Data

These data are microanalyses of 91 polished thin sections that were examined using a scanning electron microscope (SEM) equipped with an energy dispersive spectrometer (EDS) to identify minerals and observe their relationships at high magnification. Samples are from the Triassic Chinle and Jurassic Morrison Formations and adjacent units, which are the main hosts for sandstone-hosted uranium-vanadi

This data release contains the boundaries of assessment units and input data for the assessment of undiscovered gas resources in the Lower Saxony Basin, Germany. The Assessment Unit is the fundamental unit used in the National Global Oil and Gas Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total P

This data release is a compilation of published and unpublished thermal maturity and source rock geochemical data (Rock-Eval, pyrolysis) from subsurface wells in the Permian Basin, west Texas and southeast New Mexico. These data include 67 newly collected samples and analyses from Delaware Basin wells (identified as Cicero_2022), as well as 1028 previously unpublished USGS analyses from the entire

The Candy Lane 1 (CL-1) core was acquired in November 2005 as part of a multidisciplinary effort by the U.S. Geological Survey, the Bureau of Land Management, and the Bureau of Reclamation to investigate the Mancos Shale in the Gunnison Gorge National Conservation Area, Montrose County, Colorado. The Upper Cretaceous Mancos core was taken from the NE 1/4 sec. 8, T. 50 N., R. 9 W. corresponding to

Hydraulic fracturing is a treatment method used to stimulate production from oil and gas wells. Hydraulic fracturing involves injection of treatment fluids mixed with propping agents under high pressure into perforated portions of the wellbore. This method causes the reservoir rocks to fracture and the hydraulic fracturing fluids and propping agents to enter the fractures. Subsequently, the inject

This data release contains the boundaries of assessment units, assessment input data and resulting fact sheet data tables for the assessment of undiscovered oil and gas resources in the Senegal Basin Province of northwest Africa. The Assessment Unit is the fundamental unit used in the National and Global Oil and Gas Assessment Project for the assessment of undiscovered oil and gas resources. The A

In 2006, Rock Well Petroleum drilled and logged nearly 1,600 feet (ft) of continuous core on the southern part of the Casper arch in Natrona County, Wyoming (see fig1.png). The core hole, named the Poison Spider core #8 penetrated the interval extending from the Upper Cretaceous Frontier Formation to the Triassic Alcova Limestone. The core was subsequently donated to the U.S. Geological Survey Cor

This data release provides 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- 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 binned
