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.
He has been covering this issue very closely for the past year and has broken a number of stories. Links Transcript This is a rush transcript. Copy may not be in its final form.
We turn now to another story about water. New evidence has emerged possibly linking natural gas drilling to groundwater contamination. ProPublica reports federal officials in Wyoming have found that at least three water wells contain chemicals used in the natural gas drilling process of hydraulic fracturing.
The Wyoming study marks the first time the Environmental Protection Agency has undertaken its own water analysis in response to complaints of contamination in drilling areas.
Residents in Pavillion, Wyoming, have complained for years that their water wells turned sour and reeked of fuel vapors shortly after drilling took place nearby.
ProPublica reports precise details about the nature and cause of the contamination have been difficult for scientists to collect, in part because the identity of the chemicals used by the gas industry for drilling and fracturing are protected as trade secrets. But first we want to play an excerpt from a new documentary called Split Estate by Debra Anderson.
The documentary examines the impact the oil and gas drilling boom has had in the Rocky Mountain West. This part deals with Garfield County, Colorado. Insome residents in Garfield County began to complain that they were getting sick as a result of the drilling activities in their neighborhoods.
A young woman from Silt, Laura Amos, was one of the earliest and loudest voices. As everyone in this room probably knows, my groundwater has been contaminated with methane, Williams Fork gas. There are a lot of people in this room with contamination and pollution issues.
Ingas wells were drilled using the fracking technique a mere feet from the Amos home. Underground, the drilling breached their water well, causing their drinking water to fill with grey sediment and fizz like soda pop.
The Colorado Oil and Gas Conservation Commission tested the water well and found methane but said it was safe.
The Amoses stopped drinking the water but continued to bathe in it. A young woman called me from Garfield County and said that she had developed a rare adrenal tumor, that she had had this incident with her well.
That was the beginning. I mean, when she called, it just sent chills up and down my spine. She had been breast-feeding her daughter through the period when they were using the water that they were told was safe. She was bathing her baby in the water in their home.
They were breathing the stuff that was coming into their house. She later found out that a chemical that had been used in the fracking has been linked to adrenal gland tumors. When she went to EnCana, they denied using it on that well or any other.Hydraulic fracturing, or fracking, wrenches open rock deep beneath the Earth’s surface, freeing the natural gas that is trapped inside.
Gas recovery is a game changer, a bridge to the future. The gas, primarily methane, is cheap and relatively clean. Environmental Protection Agency (EPA), Fracking, or Hydraulic Fracturing is a method used to extract underground resources including oil, natural gas, and geothermal energy by injecting high pressure fluid into a geologic formation containing oil or natural gas deposits.
Because of the success in drilling in tight formation thanks to horizontal drilling and fracking, Cantafio oil and gas, LLC, -like many in our industry- has an abundance of natural gas reserves. A constraint on profitability is that like all U.S businesses we are legally prohibited from selling natural gas abroad.
Aug 21, · Fracking is used to extract natural gas from shale layers located deep in the ground. The impermeability of the shale layers leads to the gas being trapped.
The rocks are blasted with pressurized water that contain sand and chemicals capable of increasing friction between the rocks and water. - Fracking in the natural gas community is a vital part of the recovery of natural gas.
Fracking is a controversial subject right now; some environmentalists believe that fracking is detrimental for the environment, although some people believe that fracking is a necessity for the future of fuel.
