Integrating PSDM Seismic into Geological and Petrophysical Modeling of the Mississippian at Wellington Field

Jason Rush

Abstract

The Kansas Geological Survey is undertaking an extensive, DOE-funded, reservoir characterization project for the Mississippian at Wellington Field (Sumner County, Kansas). A common goal for these multi-contract, DOE awards is to demonstrate – ultimately through a pilot program – the potential for CO2-EOR in the Mississippian reservoir and CO2 storage (sequestration) within the Arbuckle saline aquifer. Wellington Field was discovered in 1929 and has produced over 20 MMBO from the Mississippian chat, or Cowley facies. The field, operated by BEREXCO, is currently under waterflood. Wellington Field is situated along the Mississippian shelf margin and west of the Nemaha Uplift. New data for reservoir characterization and geocellular modeling includes multi-component 3-D seismic, extensive wireline logging programs that includes magnetic resonance and micro imaging tools, and through-going core. For this part of the program, we will describe the depositional setting, show PSDM seismic interpretations, discuss integration of 3-D seismic attributes, and demonstrate our workflow for generating 3-D geostatistical facies and petrophysical models of the Mississippian at Wellington Field.
