Gas Buildup Analysis

GasBU uses standard buildup tests from individual wells and performs a buildup analysis using various methods. The program allows for easy determination of Reservoir Permeability, and Skin Effect using graphical and numerical

analysis. Results are summarised by well, group, pool, lease and company.
