Extracted text: The reservoir capillary pressure-saturation data of the Angsi Oil reservoir is shown graphically in Figure 1. Geophysical log interpretations and core analysis establish the OWC at 3190 ft. The following additional data are available: - Oil density = 43.5 lb/ft Water density = 64.1 lb/ft Interfacial tension = 50 dynes/cm Calculate: a) Connate water saturation (Swe) %. b) Depth to FWL, ft. c) Thickness of the transition zone, ft. d) Depth to reach 50% water saturation, ft. 12 10 Pc psi 0.1 02 03 0.4 0.5 0.6 0.8 0.9 SW Figure 1: Capillary pressure saturation data. 21
