Title: Tectonic Framework of Eola and Southeast Hoover Oil Fields and West Timbered Hills Area, Garvin and Murray Counties, Oklahoma

Author(s): Bruce H. Harlton (2)

Abstract:

The Eola structure lies in subsurface just northwest of the western part of the Arbuckle Mountains and consists of three distinct, west-northwest-trending fault blocks. The surficially overturned faults are related to recurrent and predominantly vertical movements along basement structures. All of the faults are practically vertical at depth.

The distinctive character of the tectonics reveals that the fault blocks were created as a by-product of renewed regional tension on older faults. Differential distribution of force occurred along the bottoms of the segmented basement blocks and its deeper substratum, and subsequent recurrent movements produced the faults and block structures. The distinct linearity of the faults in this region shows a remarkably uniform stress distribution. The occurrence of Simpson (Ordovician) rocks over Goddard and Woodford (Mississippian) strata encountered in numerous wells is considered the result of tectonic landslides. The main production at Eola is from sandstones of Simpson (Ordovician) age.

The Southeast Hoover field lies adjacent to the north side of the exposed Arbuckle Mountains. Production is from upper Arbuckle limestone of Early Ordovician age.
