b) The following data are given for the Sepat Oil Field: (7 marks)
Area =26,700 acres
Net productive thickness =49ft
Porosity =8%
Average Sw=45%
Initial reservoir pressure, pi =2980 psia
Abandonment pressure, pa =300 psia
Bo at pi =1.68 bb(l)/(S)TB
Bo at pa =1.15 bb(l)/(S)TB
Sg at pa =34%
Sor after water invasion =20%
Calculate Initial oil in place, oil in place after volumetric depletion to abandonment pressure and oil in place after water invasion at initial pressure. (10 marks)
