Despite its challenges, targeting recoveries of up to 70% is possible but requires a long-term perspective and a step change in the way we think about field developments.
Traditional approaches focus on EUR per well optimisation rather than total field recovery and determining a field’s optimal well spacing early on could significantly lower overall development costs in the future. Likewise, early identification of a field’s future EOR potential is important as it may guide early design considerations, such as materials selection and avoid unnecessary expenditures down the line. Since one solution is often not applicable across a given field, piloting different EOR schemes may also be required.
Down spacing coupled with 4D seismic to chase unswept volumes is a simple means of increasing total recovery, however in practice this approach is often underutilised. Recent advances in gas injection (CO₂) and chemical EOR also have merit and their applicability should be evaluated.
In order to overcome the challenges associated with achieving higher recovery targets, the industry will need to implement a step change in the way it thinks about full life cycle developments and encourage increased levels of knowledge transfer, data sharing and collaboration. This workshop will continue to pave the way towards this goal.
