This point layer contains the approximate locations of all the Oil and Gas wells within Florida as of February 5, 2025. This layer was designed to provide the Oil and Gas Program with a graphical representation of historic Operational Permitted Oil Wells for planning and management purposes. An Excel table version of this dataset can be found at https://floridadep.gov/water/oil-gas/documents/oil-and-gas-permit-database.

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.

Collated by NPCA and FracTracker, this map shows the combined state-level data of orphan Oil and Gas wells. FracTracker Alliance and NPCA looked at state data on orphaned wells and discovered that there are 214,548 orphaned wells nationwide and 31,737 of them are within 30 miles of a national park site.An “orphaned” oil and gas well is a well that is not actively being used for authorized purposes, such as production, injection, or monitoring, and for which either no operator can be found, or the operator is unable to permanently plug the well and remediate and reclaim the well site. Federal, Tribal and state definitions vary for abandoned, idle and orphaned wells. Because there is not a uniformed way of tracking orphaned wells, estimates can range anywhere between thousands to millions of unidentified orphaned wells. FracTracker relied on information available at the state level to determine the number of orphaned wells using the best available data.This dataset was created as a snapshot in 2021 and has not been updated since.

The United States Documented Unplugged Orphaned Oil and Gas Well (DOW) dataset contains 117,672 wells in 27 states. The definition of an orphaned oil or gas well varies across data sources; the dataset includes oil or gas wells where the state indicates that the well is an unplugged orphan, or the following criteria are met: 1) no production for an average of 12 months (6 to 24 months depending on the state), 2) the well is unplugged, 3) there is no responsible party to manage the well for future re-use or for plugging and abandonment, and 4) the location of the well is documented. The dataset includes location coordinates, American Petroleum Institute (API) number, or other identification number, well type, well status, and additional information for each unplugged orphaned well. All data were collected by direct requests to the respective state agency overseeing oil and gas wells or data downloads from their online databases. Location format conversion was performed on wells without coordinate locations using tools provided by the Bureau of Land Management and some state agencies. No other data manipulations were performed to the source data aside from reformatting or the addition of explanatory notes.

This geographic information system combines detailed information and location coordinates for oil wells, gas wells, and pipelines from the Commission's files with base map data captured from U.S. Geological Survey 7.5 minute quadrangle maps. These interactive maps were developed using Environmental Systems Research Institute, Inc. (ESRI) ArcIMS software, and interface with the Commission's Production Data Query and Drilling Permit Query applications.

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 Illinois. 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 Illinois State Geological Survey (ISGS) oil and gas wells database. 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.

This digital dataset is comprised of two separate data files that contain total dissolved solids, well construction, and well identifying information for 1,131 petroleum wells used to map salinity in and around 31 southern and central California oil fields. Salinity mapping was done for 27 fields located in the southern San Joaquin Valley of Kern County (North Belridge, South Belridge, Canfield Ranch, North Coles Levee, South Coles Levee, Cymric, Edison, Elk Hills, Fruitvale, Greeley, Jasmin, Kern Bluff, Kern Front, Kern River, Lost Hills, Mount Poso, Mountain View, Poso Creek, Rio Bravo, Rosedale, Rosedale Ranch, Round Mountain, San Emidio Nose, Tejon, Ten Section, Wheeler Ridge, and Yowlumne), 3 fields in the Los Angeles (LA) Basin of Los Angeles County (Montebello, Santa Fe Springs, and Wilmington), and 1 field in the central coast area of Santa Barbara and San Luis Obispo Counties (Santa Maria Valley). Only petroleum wells that were located within the administrative boundaries ...

This dataset has results and the model associated with the publication Ciulla et al., (2024). It contains a U-Net semantic segmentation model (unet_model.h5) and associated code implemented in tensorflow 2.0 for the model training and identification of oil and gas well symbols in USGS historical topographic maps (HTMC). Given a quadrangle map (7.5 minutes), downloadable at this url: https://ngmdb.usgs.gov/topoview/, and a list of coordinates of the documented wells present in the area, the model returns the coordinates of oil and gas symbols in the HTMC maps. For reproducibility of our workflow, we provide a sample map in California and the documented well locations for the entire State of California (CalGEM_AllWells_20231128.csv) downloaded from https://www.conservation.ca.gov/calgem/maps/Pages/GISMapping2.aspx. Additionally, the locations of 1,301 potential undocumented orphaned wells identified using our deep learning framework or the counties of Los Angeles and Kern in California, and Osage and Oklahoma in Oklahoma are provided in the file found_potential_UOWs.zip. The results of the visual inspection of satellite imagery in Osage County is in the file visible_potential_UOWs.zip. The dataset also includes a custom tool to validate the detected symbols in the HTMC maps (vetting_tool.py). More details about the methodology can be found in the associated paper: Ciulla, F., Santos, A., Jordan, P., Kneafsey, T., Biraud, S.C., and Varadharajan, C. (2024) A Deep Learning Based Framework to Identify Undocumented Orphaned Oil and Gas Wells from Historical Maps: a Case Study for California and Oklahoma. Accepted for publication in Environmental Science and Technology. The geographical coordinates provided correspond to the locations of potential undocumented orphaned oil and gas wells (UOWs) extracted from historical maps. The actual presence of wells need to be confirmed with on-the-ground investigations. For your safety, do not attempt to visit or investigate these sites without appropriate safety training, proper equipment, and authorization from local authorities. Approaching these well sites without proper personal protective equipment (PPE) may pose significant health and safety risks. Oil and gas wells can emit hazardous gasses including methane, which is flammable, odorless and colorless, as well as hydrogen sulfide, which can be fatal even at low concentrations. Additionally, there may be unstable ground near the wellhead that may collapse around the wellbore. This dataset was prepared as an account of work sponsored by the United States Government.

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 are current as of April 2001.

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.

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.
