PETROLEUM GEOLOGY

Our staff has a combined experience of over 40 years in geological oil and gas exploration and production.  This experience ranges from management positions to prospect generation, economic analysis, project financing, evaluation, and review, well-site geological supervision and log analysis.
Our geologic staff possesses in-depth knowledge in clastic stratigraphy with areal experience covering the entire northern Rockies.  GGA is capable of prospecting, land acquisition program design, reservoir characterization, reserve analysis, deal creation and financing, and economic evaluation.  The firm has experience in evaluations for producing property acquisition or divestiture, estate evaluations and Internal Revenue evaluations.

PETROLEUM ENGINEERING

Reservoir engineering capabilities include reserves estimation, production analysis and forecasting, log analysis, aquifer/reservoir characterization, reservoir modeling, pressure transient analysis including reciprocal productivity index analysis, and economic evaluation.
GGA's combined engineering and geologic capabilities streamline exploration/development projects that require both areas of expertise.  Projects include coal bed methane reserves estimation in the Powder River Basin, infill drilling evaluations for tight gas sands in the Lance and Mesaverde Formations of southern and western Wyoming, estate mineral evaluations including reserves and economics, and drilling and spacing hearings before the Wyoming Oil & Gas Conservation Commission.  

WATER

Surface Water -- Our staff has knowledge of Water Management Plans for BLM and National Pollution Discharge Elimination System (NPDES and in Wyoming WYPDES) permit applications for WDEQ. Water management Plans are exclusive to Coal Bed Natural Gas activities but WYPDES permits are required for any surface discharge relative to the energy industry. Preparation of Use Attainability Analyses (UAA) by GGA has resulted in successful petitions to the Wyoming Division of Water Quality for site-specific surface water quality discharge limits and reclassification of discharge streams to meet more appropriate surface water quality standards. GGA also has the legal ability to review State Engineer Office records to determine surface water rights.

Groundwater -- GGA's experience includes preparation of Underground Injection Control (UIC) permit applications for both Class I Commercial wells (WDEQ) and Class II Oil and Gas produced water wells (Wyoming Oil and Gas Conservation Commission). Aquifer characterization, pump testing and analysis and groundwater flow modeling are part of GGA expertise.  GGA has the legal the capability to review State Engineer Office records to determine groundwater water rights.

REGULATORY COMPLIANCE

Oil & Gas Phase I Site Assessments -- GGA has in-depth experience in conducting baseline Phase I Site Assessments prior to acquisition or divestiture of oil and gas producing properties.  GGA’ staff has completed the ASTM school for Commercial Real Estate Transactions and follows the general ASTM guidelines (E 1527-97).  The combined knowledge of regulatory requirements and production operations provides a unique expertise benefiting the client. 

 Oil & Gas Regulatory Compliance -- GGA has experience in self-owned oil and gas operations and field supervision.  Our staff can complete an assessment of the operations and determine the Federal and State programs that must be in place to achieve regulatory compliance.  GGA has generated Hazard Communication Plans (Hazcom), SARA Title III initial and annual reports and reporting procedures and Spill Reporting procedures and forms.  GGA is familiar with Bureau of Land Management (BLM) and Wyoming Oil and Gas Conservation Commission rules and regulations for oil and gas field operations in Wyoming.  GGA has in depth experience in the Wyoming State Engineer's office researching and listing surface and ground water rights.

Use Attainability Analyses (UAA) for Oil Production NPDES Discharge Permit Renewals to successfully petition the Wyoming Environmental Quality Council for site-specific surface water quality discharge permit limits and to re-classify discharge streams to meet more appropriate less stringent surface water quality standards.

NATIONAL ENVIRONMENTAL POLICY ACT (NEPA)

GGA’s staff has served as coordinator for many NEPA documents both at lead and as individual company representatives.  GGA personnel offer in-depth qualifications in areas of industrial permit coordination, geologic studies and NEPA documents.  GGA's staff has specific experience in surface and ground water rights.  GGA maintains a multidisciplinary network of other resource and research specialists from every field required to provide environmental impact statements, permit applications and management services.
