Robert 'Bob' Barba

Bob has over 40 years of practical experience in the petroleum industry as an openhole wireline engineer, product development manager, petrophysicist, and completion optimization advisor focusing on integrated reservoir characterization studies, completion optimization studies, rock mechanics analysis, and horizontal well field development projects. He has extensive experience in both conventional and organic shale reservoirs.

Bob received the Regional Formation Evaluation Award from the Society of Petroleum Engineers Southwest North America region (Permian Basin) in May of 2018. He served as a Distinguished Lecturer 1995-1996 for the Society of Petroleum Engineers on the optimization of completion designs using petrophysical and reservoir engineering inputs. Bob is a recognized industry authority on refracturing rock mechanics and practices. He delivered the keynote address at a major refracturing conference for the SPE in Calgary January 2016 and has delivered over 100 presentations on the use of refracturing to enhance production in organic shale reservoirs. Bob served as an expert witness on log derived rock properties for BP through Kirkland and Ellis in the Macondo trial. He pioneered techniques to evaluate well performance using production data and routine well log data and applied the concept to over 5,000 wells to date. This significantly improved completion results in those fields.

Most recent projects involve the application of these techniques in Permian organic shale reservoirs where a solid correlation between modeled propped height and production results enables operators to forward model production results from shale reservoirs. Bob has analyzed over 3,000 organic shale wells in the Permian Basin and 400 wells in the Eagle Ford to date.

Julia Smith Wellner is a marine geologist at the University of Houston.  Julia received her bachelor’s degree from Bryn Mawr College, her master’s degree from the University of Alabama, and her Ph.D. from Rice University in 2001.  Following her graduation from Rice, she worked for five years as a post-doctoral fellow and lecturer in the Department of Earth Science there.  She is now Research Assistant Professor in the Department of Earth and Atmospheric Sciences and Co-Director of the Geoscience Learning Center at the University of Houston.  Her primary research interest is in Antarctic glacial history and marine geology and she has completed six field seasons offshore Antarctica on the icebreaker RV/IB Nathaniel Palmer.  She also works in the Gulf of Mexico and Texas coast on projects related to coastal change and sediment budgets.

James J. Willis, PhD
James J. Willis, PhD

James J. Willis received his B.S. and M.S. degrees from the now University of Louisiana in 1989 and 1990, respectively, and his Ph.D. as a National Science Foundation fellow at Baylor University in 1993. From 1994-1996, he studied Planetary Geology as a NASA-funded postdoctoral fellow at Southern Methodist University. In 1996, he returned to UL, where he was awarded in 1997 the Hensarling-Chapman Endowed Professorship in Geology. In 2001, he left academia for industry consulting and teaching.

James has been the Editor and Publisher for the Lafayette Geological Society since 2002, and the Co-Editor/Managing Editor and Publisher for the Gulf Coast Association of Geological Societies since 2006. He’s received many grants and contracts, presented numerous talks, and published various papers on a diversity of geoscience topics. As an undergraduate, he developed a 4D quantitative well bore guidance theory, including the concept of positive versus negative thickness (sign indicating direction of drilling section), that predated availability of key real-time data—as an independent consultant and trainer for Baker Hughes for the last few years, it’s been particularly exciting to see just how far the reality of LWD technology has since advanced.

Lesli J. Wood, PhD
Lesli J. Wood, PhD

Dr. Wood joined the faculty at Colorado School of Mines in January 2015 as a Professor and the Robert Weimer Endowed Chair in Sedimentary and Petroleum Geology, where she is director of the Sedimentary Analogs Database and Research Program (SAnD). Prior to joining CSM, Dr. Wood held positions at the University of Texas at Austin, Amoco Production Company and Arco. She received her doctorate in 1992 from Colorado State University following her MS work at the University of Arkansas. Dr. Wood specializes in quantitative seismic geomorphology of clastic basins, structural and sedimentary system interactions, submarine mass failures, petroleum geology, mobile shales and geomorphology of Mars. She has served as SEPM Society for Sedimentary Geology national Secretary-Treasurer, the GCSSEPM President and is active in the Geological Society of America, the American Association of Petroleum Geologists and the Geological Society of Trinidad and Tobago. She also served as a member of the Ultra-Deepwater Advisory Committee for the U.S. Secretary of the Department of Energy and sits on the RPSEA Board of Directors and the RPSEA GECO2 advisory board. She serves as an Associate Editor at Geosphere and Interpretation. Dr. Wood has published widely on the nature of modern and ancient deep- to shallow-water systems around the world and has won numerous best paper and poster awards, including AAPG’s Sproule Award, and most recently the 2014 EAGE Norman Falcon Award as co-author of the Best Paper in Petroleum Geosciences. She, her wife and her pig are very pleased to be relocated back to the Rocky Mountains after 23 years in Texas.
