Drawdown Well Test Interpretation Using Pure Excel:

A No-Code Approach

This file outlines a method for interpreting drawdown well test data using Microsoft Excel exclusively. The approach involves solving the diffusivity equation in the Laplace domain and subsequently converting the solution to the real-time domain through the numerical Gaver-Shehfest algorithm.

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