Deepwater surfaces are among the most complicated practices faced by engineers globally. It requires the skills, knowledge, and experience from experts to overcome the challenges. The services range from repair, maintenance, and improvement, especially in the oil and gas industries. Unlike onshore services, offshore services are more costly but worth the price. The project includes well intervention, deep water topside, gas hydrates, and the formation of salts. Let’s find out more about well intervention process.

A well has to undergo an intervention process due to mechanical problems, poor flow, or reservoir changes to maximize production. Deepwater well intervention in subsea is more costly than dry wells due to the high cost of subsea equipment and vessels. Regardless of the down holes application process used, whether single or multiple, ensure the problem is solved amicably. Work with a company that offers top-rated well intervention services at an affordable rate. The process of intervention occurs in two primary categories known as light and heavy interventions.
Light intervention is a powerful solution that helps in the operations of less complicated wellheads. An operator takes down a tool to the surface of a well that is still under pressure. It helps reduce well blockages or adjust down holes equipment such as a valve or gathering down holes pressure and data flow. The process takes place through:
Pumping is a simple and cheaper form of well intervention process that does not require complicated hardware to be inserted inside the wellheads. It promotes gas movement from one vessel to another.
Wireline is suitable for wells that are still under pressure. It ranges from well cleaning, logging, or perforating. The tools are continuously inversed and pulled out of the well surface using a braided wire. Wireline tools have an inbuilt reel power supply mounted on the surface to speed the process.
Coiled tubing occurs when a steel pipe is continuously inserted inside the wellbore surface to circulate the fluid. More advanced coil tube equipment is made of thick alloys to withstand extreme pressure and is resistant to corrosion, making the process possible. Also, the coil tubing equipment is cost-friendly.
Heavy intervention operates using a rig to reinstall, replace or remove wellheads that cannot be retrieved using light interventions such as pumps or tubing strings. Heavy intervention sometimes occurs when reconfiguring a well or during the original production from a secondary zone in a process called completion. The heavy intervention takes place using.
Hydraulic workover is a rig less well-intervention process suitable for more complicated jobs such as deepwater reservoirs operating under extreme pressure. The pipe length is adjusted depending on the reservoir depth.
When production life comes to an end, every oil and gas company ensures they repair, replace, and maintain offshore deep water. However, due to the complicated nature of the work, most companies charge higher rates. Companies like PRT Offshore offer deepwater solutions at a cost-friendly price but simultaneously help restore the well and increases the production rate.
