Conglomerate and Breccia (Non-reservoir): Many conglomerates or breccias consist of rip-up clasts derived from underlying lithologies. Textures range from clast- to matrix supported. Conglomerates and breccias are commonly associated with desiccation and mud cracks, dewatering structures and teepees. Local autoclastic breccia textures indicate intra-Arbuckle subaerial exposure events. Some collapse breccia may have resulted from the dissolution of evaporites. These conglomerates indicate intra-Arbuckle high energy erosional and subaerial exposure events in subtidal to peritidal settings. The conglomerate and breccia facies typically has variable porosities and permeabilities that are primarily a function of the lithologies that were brecciated.
