What is well intervention vessel?

marine. A dynamically positioned (DP) ship-shaped offshore unit provided with equipment for well stimulation or maintenance (e.g. coil tubing). Such vessels are often able to carry out other tasks as ROV operations and general supply duties.

What is an intervention riser system?

The Intervention Riser System enables access to both conventional and horizontal subsea trees in depths down to 10,000 ft. Our Intervention Riser Systems (IRS) can be utilized for wireline intervention, production logging, coiled-tubing operations, well stimulation and full plug and abandonment operations.

What is well intervention services?

We provide slickline services that log, perforate, set, seal and perform mechanical operations with digital surface control and depth correlation. Our slickline units can perform from the most basic completion intervention to advanced services that are typically performed on electric wireline (e-line).

What is the difference between workover and well intervention?

The term workover is used to refer to any kind of oil well intervention involving invasive techniques, such as wireline, coiled tubing or snubbing. Practically any offshore supply vessel can swiftly be converted into a well intervention unit without any assessment or approval of the modification of the vessel.

What are the three common types of wireline used in well intervention?

Steam injection.

Why do we need to perform well intervention?

With over 5,000 oil and gas wells globally, well intervention is used to extend the life of wells and keep up with the rising demand for oil and gas. All oil and gas wells require maintenance over time, and well intervention helps repair damaged and underperforming wells.

What should there be prior to any well intervention or workover operations?

Before any workover, the well must first be killed. The workover begins by killing the well then removing the wellhead and possibly the flow line, then installing a B.O.P commonly known as a blowout preventer, then lifting the tubing hanger from the casing head, thus beginning to pull the completion out of the well.

What type of intervention activities are conducted in the well?

Types of well intervention

• Pumping.
• Wellhead and Christmas tree maintenance.
• Slickline.
• Braided line.
• Coiled tubing.
• Snubbing.
• Workover.
• Subsea well intervention.

Which of the following requires a well intervention?

Explanation: Shutting off flow from a high water cut interval requires Well Intervention and need immediate measures.

How long does it take to workover a well?

For most wells, it takes from one day to several weeks to perform a well completion, during which the flowback mixture is typically released to an open pit or tank where the gas released from the liquids is vented to the atmosphere or flared depending on regulatory requirements or other factors.

Which of the following requires a well intervention workover?

Explanation: Shutting off flow from a high water cut interval requires Well Intervention and need immediate measures. Workover is a well intervention process due to some problems faced. Basically, it is major maintenance or remedial treatments on an oil or gas well.

What is completing a well?

Well completion incorporates the steps taken to transform a drilled well into a producing one. These steps include casing, cementing, perforating, gravel packing and installing a production tree. After a well has been drilled, should the drilling fluids be removed, the well would eventually close in upon itself.

What equipment do we use in mechanical lwi?

During mechanical LWI, proprietary equipment and tool designs enable increased recovery while reducing costs in a wide range of subsea scenarios. We use fit-for-purpose wireline tractors, milling, and logging tools, and gauge rings to perform a wide range of tasks.

Why choose our hydraulic lwi system?

Our hydraulic LWI system enables you to achieve critical well stimulation objectives, effectively restoring or enhancing production from subsea wells. We use hydraulic actuation to access live wells and carry out prescribed acidization or other light intervention programs.

Who is involved in a lwi operation?

Each hydraulic or mechanical LWI operation is planned, deployed, and overseen by our experienced subsea engineers and technicians, downhole wireline engineers, and project managers. Our teams provide full-time site supervision and engage in close customer collaboration while adhering to rigorous QA/QC standards.
