Fracking the shale formation

Hydraulic fracturing (also fracking, fraccing, frac'ing, hydrofracturing or hydrofracking) is a well stimulation technique in which rock is fractured by a pressurized liquid. 1 north dakota's bakken formation is a layer of dense, oil-bearing rock found at a depth of about 2 miles to tap it, oil companies drill to the hydrocarbon-rich stratum, then curve the well bore. The monterey formation is geologically complex, a brittle shale rock that has been broken and scrambled for millenniums oil in the shale, formed by the remains of ancient plants and animals, is. Drilling companies suggest trillions of cubic feet of shale gas may be recoverable from underneath parts of the uk through a process known as fracking hydraulic fracturing, or fracking, is a. Epa works with states and other key stakeholders, through sound scientific research and regulation to help ensure that natural gas extraction from shale formations, also called fracking or hydrofracking, does not harm public health and the environment.

fracking the shale formation Here we describe the seven major us shale plays and  gion is good for fracking, and wells typically cost $65 to  gas formations at depths of 11,000 to 15,000.

The ari assessment of shale formations presented in this report, however, looks exclusively at shale resources and does not consider other types of tight formations the report covers the most prospective shale formations in a group of 41 countries that demonstrate. Natural gas production from shale formations (fine-grained sedimentary rocks with relatively low permeability that can be rich sources of petroleum and natural gas) is one of the most rapidly-growing trends in us domestic energy exploration and production. The niobrara shale formation otherwise known as the niobrara chalk is a geologic formation that spreads over wyoming, nebraska, colorado, and kansas with the largest part being located in colorado.

An unconventional gas well is a well that is drilled into an unconventional formation, which is defined as a geologic shale formation below the base of the elk sandstone or its geologic equivalent where natural gas generally cannot be produced except by horizontal or vertical well bores stimulated by hydraulic fracturing. The rogersville shale is a cambrian-age formation that lies under much of eastern kentucky and extends into west virginia two test wells have already been drilled: one in lawrence county, and. Oil shale is a type of sedimentary rock that is rich in kerogen kerogen is a part of rock that breaks down and releases hydrocarbons when heated hydrocarbons are substances made entirely of hydrogen and carbon. Hydraulic fracturing, commonly referred to as fracking, is a drilling technique that allows the extraction of previously inaccessible natural gas from shale formations. Of the states over the marcellus shale formation, fracking is already underway in ohio, pennsylvania and west virginia fracking is also being used to reach gas in states beyond the marcellus.

Initial production rates in tight oil formations continue to rise eia expects near-term decline in natural gas production in major shale regions falling rig counts drive projected near-term oil production decline in 3 key us regions. Radioactivity in fracking wastewater comes from the interaction between a chemical slurry and ancient shale during the hydraulic fracturing process, according to dartmouth college research. West virginia lies over the marcellus shale formation, and the far western edge of the state also lies over the devonian shale formation 1 the utica shale formation lies below the marcellus formation 2 and is just beginning to be developed in west virginia 3 the number of natural gas wells in west virginia has continued to rise over the past. Shale gas, are therefore more likely now to be explored for their shale potential shale gas is extracted from solid rock using a process called hydraulic fracturing, or 'fracking.

Fracking the shale formation

Shale gas formations are unconventional reservoirs - ie, reservoirs of low permeability permeability refers to the capacity of a porous, sediment, soil - or rock in this case - to transmit a fluid. 3 water resources and natural gas production from the marcellus shale figure 4 drilling, the shale formation is then stimulated by hydraulic fracturing. The largest oil shale formation in the world is believed to be the green river formation, right here in the united states, beneath parts of colorado, utah, and wyoming the united states geological survey (usgs) estimates that there are approximately 3 trillion barrels of oil in the green river formation.

Hydraulic fracturing or fracking creates fractures in the shale formation to release the gas a fracturing fluid is pumped under high pressure (ca 100 bar) into the drilling pipe to widen fractures in the rock or to create new ones. The point has been recognized since the hydraulic fracturing revolution began a decade ago in the marcellus shale formation lying thousands of feet down in pennsylvania, west virginia and ohio. The marcellus formation (also classified as the marcellus subgroup of the hamilton group, marcellus member of the romney formation, or simply the marcellus shale) is a middle devonian age unit of marine sedimentary rock found in eastern north america.

The shale of the monterey formation averages nearly 1,900 feet thick and more than 11,200 feet deep, compared to an average thickness of just 22 feet and depth of 6,000 feet for the bakken shale. The woodford shale, the state's largest shale formation, straddles the ardmore basin and the arkoma basin in 2011, the us energy information administration estimated that the woodford shale contained up to 222 trillion cubic feet of technically recoverable natural gas. The placement of hydraulic fracturing treatments underground is sequenced to meet the particular needs of the formation the sequence noted below from a marcellus shale in pennsylvania is just one example.
