Drilling for oil on land is usually cheaper than drilling under the seabed due to several factors. On land, the infrastructure costs are lower, as there is no need for specialized equipment, platforms, or pipelines. Additionally, the depth and pressure of the reservoirs under the seabed can be much higher, requiring more complex and expensive drilling techniques. The harsh marine environment also leads to increased operational and maintenance costs for offshore drilling.
No company is currently (as of May 21, 2009) drilling for oil in Antartica. I base this on a search of the Internet.
Both are mined or extracted with modern equipment, including offshore platforms, excavators, loaders and drills. For natural resource transportation, dump trucks (for ore hauling) and pipelines or oil tankers are used.
The disadvantages: domestic oil, if located, would not be ready to use for about ten years; oil consumption needs to be minimized, not expanded--Californians didn't take alternatives to the automobile seriously until the price of gas sky- rocketed, and that's a good thing because driving needs to be reduced; drilling locations so far include offshore in the Gulf, California and presumably any coastal area in the U.S. where oil is surmised to be, the Arctic Wilderness--and there are major obstacles with poor solutions. The advantages are the potential future ability of the U.S to supply its own oil if it reduces consumption to a sustainable level and the fact that the extraction of oil adds hundreds of thousands of dollars to state economies.
your oil glands produce oil automaticly
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.
Yes, minorly, it is drilling mud.

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.
Probably inevitable.

onshore is oil well drilled on land. offshore is oil well drilled in sea/ocean.

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.
it is good because we are so dipendent on foreign oil
