These well locations were derived from historical mine maps known as the WPA, Ksheet, and Hsheet collections. These locations are provided for informational purposes only and should not be sole means of decision making and are in no way a substitute for actual on the ground observation. In 1859, the United States’ first commercial oil well was drilled in Venango County, Pennsylvania. In the 150 years subsequent to this, an unknown number of oil and gas wells have been drilled in the state. A current estimate by the Independent Petroleum Association of America places that number at approximately 325,000. Of those 325,000 wells, over 200,000 are still unaccounted for. As these wells are found and verified, they are cataloged in the Department of Environmental Protection’s (DEP) Abandoned and Orphan Well database to facilitate plugging. There are currently over 8,200 wells listed in this database (2013). With so many unknown oil and gas wells scattered across Pennsylvania and the environmental threats that they pose, identification remains a vital component of DEP’s Oil and Gas Program. Currently, the DEP, Office of Active and Abandoned Mine Operations is involved in many projects dealing with historic and active mine map restoration and geo-referencing. These maps, which vary in age, not only contain information on historic mine locations, but also oil and gas locations. Through collaboration between the Bureau of Mining Programs and the Bureau of Oil and Gas Planning and Program Management, potential oil and gas well locations were assembled using three mine map collections. These collections include the WPA mine map collection, Ksheets collection, and the Hsheets collection. From these sources, over 30,000 potential historic oil and gas well locations were derived. The Bureau of Oil and Gas Planning and Program Management is constantly looking for historic sources to help locate oil and gas wells in the state that remain unaccounted for. This particular dataset was created using georeferenced mine maps of various/unknown accuracy and various/unknown coordinate systems to various base maps, including but not limited to USGS topographic maps and PAMAP aerial photography. The locations were then digitized using the georeferenced mine maps. These locations are provided for informational purposes only and should not be sole means of decision making and are in no way a substitute for actual field observations.

The following data set contains all the Oil & Gas Wells in Pennsylvania that the Dept of Environmental Protection has locational information on. The wells are broken into two formation types of conventional and unconventional wells. A conventional well is a bore hole drilled or being drilled for the purpose of or to be used for the production of oil or natural gas from only conventional formation(s). A conventional formation is any formation that does not meet the statutory definition of an unconventional formation. An unconventional gas well is a bore hole drilled or being drilled for the purpose of or to be used for the production of natural gas from an unconventional formation. Unconventional formation is a geological shale formation existing below the base of the Elk Sandstone or its geologic equivalent stratigraphic interval where natural gas generally cannot be produced at economic flow rates or in economic volumes except by vertical or horizontal well bores stimulated by hydraulic fracture treatments or by using multilateral well bores or other techniques to expose more of the formation to the well bore.

An Oil and Gas Location is a DEP primary facility type related to the Oil & Gas Program. The sub-facility types related to Oil and Gas that are included in this layer are:_ Land Application -- An area where drilling cuttings or waste are disposed by land application Well-- A well associated with oil and/or gas production Pit -- An approved pit that is used for storage of oil and gas well fluids . Some sub facility types are not included in this layer due to security policies.

From the site: "Cell maps for each oil and gas assessment unit were created by the USGS as a method for illustrating the degree of exploration, type of production, and distribution of production in an assessment unit or province. Each cell represents a quarter-mile square of the land surface, and the cells are coded to represent whether the wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, dry, or the type of production of the wells located within the cell is unknown. The well information was initially retrieved from the IHS Energy Group, PI/Dwights PLUS Well Data on CD-ROM, which is a proprietary, commercial database containing information for most oil and gas wells in the U.S. Cells were developed as a graphic solution to overcome the problem of displaying proprietary PI/Dwights PLUS Well Data. No proprietary data are displayed or included in the cell maps. The data from PI/Dwights PLUS Well Data were current as of October 2001 when the cell maps were created in 2002."

The data comprise the initial release of landscape disturbance polygons and lines (sites, pipelines and roads) related to natural gas and oil drilling developed prior to the end of 2013 in the 10-county region along the New York - Pennsylvania border. The study area includes the New York Counties of Allegany, Broome, Chemung, Steuben and Tioga, and the Pennsylvania counties of Bradford, McKean, Potter, Susquehanna, and Tioga. The data were collected using high-resolution aerial imagery from the National Agricultural Imagery Program (NAIP) for each available year between 2004 - 2013 within a geographic information system (GIS), along with additional geospatial data on oil and gas drilling permits and locations, administrative boundaries, ecoregions, and the footprint of the Marcellus Shale play. Data collection was a manual process of visually examining the NAIP imagery composite for each county for each year and using 2004 imagery as a baseline to identify and digitize landscape changes in the land cover resulting from the development of gas extraction infrastructure that occurred after 2004. Changes that correlated with natural gas extraction permits, appeared to be natural gas extraction related, or were in proximity to other gas extraction infrastructure were selected and digitized to the maximum extent of landscape disturbance. Disturbance that appeared in the 2004 imagery was collected; however, some of the collected disturbance for 2004 may predate the NAIP imagery collection date. The focus of the data collection was on features attributable to the construction, use, and maintenance of gas extraction drill sites, processing plants, and compressor stations, as well as the centerlines for new roads accessing such sites, plants, and stations, and the centerlines for new pipelines used to transport the extracted gas. Some of the roads and or pipelines may predate the data collection, however they appeared to be either expanded or worked on in relation to oil or gas activities in the study area. These data were collected within shapefiles by county, using ArcGIS 10.5. One shapefile was generated for sites (polygons), one was generated for roads (lines), and one was generated for pipelines (lines). Another team member reviewed the data for concurrence and consistency. These data identify disturbance related to natural gas and oil drilling, but do not identify the well types associated with that disturbance. For well type, see the New York Department of Environmental Conservation downloadable well data webpage (https://www.dec.ny.gov/energy/1603.html) or the Pennsylvania Department of Environmental Protection Oil and Gas Permit Database available at their web page (http://data-padep-1.opendata.arcgis.com/datasets?q=Oil%20&%20Gas).

DEP's Regional Offices are responsible for implementing department programs through permitting, inspection, enforcement, and other field services for environmental and public health protection; program and technical support to Pennsylvania's 66 conservation districts; and compliance assistance to our regulated community. In addition, staff in the regional offices provide assistance to the public in the form of emergency response, disaster recovery, pollution prevention, and energy assistance and complaint response.The regional offices directly implement the Air Quality, Environmental Cleanup and Brownfields, Radiation Protection, Waste Management, Watershed Conservation and Restoration, Clean Water, Waterways and Wetlands, and Safe Drinking Water Programs. Each regional field office is structured in the same manner to consistently implement these programs and services statewide. Additionally, the regional offices provide support services to the Active and Abandoned Mining Operations and Oil and Gas Management programs. In 2019, DEP launched the Regional Permit Coordination Office (RPCO). This move addressed a need to establish a centralized entity to provide Chapter 102/105 permitting functions for certain large and complex projects and to provide statewide technical support and coordination. Visit the RPCO website for more details.https://www.dep.pa.gov/About/Regional/Pages/default.aspx
