Jack Breig is an Associate with The Discovery Group and the Principal of Precision Petrophysics, LLC in Denver, Colorado, working primarily on resource evaluations and petrophysical models for the unconventional reservoirs.
His previous work assignments include: Chief Petrophysicist for Whiting Petroleum working DJ Basin, Williston Basin, Permian Basin, and various acquisitions and development projects around the U.S. He also worked as Petrophysical Consultant for Newfield Exploration Mid-continent, where the Woodford gas shale program was developed into a major shale gas resource, starting with a series of strange mudlog shows. Prior to this, he has worked as a petrophysicist for Schlumberger on International consulting projects, and in software design and development for Schlumberger-Geoquest. In my formative years in the industry, and as a senior development geologist/petrophysicist for Tenneco Oil -Rocky Mountain Division. At this time, the Williston Basin was mostly Mission Canyon, Duperow, and Red River carbonate stratigraphic traps, and the Bakken was the rarely productive, but fascinating, 4th objective. He worked and received my seminal training at Exxon Production Research in 1977-1980 as a development geologist/petrophysicist on Ghawar Field in Saudi Arabia, as part of the original Aramco consortium. Oh, to find a reservoir like that one again.
He received his B.S. degree in geology and biology from Brown University in 1973, and his M.S. degree in Earth and Planetary Science from the Stony Brook University (NY) in 1976, with a thesis on Carbonate Mud factories in modern reef environments.
