Confirming and optimizing the water flood
The survey geometry involved running the DeepLook-EM service tools in
two observer wells relative to an existing injector well. The close well
spacing provided a high-resolution view for monitoring.
A model of the reservoir was constructed from conventional wireline
resistivity measurements made before injection. From this baseline, the
time-lapse analysis of DeepLook-EM service's resistivity imaging over a year of
water flooding indicated successful movement of a large volume of swept water,
which was consistent with the injection volumes and production results. The
results also suggest that there could be remaining oil to be produced, and the
injection strategy can now be optimized to extract the bypassed pay.
