Enhancing Oil Production By Resolving Water Cut Issues
Project : EPF 6P HARASH
Field : GIALO 59
Client : WAHA OIL COMPANY
CLIENT PROBLEM STATEMENT
- One of the main challenges faced in the wells (6P-1& 6P-3) was the high Water Cut percentage. As we know the water cut effect to facility & environmental therefore reducing the Water Cut can improves oil quality.
- It also lowers processing costs by minimizing the effort required for separation. Additionally, it protects equipment from corrosion and damage, extending its operational lifespan. Finally, it boosts production and profits by enhancing efficiency and reducing losses.
- For these reasons, work was done to reduce the water rate from 22 % to 4%. flowed into the storage tanks and increase the settling time, causing contamination of the crude oil output with excess water in the drain line.
Challenges
- The Demulsifier was injected at the Separator inlet, which did not allow sufficient time for proper separation inside the vessel.
- The Separator outlet was directly connected to the storage tanks’, leading to mixing of separated water with the crude oil during the drain process.
- There is not drain system at offloading station.
ALFANOIL Solution
- Relocating the chemical to the Wellhead, allowing more time for the separation process before entering the Separator.
- Used the Storge tanks in offloading station as settling tanks that install the draining system at end of series tanks that using as second stage separation
