The PADEP provides eight primary reports on natural gas well activity to the public: Permits Issued, SPUD Data, Production Reports, Waste Reports, Compliance Reports, Public Utility Commission (PUC) Act 13 Unconventional Wells Spud Report, PADEP Oil & Gas Locations - Conventional Unconventional (hosted by PASDA), and Well Formations Report.Permits Issued – Proposed natural gas well drilling sites submitted to and approved by the PADEP.Spud Data – List of new natural gas wells drilled; the SPUD date refers to the date reported to DEP by the Operator that the drilling began (or will begin) at a well site.Production Reports – Information on natural gas production submitted by well operators. Conventional wells are submitted yearly while unconventional wells are submitted every six months (January to June and July to December) through the end of 2014. Starting in 2015, production is reported monthly. Waste Reports – Waste information from operators generated by drilling the well. Conventional wells are submitted yearly while unconventional wells are submitted every six months (January to June and July to December) through the end of 2014. Starting in 2015, Waste is reported monthly.Compliance Reports – Inspections of wells, including information on violations and fines.PUC Act 13 Unconventional Wells Spud Report – List of wells that the PADEP has identified that satisfy the requirements set by the Pennsylvania Act 13 Legislation.Oil & Gas Locations - Conventional Unconventional – Shapefile of the Oil & Gas Wells in Pennsylvania that the PADEP has locational information for broken into two formation types of conventional and unconventional wells.Well Formations Report – Displays geological formation information by listing the target, oldest and producing formations for all oil and gas wellsEach data source provides a well permit or API number for all wells, conventional and unconventional. By extracting well permits numbers from all eight data sources for any wells flagged by the PADEP as an unconventional well, a master table of permit numbers is generated of unconventional wells. By analyzing each data source, summary data is compiled to determine which wells are in the permitting process, are drilled, or are producing natural gas. Additional information includes how much gas is being produced, the number of violations, and which wells may be identified inconsistently as an unconventional well, as well as other attributes. The source data can be found at the following websites:Permit, SPUD, Compliance, Waste, Production, and Well Formation Reports: http://www.portal.state.pa.us/portal/server.pt/community/oil_and_gas_reports/20297Public Utility Commission (PUC) Act 13 Unconventional Wells Spud Report: http://www.portal.state.pa.us/portal/server.pt/community/act_13/20789PADEP Oil & Gas Locations - Conventional Unconventional: ftp://ftp.pasda.psu.edu/pub/pasda/dep/historic/OilGasLocations_ConventionalUnconventional/For more information on the project see https://maps.carnegiemnh.org/index.php/projects/unconventional-wells/

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.

This statistic shows the revenue of the industry “drilling oil and gas wells“ in Pennsylvania from 2012 to 2017, with a forecast to 2024. It is projected that the revenue of drilling oil and gas wells in Pennsylvania will amount to approximately ***** million U.S. Dollars by 2024.

This map displays the Carnegie Museum of Natural History Pennsylvania Unconventional Natural Gas Wells geodatabase to show the the life of unconventional wells throughout Pennsylvania.

A cells polygon feature class was created by the U. S. Geological Survey (USGS) to illustrate the degree of exploration, type of production, and distribution of production in the State of Pennsylvania. 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, or the type of production of the wells located within the cell is unknown or dry. Data were retrieved from the Pennsylvania Internet Record Imaging System (PA*IRIS). Cells were developed as a graphic solution to overcome the problem of displaying proprietary well data. No proprietary data are displayed or included in the cell maps. The data are current as of 2006.

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).

The following data set contains all the Oil & Gas Wells in Pennsylvania that the Dept of Enviromental 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 natureal 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. The following fields are displayed in the data set: PERMIT_NUM is the Permit Number associated with the well, WELL_NAME is the name given to the well by DEP or the Operator, OPERATOR the name of the current operator for the well, OPER_NUM is the Operator Number associated with the current operator, WELL_TYPE describes the type of well, WELL_TYPECD is the code associated with the Well type, WELL_STAT is the current status of the well, WELL_STATCD is the code associated with the current well status, PERM_DATE is the date associated with the permit number, SPUD_DATE is the drilling commencement date, or proposed drilling commencement date as reported by the operator, CONSV_IND indicates whether thie wellbore penetrates the Onondaga horizon as defined in the PA Oil & Gas Conservation Law, COUNTY is the county the well is permitted in, COUNTY_ID is the code associated to the county, MCD is the municipality that the well is in, MCD_TYPE is the type of municipality that the well is in, MCD_CD is the code associated to the municipality name, LATITUDE is the latitude of the well bore hole, LONGITUDE is the longitude of the well bore hole, PRMRY_FID is a system generated id associated with the primary facility record for this well in the DEP eFACTS database, UNCV_IND indicates whether this is a conventional or unconventional well, SURFACE_ELEV is the ground elevation at the well head location, WELL_CONFIG_CD indicates the well configuration, COAL_IND indicates if the well is in a coal or non coal region, PLUG_C_DATE is the well plug completion date, WELL_PAD is the name of the well pad on which the well is located.

As of 2020, Pennsylvania had an estimated ******* abandoned oil and gas wells, making it by far the U.S. state with the highest number of unused wells. In March 2020, there were *** drilled but uncompleted oil and gas wells in the Appalachia oilfield - which is partly located in Pennsylvania. Among the leading ten states with the highest number of abandoned oil and gas wells, Texas, Kansas, Illinois, and Louisiana were the ones with lowest numbers. Each one of these four states accounted with less than ************** abandoned oil and gas wells.

Individual well, individual operator (drilling company), individual municipality/county. Currently, the site contains data on approximately 150,000 oil and gas wells in Pennsylvania. By the end of summer, we expect to cover over 500,000 oil and gas wells in Pennsylvania, West Virginia and Ohio. Eventually, we hope to provide data on all oil and gas wells ever drilled in North Amerca - an estimated 4 million wells since the Drake well in 1859.

Oil/gas well integrity failures are a common but poorly constrained source of methane emissions to the atmosphere. As of 2014, Pennsylvania requires gas and oil well operators to report gas losses, both fugitive and process, from all active and unplugged abandoned gas and oil wells. We analyze 589,175 operator reports and find that lower-bound reported annual methane emissions averaged 22.1 Gg (−16.9, +19.5) between 2014 and 2018 from 62,483 wells, an average of only 47% of the statewide well inventory for those years. Extrapolating to the 2019 oil and gas well inventory yields well average emissions of 55.6 Gg CH4. These emissions are not currently included in the state’s oil and gas emission inventory. We also assess compliance in reporting among operators and note anomalies in reporting and apparent workarounds to reduce reported emissions. Suggestions for improving the accuracy and reliability in reporting and reducing emissions are offered.

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."

Brines having moderate to high salt content (up to 343 grams per liter [g/L]) occupy most pore spaces in rocks below a depth of a few thousand feet in Pennsylvania and are brought to the surface during oil and gas operations. Forty analyses of brines from a range of geologic environments in western Pennsylvania are reported here, accompanied by brief descriptions of analytical methods required to obtain valid and accuratedata, especially for unstable parameters such as pH and oxidation state. The brines are dominated by Na-Ca-Cl.

This map service displays present and past oil and gas production in the United States, as well as the location and intensity of exploratory drilling outside producing areas. To construct this map, digital data were used from more than 3 million wells in IHS Inc.'s PI/Dwights PLUS Well Data on CD-ROM, current through 10/1/2005. In some areas, the PI/Dwights data tend not to be complete, particularly for pre-1920 production. IHS data was supplemented with state wells databases for Indiana, Pennsylvania, Kentucky, Illinois, and Ohio, (current as of 2004 to 2006). Because of the proprietary nature of many of these databases, the area of the United States was divided into cells one quarter-mile square and the production information of each well is aggregated in each cell. No proprietary data are displayed or included in the cell maps. The cells are coded to represent whether the wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, or the type of production of the wells located within the cell is unknown or dry. The cell attributes also contain the latitude and longitude values of the center-cell coordinates.
