Abstract

Abstract: The microbial enhanced oil recovery (MEOR) technique is applied to Ansai oil field of extra-low permeability for EOR. Following experimental study and evaluation of the rational injection project, a pilot test is conducted. The successful result shows that the previous raising water cut has been controlled and the composite production decline rate has been decreased, allowing it to be a successful case in this field by MEOR process.

Key words: Ansai oil field, low permeability reservoir, MEOR, pilot test
