Serica Energy PLC contracted Awilco Drilling’s WilPhoenix for intervention of Rhum-3 (R3) in Block 3/29a, northern North Sea.
The work will recover debris left in the well by the previous operator and remove an obstruction believed to be across parts of the downhole completion. The well will be recompleted and put into production. R3 is already connected to the subsea production infrastructure.
Rhum is a gas condensate field producing from two subsea wells, R1 and R2, tied into the Bruce facilities through a 45 km pipeline. Rhum production is separated into gas and condensate and exported to St. Fergus and Grangemouth, respectively, along with Bruce and Keith production (OGJ Online, Nov. 30, 2018). The wells are capable of producing at combined rates approaching 30,000 boe/d (gross), of which over 95% is gas. The field has produced at relatively constant rates with limited reservoir decline evident through the past year. Average production in 2019 was 13,775 boe/d net to Serica.
WilPhoenix is a 3rd-generation, enhanced pacesetter, harsh-environment, mid-water, semi-submersible drilling rig. Operations are expected to begin in this year’s fourth quarter and last 70 days.
Serica is partner and operator at Rhum (50%) with Iranian Oil Co. (UK) Ltd. (50%).
