About Training
This five-day program introduces participants to established principles of carbonate sedimentology applied to hydrocarbon exploration and development geology.
The purpose of this seminar is to introduce participants to established principles of carbonate sedimentology, applied to hydrocarbon exploration and exploitation. Hydrocarbon play relationships associated with both shallow- and deep-marine sequences are emphasized, stressing the interrelationship between reservoir, source, seal and trapping mechanism. How one zones a carbonate reservoir to more effectively extract oil and gas is discussed as well.
Using a highly acclaimed, hands-on and rock-based approach, each participant learns to describe typical carbonate rocks, delineate facies and sequences, evaluate reservoir quality, relate carbonates to log and seismic expression, better predict play relationships in the subsurface, and construct a time-stratigraphic facies framework essential for both accurate regional correlation of carbonate sequences and zonation of carbonate reservoirs. Lectures are reinforced with exercises and problems keyed to identical sample rock sets, each containing 56 representative samples from around the world. A 750+ page notebook, with color copies of all power point slides shown in lectures, accompanies the course, as well as a reference book with pictures of samples used in various exercises. This seminar has been presented to industry over 100 times!
Training Objectives
- CLASSIFY AND IDENTIFY characteristics of a typical carbonate rock
- EVALUATE reservoir quality in limestones and dolostones
- INTERPRET facies relationships, delineate stratigraphic sequences and correlate facies within them
- IMPROVE UNDERSTANDING of hydrocarbon play relationships associated with both shallow – and deep-marine sequences
- UNDERSTAND the interrelationship between reservoir, source, seal and trapping mechanism
- LEARN how to zone carbonate reservoir to more effectively extract oil and gas
Audiences
This program is designed for exploration geologist, geophysicist, reservoir engineering, log analyst, exploration supervisors, and subsurface managers who are currently working or will be working with carbonate systems exploration, and are in need of a better understanding of the key subsurface properties for exploration and production. Geologists working with mixed carbonate and siliciclastic sequences will also benefit from this program.
Instructor
Jeffrey J. Dravis (Ph D)
Jeffrey Dravis is a carbonate geologist with 35 years of experience and owner of Dravis Geological Services, which conducts exploration and reservoir development projects in the U.S., Canada and overseas. He specializes in unravelling the controls on diagenesis and porosity evolution in carbonate sequences that aid in exploiting carbonate reservoirs. He applies innovative petrographic techniques to relate rock-based observations to well logs and seismic data, helping clients better define their subsurface plays and prospects. He has worked numerous carbonate projects in Africa, the Middle East, Southeast Asia and South America, as well as working Jurassic and Cretaceous sequences of the Gulf of Mexico, Devonian and Mississippian in western Canada, and Ordovician-Permian in west Texas and New Mexico. He has consulted for most of the large and smaller independent oil and gas companies in the U.S and Canada.
He is also the president of Dravis Interests, Inc., through which he conducts applied carbonate training seminars for the industry. Since 1987, he has presented well over 200 in-house and field carbonate seminars for industry clients, including over 65 field seminars on Caicos Platform in the southern Bahamas. He received his B.Sc. (geology) from St. Mary’s University in San Antonio, his M.Sc. (Marine Geology) from the University of Miami’s Rosenstiel School of Marine and Atmospheric Sciences, and a Ph.D. (geology) from Rice University, Houston. He worked for Exxon Production Research Company, in Houston, for eight years, before becoming a full-time consultant over 25 years ago. Since 1987, he has been an adjunct professor at Rice, where he teaches part-time and mentors students.
