Question \#2 (abet criteria A, E) The reservoir, PVT and relative permeability data are the same as given in Question \# 1 . Predict the reservoir performance using Tarner\&Tracy method. Show sample calculations at the first pressure below pi and the fourth pressure below pb. Compare the results obtained from Tarner\&Tracy's and Muskat's methods. The data given below pertain to an under-saturated oil reservoir. Initial reservoir pressure =2400psig Bubble point pressure =1800 psig Initial water saturation =0.20 Original oil in place =100106STB Water compressibility =3.0106psi1 Rock compressibility =4.0106psi1 The reservoir will be produced at a constant oil rate of 15,000STB/D using solution gas drive mechanism. The economic limit is when the reservoir pressure drops to 400psig or the instantaneous producing gas oil ratio exceeds 10,000 SCF/STB. Predict the reservoir performance using Muskat method and present your results by plotting the following : 1. Reservoir pressure versus time 2. Instantaneous gas-oil ratio versus time 3. Cumulative gas produced versus time 4. Cumulative oil recovery versus reservoir pressure 5. What is the fractional oil recovery at abandonment condition
