This dataset represents the Colorado Oil and Gas Conservation Commission's (COGCC) annual gas- and water-production data for oil and gas wells in the Raton Basin, Las Animas County, Colorado, during 1999-2004.

This digital geospatial data set consists of potentiometric contours that show lines of equal altitude of the generalized, long-term, regional water table in the northern part of Las Animas County, Colorado. The U.S. Geological Survey developed this data set as part of a cooperative project with the Colorado Water Conservation Board.

This dataset consists of reported depths to and calculated altitudes of selected geologic contacts, and calculated apparent thicknesses of selected hydrostratigraphic units, in the Raton Basin, Huerfano and Las Animas Counties, southeastern Colorado.

This digital geospatial data set consists of contours of lines of equal depth to the top of the Raton Formation, the contact between the Raton and Poison Canyon Formations, in Las Animas County, Colorado. The U.S. Geological Survey developed this data set as part of a cooperative project with the Colorado Water Conservation Board.

This dataset consists of water well locations, selected well-construction data, and hydrologic data, that are based on permit transactions submitted to the State Engineer Office, Division of Water Resources, Colorado Department of Natural Resources.

This U.S. Geological Survey (USGS) data release includes whole rock geochemical and isotopic data, and uranium-lead isotopic data collected by both Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) and Sensitive High Resolution Ion Microprobe-Reverse Geometry (SHRIMP-RG) methods for rocks in Colorado, Wyoming, Utah, and New Mexico.

The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board and Bureau of Land Management compiled and analyzed data for mapping groundwater salinity in selected oil and gas fields in California. The data for the South Cuyama oil field includes well construction data, digitized borehole geophysical data, geochemical analyses of water samples from oil and gas wells and groundwater wells, geological formation depths, and the groundwater total dissolved solids (TDS) calculations. These data have been compiled from many sources and span several decades. The well construction data includes attributes such as the date drilling began (spud date), borehole orientation, well depth (measured and true), and depth of top and bottom producing perforations. These data have been in archived scanned pages in raster format on the Division of Oil, Gas, and Geothermal Resources (DOGGR) website. Similarly, the borehole geophysical data, measured by oil companies, has been archived in raster format by DOGGR. This project has converted the borehole geophysical data from selected oil and gas wells into a computer readable numerical format. The geochemical analyses have also been archived in scanned formats, but now have been compiled into numerical datasets. Selected borehole geophysical and geochemical data collected from nearby monitoring, domestic, and supply wells publicly accessible through various USGS online sources are also included. The data compiled and analyzed are part of the California State Water Resources Control Board's Program of Regional Monitoring of Water Quality in Areas of Oil and Gas Production and the USGS California Oil, Gas, and Groundwater (COGG) program.
