Company/Alliance: Saudi Aramco
Location: Saudi Arabia
Start Date: Operational 2015
Size: 0.8 Mt/yr
CO2 Source: Hawiyah gas plant
Transportation: 85 Km onshore pipeline
Oil Field EOR Storage Site: Ghawar field
Injection Depth: N/A
Reservoir Type: Jurassic Carbonate limestones
The objectives of the project are determination of incremental oil recovery (beyond water flooding), estimation of sequestered CO2, addressing the risks and uncertainties involved (including migration of CO2 within the reservoir), and identifying operational concerns. Specific CO2 monitoring objectives include developing a clear assessment of the CO2 potential (for both EOR and overall storage) and testing new technologies for CO2 monitoring.
Approximately 60–65% of all Saudi oil produced between 1948 and 2000 came from Ghawar. Cumulative production until April 2010 has exceeded 65 billion barrels. It was estimated that Ghawar produced about 5 million barrels of oil a day (6.25% of global production) in 2009. Ghawar also produces approximately 2 billion cubic feet of natural gas per day.
After 60 years of production, the field is depleted and Saudi Aramco is going to start CO2-EOR. The project will consist of 4 injection wells, 2 observation wells and 4 productions wells. The project is expected to last 3 to 5 years, during which Saudi Aramco will apply any lessons learnt to other facilities and fields around Saudi Arabia.
