F.A.S.T. RTA™ Advanced Production Decline Analysis F.A.S.T. RTA™ is a cutting edge decline analysis tool that analyzes production rates and flowing pressures. Methods include traditional decline analysis, Fetkovich, Blasingame, Agarwal-Gardner, NPI, Transient and Wattenbarger type curves, specialized analysis and flowing material balance. Reservoir models include volumetric and water-drive. Well models include horizontal, vertical, and hydraulically fractured wells. F.A.S.T. RTA™ analyzes production data, yielding EUR, hydrocarbons-in-place, drainage area, aquifer strength, permeability, skin, and fracture half-length. It allows users to evaluate infill potential, characterize the reservoir, and estimate reserves with ease and efficiency. Files created with F.A.S.T. WellTest™ (version 7.0+) can be opened directly in F.A.S.T. RTA™ (version 3.5+) to quickly apply production analysis techniques.
