The Upper Big Branch Mine disaster occurred on April 5th‚ 2010‚ in Raleigh County‚ West Virginia. The mine was located in Montcoal and owned by Massey Energy‚ but bought out by Alpha Natural Resources in 2011. Twenty-Nine of the thirty one miners at the site were killed by the explosion. A state funded independent investigation would later find Massey Energy directly responsible for the accident. (www.sourcewatch.org) The explosion was ignited by high methane levels being a contributed factor. You

shale‚ a type of rock" (Source 1). The injection flows down a pipe that is going through the shale. To obtain the natural gas‚ the pressure in the pipe causes the rock around the pipe to crack‚ allowing natural gas to escape. Then‚ the gas flows up the well and is collected. However‚ Hydraulic fracturing should be put to a stop‚ because of health concerns‚ and the effect fracking may have on global warming’s. Hydraulic fracturing uses many chemicals that can cause serious medical problems including cancer

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

Hydraulic fracturing also known as fracking is the process of drilling and injecting fluid into the ground at a high pressure in order to fracture shale rocks to release built up natural gas from inside the ground. Hydraulic fracturings (fracking) exemption from the rules and regulations of the Safe Drinking Water Act (SDWA) needs to be repealed‚ and the new regulations of the Fracking Responsibility and Awareness of Chemicals Act need to be enforced. The repeal of the exemption of fracking from

Brittle shale is more likely to be naturally fractured and will also be more likely to respond well to hydraulic fracturing treatments (Ren et al 2014)‚ (Wang 2008)‚ (Rickman

Schlumberger Rigless Subsea Well Intervention Rigless subsea well intervention is the technology and methodology of reentering a subsea well to perform through-tubing work without a MODU‚ enabling coiled tubing‚ slickline‚ or wireline operations. Schlumberger is introducing two complementary rigless subsea intervention methodologies. These methodologies‚ Open Water Wireline (OWWL) and the Spoolable Compliant Guide (SCG)‚ use common well control equipment accessible from a single vessel to create

According to certain sources‚ Google had abused its dominant position in online search. The costs associated with the antitrust behavior are surprisingly minimal. In fact‚ there was no mention of any mention of the costs that are associated with this antitrust behavior. Likewise‚ there was also no mention of a name for the type of antitrust act that was done here. After

Parc mine is a larger site than the Bwlch Glas mine. The area can be split into two distinct sections; the north and south. The south section of the mine is home to the underground mine entrance. From this‚ contaminated‚ red coloured water flows northwards. It flows through a number of limestone buttresses to neutralise the pH. This water flows into a valley (figure *). On the sides of the valley‚ trees can be seen growing‚ although appear to be experience stunted growth. Also on these slopes‚ fragments

able to set water on fire? Well some people in New York and Pennsylvania are literally able to set their faucet water on fire and shouldn’t be able to. This is caused from fracking. Fracking is a system utilized to extract natural gases from the earth. This essay will discuss the process‚ dangers and loopholes in regulation of this industry.We must understand how hydraulic fracking works. Hydraulic fracking works by extracting natural gas in deep natural gas wells. Once a well is drilled‚ millions of
