The organization with the largest share in the oil drill‚ BP (Beyond Petroleum)‚ is still facing consequences of this spill and lost millions of dollars as well as national support. The Obama administration also received criticism for not responding to this crisis quickly enough. This monstrous oil spill created environmental‚ health‚ social‚ and economic problems that were unprecedented‚ and the rippling

sure that the cement used for the well formed a solid seal. The cement did not form the proper barrier that was needed and as a result when BP’s drill bit arrived at the targeted site‚ combustible natural gas mixed with petroleum‚ and they ignited as they pushed up to the surface causing the well to spill an uncontrollable amount into the Gulf of Mexico. This accident could have been totally avoidable had the proper tests been taken and the proper tools for the well had been used. It is at this point

frequently. “Deep well injection involves drilling a hole that is a few thousand feet deep and injecting toxic substances at extremely high pressure so they will penetrate deep into the Earth.” (Saukko Par 2) This is called fracking and is used to bring fossil fuels to the surface. “According to the Environmental Protection Agency (EPA) there are about 360 such deep injection wells in the United States.” (Saukko Par 2) Not only is there deep well injections‚ there are also shallow well injections which

About five kilometers from my farm land‚ a multinational company established a factory for producing soft drinks. The entire land around the factory to an extent of 10 Sq.km was under paddy cultivation. The entire water requirement for the company was from bore wells in the company premises. It is understood from the employees of the company that each bore well is around 1000 ft

Drilling Mud density or specific gravity is the most significant measurement required and no reliable visual estimate exists. The mud density or specific gravity must be accurately measured in order to successfully drill a well hole. The most accurate measurement of mud density is made by using the Mud Balance. Viscosity is the resistance to flow offered by a fluid. The term is loosely applied as the flow properties of drilling mud. The relative viscosity‚ or the cuttings carrying ability of the

construct wells of circular section applying excavation techniques not requiring direct access by man. To drill a well it is necessary to carry out simultaneously the following actions: a) to overcome the resistance of the rock‚ crushing it into small particles measuring just a few mm; b) to remove the rock particles‚ while still acting on fresh material; c) to maintain the stability of the walls of the hole; d) to prevent the fluids contained in the drilled formations from entering the well.

reservoir rock that allow the oil or natural gas to flow more freely to the well bore.” (DEQ) Chemicals and silica sand are added to the fracking water to improve effectiveness and keep the fractures open‚ increasing flow of natural gas. Fracking has been used since the early 1950s to drill vertically‚ strictly where the well pipeline will be placed.

Given these realities‚ we should not abandon the quest to determine the extent of our offshore oil resources and how much can be recovered in a responsible manner.” (“Energy Policy: Should the United States Increase Domestic Production of Oil and Natural Gas?”).

ever-increasing array of well intervention projects. Coiled tubing offers a number of operational and economic advantages‚ including: live well intervention‚ elimination of well kill and potentially damaging heavy-weight kill fluids‚ reduced operational footprint‚ horizontal intervention‚ and the ability to intervene without a rig. These advantages have led to the development of truly fit-for-purpose coiled tubing systems from the industry’s largest provider of coiled tubing well intervention solutions
