CWLS06SC Carbonate Petrophysics
- This three-day course is application-oriented, and designed for Petrophysicists, Engineers, Geologists and Team Leaders who are comfortable with integrated geology/routine & special core-log interpretation and require an understanding of the complexities of open-hole carbonate log analysis.
- The course begins with a contrast of carbonates and sandstones, followed by reservoir classification according to the Lucia Petrophysical Classification System and capillary pressure.
- Individual logging tools (both routine and specialty) are introduced and carbonate responses are illustrated with actual data.
- Archie’s exponents are discussed within the context of both his original measurements, and carbonate specific results.
- The concept of bulk volume water is introduced within the context of a Pickett Plot, and then related to Nuclear Magnetic Resonance and the combination of pore size and irreducible water saturation.
- Basic NMR, and carbonate specific NMR issues are introduced with laboratory measurements, numerical simulations and actual Wireline data.
- In addition to NMR and other non-Archie approaches, the course will address laboratory determination of mineralogy (XRD,etc), porosity and CT Scan visualization, which play important supporting roles in carbonate evaluation.
- You will learn to recognize the key distinctions between carbonates and sandstones within the context of modern Wireline measurements, and draw upon the strengths of specific tools/techniques to design a cross-discipline formation evaluation program that will best characterize a specific reservoir.

R.E. (Gene) Ballay’s 32 years in petrophysics include research and operations assignments in Houston (Shell Research), Texas; Anchorage (ARCO), Alaska; Dallas (ARCO Research), Texas; Jakarta (Huffco), Indonesia; Bakersfield (ARCO), California; and Dhahran, Saudi Arabia. His carbonate experience ranges from individual Niagaran reefs in Michigan to the Lisburne in Alaska to Ghawar, Saudi Arabia (the largest oilfield in the world).
He holds a PhD in Theoretical Physics with double minors in Electrical Engineering & Mathematics, has taught physics in two universities, mentored Nationals in Indonesia and Saudi Arabia, published numerous technical articles and been designated co-inventor on both American and European patents.
At retirement from the Saudi Arabian Oil Company he was the senior technical petrophysicist in the Reservoir Description Division and had represented petrophysics in three multi-discipline teams bringing on-line three (one clastic, two carbonate) multi-billion barrel increments. Subsequent to retirement from Saudi Aramco he established Robert E Ballay LLC, which provides physics – petrophysics consulting services.
He served in the US Army as a Microwave Repairman and in the US Navy as an Electronics Technician, and he is a USPA Parachutist and a PADI Dive Master.
