Demystifying Tight–Gas Reservoirs Using Multi–Scale Seismic Data

B010 Demystifying Tight–Gas Reservoirs Using Multi– Scale Seismic Data M.W. Roth* (Transform Software & Services Inc.) J. Shemeta (Pinnacle Technologies) & T. Davis (Colorado School of Mines) SUMMARY Low permeability fluvial reservoirs in the US Rocky Mountain region are estimated to hold nearly 7000 tcf of gas reserves (DOE 2003). In a typical reservoir several hundred feet of stacked sands are gas charged with natural and induced fractures being essential for economic gas production. While “traditional” seismic data is useful for identifying major geologic interfaces and faults the thin and complex nature of these channel sands are typically below seismic
