Swope Oolites

Isopach map of Swope Limestone with porosity greater than 8% using the same well data as the upper map. Porous carbonate is mainly oolitic lithologies dominated by oomoldic pores. Whereas the large-scale lobes in the map resemble in form modern oolite shoals, these lobes are interpreted to represent composites of temporally distinct shoals similar in scale to shoals deposited in the present-day Joulter’s Cays region.
