In December 2016, T-Rex Oil, Inc. has announced that it has began its recompletion program in its Cole Creek Field, in the Powder River Basin, Wyoming. The recompletion program encompasses the identification of additional production from formations in existing well bores and then gaining such production through re-work methods. In late December 2016, the company performed re-work on the first of such well bores, moving from the Second Frontier Formation to the First Frontier Formation, expecting to increase production from the well bore. The company is awaiting final results of pumping efforts. The company intends to make similar formation moves with other existing well bores based upon the pending results from its first recompletion effort. Management believes that this a cost efficient method to increase production.
