The National Institute for Petroleum and Energy Research (Niper) is conducting reserach to develop improved methods for oil recovery by immiscible CO/sub 2/ displacement. The research includes fundamental studies of displacement mechanisms and coreflooding tests for development of an optimal injection method. Heavy oils are the major target of this research. For heavier crudes (API gravity below 25/sup 0/), high viscosity is a major constraint in oil recovery and pipeline transportation. Therefore, reducing oil viscosity becomes critical. Methods currently being used for viscous oil recovery include thermal methods (steamflooding and in situ combustion) and CO/sub 2/ methods. Steamflooding has been widely applied. The number of immiscible CO/sub 2/ projects is small but increasing.
