Low Resistivity, Low Contrast Pays

Instructor: John T. Kulha, Petrophysical/Petroleum Engineering Consultant

The fee includes refreshments, class notes, and PDH certificate

This course will provide a proven methodology to identify and evaluate low-resistivity, low-contrast (LRLC) pays as seen in modern wells or as potential bypassed pays in old wells. World-wide examples from productive LRLC reservoirs are presented. The following aspects of LRLC pays will be covered:

• Geologic causes and the depositional and diagenetic environments in which LRLC pays are commonly found.
• Identification and evaluation techniques using logs and samples.
• Quick-scan log techniques to identify possible productive sands.
• Examples of productive LRLC wells and reservoirs from many basins.
• Practical application of evaluation techniques on LRLC client workshop wells.

The first half of the workshop concentrates on general concepts and methodology to evaluate low-resistivity, low-contrast (LRLC) pays. The second half of the course is focused on examples. Participants are encouraged to bring non-proprietary examples that can be discussed in this session.

John Kulha has over 37 years experience in petrophysical and petroleum engineering studies related to exploration, development, reserve determination and property acquisition.His specialties include multi-well exploration, evaluation and development studies in complex lithologies and in shaly sands, log-seismic interrelationships, and unconventional resources including coalbed methane, tight gas, shale reservoirs, and heavy oil. John is a recognized authority in the identification and evaluation of low resistivity, low contrast (LRLC) pay zones and has presented seminars worldwide over the last 20 years. His education includes B.S. and M.S. degrees in Petroleum Engineering. He started his career with Shell Oil Company and has been in the consulting business since 1980.
