Saudi Arabia: Ghawar
Ghawar is the largest conventional oil field (see map below) in the world, and core to the oil production strategy of Saudi Arabia, but it is also well past its peak production phase.  Based on our simulation model of Ghawar, and a close comparison with nearby analogous fields, it is our assessment that Ghawar is close to going on decline, if not already there. Update:  the recent bond prospectus prepared by Saudi Aramco confirms the above assessment.

From the Saudi Aramco Bond Prospectus
"The northern-most portion of the Ghawar field lies approximately 100 kilometres west of Dhahran. The field
comprises six main areas (Fazran, Ain Dar, Shedgum, Uthaminyah, Hawiyah and Haradh) and extends southward
over more than 200 kilometres as one long continuous anticline. It is approximately 36 kilometres across at its
widest point (where the Ain Dar and Shedgum areas run in parallel and are 26 kilometres and 10 kilometres
wide, respectively).  The Company believes that the Ghawar field is the largest oil field in the world in terms of conventional proved
reserves, totalling 58.32 billion barrels of oil equivalent as at 31 December 2018, including 48.25 billion barrels
of liquids reserves. It has accounted for more than half of the total cumulative crude oil production in the
Kingdom but still maintained a MSC* of 3.800 million barrels of crude oil per day as at 31 December 2018."

* MSC refers to the average maximum number of barrels per day of crude oil that can be produced for one year during any future
planning period, after taking into account all planned capital expenditures and maintenance, repair and operating
costs, and after being given three months to make operational adjustments.

Part of what is missing from this discussion is how much of the remaining estimated recovery will require some type of EOR?  The reason we ask this question is that based on our analysis and on numbers provided by Aramco in the bond prospectus, we estimate the EUR for oil from Ghawar will be approximately 128 billion barrels.  Our estimate for OOIP is approximately 170 billion barrels, indicating an ultimate recovery approaching 75%, which seems unrealistic in a reasonable time frame unless there are extensive and expensive EOR operations contemplated for Ghawar in the not too distant future.  Also, when we compare Ghawar to directly analogous fields, the potential for achieving such recovery levels seems unlikely without the aforementioned EOR operations.

 

If interested in our projection of the future production performance of Ghawar, as well as discussing our simulation model and the production performance from nearby, analog fields, please contact us at insight@energy-cg.com.
