Assessment ofl-WAG for Optimnm Recovery from a Heterogeneons Reservoir Offshore Terenggann, Malaysia.

\Vater alternating gas, \VAG seems to be the most practical EOR for Malaysian fields considering the abundance of C02 gas and the availability of treated seawater for injection. The injected seawater is used to increase the macroscopic displacement whereas the injected C02 gas is used to mobilize...
