Prospect Evaluation

We specialize in the evaluation of wildcat and development drilling opportunities. Our abilities to assess geological risk for oil and gas exploration extends to complex stratigraphic and structural settings. Goolsby Brothers and Associate, Inc., has experience in complicated plays types, including areas of hydrodynamic influence or in pervasively-saturated locations. We’re familiar with both carbonate and clastic reservoirs found in a variety of depositional settings, and have evaluated plays developed in fractured, vuggy, shaly, thin-bedded, and other complicated pore systems. We enjoy working with by-passed pay potential, and specialize in assessing formation damage possibilities. Please consider Goolsby Brothers and Associates, Inc., the next time you need an appraisal of the geological risk associated with the deal you are evaluating.

shaly ss log example

An example of log analysis in a thin-bedded shaly sandstone reservoir. The top of the pay zone is at 7282 ft. Calibration to core analysis is shown in tracks three, four, and seven, including calibration to flushed and residual hydrocarbons in track three. Track five shows a couple of different quick-look analysis techniques. Notice the neural-network generated synthetic Winland R-35 pore throat diameter in track seven. This synthetic pore-throat diameter, calibrated to core analysis in several wells, resulted in the recognition that the zone at 7260 ft was contributing most of the water to production when these wells were fracture stimulated. Our abilities to evaluate pay potential in such complicated settings gives Goolsby Brothers and Associates, Inc., great flexibility in evaluating geological risk in a variety of exploration and development settings.
