Case Studies & Factsheets

Cover of Heavy Oil

Introduction Naturally occurring crude oil comes in many forms. The most familiar to many people is light crude oil, which is less dense than water and flows easily at room temperature. Heavy oil and bitumen are forms of crude oil that are more viscous (thicker) and dense. The largest crude oil...

Cover of Water Sources for Hydraulic Fracturing

Hydraulic Fracturing and Water Demand Hydraulically fracturing a modern well can require millions of gallons of water for the initial fracturing process. This is a potential problem in arid regions with competing demands for fresh water (i.e. high water stress), such as Colorado and West Texas (...

Cover of Water in the Oil and Gas Industry

Introduction The oil and gas industry consumes and produces water. Water is used to drill and hydraulically fracture (“frack”) wells, refine and process oil and gas, and produce electricity in some natural gas power plants. Water is also naturally present in the rocks that contain oil and gas...

CI_CaseStudy_2017_2_MAR_170925_thumb.JPG

The Need for Groundwater Management: Sustaining water supplies and preventing hazards In California, surface water from rainfall, snowmelt, and distant rivers rarely meets the state’s urban and agricultural water needs. Groundwater is an essential water source, providing 35% of the fresh water...

Cover of The Pinedale Gas Field, Wyoming

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...

Cover of Groundwater Protection in Oil and Gas Production

Introduction The United States relies on groundwater for roughly 25% of its fresh water.1 This groundwater is found in porous, permeable rocks (aquifers) that often lie close to the Earth’s surface – the deepest freshwater aquifers are found more than 6,000 feet underground,2 but most are much...

Cover of U.S. Regulation of Oil and Gas Operations

Overview Regulation of oil and gas operations has existed in various forms for over 100 years.1 Regulation has several objectives: protecting the environment (including air and water quality), protecting cultural resources, protecting workers’ and the public’s health and safety, and reducing...

CI_Factsheet_2017_4_drywellbasics_170906_thumb.JPG

What is a Dry Well? A dry well is a well that is used to transmit surface water underground and is deeper than its width at the surface (see image, below). Most dry wells are 30 to 70 feet deep and 3 feet wide at the surface. They are lined with perforated casings and can be filled with gravel...

Cover of Offshore Oil and Gas

Introduction Many of the world’s oil and gas resources lie beneath the oceans. Advances in exploration, drilling, and production technologies allow production in water more than 10,000 feet deep and more than 100 miles offshore. Major spills are rare but damage sensitive ocean and coastal...

CI_Factsheet_2017_5_drywellprograms_170906_thumb.JPG

Introduction Dry wells improve stormwater drainage and aquifer recharge by providing a fast, direct route for rainwater to drain deep into underlying sediment and rock. Dry wells are most common in the western U.S. where clay or caliche layers slow down the natural drainage of water into...

CI_Factsheet_2017_6_MAR_170921_thumb.JPG

Why water storage? A reliable water supply is essential for economic, environmental, and public health, but natural water supplies vary with the seasons and between years. Water storage, whether in reservoir lakes or underground, helps to ensure that water is available even during droughts....

Defining the Problem The population of the historic village of Placitas, New Mexico, in the picturesque and geologically complex Sandia foothills north of Albuquerque, has tripled since 1970. Increased domestic well development, combined with persistent droughts, have culminated in dry and...

Cover of Spills in Oil and Natural Gas Fields

Introduction Oilfield spills can harm wildlife and pose a risk to human health if they reach fresh water sources or contaminate soil or air. The enormous size of the oil and gas industry and the huge volumes of oil and produced water that are handled, stored, and transported result in thousands...

Defining the Problem In central Alabama, the Mississippian-age Fort Payne Chert is an important aquifer for domestic and municipal water supplies. Rainfall recharges groundwater where the chert is exposed at the land surface. Where the chert has been quarried, many of the abandoned pits have...

Cover of Geoscientists in Petroleum and the Environment

Introduction Geoscience – the study of the Earth – underpins our understanding of the many intersections between petroleum and the environment, from the search for resources to the study of air pollutants. Without the work of geoscientists, we would have neither the energy system nor the...

CI_Factsheet_2017_2_groundwater_170309_thumb.JPG

Fresh water from underground Groundwater is any water found underground in the cracks and pores in soil, sand, or rock. Groundwater provides 25% of the fresh water used in the United States.1 It is particularly important for irrigation and domestic uses in arid or remote areas, where surface...

Cover of Abandoned Wells

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...

Cover of Using Produced Water

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...

Course Type: Webinar

A groundwater well is a lifeline for many people and communities. It will provide drinking water for decades, if it is properly maintained. Just like your teeth need to be cleaned by the dentist and the oil in your car's engine needs to be changed to maintain a long and healthy life, so does...

Course Type: Webinar

Depending upon how you have maintained your well, the costs for re-development will vary. For example, for a well that has not been maintained, the costs and methods for re-development can be very high. For well-maintained wells, re-development costs should be less. Remember that part of the re-...
