Global well integrity and production optimisation firm, Coretrax, has created a casing integrity solution for a major North Sea operator which is said to eliminate the need for a casing string to be replaced.
The project saw a team of three engineers identify and mobilise the trouble zone, and install a short patch on a casing section of the well affected by corrosion.
To pinpoint the trouble zone, the engineers deployed its CX-RTP (retrievable test packer), a heavy-duty service packer used to set and pressure test a range of depths to identify the area in need of patching.
Following the identification of the trouble zone, the company deployed its ReLine HYD expandable casing patch to isolate the area and regain well integrity without the costs associated with replacing the casting.
Western Hemisphere President at Coretrax, Keith Bradford, said, “Our team of engineers worked collaboratively to identify how we could combine technologies from across our portfolio to effectively meet our client’s objectives. We mobilise products from CORE, our expandable tubular product line, and packers from our AEON line which we use for plug and abandonment solutions.
“The outcome was a great success and allowed our client to not only continue operations with minimal disruption or downtime, but also potentially saved costs on replacing the entire casing string.”
The project was completed in five days.
