Overview

Challenges
  • Insufficient well history
  • No recent interventions on the well
  • Multiple services and providers required on a tight project timeline
Results
  • Delivered an integrated well abandonment solution that adhered to UK oil and gas guidelines
  • Completed the operation 3 days ahead of the 8-day schedule
  • Saved time with the WASP single-trip system
  • Saved 30% on daily rates by using an LWIV instead of a rig
  • Reduced footprint and costs by sharing equipment across vendor teams
Case study details

An operator working in the North Sea was abandoning one of their suspended wells, which required removing annuli well fluids and placing a final surface cement plug across all annuli prior to cutting and removing the wellhead.

After being contacted for a cost- effective solution to perform these plug and abandonment operations, Baker Hughes proposed the wellhead abandonment straddle packer (WASP) system, followed by an abrasive cutting tool to complete the operation from a light well intervention vessel (LWIV). This would provide the operator with large financial savings compared to a rig-based solution.
