Q1 A well is producing under reservoir pressure maintenance project. The reservoir pressure is (5,000+ Last 3 digits ID) psi and the minimum possible wellbore pressure is 3,300 psi. Given following data available: Reservoir length. L = 10000 ft Reservoir Width = 1000 ft Oil formation volume factor, B = 1.5 bb1/STB Permeability, k = 150 md Porosity = 20% Oil viscosity, u = 3 cp Reservoir thickness, h = 30 f. (a) Determine: i. Well flow rate under these conditions (steady-state linear flow) (2 marks) ii. Well flow rate when Ho = 3.5 and 5 cp iii. Well flow rate when Ho = 2.5 and 1 cp (2 marks) (2 marks) Analyse your results in (a)(ii) and (a)(iii). (4 mark)
