You are the reservoir engineer responsible for an oil well flowing at a rate of 50 stb/d. The field operator gives you the data shown in the table below measured with a downhole pressure gauge. (a) What is the flow regime of this well (transient, steady state, pseudo steady state) and why. (b) Calculate the drainage area of this well in acres. (c) What is the average reservoir pressure at each time step in the table (d) What is the expected downhole flowing pressure at 12 months assuming constant flow rate can be maintained. Use average reservoir pressure for your calculation. The following additional data are available: Bo = Ct = 1.1 rb/stb 1.60E-05 1/psi porosity = 0.3 h = 158 ft rw = 0.3 ft Oil Viscosity = 2.68 cp Permeability= 1.2 Md Wellbore Time (months) Pressure (psi)l 3500 3. 3285 6. 3070 9 2855
