Oomoldic Reservoirs of Central Kansas, Controls on Porosity, Permeability, Capillary Pressure and Architecture

Kansas Geological Survey Open-file Report 2002-48

Whereas Lansing-Kansas City reservoirs produce from 50 counties statewide, a significant portion of the total production has come from the 10 counties coinciding with the CKU. Within these counties, the Lansing-Kansas City has produced over 613 MMBO, representing about 26% of the total production from this region. Reservoirs in the L-KC account for nearly 20% of cumulative oil production for the state and presently represent 16% of current production.

Lansing-Kansas City reservoirs produce by solution gas and partial water drive. In many fields because of low dissolved gas content, primary recovery by solution gas drive is often modest with recovery efficiencies of less than 25%. These fields often exhibit secondary recoveries that exceed primary, however, many fields do not respond to waterflooding leaving high residual oil saturations.
