This paper presents the results of field trials conducted primarily to evaluate the efficacy of a new additive developed specifically for use in fracturing coal seams and shale wells. The case histories were carefully chosen so that the effects related to use of the new material could be isolated as well as possible. The data show that substantial production improvements may be achieved. This paper also presents results from laboratory tests which show that the new additive may also be useful in workover treatments.
