Opportunities and Concerns in Using Produced Water
Produced water is natural groundwater that is extracted along with oil and gas. It is commonly salty and mixed with oil residues,1 so it must be either disposed of or treated and reused. About 2.5 billion gallons of produced water are extracted...

Introduction
The Arctic hosts large oil and natural gas resources both onshore and offshore.1 However, the harsh climate, extreme weather, remote locations, and limited infrastructure make exploration and production expensive and sometimes hazardous. In recent decades, decreased summer sea ice has...

Introduction
Methane is the main component of natural gas, a cheap, abundant, and versatile source of energy that produces less carbon dioxide than other fossil fuels when burned. However, methane itself is a more potent greenhouse gas than carbon dioxide. Methane leaks from wells, pipelines, or...

Introduction
In 2017, there were one million active oil and gas wells in the United States.1 When a well reaches the end of its productive life, or if it fails to find economic quantities of oil or gas, the well operator is required by regulators to remove all equipment and plug the well to...

Manmade Earthquakes
Any activity that significantly changes the pressure on or fluid content of rocks has the potential to trigger earthquakes. This includes geothermal energy production, water storage in large reservoirs, groundwater extraction, underground injection of water for enhanced oil...

Introduction
The Pinedale field is the sixth-largest gas field in the United States.1 The core development area covers about 70 square miles in a sparsely populated area of southwest Wyoming, 70-100 miles north of Rock Springs.2 In 2015, the Pinedale field produced 4 million barrels of gas...

Introduction
Oil and natural gas are complex mixtures of chemicals. Oil refineries and gas processing plants extract the organic compounds that make the best fuels for transportation, heating, and electricity generation: gasoline, jet fuel, diesel fuel, heating oil, and methane. Other chemicals...

Geologic Maps and Landslide Hazards
A geologic map is key to understanding landslide risk. The U.S. Geological Survey (USGS) and numerous state geological surveys around the nation prioritize the mapping of landslide-prone areas. Understanding landslide risk is crucial in making decisions around...

Using Geologic Maps to Protect Public Health
Geologic maps can be used to understand and mitigate public health risks across the US, in addition to their more traditional use in resource and infrastructure decisions. Geologic maps can show the location of naturally occurring hazardous materials...

Geologic Mapping
In 1992, Congress established the National Cooperative Geologic Mapping Program (NCGMP) in the U.S. Geological Survey to address the nationwide need for detailed geologic mapping. The NCGMP coordinates Federal, State, and academic programs to leverage all their mapping...
