The Teekay-owned cylindrical platform has operated on the field since 2008, producing more than 13 MMbbl of oil. Current output is around 7,000 b/d.
Chestnut was originally expected to deliver no more than 7 MMbbl over three years. However, Centrica’s studies suggest a total of 18 MMbbl can be recovered via a water injection side track well, sustaining high production efficiency and continued work with the company’s partners Dana Petroleum and Atlantic Petroleum; Teekay; and duty holder Wood Group PSN.
Hummingbird Spirit can store more than 200,000 bbl of oil. Flexible risers take oil from two production wells and water to the single injection well.
