This data release contains several datasets that provide an overview of oil and gas well count, as well as oil, gas, water production, and water injection volumes in counties that overlap the Colorado River Basin in 2015 and 2019. Data are aggregated in 2-mile squares and are compiled from data from S&P Global, which is a commercially available database. No proprietary data is contained in this release.

Federal onshore lands contain an estimated 20 percent of the oil and 25 percent of the undiscovered natural gas resources in the United States (U.S. Bureau of Land Management, 2006) and the BLM has identified the Upper Colorado River Basin (UCRB) as an area with high potential for continued energy development (U.S. Bureau of Land Management, 2002). The UCRB drains portions of Arizona, Colorado, New Mexico, Utah, and Wyoming and is part of the largest river basin in the southwestern United States. A significant volume of known and potential oil and gas reserves lies in the sedimentary basins of the UCRB (Huffman, 1995; U.S. Geological Survey 2002a; U.S. Geological Survey 2002b; U.S. Geological Survey 2002c) and an average of 4,527 wells per year was started on Federal land in the five UCRB states in fiscal years (FY, October 1 to September 30) 2006 and 2007 (U.S. Bureau of Land Management 2008). An average of 2,462 wells per year were drilled between FY 2000 and 2005. 1,284 wells were drilled per year on average in the preceding 10 year period from FY 1990 to 1999. Increased drilling activity has raised concerns that land disturbance from drilling activity may have an affect on surface water quality in the basin. Existing and planned land disturbance data are not regularly or consistently compiled at the state or regional level. Regional-scale compilation, synthesis, and analysis of data defining energy development- related land disturbance and water quality in the UCRB may help to improve understanding of the potential cumulative effects of current and projected energy development on land cover changes in the basin. The location of known oil and gas wells was compiled from state oil and gas databases and merged into a single oil and gas well dataset for the UCRB. The reported status of each well was used to classify the well into two categories: disturbed or not disturbed. Disturbed wells are likely associated with land disturbance. The classified wells were used to estimate the location and extent of energy related land disturbance in the basin.

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 areas on active pads (not reclaimed areas or other features), and is likely an underestimate of the actual pad size in many areas. The remote sensing mapping methods may also capture areas of bright soils that are not part of a pad, especially in locations surrounded by very bright desert soils.

This data release contains several datasets that provide an overview of oil and gas well history and production of the United States, from 1817 to September 1, 2022. Well history data is aggregated into 1-mile and 10-mile squares indicating the total number of wells and counts of wells classified as oil, gas, dry, injection, hydraulically fractured, and/or horizontal wells. Well history is also separated into layers binned on 1-year increments from a well's spud date (date drilling commenced). Production data is aggregated in 2-mile and 10-mile squares that sum the total production of oil, gas, and water volumes. Production data is also separated into layers binned on 1-year increments to reflect the year of production. These aggregations are compiled from data from IHS Markit, which is a proprietary, commercial database. No proprietary data is contained in this release. This data release was updated May 2023 to reflect an offset of 1 year on the original release.

ESRI GRID raster datasets were created to display and quantify oil shale resources for eighteen zones in the Uinta Basin, Utah and Colorado as part of a 2010 National Oil Shale Assessment. The oil shale zones in descending order are: Bed 76, Bed 44, A Groove, Mahogany Zone, B Groove, R-6, L-5, R-5, L-4, R-4, L-3, R-3, L-2, R-2, L-1, R-1, L-0, and R-0. Each raster cell represents a one-acre square of the land surface and contains values for either oil yield in barrels per acre, gallons per ton, or isopach thickness, in feet, as defined by the grid name: *_b (barrels per acre), *_g (gallons per ton), and *_i (isopach thickness) where "*" can be replaced by the name of the oil shale zone.

The dataset includes detailed information on crude oil and natural gas production, including volumetric and descriptive data such as cumulative production, remaining reserves, and known recoverable volumes. Historical data covering field-discovery dates, well completion dates, exploration objectives, and well depths are also provided. Data sources include commercial databases along with supplemental information from various federal and state agencies. No proprietary data is included in this. The dataset is presented in multiple formats, including .pdf files for graphical images and .tab files for tabular data, encompassing eco-regional, federal land, ownership parcels, and state-wise data distributions.

This data release contains data associated with the USGS SIM publication "Stratigraphic Cross Sections of the Lewis Shale in the eastern part of the Southwestern Wyoming Province, Wyoming and Colorado". North-to-southeast (A–A’), west-to-east (B–B’), and southwest-to-northeast (C–C’) cross sections were created from 105 wells throughout the eastern part of the Southwestern Wyoming Province. The cross sections highlight 15 clinothems within the Lewis Shale, Fox Hills Sandstone, and Lance Formation progradational system. Data include well information and depths to key stratigraphic surfaces for 105 wells within the three cross sections. Well information includes the cross section identification, API #, well name, latitude in decimals, longitude in decimals, projection datum, county, state, Kelly Bushing elevation in feet, section, township, and range. Wells 19*, 26*, 69* and 70* are intersection points between the three sections. The stratigraphic data are all listed in measured depth relative to the Kelly bushing elevation and include the depth to the top of the Almond Formation, depth to the top and base of the informal Asquith marker, depth to the tops of 15 flooding surfaces which define the series of clinothems within the Lewis Shale, depth the top of the Lewis Shale, and depth to the top of the Fox Hills Sandstone.
