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.

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 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 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.

South America is part of Region 6 (Central and South America) for the World Energy Assessment. South America was divided into 107 geologic provinces as background for prioritization and assessment of undiscovered oil and gas resources. The boundaries of geologic provinces are required for the assessment as oil and gas. Data must be allocated to a geographic entity so that decisions can be made as to which provinces are priority for the assessment. Many sources of geologic information were used to define the province boundaries in South America, and several versions of the map were reviewed. Of the 107 geologic provinces defined in South America, about 40 have had some oil and gas production to date.

The objective of this study is to enhance existing thermal maturity maps in Pennsylvania by establishing: 1) new subsurface CAI data points for the Ordovician and Devonian and 2) new %Ro and Rock Eval subsurface data points for Middle and Upper Devonian black shale units. Thermal maturity values for the Ordovician and Devonian strata are of major interest because they contain the source rocks for most of the oil and natural gas resources in the basin. Thermal maturity patterns of the Middle Ordovician Trenton Group are evaluated here because they closely approximate those of the overlying Ordovician Utica Shale that is believed to be the source rock for the regional oil and gas accumulation in Lower Silurian sandstones (Ryder and others, 1998) and for natural gas fields in fractured dolomite reservoirs of the Ordovician Black River-Trenton Limestones. Improved CAI-based thermal maturity maps of the Ordovician are important to identify areas of optimum gas generation from the Utica Shale and to provide constraints for interpreting the origin of oil and gas in the Lower Silurian regional accumulation and Ordovician Black River-Trenton fields. Thermal maturity maps of the Devonian will better constrain burial history-petroleum generation models of the Utica Shale, as well as place limitations on the origin of regional oil and gas accumulations in Upper Devonian sandstone and Middle to Upper Devonian black shale.

This data is visualized in the Michigan Orphan Wells Dashboard. Michigan’s Orphan Well Program was created in 1994. Orphan wells are abandoned or improperly plugged wells for which there is no known solvent existing owner or operator. EGLE’s Oil, Gas, and Minerals Division (OGMD) worked with the oil and gas industry for the passage of Act 308, P.A. 1994, which established an Orphan Well Fund within the Michigan Department of Treasury. OGMD utilizes the fund, paid for by revenue created by a severance tax on the oil and gas industry, to plug and remediate orphan well sites. Since the passage of Act 308 nearly 30 years ago, approximately 400 sites have either been plugged or remediated. As of October 1, 2022, Michigan had 447 documented orphan sites as well as additional associated orphaned facilities, piping, and contamination that remained to be addressed.Beginning October 1, 2022, OGMD began utilizing federal grant funds awarded under the Infrastructure Investment and Jobs Act (IIJA), 2021, also known as the Bipartisan Infrastructure Law Section 40601, to provide additional financial assistance for the Orphan Well Program. The IIJA created three types of grants for states to apply for to help address orphan wells and orphan facilities on federal, state, tribal, and private lands.This data also includes state funded orphan well cleanups. The orphan well data is updated nightly. A NULL in a field means that the field does not have any value.EGLE makes every attempt to ensure data accuracy but cannot guarantee the completeness or accuracy of the information contained within this dataset.
