LONDON – Serica Energy has issued an update on its UK North Sea activities, including the Bruce field and associated satellites, which it acquired from BP.
Following successful campaigns last year to repair three conductors at the Bruce complex, four more sets of conductor clamps were installed during August to safeguard against future well shut-ins.
A diving campaign successfully reinstated a second umbilical to the WAD manifold, thereby increasing reliability from the subsea wells.
Serica has conducted a successful trial of lower pressures at the wellheads to facilitate increased gas production. The company also re-commissioned the test separator on the compression platform, increasing the capability to undertake well performance tests.
In addition, it undertook a well by well review to identify production upsides achievable from planned well intervention campaigns.
The R3 well on the Rhum satellite requires intervention before it can be restored to production, but as output from the R1 and R2 wells has been higher than anticipated, there is less processing capacity available at Bruce for additional volumes from R3.
Work on this well will now be deferred to late 2020 or early 2021.
Further works have continued on the Erskine production module on the Lomond platform to rectify a long-standing compressor seal issue.
Regular pigging has continued on the replacement Erskine pipeline, with no indications so far of wax build-up.
