Description: In the 150 years since the first oil well was drilled, an unknown number of oil and gas wells have been drilled in Pennsylvania. An estimate by Independent Petroleum Association of America places that number at approximately 325,000. DEP is aware of 2,900 Plugged wells, 8,000 Orphaned and Abandoned Wells and 111,000 permitted wells, which leaves over 200,000 wells unaccounted for. Many Oil and Gas wells are within close proximity to coal mining operations. DEP's Bureau of Mine Safety and Bureau of Oil and Gas PPM are in a joint endeavor to locate abandoned and orphaned wells in active mining areas. This will allow for proper plugging or avoidance prior to mining operations and prevent gas migration. This process included written correspondence to operators requesting Farm Line maps, which were then referenced in GIS to real world locations by using the following control points: roads, houses, water bodies and known coordinates. By using GIS, relative locations were determined and placed side by side with current ariel photography to determine plausible locations of unknown wells. The following attribute fields apply to the nearest plugged well, abandoned or orphaned well, spudded well and permitted well site to the farmline well:Plug_Dist_ft, Plug_Permit, A_O_Dist_ft, A_O_APInum, Spud_dist_ft, Spud_API, Permit_Dist_ft, Permit_API
