Geologists working at Goolsby Brothers and Associates, Inc., have many decades of wellsite supervision experience throughout the U.S. Our expertise includes vertical, directional, and horizontal wellsite supervision. We use computer-based horizontal and vertical strip log software programs from Wellsite Systems of Calgary, Alberta. Our geologists provide superior expertise in sample examination, show evaluation, drillstem test supervision, and geophysical log analysis. We've supervised wells from California to West Virgina, and from Canada to Texas. Whether you are trying to hit a reservoir target in a structurally complex area or keep a horizontal well in a ten foot zone for a mile, we are your best choice for wellsite supervision.

An example of a horizontal well strip log produced by Goolsby Brothers and Associates, Inc.  During our geological wellsite supervision of horizontal wells, we dictate the best target line to the wellsite personnel during drilling  operations.   We've successfully kept the bit in dolomite reservoirs that are less than 10 feet thick for distances of more than 6000 feet.  Strip logs are built in "real time", and updated continually with each new survey.  We've supervised many horizontal and directional wells during "geosteering" operations in many different basins.  Of course, our supervision of vertical  wells is carried out in a similar conscientious manner.
