PRESIDENT’S LETTER

By Larry Rasmussen

‘Right-hemisphere’ Geology My daughter is a great artist.

I’m not. Maybe that’s one of those things that skips a generation, because her grandparents are also good artists. I’m not sure I could sketch my way out of a paper bag, but my daughter can create these beautifully elaborate three-dimensional drawings that can literally raise the hairs on the back of my neck. No joke. She has genuinely enviable talent, one I might be good at if I had put as much effort into it as she did when she was first honing her craft. Yet, I am more than happy to sit back and marvel at other people’s artistic abilities much in the same way that I love to go see bands play but wouldn’t want to be the one performing on stage.

I was always told that one of the skills that makes a good geologist is the ability to channel the right side of the brain, the hemisphere that controls imagination and creativity. I suppose that I’m creative, or at least I try to be, but I wouldn’t consider myself an artist. One of my mentors over the past 10 years has repeatedly emphasized hand-drawing structural contour maps and cross sections, and I have improved at it over time with lots of practice. Drafting maps and cross sections by hand is something that I find both relaxing and rewarding, and it’s probably about as close as I come to OUTCROP | May 2017

Stone’s memoir from 2013 featuring his watercolor titled, “Front Range Pumpers” artistic expression as a geologist.

It goes without saying that handdrawn structure maps and cross sections are generally far superior to any that are generated with computer software.

The importance of creative, right-hemisphere thinking to 8

geology is compellingly presented in a 2013 article by Don Stone titled “Using Freehand Three-dimensional Drawings to Clarify and Verify Subsurface Structural Interpretations.” It takes geologic artistry to the next level by

integrating structural contour maps and cross sections into hand-drafted 3-D block diagrams as a way of validating complex subsurface geologic structures. Regarding 3-D visualization, Don states: Many geologists have difficulty with 3-D perception, apparently more because of neglect during their formal education and later inattentiveness than because of an absence of innate ability.

Overemphasis on today’s industry demands for computer skills (a left-brain domain) and lack of encouragement from mentors probably contribute to this neglect. However, improvement in spatial perception can be developed with dedication and practice.

POSITIONED FOR GROWTH

In other words, all geologists have the ability to channel the right sides of our brain – we just have to work hard at it and practice, practice, practice.

Reading Don Stone’s 330-page autobiography, Memoir of an Independent Geologist: Navigating the Oil Patch Minefields, I was struck by the variety of non-geologic artistic skills that Don possesses. He paints, sculpts, draws, acts and sings, and he plays the drums and piano. If you’ve been to the Rockbusters Ball that RMAG puts on every year in November, Don is the guy playing drums in the jazz ensemble, and he’s been doing it for 50 years! Don’s artistic talents, and his ability to think in three dimensions has no doubt played

an experienced seismic interpreter, Larry Malarin, who taught him how to construct seismic depth sections and how to integrate surface geological mapping, well data and 2D seismic into three-dimensional geologic interpretations. Becoming expertly skilled at seismic interpretation and structural mapping served Don well throughout his career.

Don made the move to Denver in 1961 and worked for Franco Western Oil Company as district geologist (1961-65), as exploration geologist with Chevron (1965-68) and, finally, as exploration geologist with Baumgartner

a large role in his success as a structural geologist. It seems that Don’s career as a geologist has been greatly enhanced by constantly exercising the right side of his brain.

Don grew up in Garden City, New York and spent his summers Upstate on the northwest shore of Lake Champlain. There, he and his cousins would collect fossils from the Ordovician Chazy Limestone and the Canajoharie Shale.

Although this was his first exposure to geology, it wasn’t until his junior year at Hamilton College that his professor and mentor, Phil Oxley, encouraged him to

consider a career as a geologist.

Things moved quickly following graduation in 1950. In 1951, Don applied for and received the Eleanor Tatum Long Graduate Scholarship in Structural Geology at Cornell University. He completed his MS thesis on tectonic breccias of the Taconic Orogeny during his first year. In the summer of 1951, he accepted a position with SOCAL (Standard Oil Company of California, now ChevronTexaco) and moved to San Francisco. Over the next 10 years, Don worked in several SOCAL offices, including a short stint in Utah as a “party geologist” for a seismic crew.

During his time in the Sacramento office, Don was mentored by

Oil Company (1968-70). While he was with Baumgartner, Don was given the freedom to select areas of study to develop, assemble and sell drilling prospects. It was a unique and valuable learning opportunity, and he was engaged in everything from generating the prospect and acquiring leases, to negotiating and selling a readyto-drill prospect. These acquired skills prepared Don for the next phase of his career as an independent, entrepreneurial geologist.

In 1972, he struck out on his own, first as Sherwood Exploration Company, later as an independent consulting geologist, and over the next 30 years he developed and sold numerous successful prospects in the Rockies. Eleven of these prospects are described in detail in Don’s memoir and make for fascinating reading.

Over the span of his career, Don Stone contributed greatly to his field, publishing nearly 80 articles in peer-reviewed publications. He holds a particularly honorable record with RMAG, having published 20 articles in The Mountain Geologist, the most by any one author. I’ve read several of Don’s articles over the years (what I haven’t read, however, could fill a book!) and have always enjoyed his logical approach to addressing a particular hypothesis. Especially engaging are the ‘Discussion’ and ‘Reply’ articles in which Don either challenges authors’ opposing views or defends his own written work. However, one of my favorite publications by Don Stone is not so much an article as it is a work of art. This is his Wyoming

Transect, a 409-mile structural cross section that starts along the Wyoming Overthrust and proceeds across the Green, Wind River, Bighorn and Powder River basins and their intervening uplifts.

Don saw the Wyoming Transect as a challenging and enlightening exercise, and it was never meant to be a profitable venture, and, as such, took a back seat to Don’s higher-priority prospect generation. Between its initiation in 1985 and completion in 1987, the Transect was a labor of love. It was a compilation of 15 individual segments constructed from all available published geologic maps, well data and 2D seismic data. The Wyoming Transect was

PRESIDENT’S LETTER

OUTCROP | May 2017

Presentation of Wallace E. Pratt Award for best paper in the AAPG Bulletin (2002) by AAPG President Steve Sonnenberg, 2004. (Photo courtesy: Don Stone) raising four daughters with his wife of 65 years, I’m left with the conclusion that Don is the ultimate optimist. No task or skill was insurmountable as long as he believed that he could do it and as long as he properly applied himself. Challenging work was viewed as engaging and stimulating, and any ‘failures’ were seen as valuable learning opportunities. Along with the right-brained creativity that aided Don’s success in the oil patch is an underlying altruism.

Don has given back to the Rocky Mountain geologic community time and again through numerous publications and professional talks, service to RMAG (past-VP and President) and AAPG and, of course, the Stone-Hollberg Scholarship. Shortly before starting this piece, I was talking to Don on the phone and he was telling me that he is donating his archives to the 12

Denver Earth Resources Library.

He was enthusiastic about the notion that his life’s work might be useful to new generations of geologists. “I’m just so excited to think that my work might be able to help out younger geologists!”

Don’s memoir would be an interesting read to anyone in the business, but it is a particularly fascinating read to a geologist like myself. If you would like to buy a copy of Don’s memoir, you may get in touch with him directly via email.

To contribute to the Stone-Hollberg Graduate Scholarship in Structural Geology, please contact the RMAG Foundation.

Digital copies of the Wyoming Transect are still available from RMAG and all proceeds go toward the Stone-Hollberg Graduate Scholarship.

enthusiastically received at GSA and RMS-AAPG conferences in 1987. Hand-colored, hard copies of the Transect were sold to major and independent oil companies with offices in Denver, and it was used as a trading medium for seismic data as well as a critical lease in one of Don’s prospects.

In 2007, Don teamed up with John Hollberg to digitize the Wyoming Transect and offer it for sale to the geologic community.

Don decided to parlay the net proceeds from the sales of one of his finest artistic achievements to a graduate scholarship in structural geology. As he explains, he probably would not have been able to attend Cornell University without a graduate scholarship, and he would have missed out on the excitement and challenges of being a structural geologist in the petroleum field. Together, Don and John contributed a total of $40,000 to seed the Stone-Hollberg Graduate Scholarship in Structural Geology. The RMAG Foundation contributed an additional $10,000 and awards scholarships annually. This year’s scholarship was awarded on April 12 to Katrina Lucia Soundy, a Master’s student at New Mexico Technical University, whose thesis topic is titled, “Characterization of fault micro-structures from the Sawtooth Mountains and West Salton detachment fault, New Mexico and California.”

Pondering all of Don’s contributions, his career as a successful independent geologist and his varied artistic hobbies, all of which were conducted while

OUTCROP | May 2017

Area of Interest (AOI) in the basin center to quantitatively determine which log facies the wells transected. The percentage of feet drilled in each facies and the net thickness of each interval were compiled for each well in a database along numerous geological and production variables. Following compilation of the variables, correlation matrices were utilized to identify key geologic production drivers. The geologic drivers were then utilized to normalize the horizontal well dataset, creating subsets of horizontal wells drilled in areas of “similar” geology.

Results from the initial study show a very poor relationship between drilling in-zone and well

Over the past few years, the Middle Bakken play in the Williston Basin has evolved from delineation and step-out drilling to significant infill development.

As wells are being drilled at a faster pace, the need to understand the target zone is of greater importance.

This study presents a workflow for horizontal target optimization by utilizing correlation matrices coupled with log facies modelling, reverse-geosteering, and geologic mapping.

In this study, we created a regional petrophysical log facies scheme by employing a Principle Component Analysis (PCA) utilizing standard wireline log suites and core analyses. We then “reverse geosteered” 164 Middle Bakken horizontal wells in an

the reservoir in the AOI is relatively homogenous with regards to pore-throat size, and therefore permeability. In the second phase of the study, the same methodology for evaluating percent in-zone was applied to another portion of the basin where capillary pressure data showed the Middle Bakken to have greater pore-throat size heterogeneity. Results from the second phase of the study show that in regions of the Williston

Basin where pore-throat heterogeneity in the Middle Bakken is greater, in-zone drilling greatly improves well results.

While this study specifically analyzes well results in the Middle Bakken, the methodology of utilizing correlation matrices is readily applicable to many types of problems in petroleum exploration and development.

Preliminary versions of the restoration show approximately 67 km of translation or 26% shortening across the uplifts between the Denver and Piceance basins.

This synthesis indicates an early Laramide phase of differential subsidence starting at ~78 Ma and coincident with the arrival of magmatism related to encroaching flat-slab subduction beneath central Colorado. This was followed by a late Laramide phase of differential uplift starting at ~68 Ma and continuing episodically to at least 56 Ma. Onset of the early Laramide phase was marked by abrupt realignment of isopach trends with stratigraphic thicks developing in the Piceance and Denver basins separated by a thin across what are now South Park and the Sawatch Range. Onset of differential uplift during the late Laramide is indicated variously by the appearance of basement clasts in the Arapahoe Conglomerate at ~67 Ma, thrust deformation before, during and after intrusion of sills at ~63 Ma, fault gouge dated between ~68 and ~56 Ma, possible inflections in the apatite fission track elevation/age gradients at ~67 Ma, and deformation after the Laramie Fm. (~69 Ma) and before the South Park Fm. (~67Ma). The post-Laramide was marked by denudation and development of the Rocky Mountain Erosional Surface starting at ~45 Ma with localized increased heat flow and reburial of this surface beneath

In the spirit of past Colorado structural syntheses

by Hayden, Grose and Tweto, the aim of this project is to build a restorable transect following Interstate 70 east to west across the state. The section incorporates disparate data sets including potential field, seismic, well, thermochronology, and outcrop data, much of which has become available since a section like this was last published, to illustrate Colorado’s structural evolution. Restoring Laramide geometries involved using a projected top Cretaceous horizon as the upper bounding surface and a mid-crustal interface as the basal decollement/lower bounding surface. Refraction seismic combined with magnetotellurics provide evidence for the undulating mid-crustal interface at subsea depths between 12 and 29 km. In areas stripped to basement, missing stratal and structural cover geometries were projected into the section aided by low-temperature thermochronology and by analog to structures seen along strike. Ancestral Rocky Mountain structures were treated as early elements of the Laramide fault arrays, a premise supported by their reactivation during the Laramide. To permit restoration, the crooked section following Interstate 70 was projected into a straight profile oriented parallel to N65E, which approximates the Laramide transport direction. Recent wells and reflection seismic showing fault-bend folds, multiple bedding-parallel detachments, and stacked triangle zones guide the structural style and allow greater translation to be interpreted within the Laramide thrust systems. These data also

LEAD STORY

The Interactive Map Brings Together Groundwater Information from Several Agencies

SINCLAIR

PETROLEUM

Datasets used in the initial release of the atlas are WSEO groundwater well permits, USGS produced and environmental water quality, USGS hydrologic units with links to WWDC basin plan groundwater reports, spring locations digitized from USGS topographic maps and hydrostratigraphic characteristics of Wyoming’s bedrock geology by the USGS, WSGS and WWDC. Data from WSGS groundwater projects, such as the recent Statewide Groundwater Baseflow Study, are presented in the atlas as well. Reference base layers include roads, political boundaries, surface hydrology, township ranges and general geologic data.

“The groundwater atlas brings together commonly used groundwater information from several

A wide range of information about Wyoming’s groundwater can now be found on an interactive online map recently launched by the Wyoming State Geological Survey (WSGS). The new Groundwater Atlas of Wyoming will enable users to obtain basic groundwater data quickly, which will be helpful in an arid state where groundwater is used extensively for domestic, agricultural and industrial purposes.

“The groundwater atlas is another example of the Wyoming State Geological Survey’s efforts to provide ready access to important and useful geologic data and information to as many people and entities as possible,” says Tom Drean, WSGS director.

The online atlas offers an easy-to-use digital format that combines publicly available datasets from the Wyoming State Engineer’s Office (WSEO), the U.S. Geological Survey (USGS) and the Wyoming Water Development Commission (WWDC).

Research features of the map include the ability to search for WSEO groundwater rights by permit number, location, depth, use type and status.

Additionally, users can search USGS produced water sites based on water quality and obtain hydrologic information for specific geologic formations in Wyoming’s major river basins. The attributes for all features are viewable, and results of queries and manual selections are available for download in tabular format. When a user zooms in on a map location, more detailed data appears along with labels for well depth, static water level and water quality.
