The objective of this contract is to test the technical feasibility for the in situ processing of the Antrim oil shale within the Mississippian--Devonian black shale sequence of the Michigan Basin to produce energy values. In the report quarter explosive fracturing experiments were conducted in the wells involved in the explosive underream series and in the hydrofracture series. In total, four successful shots were made. In Well No. 301, a 20 foot section of well bore was enlarged to almost three times its original volume by the detonation of 1500 pounds of explosive. Wells No. 101, 104, and 106 were also explosively fractured. Preparations for fracturing Wells No. 103 and 105 are complete. In lab tests for the chemical underream experiment, a 4 foot zone was found to have a uniform and high hydrochloric acid solubility. Notching, fracturing, and acid underreaming experiments will be concentrated in this area. Data from the extraction trials on the front site have been compiled and plotted. A topical report on this experiment is being prepared. Two new methods of igniting shale were tested. Shale characterization and resource inventory activities continued at four major Michigan universities.
