Hydraulic fracturing process

Many media reports, hydraulic fracturing is not a " drilling process ." , After the completion of drilling using Maide hydraulic fracturing benifits . Simply put, is the use of hydraulic fracturing fluids and materials , create or restore the formation of small well fracking to stimulate the production of new and existing oil and gas wells. This creates a path to increase the rate of fluid can be produced from the reservoir, in some cases , by the many hundreds of percent, the method comprising the following steps to protect the water supply . To ensure that neither the final fluid to be pumped through the hole , nor will eventually be collected by the oil or gas into the water, surface or intermediate casing steel insert well depth between 1,000 and 4,000
Feet. These sleeves " string" and drilling ( wells ) , known as the space between the rings are filled cement. Once the cement , and then continue drilling or transition from the ground to the bottom of the next depth carburizing steel housing. This process is repeated , using smaller steel casing each time , until it reaches the oil and gas reservoirs ( typically 6,000 to 10,000 feet ) . The following diagram is a typical Eagle Ford Shale wells of a promotion in south-central Texas . Here there is a more detailed housing and groundwater protection role.
