Waulsortian mound development in Warsaw at Broughton field, Ill.
- IBEX Geological Consultants Inc., Champaign, IL (United States)
Oil production in the Lower Mississippian Ullin (Warsaw) limestone was first established in Illinois over 40 years ago. Exploration for hydrocarbons in this zone, however, was limited until recently due to a lack of a suitable explanation for reservoir development in this interval. The theory that Waulsortian mound development may explain many of these reservoirs was first presented in 1990. Research effort led by Zakaria Lasemi at the Illinois State Geological Survey has since established an excellent model for the generation of these bioherms. Lasemi performed numerous examinations of outcrops, cores, and well cuttings to develop his theory on the development and evolution of these biohermal features. This article presents an application of Lasemi`s model to an oil field in the Illinois basin. Similar applications could improve exploration and development success in Warsaw reservoirs.
