Project Profile
Location: blocks 23/26a (Area B) and 23/26b (Area B), UK Central North Sea, UK
Reserves: approximately 3.6 mmboe
Production (average gross): 10,092 boepd
The Erskine Field is a producing gas and gas condensate field operated by Chevron and is estimated to have remaining reserves of approximately 3.6 mmboe. Average daily gross production during Q1 2014, after which production was suspended for infrastructure maintenance, was 10,092 boepd. The field, located in blocks 23/26a (Area B) and 23/26b (Area B) recommenced production on 10 June. Fluids from the field are transported from the Erskine platform (a normally unmanned wellhead platform) to the Lomond platform where they are processed and gas is delivered via the CATS pipeline system to the terminal at Teeside. 60% of the gas is purchased by SSE on formula contract prices and 40% is sold in the market at spot prices. The condensate separated at the Lomond platform is delivered via the Forties pipeline to Cruden Bay. The Erskine field produces through the Lomond facilities which lie close to the Columbus field.
Production from the Erskine field is currently subject to inefficiencies in the transportation and processing plant downstream of the Erskine platform, particularly at the Lomond platform. Work is currently in hand to improve production efficiency which will require a shut down for scheduled maintenance between end October 2014 and end February 2015. The Erskine field is capable of significantly improved production performance if these current efforts to improve efficiencies are successful.
