Case study / Land asset, Niger Delta
BRINGING LEGACY POTENTIAL INTO PRODUCTION.
The programme combined re-entry planning for a 1979 legacy well with new-well drilling and dual-string completions to access multiple reservoir zones.
THE ENGINEERING CHALLENGE
Legacy well uncertainty, sand production risk, dual-zone integrity and multi-vendor interfaces required a coordinated technical and execution plan.
- Re-entry assessment with documented contingencies
- Formation-tailored gravel pack design and installation QA/QC
- Long-string and short-string completion architecture
- Drilling-on-paper alignment and coordinated SLB / Weatherford execution
THE OUTCOME
Successful delivery across both completion strings, with multi-zone reservoir access and controlled sand production.
