Petroleum engineering capabilities include reserve estimations; production analysis and forecasting; log analysis; petroleum reservoir and aquifer characterizations; reservoir modeling; chemical optimization or completion operations, pressure transient analysis including rate transient analysis; and economic evaluations.

GGA has the ability to combine petroleum engineering with geology to streamline projects that require both disciplines. 

When representing clients before the Wyoming Oil and Gas Conservation Commission (WOGCC), we first prepare the application.  Then we manage the hearing preparation process by gathering, reviewing and analyzing evidence.  GGA maintains production databases for most producing formations within Wyoming; this streamlines drainage area and density exhibit prep for WOGCC hearings. We conclude by presenting testimony in a highly organized and coordinated manner lending significant credibility to our client’s position. GGA is proficient in both protested and unprotested cases before the WOGCC.

In addition to WOGCC hearings, we utilize engineering and geology to estimate resource reserves, evaluate infill drilling potential and assess mineral estates including reserves and economics.
