The story of the Mississippian lime play began over a century ago and captures the evolution of oil and gas exploration in Kansas and Oklahoma--from early drilling of simple traps to the current development of unconventional resource plays characterized by high fluid volume and the associated intensive surface and subsurface plumbing infrastructure. Exploration and development of these complex and stacked reservoirs relies in large part on the geological understanding of the reservoir for accurate placement of horizontal wells as well as the implementation of efficient production practices.
