Abstract: South Eubank Field: Successful Development of Deeper Reserves Using 3D Seismic

A portion of recent field development efforts in the Hugoton Embayment of western Kansas have focused on deeper Mississippian-age sandstone reservoirs of the Chester series. Such efforts yielded particular successes in the case of the South Eubank field, Haskell County Kansas. Subsurface mapping and 3-D seismic information led to over 30 new producers being drilled in this field. Reservoirs are best developed in fine-grained, well-sorted Chester sandstones filling a narrow incised paleo-valley system that runs north-south through the field. 3-D seismic data was required to accurately delineate the paleo-valley system and locate specific drill sites. Success at South Eubank suggests that other portions of the same valley system might be similarly developed.
