Chichimene is the third most important field of Colombia. The estimated recovery factor was around 3%, and the reservoir pressure was declining drastically. Because of this, it was necessary to urgently implement an enhanced oil recovery project, since without immediate intervention, the reservoir and field production would be seriously affected.
A thorough screening process was performed among diverse EOR options. The research of an effective technology for the field-specific conditions and a low deployment cost indicated dumpflood as the best alternative, since it enabled injection from a deeper water formation to an upper production target zone through a smart BHA, substantially reducing injection facilities investment and operational costs. Time savings were identified, eliminating additional requirements for environmental permits. The main concern was that this technology has never been implemented for extra heavy oils.
Simulations in a steady state simulator validated the feasibility of the dumpflood technique in the field.
