Utley Petrophysics

Utley Petrophysics offers a broad spectrum of advanced petrophysical and log analysis services. We bring to bear extensive experience, specializing in the unique challenges of limited wellbore data. We emphasize early integration of geological and engineering data to solve petrophysical problems and will accomplish your objectives within your time frame for any size project.

Our petrophysicists have successfully applied petrophysical technologies in a wide variety of locations, worldwide. Our experience with resistivity and SP modeling and neural network prediction of log and core properties is second to none. We make full use of Petroleum Software Technologies' software products, Rt-Mod, NNLAP, and SP-Mod.
