Sweidieh Oil Field

Oil Field Development 

Purpose:
• Significantly increase in the Swedieh Oil Field liquid/oil production rate.
• Separation of oil from water and associated gases.

Overview:
• Liquid/oil collected from 150 oil production wells.
• Transportation via remote test stations (RTS) to oil gathering stations (GTS), capacity 20,000 m³/day (50 wells).
• Separate oil with 10 to 30% concentration from the associated formation water and gas and test 10 neighbouring wells.
• Three-phase, 2 stage, 3 gas/oil/water separation plants.
• Transmission pipelines.
• Massive water injection pump stations.
• Pipeline networks.

Separation Process:
• Stage I: Separated gas (suspension pressure 2 to 3 barg) is transported through gas pipelines to Sweidieh gas plant, while gas separated.
• Stage II: Separated gas (separation pressure 0.1 to 0.2 barg) is compressed and transported through the same gas pipeline to Sweidieh gas plant.
• Separated formation water is injected in to 60 injection wells, 20 wells for each GTS.
• Produced oil is transported through pipelines to Tel Addas Terminal Station.
• The GTS is supplied by electricity through two overhead lines from the exiting 20 kV distribution switchgear at the gas turbine power plant.
• The GTS units are secured by incorporating an emergency shutdown system.

Components:
• Three oil gathering and transportation stations (GTS).
• Remote test stations (RTS).
• Flow lines between wells and RTSs.
• Three main oil GTSs.
• Pipelines between RTS and related GTS to transport produced liquid/oil from RTSs to GTSs.
• Three pipelines between GTSs to Sweidieh gas plant to transport separated associated gas.
• Three pipelines from GTSs to Tel Addas Station to transport oil containing 10 to 20% water.
• 60 flow lines between GTSs injection manifolds to injection wells (20 W.I. wells for each GTS).

GTS Components:
• Well inlet manifolds.
• Vertical test separator.
• Bulk production horizontal three phase separators, Stage I.
• Bath water type heaters.
• Horizontal two phase separators, Stage II.
• Oil with 10 to 20% water shipping centrifugal pumps.
• Formation water settling con roof tank.
• Formation water pumps.
• Skimmed oil tank.
• Associated gas centrifugal compressors, electrically driven.
• Gas/oil/water wells flow lines and pipelines,
• Control and communication systems.
• Control building: Control rooms and offices.
• Two flare units.
• High- and low-pressure type.
• Chemical injection system.
• Fire protection system.
• Lake and drain system.
• Fence around each GTS.
• Rigging system.

Narrative Description:
The project was carefully designed to significantly increase the liquid/oil production rate from the massive formation in Sweidieh Oil Field.
State-of-the-art process, piping, corrosion, erosion, hydraulic, electrical, instrumentation control, telecommunications, civil and architectural engineering consultancy services were effectively delivered.
