Carbonate petrophysics begins with a contrast of carbonates and sandstones, followed by reservoir classification according to the Lucia Petrophysical Classification methodology. Thin sections and CT-Scans are used for visualization while capillary pressure serves to quantify the differing properties. Individual logging tools (both routine and specialty) are introduced; carbonate responses are illustrated with actual data. Archie’s exponents are discussed within the context of both his original data sets, and carbonate specific measurements. The complementary attributes of each tool and technique are used to identify and evaluate complex carbonate reservoirs, as illustrated with actual applications.
Recognize the key distinctions between carbonates and sandstones, and understand the implications of those differences upon modern logging tool responses and formation evaluation methods
Perform both quick-look and detailed interpretations, taking into account carbonate complexities
Design a cross-discipline formation evaluation program that will characterize the interpretational parameters associated with a specific reservoir, and facilitate complete analyses
Dr. R. E. (Gene) Ballay is a consulting petrophysicist with 28 years of hands-on domestic – international / operations – research experience, including assignments in Houston (TX), Anchorage (AK), Dallas (TX), Jakarta (Indonesia), Bakersfield (CA) and Dhahran (Saudi Arabia). At retirement from the Saudi Arabian Oil Company, he was the senior technical petrophysicist in the Reservoir Description Division. He holds a PhD in Theoretical Physics with double minors in Electrical Engineering & Mathematics from Iowa State University, has taught physics in two universities, published numerous technical articles and been designated co-inventor on both American and European patents. He also served as a Microwave Repairman in the US Army and as an Electronics Technician in the US Navy, and is a USPA Parachutist and a PADI Dive Master.
