# Robbie Gries

Robbie Rice Gries is an American petroleum geologist who was the first female president (2001–02) of the American Association of Petroleum Geologists (AAPG), president of the Geological Society of America (2018–19), and founder of Priority Oil & Gas LLC. Gries is noted to have made some influential progress for women in this field. In 2017, Gries published the book titled Anomalies—Pioneering Women in Petroleum Geology: 1917-2017. Gries is recognized as an unconventional thinker when approaching geological concepts and applications.

## Early life

Gries was born in San Antonio, Texas in 1943 and her full birth name is Ruth Roberta Rice. She has used her nickname, Robbie, most of her life. Her father was a gulf shrimper and Robbie was delighted to collect marine fauna for her zoology classes from her father's boat. Gries, on vacations away from the Gulf Coast was fascinated with rocks and collected them on journeys, but never heard the word "geology" until she was a sophomore in college.
Gries graduated from Del Mar College, where she had her first geology courses and developed a passion for the science. She envisioned her next steps to be at the University of Texas but her junior credits would not transfer so she moved out of state to study at the Colorado State University where she was the first woman to graduate with a degree of geology. Gries then moved to The University of Texas where she completed her master's degree.
During graduate school, Robbie Rice married John Charles Gries and had her first and only child (Lynn Margaret). After graduate school The Grieses moved to Wichita, Kansas where he joined the geology faculty at Wichita State University.

## Career

Eventually divorcing, in 1973 Robbie Gries moved back to Colorado, and gained employment with Texaco, Inc. She was hired during the Affirmative Action push for oil companies to fulfill diversity employment plans and was nicknamed "token" in her office. Her areas of exploration included New Mexico, Colorado, and Wyoming. In 1977 she accepted a job with Reserve Oil and Gas in Denver. At that time she and the female geophysicist at Reserve became the first female members of the Denver Petroleum Club, breaking another barrier for women. The Denver Petroleum Club was the first such establishment in the US to accept female members. Gries, in 1980 became a consultant and was retained by Mabee Petroleum (Tulsa, Oklahoma), Amarex Petroleum (Oklahoma City), and Burnett Oil and Gas (Fort Worth) over the next ten years. In 1993 she facilitated a merger between Skaer Petroleum and Pease Oil and Gas and became an officer in the consolidated company. In 1994 she resigned and crafted her own startup; Priority Oil & Gas, LLC. Priority began buying oil and gas properties and new leases and was dedicated to exploring, operating and drilling, primarily in Kansas, Colorado, and Wyoming.
In 2001, Gries was elected president of AAPG. In this time, she visited 44 countries and led the development of international oil research.
Currently, Gries remains the president of her company.

## Awards and recognition

Gries has been an officer and committee chair for the Rocky Mountain Association of Geologists (RMAG). She received their Distinguished Service Award (1987), Honorary Membership (1989), and Special Humanitarian Award (2006).
Gries was a Director for the Colorado Oil and Gas Association, Denver, CO, from 1993 to 2009. She was also a member of the Colorado and International Women's Forum from 1985 to 2009 and was President of the Colorado Forum in 1997. She received the Woman Leader of Excellence Award in 1997 from the Colorado Women's Leadership Coalition. In 2018 she selected as one of the Top Women in Energy by the Denver Business Journal.
The American Association of Petroleum Geologists (AAPG) has awarded her for Distinguished Service (1991), Honorary Membership (1998), the Leverson Award for best technical paper in the Rocky Mountain Section (1985). Prior to becoming the President of AAPG she Chaired the Distinguished Lecture Committee and expanded it globally; Chaired the Ethics Committee, created the Diversity Committee (now PROWESS), Chaired the Advisory Committee, and was General Chairman for the Annual meeting in 1994 in Denver, Co. She is a Trustee Associate and a member of the Corporate Board for the AAPG Foundation. In 2012, Gries was awarded the Michel Halbouty Award for Outstanding Leadership. The award recognizes petroleum geologists who have displayed exceptional leadership and remarkable service in a corporation, research facility or academic institution. Gries is the first woman in history to have received the award.
Gries was one of the founders (2001) and officers of GeoScience World, McLean, Virginia, an internet resource for the geosciences, an electronic aggregate of geoscience journal publications and books made available globally to universities, corporations and individuals.
In 1997, the Colorado Women's Leadership Coalition awarded Gries with the Woman Leader of Excellence Award. This prestigious achievement signifies the impact she has made for women in her field. RMAG awarded her for technical papers or presentations in 1980, 1982, and 1986.
She is a Fellow, past treasurer and President-elect (2018–19) of the Geological Society of America.
