Title: Sand Hills Area, Crane County, Texas

Author(s): Elliot H. Powers (2)


The Sand Hills area of west-central Crane County includes the Tubb and McKnight pools, in which production is obtained from Permian dolomite. In a third small area on the northwest side of the Tubb pool, five wells have encountered flush production of high-gravity oil near the top of the Lower Ordovician dolomite, and two small wells are producing from a sandstone member of the Middle Ordovician.

Lower Permian dolomite lies unconformably on the eroded surface of a seemingly complex structural system, which involves Lower and Middle Ordovician sediments. Intermediate beds of probably Upper Ordovician, Silurian, and Devonian ages, respectively, appear in a test which was drilled approximately 8 miles southeast of the Ordovician producing area.
