Shell invests in US Gulf deepwater field to extend TLP production life
An oil major has taken the final investment decision on a waterflood project on a deepwater oilfield in the Gulf of Mexico (Gulf of America) to increase output through the Ursa platform
Shell has made its final investment decision (FID) on a waterflood project at its 100%-owned Kaikias field.
Subsea flowlines, risers, umbilicals and water injection systems will be installed on the seabed to increase production from the deepwater field, which is linked to the nearby Ursa tension-leg platform (TLP).
Shell said water will be injected into the Kaikias field to displace additional oil in the reservoir formation, sweeping the displaced oil to adjacent production wells, while repressurising the reservoir, with injection anticipated to commence in 2028.
This additional oil, estimated to be around 60M barrels, aims to extend the production lifecycle of the Ursa TLP by several years.
"Following our decision to increase our stake in Ursa in February 2025, this additional investment continues to maximise the value of the asset," said Shell upstream president Peter Costello.
"It also contributes to our aim of maximising high-margin production and longevity in a core basin to maintain liquids production."
Shell is the operator of the Ursa TLP and holds 61.3% ownership in the asset with BP Exploration & Production having 22.7% and Esperanza Capital Partners owning 16.0%.
Kaikias was discovered in August 2014 in 1,220 m of water, 209 km off the coast of Louisiana.
Along with Ursa, it is in the Mars basin in the Mississippi Canyon area of the US Gulf.
