Hydraulic fracturing proppants and List of additives for hydraulic fracturing The main purposes of fracturing fluid are to extend fractures, add lubrication, change gel strength, and to carry proppant into the formation. High-viscosity fracturing tends to cause large dominant fractures, while high-rate slickwater fracturing causes small spread-out micro-fractures. Types of proppant include silica sandresin-coated sand, bauxiteand man-made ceramics. The choice of proppant depends on the type of permeability or grain strength needed.
Road salt good for winter driving, bad for wells December 26, HealthDay —The salt that makes icy roads safe in winter may not be so good for your drinking water, researchers report.
How much water does US fracking really use?
September 15, Energy companies used nearly billion gallons of water to extract unconventional shale gas and oil from hydraulically fractured wells in the United States between anda new Duke University study finds. Fracking plays active role in generating toxic metal wastewater, study finds December 15, The production of hazardous wastewater in hydraulic fracturing is assumed to be partly due to chemicals introduced into injected freshwater when it mixes with highly saline brine naturally present in the rock.
New contaminants found in oil and gas wastewater January 14, Duke University scientists have discovered high levels of two potentially hazardous contaminants, ammonium and iodide, in wastewater being discharged or spilled into streams and rivers from oil and gas operations in Pennsylvania Does living near an oil or natural gas well affect your drinking water?
February 14, "The answer to that question is usually 'no,' but there are exceptions," said Stanford Professor Rob Jackson, a professor of Earth system science at Stanford University, and a senior fellow at the Stanford Woods Institute Recommended for you Huge quake edges New Zealand islands closer together November 24, A destructive earthquake that struck New Zealand two years ago has left its two main islands edging towards each other, and one city sinking, according to scientists.
Greenhouse gas levels in atmosphere hit new high: UN November 22, The levels of greenhouse gases in the atmosphere, the main driver of climate change, have hit a new record high, the UN said Thursday, warning that the time to act was running out.
Oil giant Chevron recycles 21 million gallons of that water each day and sells it to farmers who use it on about 45, acres of crops, about 10% of Kern County's farmland. EPA released the final report for the study of fracking's impact on drinking water in December Here you can find a summary of the report, the full report, some . FracFocus is a hydraulic fracturing chemical registry website designed to provide information about chemicals used in the HF of oil and gas wells.
Researchers measure carbon footprint of Canada hydroelectric dams November 22, Squatting on spongy soil, a climate scientist lays a small cone-shaped device to "measure the breathing" of a peat bog in the northern part of Canada's Quebec province.
Pacific Ocean typhoons could be intensifying more than previously projected November 21, Changes to the uppermost layer of Earth's oceans due to rising temperatures are likely causing an increase in intense Pacific Ocean typhoons, suggesting strong typhoons may occur more frequently than scientists project in Discovery of a new gene could shed light on chemical exposure effects in humans November 21, The discovery of a new gene in zebrafish could lead to a better understanding of how exposure to chemicals leads to disease in humans, according to a new Oregon State University study.
Researchers find simple way to massively improve crop loss simulations November 21, Droughts or heat waves have consequences that spread beyond farmers anxiously watching their fields; these fluctuations in crop yields can send shockwaves through local and global food supplies and prices.Hydraulic fracturing and horizontal drilling are safely unlocking vast U.S.
reserves of oil and natural gas found in shale and other tight-rock formations. Developing energy from shale is an advanced process that uses the latest drilling technologies and equipment.
As for what fracking means to the United States – the answers are security, economic growth and jobs, jobs, jobs. The first hydraulic fracturing treatment was pumped in on a gas well operated by Pan American Petroleum Corp.
in the Hugoton field. Kelpper Well No.
1, located in Grant County, Kansas, was a low-productivity well, even though it had been acidized. Hydraulic fracturing (informally known as hydrofracking, fracking, fracing, or hydrofracturing) is a process that typically involves injecting water, sand, and (or) chemicals under high pressure into a bedrock formation via a well.
EPA released the final report for the study of fracking's impact on drinking water in December Here you can find a summary of the report, the full report, some . Hydraulic fracturing, commonly called fracking, is a drilling technique used for extracting oil or natural gas from deep underground.
Fracking is a hotly debated environmental and political issue. Our study of hydraulic fracturing and its potential impact on drinking water resources: We studied the relationship between hydraulic fracturing for oil and natural gas and drinking water resources. The study includes a review of published literature, analysis of existing data, scenario evaluation and modeling, laboratory studies, and case studies.
