Mark Longman is one of the most influential soft-rock geologists in Colorado. Having spent 40+ years doing geologic and petrographic consulting in the oil patch, he is principally known for his many contributions to understanding carbonate rocks in the Denver Basin and in Cretaceous strata of the western U.S. Additionally, his publications on the Niobrara Formation have become the established model for understanding that depositional system. Mark’s boundless curiosity and ability to integrate data from disparate fields set him apart, allowing him to make impactful contributions that extend beyond petroleum geology. Examples include his work on the sedimentology and Pennsylvanian-Permian eolian succession of the Front Range and the diagenesis of the Eocene Castle Rock Conglomerate—a contribution that impacted understanding of the landscapes of the Front Range and generated widespread media and public attention to the importance of opaline cements in local geomorphology.

Robbie Gries has blazed a trail for women in the geosciences throughout her lifetime. Her career is marked by a series of ‘firsts’. Robbie was the first woman to graduate with a geology degree from Colorado State University. She was one of the first women members of the Denver Petroleum Club and the first woman to chair the AAPG Annual Convention (Denver, 1984). Robbie became the first women president of AAPG in 2001 and later was recognized as the first women in history to receive AAPG’s prestigious Michel Halbouty Award for outstanding leadership. In 2018 to 2019, she served as President of the Geological Society of America. Robbie has spent a career making significant contributions to the practice of petroleum geology in the Rockies, but perhaps her most notable contribution is the authorship of a publication honoring women in the oil business, entitled “Anomalies: Pioneering Women in Petroleum Geology, 1917-2017”. This best-selling volume profiles the lives and accomplishments of women who have been forerunners and leaders in petroleum geology and, like Robbie, have given so much to our profession in countless and usually unheralded ways. For these contributions we are honored to present Robbie with the Robert J. Weimer Lifetime Contribution Award.

John Kerns entered the oil and gas industry in 1958 with Tenneco Oil Company. By 1968, he left Tenneco Oil to form Hegna, Kerns & Traut Geologists, a partnership that continued for over ten years. During this time, he participated in the discoveries of Buck Creek and Stanley fields, both significant finds that provided impetus for new exploration in the southern Powder River Basin and eastern Williston Basin, respectively. John served on the board of Double Eagle Petroleum & Mining and partnered with Tyrex Oil Company on numerous projects in the Rockies. Eventually he started his own firm, Kerns Exploration, where he continues to serve as CEO.
An active member of the AAPG since the early 1960’s, John served as president of the Rocky Mountain Section in 1979 and later as Association Treasurer during 1984 -1986. In 1988, he received the Distinguished Service Award, and in 1993, he received the Honorary Member Award. In 2005, he was the exhibit chair for the RMS meeting in Jackson. He remains an active member of the Wyoming Geological Association where he has served as President, Treasurer and committee head, and was awarded the Frank A. Morgan Award for his contributions to the science of geology.
2018
Donald Stone may in fact be the person with by far the most published papers dealing with hydrocarbon reservoirs in the Rocky Mountain region; in the range of about two dozen with him as a single author. He was for decades on the leading edge in terms of sharing his insights into both the nature of the reservoirs and their structural and tectonic history. There is little doubt that these published contributions, which date back to 1966, were read by many members of the RMS-AAPG and helped inspire them to generate their own new prospects, some of which probably resulted in the discovery of new and commercial hydrocarbon reservoirs. In addition to Don’s skills as a scientist and author, he generously donated his time and efforts to many geologic organizations active in the Rocky Mountain region. These include the AAPG and RMAG. As part of these efforts, he also organized and edited several books including the 1986 RMAG Symposium on the geology of northwest Colorado. Few in the Rocky Mountain geology community have been as technically motivated and as fruitful in sharing their knowledge as Don Stone. He is clearly deserving in receiving the Robert J. Weimer Lifetime Contributions Award.
2017
Ronald Johnson is a research geologist with the Central Energy Resources Science Center of the U.S. Geological Survey in Denver, Colorado. Ron has more than 40 years’ experience with the USGS on diverse projects and with many significant contributions to our understanding of the geology and energy resources of the Rocky Mountain region. Ron is a widely recognized expert on the overall geology (stratigraphy, mineralogy, geochemistry, etc.) and resource potential of oil shale in the Green River Formation and led the assessment team charged with evaluating the oil shale resources of the Piceance, Uinta, and Greater Green River basins mandated by the 2005 Energy Policy Act. He has led multiple Green River field trips, served in leadership positions with the AAPG EMD Oil Shale Commodity committee, assisted with the technical program at several Colorado School of Mines Oil Shale Symposia, and acted as a consultant and good will ambassador to oil shale researchers in China and elsewhere. As part of this career he has done pioneering work on coalbed methane resources (Wind River Basin), tight gas sands (Uinta, Piceance, Wind River, Bighorn, Crazy Mountain, Albuquerque, and Raton basins), and unconventional lacustrine tight oil resources (Uinta, and Elko Lake basins). His award for the RMS-AAPG Robert J. Weimer Lifetime Contribution Award is supported by his USGS coworkers and other geoscientists, who have benefited from his tireless efforts to describe and interpret the stratigraphy and sedimentary geology of the Cretaceous through Tertiary petroleum systems in the Rocky Mountain Region.
