LONDON — Serica Energy reduced carbon intensity at its Bruce production complex in the UK northern North Sea by 15% in the first half of this year, compared with the same period in 2021.

The year-to-date carbon intensity (emissions divided by production) is 16.5kg CO2/boe, reflecting efficiency measures and optimization of production throughput. And flare volumes are down by 23% compared to the same period last year, due to closer daily tracking and operational improvements.

Earlier this year, the company removed the residual section of a redundant caisson that caused a production outage in 2020, modified the platform compression system to support further production boosts from the Western Area Development (WAD) area and completed a light well intervention on two of the WAD wells.

Serica also restored the Bruce M1 well following a first reentry since 1998, which involved scale removal and water shutoff, reperforation and new perforation. Production rates from the well have since increased from about 400 boe/d to more than 1,800 boe/d.

Early next year, the company plans to replace the subsea control module in the Keith well (K1), a tieback to the Bruce complex, followed by a light well intervention to restore production from the well in late 2023/early 2024.
