3D seismic attributes analysis to outline channel facies and reveal heterogeneous reservoir stratigraphy: Weirman Field, Ness County, Kansas, USA

In this paper, we present a workflow integrating several post-stack seismic attributes to assist in understanding development history of our study area. We also aim to shape future drilling plans by outlining a channel fill zone of better reservoir quality, and to highlight reservoir boundaries of compartmentalization. Extracting and analyzing acoustic impedance and amplitude attenuation, guided by a time window focused on the bottom of the Mississippian formation, resulted in an understanding of the key seismic channel-facies framework and helped to explain some of the disappointing drilling results at Weirman Field. This study recommends integrating the revealed compartmentalization boundary and the seismic channel-facies framework in future drilling plans of Weirman Field.
