The deepwater challenges we confront is the continuous reduction in costs and cycle time to first oil or gas for field development infrastructure above the mud line in locations that are progressively deeper and more remote.
In a recent survey, operators with extensive deepwater portfolios identified field development system selection, project execution, technology development, and quality teams as critical success factors for profitable development. An underlying premise was that there was to be no compromise in health, safety, and environment, or in effective management of risk.
Reducing costs in ultra-deepwater will require technology development. It is important to focus on those technology's that will provide the biggest bang for the buck. System and value engineering processes have identified high impact technologies. Not surprisingly, subsea and downhole technologies offer greatest opportunities for increasing recovery, operability, and extending tieback distances.
- Unconsolidated sands are common among deepwater reservoirs in West Africa. Unconsolidated sands require sand control for completion and divers flow assurance
- Tight pore-pressure fracture gradient windows can create well stability problems
- Reservoirs in West Africa are naturally heterogeneous. Channel fill sequences are also existing in some areas
- Geography and infrastructure limitations can be challenging
- Flow Assurance mitigation and remediation more
- Geologic “Static” modeling
- Stimulation / Geomechanics modeling
(near-wellbore damage removal such as acidizing, water and gas conformance solutions, scale removal and prevention)
- Project Management more
