Well Intervention and Its Benefits

Currently, there are over 5000 subsea ells globally, and more are still in the drilling process every day. Therefore, offshore well intervention companies offer various techniques of well intervention to help keep up with the rise in global demand for oil and gas.

Well intervention is beneficial in extending the productive life of any aging well and repairing the damaged and underperforming ones. This results in higher profits for oil and gas companies. PRT Offshore specializes in this arena of offshore work to help the companies make some profits with their services.

What Is Well Intervention?

Well intervention is a process for enhancing the quality of the subsea well by providing data to help manage the well’s production rate or shutting off and safely abandoning a flowing well. One of the most challenging issues in well intervention includes keeping the costs down. Therefore, it is essential to do extensive preplanning to determine the most effective potential solutions as the team mitigates different known and unknown risks.

Sometimes in the life of oil and gas, the parts will need maintenance, repair, and replacement. This is when operators seek the help of intervention specialists in well intervention companies to help with the problems.

There are two categories that intervention falls into, including light and heavy. For light interventions, the technical team will lower its tools and sensors in the well as they also contain pressure at the surface. During a heavy intervention, the specialist may stop producing at the formation before they make significant equipment changes.

Well service specialists usually perform intervention through the use of slicklines, wirelines, and coiled tubing. The systems allow them to reduce the risk of blockages in the well. The specialists also perform light interventions for changing and adjusting downhole equipment like valves and pumps. They also perform the interventions for gathering downhole pressure, flow data, or temperature.

In heavy interventions, the rig crew removes the wellhead and any other pressure barrier from a well to give full access to the wellbore. The operations need a rig to eliminate and reinstall the wellhead and completion apparatus.

Well intervention companies use heavy interventions to replace parts like tubing strings and pumps that they cannot repossess using light interventions. They perform some heavy interventions to plug and abandon the original producing zone to reconfigure the well to produce from secondary zones. Such operations are also known as “recompletions”.

Advantages Of Well Intervention

• It helps wells operate better and more efficiently
• It helps to solve any unforeseen problem quickly before it becomes a problem
• Rejuvenates production
• It helps companies make informed decisions with access to essential data
• Reduces risks and nonproductive time (NPT)
• Increase ROI and reduces the cost

The well intervention market is still in its infancy but has huge growth potential. Due to the increase in the number of subsea wells, there is also a high demand and frequency for needed servicing through interventions. To determine which solution makes more sense requires a company to balance between vessels and high-risk systems.
