How perforation shot density affects gas well performance

OSTI ID:7104329

The single gas well model is formulated using the systems analysis approach and is composed of three main modules. The first module is the modified inflow performance relationship (IPR). This IPR accounts for pressure drops through the reservoir, laminar skin and damaged, compacted zone around casing perforations. The second module is the tubing outflow performance computed via the Cullender and Smith method. The third module is the gas material balance equation for computing average well pressure with a given gas production level. By coupling this equation with the computed inflow and outflow results, future gas deliverability and economic return of a gas well can then be projected.
