Abstract
One of the most important elements in reserves calculation is the estimation of water saturation and its extrapolation away from the wells. Traditionally, workflows for water saturation interpretation for 3D geological models are based uniquely on water saturation measurements from log data using the Archie equation. These techniques although proven in several fields around the world, are heavily affected by the mineralogical content of the rock, porosity, permeability cementation, saturation exponents, etc. Two examples are shown in this paper. The methodology described in this paper uses capillary pressure data in conjunction with log data to reconcile the water saturation values both at the well locations and between them. The Leverett
