Meta successfully completes two jobs in the North Sea
The Meta Casing Reconnect™ has been successfully used on two projects in the North Sea.
Gas lift conversion
The first job involved an operator’s well which was to be converted to gas lift to maintain efficient production. However, a leak in the well meant it was not possible to convert to gas lift and production was stopped.
The operator required existing production casing to be cut and pulled, a change out of the wellhead seals, the casing to be re-established with a deeper crossover, and a non-elastomeric VO seal established, leaving the 9-5/8 casing in tension.
Using Meta’s patented Metalmorphology™ technology, the casing reconnect met these requirements, providing a life of well metal-to-metal solution with flexible space-out and no reduction in ID.
The Meta Casing Reconnect ensured double barrier, V0 integrity allowing recovery of up to 200 m3/d oil production. The operation also allowed recompletion with larger production tubing and the change-out of a leaking downhole safety valve.
Casing hanger damage
On the second project, the operator faced casing hanger damage due to previous milling operations in one of its wells.
As a result, the casing needed to be cut below the wellhead, the existing casing hanger pulled out, and a new hanger reinstated, whilst ensuring a V0 gas-tight seal for the life of the well.
The existing casing was cut and reconnected to the new wellhead using Meta’s Casing Reconnect by morphing the new casing to the existing casing of the same ID. A permanent, metal-to-metal, gas-tight, and axial loading bearing connection was created, providing full integrity and regaining full access to the well.
Kevin Stewart, CEO of Meta said: “These projects demonstrate how Meta is able to assist operators in recovering from downhole challenges while also adding value to their operations. This was evident through our rapid response and the application of our award winning, metal-to-metal, in-situ sealing technology”.
