Enhanced oil recovery from heavy oil reservoirs utilizing a displacement agent

  • Published:
Chemistry and Technology of Fuels and Oils Aims and scope

An oil displacement agent consisting of nonionic and anionic surfactants and emulsion stabilizers has been developed to enhance oil recovery from heavy oil reservoirs. The experimental results show that the proposed displacement agent enhances oil recovery by more than 20 % compared with water flooding and that the emulsion contained in the fluid produced can be easily broken (demulsified). The mechanism of action for the displacement agent is described.
