Spatial and Temporal Data on Hydraulic Fracturing Fluid Types and Amounts Injected into Oil and Gas Wells Across the U.S., 2015-2019
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
Natural Gas Compositional Analyses Dataset of Gases from United States Wells
This dataset was created to document the natural occurrence of helium and carbon dioxide throughout the United States. This dataset is sourced primarily from publicly available data from the Bureau of Land Management (BLM) Federal Helium Program and the U.S. Geological Survey (USGS). The Federal Helium Program, which originally began in 1925 under the U.S. Bureau of Mines (USBM) has analyzed thous
Dataset of Helium Concentrations in United States Wells
This dataset provides national scale location information for known, publicly available, data on helium gas concentrations, reported in mol%. The dataset was created as part of the effort by the United States Geological Survey (USGS) to conduct an assessment of helium resources in accordance with the Helium Stewardship Act of 2013, Public Law 113-40. The data were collected from the USGS Energy Ge
Data to Estimate Water Use Associated with Continuous Oil and Gas Development, Permian Basin, United States, 1980-2019.
One of the largest conventional oil reservoirs in the United States, the Permian Basin, is becoming one of the world?s largest continuous oil and gas producing reservoirs. Continuous, or horizontal well drilling techniques extract oil and gas by directionally drilling and hydraulically fracturing the surrounding reservoir rock. The continuous extraction of oil and gas using hydraulic fracturing re

Water used for hydraulic fracturing treatments in and near the Williston Basin during 2000-2015, was estimated using data reported in IHS Markit (TM) (2016). Hydraulic fracturing treatment data from IHS Markit (TM) (2016) may include volumes in a variety of measurement units, and they may include multiple treatments per well. All listed treatments within the study area were converted to gallons an

How quickly do oil and gas wells “Water Out”? Quantifying and contrasting water production trends
Water production from petroleum (oil and natural gas) wells is a topic of increasing environmental and economic importance, yet quantification efforts have been limited to date, and patterns between and within petroleum plays are largely unscrutinized. Additionally, classification of reservoirs as “unconventional” (also known as “continuous”) carries scientific and regulatory importance, but in so

Examining water and proppant demand, and produced water production, associated with petroleum resource development in the Eagle Ford Group, Texas
More than 20,000 horizontal wells have been drilled and hydraulically fractured in the Eagle Ford Group since the discovery well in 2008, but a considerable amount of undiscovered petroleum remains. Recently, drilled wells have been hydraulically fractured with an average of nearly 13 million gallons of water and 16 million lb of sand, yielding a million or more gallons of produced water.

National assessment of carbon dioxide enhanced oil recovery and associated carbon dioxide retention resources — Results
In 2020, the U.S. Geological Survey (USGS) completed a probabilistic assessment of the volume of technically recoverable oil resources available if current carbon dioxide enhanced oil recovery (CO2-EOR) technologies were applied to amenable oil reservoirs underlying the onshore and State waters areas of the conterminous United States.
