The report summarizes the results of five radioactive tracer surveys, one comparison of pre- and post-stimulation fracture identification logs, and presents stress/mechanical properties information from three wells in the Antrim Shale of the Michigan Basin. The purpose of this work, based on wells located in Section 29, 31 and 32 of T3ON, R1W, and in Section 17 of T29N, R1W, was to provide insights into fracture growth behavior in the Antrim Shale. While highly interpretive and conflicting at times, the data seem to suggest (1) that both the Lachine and Norwood shales are fractured during single-stage treatements, (2) that the Paxton appears to be a good fracture barrier, (3) fracture height growth into the Ellsworth is possible when the Lachine is stimulated, and (4) discreet vertical intervals of fracturing occur in the Lachine as opposed to a single, continuous vertical fracture over the entire interval.
