Simulation study of improving oil recovery by polymer flooding in a Malaysian reservoir

This research is a simulation study to improve oil recovery using waterflooding and polymer flooding techniques based on data obtained from the Perdana oilfield in Malaysia and the Brillig reservoir as described in Eclipse 2000. There was no published report on polymer flooding project or polymer fl...
