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. Cunnilative gas produced versus time 4. Cunmulative oil recovery versus reservoir pressure 5. What is the fractional oil recovery at abandonment condition? 6.
