Seismic Stratigraphic Analysis of Intracratonic Basin Sandstone Reservoir

William E. Galloway, Shirley P. Dutton

Abstract

Exploration and development of sandstone reservoirs in terrigenous depositional systems of Mid-Continent basins require detailed mapping of complex, laterally discontinuous, and commonly thin units. Reservoir sandstones of proximal upland, stable shallow platform, and deep-water cratonic basin settings are typically moderately to highly consolidated, forming intermediate velocity units vertically bounded by lower velocity mudstone and higher velocity limestone. Velocity variation greatly exceeds variations in density, and may be used to adequately approximate impedance contrast for seismic modeling studies. Field studies demonstrate the capabilities and limitations of seismic modeling in more accurately delineating sand-body geometry and distribution in cratonic basin sequences.
