This spreadsheet helps users grasp the methodology for solving the diffusivity equation in the Laplace domain and converting the solution to real-time using the numerical Gaver-Shehfest algorithm.

It’s not a PTA tool; instead, it’s designed to help users understand the process behind PTA interpretation. By manually adjusting parameters like skin and kh, users can observe their impact on the log-log plot.

The interpretation focuses on early-time wellbore storage, skin effects, and infinite-acting radial flow (IARF) behavior.
