The economic viability of field-development projects in low-permeability or “tight” gas sands depends on identifying optimum field well spacing in order to maximize gas recovery with the fewest number of wells.
The type and effectiveness of the stimulation treatment is key to optimizing well spacing.

Most wells completed in tight gas sands require some type of hydraulic fracturing to achieve economic production. Wells with longer, more conductive...
