What is onshore and offshore petroleum exploration?
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.
How long does a work day on an offshore rig take?

How do oil rigs function?
There are basically 2 types of rigs. 1) Drilling Rig The function of this rig is drilling a well down to the production zone then installs a casing in it. There are various types for offshore drilling and there are types for onshore drilling. 2) Production Platform (Offshore) The function of this rig is for producing oil. It consists of not only a single well like on an onshore pad, but I have seen platforms with 20 to 50 wells. They are not drilled straight down like most onshore wells, but they are deviated and get drilled in and arc, away from the platform and ends up being somewhat horizontal. Wells can be anything from 1000+ and up to a few thousand feet deep. A work-over rig on the platform uses equipment to perforate the casing at the desired production zone and a screen is installed to minimize sand flowing into the well. Pumps are installed into wells to produce the oil. Depending on how far the platform is located from land, a pipe line can tranport the oil to land or in most cases where platforms are to far offshore, the surrounding platforms pump the oil to a FPSO which is basically a huge oil tanker that transfers oil to oil tanker ships. Onshore operations are different. A well is drilled and a wellhead is installed. Piping from the wellhead leads to a manifold which is connected to the surrounding wells. From there oil gets pumped to gathering stations then to refineries.
What does Offshore Software Development mainly do?
In simple terms, businesses with offshore software development have engineers that essentially work in tandem with those that are in-house to remotely handle project requirements or business needs. They work as help away from the central hub of the company basically.
What is offshore engineering?
when you do engineering at offshore, it is known as offshore engineering. It is just the opposite of on shore engineering . He He He He He He
What is the difference between offshore and onshore?
onshore means it is on land and offshore on sea.
Which oil field is asab from onshore or offshore?
Assab is an onshore oil field
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 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 are the dangers of offshore and onshore winds?
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.
Are Ireland's Prevailing wind onshore or offshore?
on-shore
Where are offshore and onshore wind farms located and where are they planned to be built?
The Netherlands
What are the differences of the offshore and onshore dichotomy?
Onshore/offshore dichotomy is way of allocating the revenue accrued from exploitation and exploration of crude oil. Such revenue is divided into onshore revenue (revenue accrued from oil drilled onshore (on land) and offshore revenue (accrued from oil drilled from littoral zone).The dichotomy implies the revenue from offshore crude belong to a sovereign nation and not to the coastal communities, and thus must be shared among the states that make up the nation, while onshore revenue belongs to the coastal communities (termed oil producing communities) on which land the crude is drilled.
Is all crude oil drilled offshore?
No, not at all. Offshore only started when onshore became more difficult to find.
What is offshore and onshore?
well the exact term of offshore is that is is not on this planet. it is very hard to get, and to find. on shore is that it is on earth and pretty local to get at. onshore is mostly were we get out resources :-)
What is Puerto Rico natural resources?
Onshore and offshore oil and some copper and nickel.
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.
