Recommended: Benefits and drawbacks of using Managed Pressure Drilling

Managed Pressure Drilling (MPD) technology has progressed on land drilling programs. However, it has been only relatively recently that the technology has found an important place in the minds of offshore drilling decision-makers. With the majority of the world’s remaining prospects for oil and gas being economically un-drillable with conventional-wisdom casing set points and fluids programs, MPD is now being regarded as a technology which can render a significant increase in economic drill-ability by decreasing excessive drilling-related costs normally associated with conventional offshore drilling. Managed Pressure Drilling (MPD) uses a closed and pressurised system to gain a more precise control of bottom hole pressure. This level of precision …show more content…

Should The United States Drill For Alaska Dbq Essay

722 Words | 3 Pages

For centuries the United States has been a beacon of hope for environmentalism, and it is imperative for our country that we preserve this identity. The Arctic National Wildlife Refuge or ANWR is in the secluded northeastern corner of Alaska and could contain large reserves of oil in the Prudhoe Bay region. The question of whether or not to drill for oil has been a controversial topic in American politics for decades, though the evidence will show that drilling for oil is a mistake for this country. This is because it will devastate and destroy the fragile environment. Additionally, drilling in Prudhoe Bay will not solve our oil problems.

Alaska is a place for pioneers, and no more so than today as the state faces this century’s biggest challenges—energy development and climate change. Just as they did 30 years ago when the Trans-Alaskan Pipeline System jump-started their oil economy, residents of the Last Frontier are surveying their options and reinventing themselves. Resource extraction still dominates the state, but citizens and politicians are now engaging in open discussions about how new mining, drilling, and pipeline projects will impact the environment. Damage from melting permafrost is proving that rising temperatures affect people and jobs as well as polar bears. Backpackers should pay attention to Alaska, and not only because its peaks and glaciers inspire those

These highlighted such features as obstructions, existing pipelines and conservation areas. Taking the results of these studies into consideration the most direct pipeline route was used in order to minimize any impact on marine life. An additional reason for choosing the shortest route was to minimize the possibility of rupture which can cause severe environmental damage. Pipes were laid parallel to existing pipes if possible in order to produce less of an environmental impact and risk to other potential seabed users. Although it was preferable to avoid pipeline burial due to the length of time it can take for re-colonisation by marine species it was considered necessary to bury Pipeline A. Pipes A and B are both made of high quality corrosion resistant material, able to withstand high pressure and will be protected against upheaval buckling in order to avoid pipeline rupture which may result in oil spills.
