Abstract

The productive ooid shoals of the St. Louis Formation (Mississippian, Meramecian) in southwestern Kansas have been interpreted as representing linear ramp barrier-type deposits that developed southwest of, and parallel to, a southeasterly trending shoreline. However, examination of available cores and interpretation of petrophysical log data from the Ingalls field in Gray County suggest that production is from an oolite shoal situated on the leeward side of a small "island" mudflat. Positive magnetic and gravity anomalies associated with the Ingalls field imply deep structures that might have resulted in subtle perturbations on the Mississippian sea floor that in turn provided loci for ooid shoal formation. Classified lithologically as an oolitic grainstone, this principal productive facies exhibits primary inter- granular porosity with evidence of only minor diagenetic porosity enhancement. A possible implication for future exploration is that St. Louis Formation oolitic buildups may be present in pairs, occurring on both the leeward and basinward sides of coastal plain "islands" that might have formed an archipelago extending into the Hugoton embayment of the Anadarko basin.
