Two appraisal wells complete; evaluation and concept selection continue

Participation source

NEP reports its BC39-1 and BC37-1 appraisal wells complete across CS006 and CS007. The results inform expansion capacity and scope ahead of concept selection, planned 2027 FEED and a planned 2028 investment decision.

Project anatomy

Contract scope and delivery roles

Client / authority
Net Zero North Sea Storage Limited, trading as Northern Endurance Partnership
Delivery parties
NEP directs the appraisal and evaluation programme; the cited completion announcement does not identify the drilling contractor.
Contract route
The owner describes completed appraisal and future evaluation, concept selection, FEED and investment decision. A current supplier competition is not identified in the cited records.
Execution window
Appraisal completion was reported on 27 October 2026. Evaluation continues through 2026-27; FEED is planned for 2027 after concept selection, with FID planned for 2028.
Works package
Appraisal wells C43/30-2 (BC39-1) and C44/27-3 (BC37-1), geophysical surveys, environmental assessment and offshore studies. The March concept expects four CS006 injection wells and three CS007 wells, subject to appraisal and further investment.
Marine interfaces
Injection duties and pressure cases drive the operating requirements of subsea wells, manifolds and connecting pipelines. The March development concept links CS006 to Endurance and identifies the expected injection-well configuration for each expansion system.
Commercial evidence boundary
The work defines the future installation scope. Completed appraisal supplies new subsurface information, while the planned 2027 FEED and 2028 investment decision control the subsequent engineering and construction commitments.

Evidence gap

What remains unverified

Outstanding evidence

  • Combined appraisal interpretation and selected expansion configuration
  • Injection duties, operating pressures and subsea connection scope
  • Concept-selection outcome,2027 FEED and 2028 investment decision
