onshore is oil well drilled on land.
offshore is oil well drilled in sea/ocean.
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.
onshore means it is on land and offshore on sea.
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.
Petroleum exploration is where a rig or ship is used to drill into the earth or seabed to locate oil reserves. For offshore exploration a drill ship, jack-up drilling rig or floating drilling rig can be used. For onshore applications mobile drilling rig is used.
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.
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.
Offshore refers to activities that take place in a foreign country, often for tax or cost-saving purposes, while onshore refers to activities that occur within the country's borders. Offshore activities often involve outsourcing to countries with lower labor costs, while onshore activities are typically closer to the company's base of operations. Offshore can also refer to activities that take place in international waters, such as offshore drilling for oil.

Both of them are outsourcing services that deal with software development. The difference between them is that when you say "offshore", it means overseas. So if you avail of offshore software outsourcing, you are outsourcing software development to a different country. When you say onshore software outsourcing, it is still outsourcing but the company you outsourced the software development is within your country.
No, any production of gas and oil, whether offshore or onshore, increases the effects of global warming. Burning fossil fuels (coal, oil and natural gas) releases carbon dioxide, one of the greenhouse gases responsible.
Offshore winds will blow the unwary captain onto shoals or reefs. Onshore winds will blow the unwary captain away from his next landmark or landfall.
The cost of oil drilling can vary widely depending on factors such as location, depth, and technology used. Onshore drilling typically costs between $500,000 to $5 million per well, while offshore drilling costs can range from $100 million to over $1 billion per well. These costs include expenses for equipment, labor, permits, and other logistical considerations.
