Harbour Energy and its partners are closing in on project sanctions across the Americas, with approval of the Who Dat East development expected this month in the US Gulf and further progress on projects in Mexico and the North Sea.

US Gulf developments move toward sanction

Harbour Energy and its partners expect to approve the Who Dat East development in the US Gulf this month, the company revealed in a results update.

Another final investment decision (FID) could follow by year-end on the LLOG-operated Salamanca FPS subsea pump project, designed to accelerate reserves recovery from Leon-Castile.

Who Dat East is an expansion of the existing Who Dat Field development in the Mississippi Canyon, while the Salamanca FPS project is designed to enhance recovery from the Leon-Castile area in the deepwater US Gulf.

During the second quarter, the company acquired new ocean-bottom node seismic data over its acreage in Keathley Canyon and Green Canyon.

Other highlights included startup of the Leon-1 well, supporting the ramp-up of production from the Leon-Castile hub; a fifth well at Buckskin, where results have surpassed expectations; and a sidetrack at Who Dat, which came online last month.

Activity will accelerate, Harbour added, with further drilling planned across Who Dat, Buckskin, Leon-Castile and Taggart. A second rig is due to arrive in late September and will likely drill an exploration well at Kingsroad.

Mexico projects advance toward FEED and FID readiness

Work continues on optimizing the development concepts for the shallow-water Zama and Kan oil fields. Harbour expects to issue invitations to tender this month for the major Zama FEED packages, including those related to the FPSO.

Both projects should reach FID-readiness by the end of 2027.

North Sea tiebacks and CCS projects progress

Offshore Norway, Harbour expects to spud two more exploration wells this year. In the UK central North Sea, the company is aiming for FID of the two-well tieback of the Fotla discovery, recently acquired from Ithaca Energy, to Harbour’s operated Greater Britannia hub.

A further tieback development of the Leverett Field to the same hub should follow Fotla.

Finally, the company expects commercial operations to begin shortly from the Greensand Future carbon capture and storage project in the Danish North Sea, with a CO₂ injection rate of 400,000 metric tons/year.

The UK government has approved £65.5 million (US$88.17 million) of funding for the Harbour-operated Viking CCS project offshore/onshore eastern England to support further technical and commercial work, ahead of a potential FID.
