Serica Energy connects third Rhum well for production

Serica Energy PLC has connected well R3 to subsea production infrastructure in Rhum field after recompletion and a successful flow test. The field is in the UK Northern North Sea, about 380 km northeast of Aberdeen in water depth of 109 m.

The work program involved recovering equipment left in the well by the previous operator and removing an obstruction that was across parts of the downhole completion (OGJ Online, Oct. 12, 2020). After installing new completion equipment, a stabilized flow rate of 58.4 mmscfd gas and 135 b/d condensate was achieved through a 60/64-in. choke. This rate was constrained by the surface well test equipment on board the WilPhoenix semi-submersible drilling rig. It is expected that the well will be able to produce at higher rates when in production.

A diving support vessel has been contracted to install the subsea control equipment required so the well can start producing in third-quarter 2021.

The successful recompletion of R3 will increase the Rhum production capacity via existing Bruce platform infrastructure. It will not significantly add to CO₂ emissions. This is in line with Serica’s stated objective of reducing the carbon intensity of its production operations.

Serica is operator at Rhum (50%) with partner National Iranian Oil Co. (50%).
