GasWell Optimization GasWell is an easy to use package used for optimizing the performance of a gas well. Sandface inflow, tubing performance and wellhead conditions are used to maximize production. With this package the user can investigate the flow improvement after stimulation, increasing the wellbore, and lowering wellhead pressure. Up to six different wellbore sizes can be investigated in one run.
