Abstract

We need to know saturation dependent relative permeability and capillary pressure functions for the reservoir rocks in order to be able to carry out flow simulation successfully. Both of these properties depend on the wettability, which is acknowledged as playing an important role in fluid flow. We have carried out a sensitivity study of the two-phase flow properties on the production from a turbidite field, starting with network modelling to simulate two-phase flow at the pore scale. A new method has been used to "anchor" network model parameters to existing (drainage) capillary pressure curves. The wettability was varied systematically, and a range of corresponding relative permeability and capillary pressure curves were generated. These curves were then used in flow simulations of a sector of the turbidite reservoir. Results show that it is very important to consider uncertainties in the two-phase flow parameters because they have a significant effect on recovery.
