Furthermore, history matching of reservoirs with significant periods of VRR < 1 (which are not uncommon due to unplanned...

... permeability (k ro ) during different gas injection cycles, for both water-wet and mixed-wet rocks. However, a considerable cyclic hysteresis effect in k ro is observed during water injection cycles of WAG, which is attributed to the reduction of the residual oil saturation during successive water injections...

... petrophysical surveillance has been restricted due to limited well access and logistical challenges. During the infill drilling, it was therefore decided to use the opportunity and capture cased-hole saturation and production logs in existing wells. This data enabled the asset teams to understand fluid...
