|
| | Geotechnical Exploration | Preliminary site reconnaissance and exploration to establish suitable conditions for construction of well-site infrastructure. |
| Well Siting | Determination of the optimum location of the well drilling infrastructure as related to the property available for drilling. |
| Permitting | Preparation and submittal of applicable permits to state agencies for gas well drilling and related activities. |
| Site Grading Design | Determination of cut and fill requirements for establishing the drilling pad and access roads as related to the site topography and establishment of fill compaction methods and standards. |
| Foundation and Roadway Design | Design of foundations for structures (e.g., compressor stations) and access roadways/stream crossings. |
| Impoundment Design | Design of impoundments, liners and hydraulic structures related to handling of fluids associated with drilling and hydraulic fracturing. In Pennsylvania, fresh or frac-water impoundment pits or dams at a well site must meet the requirements of PA Code, Chapter 78.56 to 78.63 and Chapter 105. |
| Undermining/Subsidence Potential | Identification of abandoned mines at drilling sites and evaluation of the potential effects of mine subsidence on well-site infrastructure. |
| Environmental Compliance | Monitoring of compliance with applicable environmental regulations. |
| Pipeline Layout | Planning and layout of pipelines for connection of wells to the local gas pipeline infrastructure. |
| Construction Monitoring | Monitoring of excavation, grading, and construction of drainage, impoundment structures and foundations related to site development. |
