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.
