Seismic Expression of the Damme Field, Finney County, Kansas

Abstract

Damme field, located in Finney County, Kansas, produces oil from Mississippian and Pennsylvanian carbonates and sandstones. Trapping is due to both structure and stratigraphy. First discovered in 1951, this field has produced 15 million barrels of oil and is still producing today.

The structural nature of Damme field is readily observed on CDP-seismic data acquired over the field. The erosional topography on the Mississippian (pre-Pennsylvanian) unconformity reveals a fault-bounded structure, and thick Morrow deposits fill in the surrounding paleotopographic lows. The influence of basement block faulting is suggested by the seismic data as well as by aeromagnetic data in the area. The structural relief is rapidly attenuated in the overlying Pennsylvanian section, and the buried paleotopography is described very well by mapping of the Permian to Mississippian interval.

This paper describes the seismic expression of Damme field with modern CDP seismic, and contrasts this expression with the predicted model response generated from well-log information in the field. The basement influence is also examined as described by published aeromagnetics and Precambrian structure maps.
