Improving recovery through miscible displacement EOR has been known to be technically feasible for many years and the underlying principles are well understood. Depending on the properties of the reservoir and the injected gas an increase in recovery of up to 15% can be expected.
Nevertheless for a variety of reasons EOR projects can be daunting to embark on;
The reservoir engineers must use compositional modelling techniques which are more time consuming, expensive and less familiar.
However with so many giant fields approaching the end of field life and pressure mounting for operators to adopt a zero emissions policy it is virtually a given that most operators will have to at least investigate the EOR potential of their reserves at some point in the near future.
Ingen staff has participated in a number of potential EOR development screening exercises, providing commercial and technical support. As such we have a unique understanding of the difficulties of converting a technically feasible project into an economically successful project.
Given the current state of technology and the lack of carbon credits the most common blocker for EOR projects is either the capture cost of CO2 or the lack of rich natural gas. As such, at the moment some geographical locations are simply more suited for EOR projects, than others.
