Batl Raman oil field, with its 1.85×109 STB oil in place and poor primary recovery (1.5% of IOIP) was a good target for enhanced oil recovery.

As a result of extensive laboratory, modeling and comparative engineering studies, TPAO has decided that an immiscible type CO2 application would be the most suitable method to enhance the recovery from the field.

Initially planned "huff and puff" has now turned to a successfull CO2 flood.

Around 2×106 STB of incremental oil have been produced, since the project resumed continous operation in late 1986. With daily production increase reaching over 4000 STB, and still having an increasing trend, the project looks promising.
