Sensitivity of Oil Production to Petrophysical Heterogeneities
The multi-partner Saigup project was established to systematically investigate the relative importance of key geological heterogeneities on simulated production. In order to investigate the impact of the geostatistical variability, the petrophysical fields were drawn repeatably, and the variogram directions were rotated. The heterogeneities caused by the geostatistical variability in the petrophysical simulations and the variogram rotation were similar, and had a low impact on all the production responses except total water injected. Here they contributed about 20% of the total variability.
