Most offshore drilling occurs?
Near trenches!! Hope that helps and its 2010 yippy
What are some problems with land use?
Jetports, petroleum refineries, offshore tanker depots, drilling rigs, nuclear power stations, high-voltage transmission lines, dams, shopping centers, and housing developments.
What are the pros and cons of oil drilling in Antarctica?
At present, drilling for oil is prohibited until 2048. See Wikipedia link. Second, there has been some drilling in the 1970's offshore in the Ross Sea, but only traces of gas were found. It will be hard to justify spending money to explore for oil, as the cost of drilling and producing is very high. So the ban on exploration may continue after 2048. See second link.
Who is in charge of drilling rigs?
This is a good question! I would like to broaden the question a bit as to who makes the decision on a drilling rig. Of particular interest is the offshore drilling rig, where there are responsibilities for quick decisions on the rig floor, and others made from land offices. Routine decisions can be made on the rig. Other decisions are made from land office. These land offices may be in the particular company where the drilling is occuring, but others may require the home office approval. Drilling engineers, production engineers, reservoir engineers, geophysicists, and geologists may all be involved. Often, the drilling rig is leased from a service company. They may contract the rig on a turnkey or day rate basis. A day rate basis is very common, as the service company is not taking a risk if the drilling takes longer than expected. The rig has a crew which is the service company supervisors job to supervise. The well is drilled per the contracting oil company's (lease holder) plan. At all times, there is a company representative or "company man", present to make decisions as the drilling progresses. The company man may modify the plan however modifications to plan often require land office approvals. Some decisions are critical, such as whether to test a prospective zone. Drilling rigs run 24 hours a day/ 7 days a week, so there is a hectic period between the first encounter of a potential producing zone and the testing plan. Ultimately, the testing plan must have the agreement of the operator and all partners (lease holder group).
How is petroleum removed from the earth?
Oil is produced by wells. Oil wells are drilled on land and offshore in locations likely to contain oil.
What is the deference between onshore and offshore production?
I assume you mean "difference" and not "deference". Onshore means on dry land. Offshore means out in the water. Offshore drilling is out in the water, like in the Gulf of Mexico. Onshore drilling means on land, like in Wyoming and Texas.
What is Diamond Offshore Drilling's population?
The population of Diamond Offshore Drilling is 4,200.
What is an offshore platform and how is it different an onshore drilling rig?
An offshore platform is a structure that is installed over as group of wells that was drilled by an offshore drilling rig. The function of the platform is to produce the oil from these wells. A platform can be mounted to the seabed or could be a floating type platform. Offshore drilling rigs are for drilling the wells and are mobile and moved from area to area. Onshore drilling rigs are mobile units too and are moved from pad to pad for drilling and exploration. After a well is drilled onshore, a wellhead is installed on the well. There is no need for a platform as this only economically viable in offshore applications. There have been cases where an offshore well was drilled from land into the sea, but operated from land. This can only be possible if the oil formation is not too far offshore.
What is the difference between onshore and offshore drilling?
onshore is oil well drilled on land. offshore is oil well drilled in sea/ocean.
What has the author William J Renfro written?
William J. Renfro has written: 'The mobile offshore drilling industry in the Southwest and the financing of mobile offshore drilling units' -- subject(s): Offshore oil well drilling, Finance
What are the pros and cons of off-shore drilling?
Pros of offshore drilling are lower prices and increased domestic production. Cons of offshore drilling are carbon emissions and environmental hazards.
How many natural disasters were caused by offshore drilling?
None. Any disaster caused by offshore drilling would be a man-made disaster.
Does offshore oil drilling harm wildlife?
Yes, minorly, it is drilling mud.
Where can one find a list of offshore drilling jobs?
One can find a list of offshore drilling jobs on many websites. Craigslist has a category designated to finding workers for these types of jobs. One can find a few listings of offshore drilling jobs on this website.
What is Offshore oil drilling?
Offshore oil drilling refers to the extraction of oil from beneath the seabed in oceans, seas, or other large bodies of water. You can check out mineralview (dot) com blogs for more information.
What is onshore oil?
Onshore oil is a nickname for oil that is obtained through oil drilling that is completely on land, as opposed to offshore oil, which is collected from drilling under the seafloor with floating oil rigs.
Who is the largest offshore drilling contractor in the world?
hercules
