Many of the world’s new reserves are discoveries made below these existing‚ mature reservoirs. Drilling activities in or near producing or previously abandoned reservoirs often encounter large variations in pressure gradient as depleted layers or low pressured zones are exposed during the drilling process. Zones with pressures inconsistent with the overburden are often encountered‚ if conventional drilling techniques are used‚ then the higher mud weight used to hold back the target interval may result

The Deepwater Horizon was essentially a massive floating deep water drilling rig‚ which could operate in depth of as much as 10‚000 feet under water. The drilling rig was owned by Transocean. At the time of the explosion‚ the drilling rig was operating at 5100 feet in depth of water‚ drilling an exploratory well around 35‚050 feet deep‚ in the Mocando Prospect‚ located at the Gulf of Mexico.

Fracking as a method for oil and gas extraction is also more economically viable than conventional or horizontal drilling. The last reason is that the process has driven down gas prices and offered gas security to both the United States and Canada for about 100 years. This is why we should keep fracking.

because in one sense drilling off the coast and in the Gulf of Mexico would help save our country money because we would not have to buy our oil from other countries. I also think it is somewhat of a good idea because if we were to drill here instead of buying our oil from other countries it would help provide more jobs for Americans which we really need. I also believe that on the other hand it would be better to continue buying our oil from other countries because drilling off the coast here could

it‚ is in the midst of having an oil crisis. Our nation starves and bends at the will of this dreadful calamity. Our deprivation for this atrocious corruption has led us to look for oil deposits in the Alaskan Wilderness. The US needs oil and by drilling for oil on our own land‚ we would help our economy‚ but in doing so would destroy the beauty of the wilderness and harm many others. The matter on hand is that should we drill for oil in Alaska’s wilderness? My opinion and answer to this question

non-dependent on oil‚ however using other sources will decrease the costs. Though making the change from oil could be very expensive‚ it is necessary. I stand very firm with the fact that we need to end foreign drilling and start searching for oil in our own boundaries of the United States. Drilling in Alaska‚ the Gulf Coast‚ and other unexplored areas will help the economy by creating more jobs for Americans and lowering the cost for oil. S.

Fred Bodman Mr. Shawn Welch ENG-101-BR6 04 April 2013 Tough Bits Drilling is the quickest process of removing lots of material. Physical properties of material have a wide range of characteristics and need to have the appropriate drill composition to work properly and efficiently. Many different materials are used for or on drill bits‚ depending on the required application. Many hard materials‚ such as carbides‚ are much more brittle than steel and are far more subject to breaking‚ especially if

for energy development.[Hydro-fracking is different from conventional natural gas drilling because it uses a lot more water (billions of gallons). There’s an increased potential for toxicity and long term impacts in hydro-fracking as well. It also has several environemental impacts‚ including habitat disturbance and water contamination. These are all new components‚ which differ from the original horizontal drilling of gas. These new factors‚ emerging from hyrdro-fracking‚ has been an on going contraversy
