Oil Field Reservoir Optimisation Project

- Project was completed for an offshore oil field with Cretaceous sandstone reservoirs.
- Compared production rates with budget and proposed operating efficiency improvements.
- Developed well utility review documents for all production and water injection wells.
- Created reservoir management plan documentation.
- Completed SWOT analysis and evaluated production history by well.
- Completed formation pressure and field connectivity assessments
- Used RFT pressures, liquid rates, GOR and water cut to deduce weak aquifer, and concluded that water injection was the dominant reservoir drive mechanism.
- Evaluated impact of geology on reservoir and well performance.
- Evaluated BHP and THP pressures for well performance, tubing restriction, etc.
- Completed reservoir voidage analysis and optimised water injection rates.
- Constructed Saphir well test models and estimated skin and permeability thickness variations over time.
- Monitored sand production trends, and preserved well integrity and oil production.
- Stewarded water injection trials to evaluate connectivity with producers.
- Evaluated impact of water injection on reservoir and well performance.
- Used RFT pressures and water chemistry to deduce water source.
- Secured endorsement of a new production service pipeline and a new methanol umbilical, and preserved 18 MMUSD NPV.
