member of SPWLA, AAPG, SPE, SEG, DWLS, and RMAG. OUTCROP | May 2015

parameters is immediately reflected all plots, leading to a more coherent prediction of those parameters than from the same plots used independently. The Pickett plot, with bulk volume water lines added as suggested by Greengold (1986), Hingle plots with additional bulk volume water lines, and Buckles plots (both linear and logarithmic scales) can predict in a common environment the following parameters: Matrix parameters to derive porosity from density or sonic logs, Archie porosity (cementation) exponent, m, saturation exponent, n, and water resistivity, Rw, and irreducible bulk volume water, BVWirr. The display uses three common plots (Hingle, Pickett, and Buckles) not commonly displayed simultaneously, adds bulk volume water lines to the Hingle plot, and has the plots linked so that changes made to the parameters displayed in one plot are reflected in the other plots and the computations derived from those plots. By being able to change the values of any of the parameters while seeing how those changes impact the other parameters and the calculated porosity, water saturation, and bulk volume water, the user can quickly try different interpretive scenarios and determine which results best honor all the data at hand.

Core-scanning also provides rich chemical datasets, and in the case of XRF yields up to 30 elements, including majors and traces – this greatly exceeds that of industry standard core gamma scans (K, U and Th). The integration of both core scanning techniques (XRF and DECT) can also be used to generate

Recent advances in core-scanning technology have provided the necessary data to model unconventional reservoirs at extremely high resolution using non-destructive techniques. These include Dual Energy Computed Tomography (DECT) and X-Ray Fluorescence (XRF), which measure bulk density and chemical composition (rock matrix), respectively. These fine-scale core scanning methods resolve geologic thin-beds (cm-scale), and output data can

high-resolution reservoir models. Bulk density and elements from XRF scanning are used to solve for mineralogy, total porosity, clay bound water and effective porosity. Continuous kerogen estimation is also possible by calibration of elemental proxies, and is critically important for organic-rich source beds. Summation of the calculated mineral volumes and kerogen, if present, defines solid-phase matrix density, which can be combine with bulk and fluid densities to calculate reservoir storage along with bound versus free fluids in the reservoir. This multimineral model is calculated using core scanning results; hence has utility for comparison to log-based petrophysical solutions. Ingram, Wesley C., Ph.D., is a geochemist at Weatherford labs in Golden CO, with a primary focus on X-Ray Fluorescence (XRF) technology and interpretation of elemental data. His expertise includes sedimentary geochemistry, biogeochemistry, and petrophysics. Prior to Weatherford, he worked at Devon Energy in exploration and development as a geologist and petrophysicist. Within Weatherford, he is involved with developing new XRF core scanning services and reservoir evaluation techniques. He received his undergraduate and masters from Florida State University in Geography and Geological Sciences and his doctorate from University of North Carolina-Chapel Hill in Oceanography.

aunch your summer outdoors in beautiful Colorado by attending the first field trip of the 2015 season! Our state is home to many troublesome highways, and the Colorado Department of Transportation (CDOT) geotechnical professionals work to anticipate and correct hazards presented by mass-wasting processes. Colorado State Highway 133 (SH 133) connects the communities of Carbondale and Hotchkiss, cutting across the northwest corner of Gunnison County. As it climbs over Vol. 64, No. 5 | www.rmag.org

McClure Pass, the eastern side offers stunning vistas of the Elk Mountains above Marble, but one’s eyes are also drawn to extensive netting on the road cuts to catch rockfalls. Descending the pass on the west, landslide terrain is everywhere and, at one point, cars are required to slow to 20 mph to skirt a particularly insidious slide. Continuing west, one encounters one of the largest landslides in the state; it necessitated a realignment of the highway to the other side of Muddy Creek. Watch out for rocks in the road as you cruise along the edge of Paonia Reservoir.

The long-term goal that CDOT has in mind is periodic scanning/ monitoring of its highway corridors through time using change-detection remote sensing methods to identify features that may be moving.

remote sensing method. An aerostat was used to collect photographs of the slope at different points in time to create a model that compared past and future photographs to detect movement (Figures 1 & 3). The use of the aerostat makes data collection a fairly quick process and it has the potential of being an efficient way of moving through highway corridors effected by geological hazards. For our trial, the aerostat took photographs along a 7-mile stretch of SH

A photogrammetry project that took place on SH 133 was part of a series of experimental projects launched by CDOT to evaluate methods of remote sensing that could be used to detect small-scale slope movements that lead to rockfall. The long-term goal that CDOT has in mind is periodic scanning/monitoring of its highway corridors through time using change-detection remote sensing methods to identify features that may be moving. If identification of potentially unstable slope features is successful, this information can then be used to target mitigation, justify additional monitoring or instrumentation efforts, and help guide decision making processes with respect to geohazard management statewide. This particular project explored the option of using photogrammetry as a potential change-detection

133 in June and September of 2014. These photographs were then processed using photogrammetry methods to detect changes or displacement of individual features within the slopes. The aerostat operation, photo acquisition, and processing were provided by Sky Sentry. Prior to collecting the photographs, several control points were installed through the corridor (6inch diameter white spheres/globes that are anchored into the ground. The control points were anchored into features in the slopes that were believed to be stable and also anchored into preset bolts in the road. After installation, these control points were GPS surveyed which allow the photographs (and features within the photographs) to be geo-referenced. Once the control points were set and surveyed, the aerostat was inflated and driven down the highway at a rate of 4 mph. A DSLR camera was attached to the aerostat and was programmed to take pictures at a rate of one photograph every two seconds (Figure 2). The camera was controlled by a remote which allowed it to point in any direction on the slope. The camera was used to achieve a target Vol. 64, No. 5 | www.rmag.org

of approximately 50 percent horizontal and vertical overlap of the images. Sky Sentry processed the photographs using AGISoft PhotoScan Pro, which generates a mesh that models the slope surface. To detect changes/displacement in the slope materials, the model from each run is compared using the program Cloud Compare. Sky Sentry found that there were some variables that affected the accuracy of the models and made it difficult to detect movement of individual features. These variables included changes to the vegetation cover changes in snow cover, which lead to inaccurate readings of the actual slope surface (i.e. soil and bedrock). Despite these drawbacks, the photogrammetry method proved to be an effective tool that can be used to detect displacement within a slope, and the method can be improved with increased overlap and shorter distances for data collection. In addition, the aerostat proved to be a useful method for collection of the photographs that are used for processing. CDOT intends to continue researching different methods of remote sensing

SH 133 ROCKFALL HAZARDS

The SH 133 corridor from Paonia Reservoir (approximately MP 23) to the east side of McClure Pass (MP 45) has historically been characterized by a high rockfall hazard (Figures 4 - 7). CDOT first initiated a Rockfall Hazard Rating System in 1994 (Andrew, 1994). When the Rockfall Program completed rating and ranking all of their slopes state wide, 4 cuts within this stretch of highway ranked in the top 20 most hazardous rockfall sites in the state (out of 752 sites). A total of 63 rockfall-related vehicle accidents were reported on this stretch of highway from 1976 to 2012. Based on discussion with maintenance personnel that work in the region, we understand that rockfall occurs on a daily basis through this corridor; with increased activity during the spring snow melt

Our program is frequently responding to rockfall emergencies in the corridor (multiple times a year). The rock formation present in most of the cuts where frequent rockfall occurs is the Cretaceous Mesa Verde Formation – interbedded sandstone, siltstone, shale, and claystone (with coal at depth) (Ellis & Freeman, 1984; Goodwin, 1968). The main geological conditions present that contribute to a high rockfall hazard in the corridor include differential weathering and kinematically admissible plane shear failures (i.e. rock slides). Several of the rock

Vol. 64, No. 5 | www.rmag.org

cuts are characterized by layers of massive, strongly cemented sandstone that exceed 20 feet thick which are underlain by layers of very low strength, slake susceptible shale, siltstone, and claystone. Over time, repeated wet and dry cycles and freeze thaw cycles result in softening and differential weathering of these weaker units. Overhangs created in the overlying sandstone units from this differential weathering process frequently measure 10 feet or more. The most hazardous cuts are characterized by a highly persistent joint set that dips between 70 and 80 degrees out of the slope face; and strikes subparallel to

Lead Story involved design and construction of nearly 300,000 square feet of rolled cable net over the rock cuts on the east side of the pass to reduce the potential for rocks to launch into the roadway and to help direct falling rock and rockslides into the catchment ditch. The project also included installation of tensioned rock anchors to improve the stability of thick sandstone slabs, and installation of shotcrete and rock reinforcement to protect slake-susceptible beds of low strength shale from weathering and erosion. From 2013 to 2014, CDOT managed the design of additional rockfall mitigation for the cuts

adjacent to Paonia Reservoir (MPs 24 to 25) and this project is expected to go into construction this spring and summer. This project will include installation of over 57,000 square feet of anchored mesh to retain over-steepened colluvial deposits and interbedded units of sandstone and shale. This will be the first application of anchored mesh by CDOT along a state highway for rockfall mitigation. Trim blasting will be used to remove over 5,000 cubic yards of massive, undercut sandstone slabs within two rock cuts. In addition, a 1,000-foot long soil nail wall is going to be constructed at the base of one of the cuts to allow for construction of a 25-foot wide rockfall catchment ditch.

the cut slope face. As differential weathering removes support from the overlying sandstone slabs, large-scale failures along these joint planes occur initiating rock slides with volumes on the order of hundreds to thousands of cubic yards. More recently, the CDOT Geohazards Program has initiated design and construction of rockfall mitigation to proactively reduce the overall hazard within the corridor. From 2012 to 2013, the CDOT Geohazards Program managed the design and construction of rockfall mitigation on the east side of McClure Pass from MPs 44 to 49. This project

SH 133 EMBANKMENT FAILURES AND LANDSLIDES

In addition to rockfall, the SH 133 corridor is also prone to landslides and embankment failures. Dozens of landslides have been documented and mapped along the highway corridor (Goodwin, 1968) and several of these have had a direct impact on the highway. Of particular note is the Muddy Creek Slide Complex on the east side of Muddy Creek. This geomorphic feature is a massive landslide complex that measures over 13,000 feet long and 7,000 feet wide; extending from the base of the Ragged Mountains down to Muddy Creek adjacent

The Wasatch Formation is composed of layers of claystone, mudstone, shale, sandstone, and conglomerate. Geotechnical investigations by the CDOT Geotechnical Program have found that weathered claystone deposits of the Wasatch Formation within active landslides are characterized by shear strengths with friction angles as low as 20 degrees.

Muddy Creek Slide Complex in April of 1986 (Appel & Butler, 1991). conditions combine to create unstable slope conditions and landslides. In 1986, rapid movement of the central lobe of the Muddy Creek Slide Complex resulted in the formation of a dam of East Muddy Creek, and resulted in damage to SH 133 between approximate MPs 29 to 31 (Figure 8). Three active portions of the slide complex were documented by the Colorado Geological Survey; and all three exhibited movement from 1986 to 1987 (CGS, 1987). On April 26th, movement of the central lobe was on the order of 9 to 12 feet per day, which continued until June of 1986. Total lateral displacement of the central lobe was measured at 230 feet, and the northern lobe moved approximately 75 feet (Appel & Butler, 1991). Movement of the landslide lifted the elevation of the stream bed of Muddy Creek approximately 30 feet and damaged SH 133. CDOT Maintenance personnel continually worked to remove material from the toe of the landslide; which permanently changed the OUTCROP | May 2015

gradient of East Muddy Creek in the area (Appel & Butler, 1991). Currently, two large landslides have been identified that have a direct impact on SH 133. One is at MP 40.5 just west of McClure Pass, and a second has been identified at MP 39.7 (Figures 9 & 10). The CDOT Geotechnical Program has been involved at the MP 40.5 landslide since 2005; and have only this past year been approved for funding to conduct a subsurface investigation, laboratory testing, and instrumentation program to characterize the landslide. Conceptual level mitigation alternatives have been developed to mitigate the landslide and selection and final design of the preferred alternative is still in progress and dependent on construction costs and available funding. The second landslide at MP 39.7 has not been studied in detail at this time. In addition to landslides, the corridor is also prone to shallow embankment failures.

You’re invited to the premiere of a new movie-“A Brief History of Colorado Though Time” -- immediately before the AAPG Convention’s Opening Ceremony in Denver on May 31. This movie shows how Colorado’s famous landscapes evolved through geologic time.
