Comparison of Well Testing and Production Data Analysis for Estimating Reservoir Parameters

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.
