Arbuckle Group, Oklahoma

Comments on Geologic Parameters

5 Percent Shale:

"The paucity of shales in the Arbuckle Group prevented the generation of stratabound seals that were barriers to vertical fluid movement. The widespread distribution of dolomitized grain-rich facies in combination with karstic dissolution contributed to the evolution of regionally extensive reservoirs in the Arbuckle" (Puckette, 1996, p. 73). We did not find any quantitative data concerning percent shale in the Arbuckle.
