This map shows the oil and natural gas wells across the United States. Oil and Natural Gas Well: A hole drilled in the earth for the purpose of finding or producing crude oil or natural gas; or producing services related to the production of crude or natural gas. Geographic coverage includes the United States (Alabama, Alaska, Arizona, Arkansas, California, Colorado, Florida, Illinois, Indiana, Kansas, Kentucky, Louisiana, Maryland, Michigan, Mississippi, Missouri, Montana, North Dakota, Nebraska, Nevada, New Mexico, New York, Ohio, Oklahoma, Oregon, Pennsylvania, South Dakota, Tennessee, Texas, Utah, Virginia, Washington, West Virginia, Wyoming) as well Oil and Natural Gas wells in the Canadian provinces of British Columbia and Manitoba that are within 100 miles of the country's border with the United States. According to the Energy Information Administration (EIA) the following states do not have active/producing Oil or Natural Gas Wells: Connecticut, Delaware, District of Columbia, Georgia, Hawaii, Iowa, Idaho, Massachusetts, Maine, Minnesota, North Carolina, New Hampshire, New Jersey, Rhode Island, South Carolina, Vermont, and Wisconsin. Some states do have wells for underground Natural Gas storage facilities where these have been identified they were included. This layer is derived from well data from individual states and provinces and United States Agencies. This layer is complete for the United States but further development of data missing from two Canadian provinces and Mexico is in process. This update release includes an additional 497,036 wells covering Texas. Oil and gas exploration in Texas takes advantage of drilling technology to use a single surface well drilling location to drill multiple bottom hole well connections to extract oil and gas. The addition of Well data from Texas results in the addition of a related table to support this one surface well to many bottom hole connections. This related table provides records for Wells that have more than one bottom hole linked to the surface well. Sourced from the HIFLD Open Data Portal for Energy.

The locations of wells that have been drilled for oil production, gas or salt resources or for underground storage of hydrocarbons.This data can be used for land use and resource management, emergency management, as well as compliance and enforcement in the petroleum industry. The Data is collected on an on-going basis and maintained in the Ontario Petroleum Data System (OPDS).

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 online map represents oil and gas wells in the CalGEM Well Statewide Tracking and Reporting System, or WellSTAR. Wells are displayed by well type and well status.

The California Department of Conservation, Division of Oil, Gas and Geothermal Resources publishes a GIS feature class of well locations across the state for use by the public. This shapefile is the same as the data displayed in the Division's WellFinder application (http://maps.conservation.ca.gov/doggr/index.html) as of July 6, 2016. This shapefile is provided in geographic coordinates on the North American Datum of 1983. A partial description of the attributes contained in this feature class is listed on the WellFinder application's Help system (see entity and attributes section in this metadata). Geothermal wells have been excluded from this shapefile.The DOGGR Wells layer in WellFinder is also available as a WFS service at http://spatialservices.conservation.ca.gov/arcgis/rest/services/DOMS/DOMS_Wells/MapServer/WFSServer?/.Well Attributes: API Number, Well Number, Well Status, GIS Symbol, Operator Code, Operator Name, Lease Name, Field Name, Area Name, District, County, Section, Township, Range, Base Meridian, Latitude, Longitude, Elevation, Total Depth, Redrill Footage, Redrill Cancel Flag, Location Description, Comments, GIS Source Code, Dry Hole, Confidential Well, Directionally Drilled, Hydraulically Fractured, BLM Well, EPA Well, Spud Date, Completion Date, Abandoned Date

This indicator provides information about the geographic locations of oil and gas wells. All records include operator name, field name, latitude, and longitude coordinates, well type, and well status.Oil and gas wells are located throughout Los Angeles County, including in residential areas. Living or working near oil and gas wells can lead to negative health effects. Additionally, oil and gas well activity can generate significant noise and vibrations in a community. Although Los Angeles County has approved a ban on all new oil and gas wells, with plans to phase out drilling over the next 20 years, potential hazards may remain. Regulation of existing oil and gas wells (both active and inactive) is critical to protecting public safety and the environment.For more information about the Community Health Profiles Data Initiative, please see the initiative homepage.

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.

This publication includes a booklet of data from all recorded oil, gas, helium, and geothermal wellsand from other deep wells. Two maps accompany the booklet. One is a map of the entire State that showsthe locations of wells tabulated in the booklet and of crude oil, gas, and product pipelines in Arizona. Areasin which wells are closely spaced are detailed on the second map.INFORMATION PROVIDEDThis list of 1,247 wells was printed from a database maintained by the Oil and Gas Administrator atthe Arizona Geological Survey. The list includes wells permitted by the Oil and Gas ConservationCommission since its inception in 1959, wells permitted by the State Land Department before 1959, andother wells for which information was obtained from various sources.The map is useful if you know the general geographic area in which a well is located but not itssection, township, or range. Once you have identified the section, township, and range on the map; searchfor the corresponding values in the booklet. The information in the booklet is only a portion of that which isavailable in the files of the Oil and Gas Program of the Arizona Geological Survey. These files includeinformation on every well listed, such as drilling records, electric logs, mud logs, and sample descriptions. Allthe files are public records and may be reviewed and copied in the Survey's office.The column titled 'SAMP 'contains an index number that identifies the box or boxes of samples orcore chips on file. Responsible parties may review these samples after making suitable arrangements withthe Oil and Gas Administrator.

This data release contains spatial data on the location, number, size and extent of energy-related surface disturbances on the Colorado Plateau of Utah, Colorado, and New Mexico as of 2016. The database includes: 1) polygons of oil and gas pads generated from automated and manual classification of aerial imagery, and 2) polylines of roads derived from the U.S. Census Bureau TIGER/Line Shapefile, supplemented with additional oil and gas access roads digitized from aerial imagery. Pad polygons and road segments are attributed with a "spud year" date based on spud information from the nearest well point. Spudding is the process of beginning to drill a well in the oil and gas industry, and the spud year is a close approximation of when the access roads and pads were cleared for development. The spud year information can be used to develop a chronology of oil and gas surface disturbances across the study region. The remote sensing-based pad mapping captures bright soil of disturbed are ...

The Oil and Gas Infrastructure Mapping (OGIM) database is a global, spatially explicit, and granular dataset of oil and gas infrastructure. It is developed by Environmental Defense Fund (EDF) (www.edf.org) and MethaneSAT, LLC (www.methanesat.org), a wholly owned subsidiary of EDF. The OGIM database helps fill a crucial geospatial data need, by supporting the quantification and source characterization of oil and gas methane emissions. The database is developed via acquisition, analysis, curation, integration, and quality-assurance (performed at EDF) of publicly available geospatial data sources. These oil and gas facility datasets are reported by governments, industry, academics, and other non-government entities.

OGIM is a collection of data tables within a GeoPackage. Each data table within the GeoPackage includes locations and facility attributes of oil and gas infrastructure types that are important sources of methane emissions, including: oil and gas production wells, offshore production platforms, natural gas compressor stations, oil and natural gas processing facilities, liquefied natural gas facilities, crude oil refineries, and pipelines. OGIM v2.7 includes approximately 6.7 million features, including 4.5 million point locations of oil and gas wells and over 1.2 million kilometers of oil and gas pipelines.

Please see the PDF document in the “Files” section of this page for more information about this version, including attribute column definitions, key changes since the previous version, and more. Full details on database development and related analytics can be found in the following Earth System Science Data (ESSD) journal paper.

Important note: While the results section of this manuscript is specific to v1 of the OGIM, the methods described therein are the same methods used to develop and update v2.7. Additionally, while we describe our data sources in detail in the manuscript above, and include maps of all acquired datasets, this open-access version of the OGIM database does not include the locations of about 300 natural gas compressor stations in Russia. Future updates may include these locations when appropriate permissions to make them publicly accessible are obtained.

OGIM v2.7 is based on public-domain datasets reported in February 2025 or prior. Each record in OGIM indicates a date (SRC_DATE) when the original source of the record was published or last updated. Some records may contain out-of-date information, for example, if a facility’s status has changed since we last visited a data source. We anticipate updating the OGIM database on a regular cadence and are continually including new public domain datasets as they become available.

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 of these 31 fields were used for salinity mapping. The dataset includes total dissolved solids (TDS) analyses from 1930 to 2015. TDS data for each well varies from a single analysis to multiple analyses for different sample dates and (or) collected from different depths within the same well. For wells having multiple analyses TDS represents the median value. There are 159 wells in the dataset each having 2-4 TDS analyses, including 15 wells having TDS values from different depths. This dataset also includes ancillary data in the form of top perforation depth, land-surface elevation at the well head, and well location and identifier information. For petroleum wells missing top perforation depth (3 percent), the median top perforation depth for all wells within the field having top of perforation depth is provided as an approximation for the purpose of vertical plotting. Summary data about each well used for salinity mapping is contained in the file called Petroleum_Wells_Summary_Data. Detailed information about all individual TDS values including those used for determining median TDS values, are contained in the file called Petroleum_Wells_All_Data.

Miscellaneous Publication 167, Map and database of exploration drilling targets categorized by play type, North Slope and offshore Arctic Alaska, presents a compilation of discovery well and production data for oil and gas wells throughout the North Slope and offshore Arctic Alaska. Since exploration drilling began on the North Slope of Alaska in 1944, numerous oil and gas accumulations have been discovered and 18 billion barrels of liquid hydrocarbons have been produced from North Alaska through 2018. Wells have targeted five main play types: Ellesmerian clastics and carbonates (Kekiktuk, Lisburne, Ivishak, Shublik, and Sag River), Jurassic shoreface sands (Barrow, Simpson, Kugrua, Nechelik, Nuiqsut, and Alpine), Cretaceous rift sands (Walakpa, Kuparuk, Put River, Kemik, and Thomson), Brookian turbidites (Torok, Seabee, and Canning), and Brookian topsets (Nanushuk, Tuluvak, Schrader Bluff, West Sak, Ugnu, Prince Creek, and Sagavanirktok). A sixth category called 'Other' includes the remaining targets (e.g., basement, methane hydrates, and coalbed methane). This comprehensive study documents the drilling target by play type from public domain sources for 548 exploration wells on the North Slope and adjacent offshore areas in the Beaufort Sea and Chukchi Sea. The discovery well and production data for each producing pool are integrated into the study. All files are available from the DGGS website: http://doi.org/10.14509/30579.

There are 487 onshore oil and gas fields in California encompassing 3,392 square miles of aggregated area. The California State Water Resources Control Board (State Water Board) initiated a Regional Monitoring Program (RMP) in July 2015, intended to determine where and to what degree groundwater quality may be at potential risk to contamination related to oil and gas development activities including well stimulation, well integrity issues, produced water ponds, and underground injection. The first step in monitoring groundwater in and near oil and gas fields is to prioritize the 487 fields using consistent statewide analysis of available data that indicate potential risk of groundwater to oil and gas development. There were limited existing data on potential groundwater risk factors available for oil and gas fields across the state. During 2014-2016, the U.S. Geological Survey (USGS) extracted and compiled data from various sources, including the California Division of Oil, Gas, and Geothermal Resources (DOGGR) and the Department of Water Resources (DWR). Geospatial data from the DOGGR were used in the prioritization analysis. Dataset include geospatial data for 222,637 petroleum wells, administrative boundaries for 514 oil, gas, and geothermal fields, and boundaries for DOGGR's 6 juristictional districts. The data were downloaded from DOGGR's Geographic Information System (GIS) Mapping website at http://www.conservation.ca.gov/dog/maps. The DOGGR GIS Mapping website is periodally updated, and the datasets downloaded by the U.S. Geological Survey in 2014 may no longer be available on the DOGGR website.
