Well Siting

GGI utilizes a variety of methods to optimize well locations in various geologic settings including basin fill, sedimentary bedrock, volcanic bedrock, and crystalline basement. Techniques employed include a combination of in-office research (review of published and unpublished data sources and proprietary internal data) and field work (geologic mapping, fracture analysis) to select drilling locations with the highest probability of good well production and water quality. Using these techniques, GGI has successfully recommended well locations throughout New Mexico and surrounding states.

Once the optimal well site has been selected, GGI examines the project water use needs and designs a well (Well Design) that will meet the project needs in the most cost-effective manner possible. Using this methodology, GGI has designed wells ranging in depth from less than 100 ft to over 3000 ft, with well production ranging from ±10 gallons per minute (gpm) to in excess of 4000 gpm, depending on the project needs.
