​

Saturation Height Modelling from capillary pressure measurements helps quantify the hydrocarbon volume based upon the porosity and permeability of the reservoir. It should be reconciled with the traditional resistivity based saturation. The attached PDF presentation shows how this was in the Io-Jansz Field offshore North West Shelf Western Australia.

​

In addition the Io-Jansz presentation shows how a Imbibition Saturation Height Function can be applied to determine the residual volumes as the water aquifer has imbibed into the reservoir after production. This has never been captured before.
