Meta Casing Reconnect Delivers for Norwegian North Sea Operator

As a supplier of Meta downhole products we’re pleased to pass on good news stories. The below case study demonstrates how Meta’s Casing Reconnect system enabled a North Sea operator to re-establish casing to the subsea wellhead and avoid running a costly and time consuming sidetrack, saving around $3 million in the process.

The Operator’s Challenge

The operator’s well was a new-drill water injector, with drilling commencing in late 2014. However, while running the 13 3/8” Q125 casing section they were unable to land and set in the hanger and cemented the casing string high. They cut and pulled the 13 3/8” casing at 570m and temporarily suspended the well while they considered their options, while the rig went into dock for upgrades.

The ideal solution was to re-establish their 13 3/8” Q125 casing and therefore avoid running a sidetrack. 

The Meta Casing Reconnect Solution

Using the Meta Casing Reconnect system, the operator was able to reinstate the 13 3/8” Q125 casing with full integrity and no reduction in ID, and avoid running a whipstock and sidetrack. The Reconnect system was deployed and morphed on drillpipe from the semi-submersible drilling rig.

The existing Q125 casing was cut and reconnected to the subsea wellhead by morphing the casing, therefore maintaining full ID. Following the morphing process, the tools were recovered and the well successfully pressure tested.

Within two days, Meta had provided a permanent, metal-to-metal, gas-tight, and axial loading bearing connection with full integrity and ID, enabling drilling to continue as originally planned. The client saved in excess of $3 million and avoided a costly 10-day sidetrack.
