Mrs. Susanne Leininger ’77

Susanne Leininger

Susanne Leininger is more commonly known throughout the petroleum industry by her nickname - Sam. She enjoyed an extensive career in oil and gas industry for thirty-three years with Mobil/ExxonMobil and is now retired in the mountains of Colorado. Susanne had the opportunity to move into management, but found that she missed the creativity and integration of widely varied geoscience and engineering data sets. So, she returned to reservoir development and management leading multidisciplinary teams to define reservoir architecture and 3D fluid flow characteristics. One of her highest achievements is receiving Mentor of the Year Award from ExxonMobil through mentoring younger members in science and engineering, and train them how to effectively work with multi-disciplinary/multi-national/multi-cultural team members.

Now that she is retired, she pursues many interests and volunteer opportunities - with her greatest joys being teaching. Her favorite volunteer work is teaching K-12 students just how much fun science and engineering are and showing them career paths that they may not have considered.

Susanne received her B.S. degree in Geology from Indiana University – Bloomington and her M.S. degree in Oceanography from TAMU.

The College of Geosciences Advisory Council is rooted in 1977 by Dean Dr. Earl Cook when Michel T. Halbouty donated $150,000 to establish the Geosciences and Earth Resources Endowment Fund (GERAC).  Concurrent to the endowment, the original Advisory Council, then called the Geosciences and Earth Resources Advisory Council was born.  The renowned group of industry leaders were passionate advocates and committed former students and friends to provide support and counsel to the Dean, faculty and staff of the College towards the achievement of high priorities, strategic initiatives, and achievements along the fulfillment of the College’s mission.  

Originally Chaired by Michel T. Halbouty ’30, the distinguished list of members included:

The original charge was threefold:  to advise the College of Geosciences on the changing needs of industry for well-trained geoscientists, so that the curricula and courses of the College will prepare our students to become productive professionals equal to or better than those from other schools; to advise on ways of obtaining financial and equipment support for programs of the College that cannot be adequately financed by either state appropriations or research contracts; and to advise on ways of fruitful cooperation between industry and the faculty and students of the College. 

The Geosciences and Earth Resources Advisory Council was also charged with the Michel T. Halbouty Medal selection process.

In September of 2007, the then-Dean of the College of Geosciences, Bjorn Kjerfve reestablished the Geosciences Advisory Council after a nine year hiatus when it had been Chaired by the late Michel T. Halbouty until 1998. 

The 2007 members were:  Bill Black, Conroe, TX; Carlos Dengo ’78, Geology; Richard Findley 73’ Geology; Dan Allen Hughes ’51, Geology; Tom Kelly ’53, Geology; and Les Shepard ’77, Oceanography.
