Embodiments of the present invention enables users to determine the efficiency of acid fracturing in stimulating a formation. The testing procedures of embodiments of the present invention examine the elastic, plastic, and creeping effects on closing an acidized fracture during the life span of an oil/gas well. If it is determined that an acidized fracture will be closed for a given stress and temperature, then proppant fracturing should be used; otherwise, acid fracturing is the stimulation treatment to consider. The testing results also provide an estimation of the lifetime of an acid fracture for a given set of in-situ conditions of stress and temperature. If the lifetime is determined to be too short to make the fracturing treatment economically feasible, a different stimulation method should be considered, such as proppant fracturing or matrix acidizing.
