My full curriculum vitae resides on LinkedIN.


"Over 20 years of practice as a reservoir engineering consultant and an operator, I studied scores of fields in depth, seeing all kinds of variety and variations in geology and dynamics.  My studies of shale fields began in the Barnett in 2003, but my experience also includes all manner of conventional fields, from simple depletion, to water-flooding to fractured carbonates."

"My wife, Katie, and I married nearly 17 years ago. We have two spunky daughters mostly grown and two adventurous sons in junior high and high school. As for me, in addition to the puzzles of reservoir engineering, I enjoy the outdoors, reading and writing."
