short of drilling wells. Geologists look for reservoir traps = underground formations favorable to the accumulation of oil and gas. Oil and gas exploration is the search for reservoir traps. There are two types of reservoir traps: Structural and stratigraphic Geophysical survey: an exploration method whereby devices‚ such as a seismograph is used to develop a contour map of an area in order to determine which land to lease and where to locate an exploratory well There

process is quite simple; the idea is that millions of gallons of water‚ sand‚ and other such chemicals are pumped into the ground to break up shales of rocks that then release natural gasses (Osborn). The gasses are then able to move freely to the wells. Most of the fluid sent to the ground are sand and water; the process of fracking has become more and more common in the United States and is projected to increase to be the only efficient

Ocassionally elk‚ mule deer‚ pronghorn antelope and other wild life‚ including the imperiled greater sage grouse‚ descent from their habitats atop the mesa and gingerly make their way around and between the questar wells around Pinedale. Not suprisingly‚ environmentalist are at war with questar‚ whose

Hydraulic fracturing or “fracking” is the process of drilling and injecting fluid into the ground at high pressures in order to release natural gas from shale rocks by fracturing them. It takes an abundance of resources to create just one fracking well. Each gas well needs on average four hundred tanker trucks to carry water and supplies to the site. Fracking uses a great deal of water. Each fracturing job requires one to eight million gallons of water to complete it. Hydraulic fracturing has a huge effect

gallons of water into the ground to crack shale rock around a gas well. When the shale rocks around the wells are cracked‚ it allows natural gas‚ specifically methane‚ to flow into the wells. To fracture the shale rock‚ the water injected into the ground has to be at a very high pressure and is loaded with sand and about 40‚000 gallons of 600 different dangerous chemicals. Once the natural gas has flown into the underground well‚ it can be extracted and stored in tanks above ground to later be

historic boom in production of domestic gas and oil. Over the past few years‚ advances in fracking creates fractures that extend from wells into oil and gas formations by pumping highly-pressurized fluid; water‚ sand‚ ceramic beads‚ and a mixture of chemicals into the oil or gas formation. As this fluid holds the underground fissures open‚ oil and gas flow up the well to the surface where they can be recovered. Over the past few years‚ advances in fracking technology have made tremendous reserves

including crew training. Barstow‚ Rohde‚ and Saul (2010) note that the Macondo well had fallen behind schedule from the beginning‚ and the Deepwater Horizon rig had been sent into order to drill quickly. On the morning of April 20‚ crews were performing a negative pressure test‚ which resulted in oil and gas seeping into the well. Eventually‚ a significant amount of oil and gas‚ perhaps hundreds of barrels worth‚ moved up the well past the Deepwater Horizon’s blowout preventer. This material pushed its

Local residents are concerned about the additives used in Talismans fracking process‚ as well as the depletion of their fresh water source. The major environmental concerns associated with hydraulic fracturing include the presence of fracking additives in ground water supply‚ human induced earthquakes‚ and the use of large amounts of fresh

Fracking is accomplished when a well with veins (small branching off pathways)‚ is drilled. This pathway altogether tends to be over a mile long. Shale containing gas or oil is fractured by a highly pressurized concoction‚ composed of: water‚ sand‚ and an array of toxic chemicals‚ including but not limited to‚ hydrochloric acid and ethanol glycol. The fracturing creates fissures‚ long narrow openings of breakage. The gas or oil is discharged from the fissures‚ into the well. The gas or oil slowly works
