West Texas Wellsite

Koury Geosteering, LLC and West Texas Wellsite, Inc. have formed a strategic partnership to offer mudlogging and geosteering in tandem in Texas, Oklahoma, and New Mexico. Founded in 1985 by Mike Jerner, West Texas Wellsite, Inc. quickly gained a reputation for getting things done right the first time in the infamous Hardeman Basin in Texas, logging Chapel Dolomitic mud mounds (reefs) for Cimerex Energy, as well as many smaller independents. Often the difference between a producing or abandoned well was drilling a single foot. Mike went on to log more than 200 of these wells, many which were drilled horizontally in the Chapel formation.The lessons and skills learned in this demanding play permeate the company to this day and shaped its philosophy. Expanding on his early successes, West Texas Wellsite’s area of operations grew to include most major plays in Texas, Oklahoma, and New Mexico.
