Uses of Core Analysis

BY Eric Withjack, PTS Laboratories Inc.


Do you think that “core analysis” is looking through a microscope to see the rock grains, or measuring a capillary pressure curve, or relative permeability curve? Or is it an extra-cost activity that you sometimes commit to by taking core from a new well in hopes of gaining some additional information, or perhaps to have some “real” rock stored-away in case there may be a need for it in the future. Hopefully, I’ve stirred some thoughts about where a talk on Uses of Core Analysis is “going”. Each one of us probably has our own perspective on uses of core analysis from years of experience, which may be focused on conventional core analysis or project-specific individual tests. The purpose of my talk is to expand the scope of your understanding of core analysis beyond data collection/reporting, and present a more all-encompassing picture of its use on a reservoir scale. At this level, the value of core analysis can be fully realized. The main objective of my talk is to provide a more comprehensive understanding of the uses of core analysis, and illustrate by examples how it can impact reservoir value.



Eric is the Vice President of Technology for PTS Laboratories, Inc. In this position he provides corporate-wide technical leadership in core analysis methods based upon 30 years of experience in the upstream oil and gas industry. Eric’s experiences include Cities Service Oil and Gas, ARCO Oil and Gas, and UNOCAL Corporation, performing reservoir engineering and simulation, core analysis, and laboratory studies to optimize oil recovery. At ARCO, Eric was a pioneer in the application of x-ray computed Tomography (CT) for the oil industry, making a significant new step forward in understanding rock fabric and how to improve oil extraction in reservoir rock. Eric worked for Baker Atlas/Geoscience (Houston) developing new technologies and integrating cross-well seismic data with reservoir characterization. Upon returning to So Cal and prior to joining PTS, he performed consulting for Plains Resources, and reservoir engineering for Breitburn Energy.

Eric holds a B.S. from Norwich Univ., an M.S. from Syracuse Univ., and a Ph.D. from Rutgers (Mechanical and Aerospace Engineering). He is active in the Society of Petroleum Engineers (LABSPE Board, and SPE RE&E Technical Editor), and also serves as a California Regional Director for the Society of Core Analysts.
