Case Study

Summary

Re-establishing the integrity of the annulus is usually complex and may require a full workover operation. We engineered an innovative rigless solution to remediate the failed annular cement which located at approx. 2000 m deep. The designed ThermaSet^® resin was gravity fed into the B-annulus from the surface. Well-planning, testing, and simulations prior to the job execution resulted in re-establishing the integrity of annulus, and dramatically reduced operational costs.

Below, you get more insight into this case. You may also download your free copy of the case study, which also includes details about how Wellcem implemented the solution and most importantly - the results achieved for the operator company.

The customers' options

• Workover (pull the completion, perforate casing, then squeeze cement into the annulus)
• Resins

Why did they choose to cooperate with Wellcem?

• The unique properties of ThermaSet^® resin allows it to be gravity fed thousands of meters.
• ThermaSet^® resin has been successfully used to re-establish the integrity of annuli in over 400 wells.
