GREAT™

GREAT™ software provides easy-to-use, full-featured reservoir engineering tools without the complexity or expense of other reservoir simulators.

Features:

• Gas reservoir simulator for single-phase flow in spatially variable properties on a fixed grid
• Efficient well recurrent data input
• View well rates and pressure output
• Easy to use framework
• Fully implicit formulation
• Fluid property calculation, flash calculation, decline curves, isochronal testing, gas pressure transient analysis, p/z analysis, volumetric calculation, and z-factor calculation
