This paper is an update to an earlier submission1 and presents the current status and progress of several main EOR projects in Malaysia.
As of January 2005, the estimated oil-in-place from producing fields in Malaysia stands at about 17.0 Bstb2 , with estimated ultimate recovery (EUR) of 5.62 Bstb. This translates to an averaged recovery factor of only 33.0 percent for producing fields in Malaysia. PETRONAS had realized the importance to further increase the recovery factor and so far has been pursuing EOR implementation in its fields aggressively. To date, a full-field WAG application in Dulang field3,4 is already at its final stages of implementation. In addition, EOR projects have also been planned for another ten fields i.e. Tabu, Tapis, Guntong, Tiong/Kepong and Angsi in Peninsular Malaysia and Baronia, West Lutong, St. Joseph, Bokor and Baram in East Malaysia.
Each of the project is currently at different level of maturity and some preliminary results for five selected EOR projects that are in the late stages of study or in the pilot phase; namely in Dulang3,4 , Tabu, Baronia, West Lutong5 and Tapis6 fields will be discussed in this paper.
