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 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.

How many barrels does an oil rig produce per day?

The daily oil production of an oil rig can vary widely depending on factors such as the type of rig, the location, and the reservoir's characteristics. On average, a single offshore oil rig can produce anywhere from a few thousand to over 100,000 barrels of oil per day. For example, large deep-water rigs may produce upwards of 50,000 to 100,000 barrels daily, while smaller onshore rigs may generate significantly less. Overall, production levels are highly variable and depend on numerous operational and geological factors.


How do you work on an oil rig?

Apply for a job at oilrig.net and see if you get accepted, ive been working at the oil rig for about 3 years now and i love it. You get to meet a lot of cool people and its just a great experience.

What is onshore oil rig mechanics scope of work?

The scope of work for onshore oil rig mechanics includes the maintenance, repair, and operation of drilling equipment and machinery used in oil extraction. This involves troubleshooting mechanical issues, performing routine inspections, and ensuring compliance with safety regulations. Mechanics are also responsible for installing new equipment and conducting preventive maintenance to minimize downtime. Additionally, they may collaborate with engineers and other technicians to enhance operational efficiency and address any technical challenges that arise on the rig.

How many moving parts does an oil rig have?

An oil rig can have thousands of moving parts, depending on its design and complexity. Key components include the drilling rig itself, pumps, motors, and various mechanical systems used for drilling and extracting oil. The exact number varies based on the type of rig (e.g., offshore vs. onshore) and the technology employed. Regular maintenance is crucial to ensure these moving parts function effectively.

How do onshore turbines work?

Onshore turbines work by converting the kinetic energy in wind into mechanical power. When the wind blows, it causes the turbine blades to rotate, which then turns a generator to produce electricity. This electricity is then either used on-site or transmitted to the grid for distribution.


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.
