Abstract
Abstract: North Tisdale Oil Mine, Johnson
Co., Wyoming
By
The North Tisdale anticline was drilled by Conoco Inc. first
in 1952. Unfortunately, the structure had been breached by erosion and the solution gas had escaped long
before. Many million barrels of oil had been left behind without sufficient
energy to enter a borehole. The increasing value of oil made the recovery of this
oil viable, and a unique method of liquid oil recovery was begun.
An adit was driven into the reservoir and the liquids drained into a gallery for recovery.
Color slides provide the opportunity to view the inside of this producing oil
reservoir. Also, revealing information about perforating and cementing
techniques can be gained by studying the results in this mine. The practicality
of mining liquid oil, despite the problems associated with such an operation,
adds another dimension to recovery of more of the oil left in the ground by
conventional recovery methods. End_of_Record - Last_Page 3---------------
