Numerous wireline and coiled tubing runs performed in the oil producing well, Snorre P-38, caused damage in the nipple seal area of the DHSV. This fault made the implementation of other known cost-effective solutions to be unsuccessful.
The Insert DHSV Carrier (IDHSV) previously tested at BTU facilities (ISO14310/V1), along with a 5½” insert safety valve, was successfully installed and tested to full operating pressure in the P-38 well, using the existing safety valve profile to appropriately set the insert safety valve and straddling the existing hydraulic mechanism.
This successful project, which avoided a costly and lengthy workover, displays an excellent solution for wells that present corrosion or mechanical wear in their existing DHSV systems.
