The Oil Drilling Industry Jobs Overview

The work on a certain area regarding the petroleum extraction involves four major sectors of the oil and gas industry, each one with its own ramifications and additional sectors. Therefore, finding a job in this sector will give you the opportunity to experience many positions and build a strong career in the Oil and Gas industry.

The drilling sector of the Oil and Gas industry operates by using drilling oil rigs and it has a crucial role in the search for petroleum and natural gas.

All About Drilling Oil Rigs

You can start your job search on the onshore or offshore drilling oil rigs which are used for drilling holes in the ground in areas that were previously determined to contain petroleum reserves by the geologists and other scientists.

The right depth is predetermined in order to benefit from the optimum yield of petroleum. After the hole is ready, the drilling crew will introduce into the well bore a casing then pour concrete around it.

The drilling process is continuously evolving, as the reserves of crude oil are getting harder to find and exploit. You can look for a job in the crews that experience the new drilling methods. Those are successfully used when searching for the crude oil:

  • Vertical drilling, which is the conventional technique;
  • Horizontal drilling allows the crew to go down in the ground then move horizontally;
  • Slant drilling means drilling in a certain angle.

The types of oil drilling rigs used by companies depend on certain decisive factors: type of well, location and the environment. When job hunting for a position in the oil drilling industry you should consider working in difficult environments, because the drilling rigs are placed all over the world, on shore or on seas. They can be categorized in the following types:

  1. Platforms are immobile structures used for drilling and they are made from cement or steel.
  2. Jackups can be moved due to their bottom supports. They consist from a main deck which is supported by column-like legs or an open-truss.
  3. Floaters (semi submersible structures) are sustained by giant pontoons or hollow columns. Those elements can be filled with water or emptied until the floating structure reaches the desired depth. The floaters are mainly used for drilling new wells.

More About the Drilling Equipment

The Offshore Drilling Equipment includes an accommodation section for the employees, with modules for sleeping and eating, and offices too.

  • In case of emergency, the employees must go in the Temporary Safe Refuge, or the TSR. Safety equipment includes a lifeboat system that can be easily released into the water in any dangerous conditions and can be used to carry the employees on to a safe place.

If you decide to look for a job in the Oil and Gas industry, some information about the operations and the inner mechanisms of the drilling sector will help you understand better the type of work will you perform. Usually, the drilling oil rigs have a crane used for handling various equipments and materials around the oil area. The workers use derricks when drilling the wells by setting them on skids that have the role of supporting them.

There are modules placed on the oil platform that perform other essential tasks for the oil and gas related operations:

  • The process module is created to separate the oil from the water and gas. After the separation process, the water is treated then expelled back into the sea, without harming the marine environment.
  • The drilling mud module is designed for mixing chemicals, water and clay in order to obtain a mixture that is meant to cool the drill bit. It can clean the cuttings of the drill, and improve its functioning.

If you will ever have the chance to work on a drilling oil rig that operates in the cold seas, you will surely notice the ice wall teeth that ease the way of the rig while passing along icebergs. Those are placed below the platform of the oil rig and have a great functionality in lowering the impact when touching an iceberg and the level of the shock produced on the rig structure.

Today, the oil and gas companies are turning more and more profitable despite the shortage of oil all around the world. The fact is that a good part of the profits is re-invested into equipment such as drilling rigs that is used to find new crude oil resources. There are many new rigs in construction and they will be soon available for operations, in the places where the companies detect petroleum reservoirs.
