This project studies on the applicability of the Pressure Transient Analysis (PTA) and Rate Transient Analysis (RTA) in estimating reservoir parameters. Reservoir parameters refer to the characteristics of the reservoir to store hydrocarbons and produce them, such as permeability and skin factor. Both PTA and RTA are independent of each other as PTA make use of Pressure-Time data and RTA make use of Rate-Time data in their analysis. However, the derivation of the equations for both PTA and RTA are actually based on the application of diffusivity equation. In this project, both PTA and RTA are applied to analyze the pressure-time data and flow rate-time data obtained from the same well. The results yield by these two methods are then compared and analyzed. It is found that these two methods yield reasonably closed estimation of the reservoir parameters of the same well.
