Over the past decade, the combination of horizontal drilling techniques and multi-stage hydraulic fracturing has led to a technological revolution in oil and gas development. It has given rise to a huge North American expansion of oil and gas development from unconventional (tight) resources. This rapid expansion has spurred evolution in industry practice, requiring a parallel development, or ...
Introduction Fracturing is an enhancement technology designed to increase the efficiency of other in situ technologies in difficult soil conditions. The fracturing extends and enlarges existing fissures and introduces new fractures, primarily in the horizontal direction. When fracturing has been completed, the formation is then subjected to vapor extraction, either by applying a vacuum to all ...
The recovery of natural gas and oil from untraditional wells is necessary for the economic stability of the United States. Shale gas deposits are deep below the earth’s surface and recovery of gas is expensive and requires millions of gallons of water mixed with chemicals, known as "fracking solution". Most fracking solution stays underground or returns to the surface mixed with formation ...
Natural gas plays a key role in our nation’s clean energy future. The United States has vast reserves of natural gas that are commercially viable as a result of advances in horizontal drilling and hydraulic fracturing technologies, which enable greater access to gas in rock formations deep underground. ...
Centralized treatment of wastewater is emerging as a viable solution for long-term efficiency in managing water sourcing and wastewater treatment in hydraulic fracturing. The number of hydraulic fracturing (fracking) shale oil and gas wells in the United States continues to increase. Within the Bakken Shale formation alone, in North Dakota and Montana, upwards of 15,000 hydraulic fracturing ...

Hydraulic fracturing or ‘Fracking’ has become more prevalent and controversial in the US in recent years. More than 90 percent of new wells in the US are completed using this method. While it is endorsed by some as a game-changer that promises an increase in the nation’s economy due to energy independence, job creation, and lower energy prices; others are calling for a temporary ...
The purpose of this document is to describe recent field demonstrations, commercial applications, and research on technologies that either treat soil and ground water in place or increase the solubility and mobility of contaminants to improve their removal by pump-and-treat remediation. It is hoped that this information will allow more regular consideration of new, less costly, and more effective ...
The Environmental Protection Agency is considering a rulemaking that might require chemical manufacturers and processors, as well as oil and gas exploration companies, to report on chemicals used in hydraulic fracturing. In an advance notice of proposed rulemaking, the EPA said it is seeking information from industries, state agencies and others on the range of data the agency should ...
“Water, water, everywhere, Nor any drop to drink.” –The Rime of the Ancient Mariner, Samuel Taylor Coleridge Many topics of conversation among oil and gas industry professionals are predictable – oil price trends, the “great shift change” imperiling the available workforce, and production quotas and caps from OPEC. Yet one pressing topic among those developing ...
The amount of water used in and produced by hydraulic fracturing of shale gas wells is in the millions of gallons per well. Whether the water is going to be taken off-site for disposal or reused for re-injection, the flowback or produced water needs pretreatment to remove any residual oil from the water. Waiting for remote laboratory results to determine the oil level can take several ...
Background The Global Petroleum Research Institute (GPRI) at Texas A&M University-College Station regularly conducts laboratory research studies on various oil and gas produced wastewaters with varying sample matrices. The GPRI tests samples at different shale and oil producing formations using a mobile laboratory, which houses a pilot-scale treatment system for identifying the ...
Ken Goldstein, CGWP moderated a session titled “High-Resolution Characterization in Fractured Rock” at the 2017 NGWA Conference on Fractured Rock and Groundwater, October 2-3 in Burlington, Vermont. Goldstein is senior vice president, water and environmental systems at Louis Berger. He recently shared his insights with us on fractured rock characterization and what he is looking ...
An integrated interpretation of field experimental cross-hole radar, tracer, and hydraulic data demonstrates the value of combining time-lapse geophysical monitoring with conventional hydrologic measurements for improved characterization of a fractured-rock aquifer. Time-lapse difference-attenuation radar tomography was conducted during saline tracer experiments at the US Geological Survey ...
The global hydraulic fracturing market is expected to reach USD 90.55 billion by 2020, according to a new study by Grand View Research, Inc. Regulatory support in the form of tax benefits and financial incentives, particularly in North America and Asia Pacific is expected to drive the global hydraulic fracturing market over the next six years. Depleting conventional oil & gas reserves has ...
This month, Enhesa US Regulatory Consultant, Rachel Degenhardt, was published on the issue of hydraulic fracturing and groundwater contamination in Berkeley’s Ecology Law Currents, an online publication of Ecology Law Quarterly, one of the nation’s most respected and widely read environmental law journals. “The U.S. EPA is working to increase transparency regarding the ...
Use of high‐volume hydraulic fracturing (HVHF) in unconventional reservoirs to recover previously inaccessible oil and natural gas is rapidly expanding in North America and elsewhere. Although hydraulic fracturing has been practiced for decades, the advent of more technologically advanced horizontal drilling coupled with improved slickwater chemical formulations has allowed extensive natural ...
Monitoring of hydraulic head is an important part of many hydrogeologic investigations because it is used to determine the rates and directions of ground-water flow. In unconfined aquifers, open-hole water levels can be used to establish meaningful conceptual models of ground-water flow. In heterogeneous fractured-rock aquifers, however, where the hydraulic head can be different for each fracture ...
