Selecting a correct frac sand or proppant to be used in a conventional hydraulic fracturing treatment is vitally important. A thorough evaluation of the proppant is required to ensure the selected proppant is correct and proper for the treatment. Among various evaluation methods, crushing of proppant is an important method. The crushing of proppant and the amounts of generated fines determines the stress closure the proppant can sustain. Taking the advantage and availability of acoustic emission (AE) technology, a method of using AE signals generated during crushing of proppant to evaluate the quality of sand or proppant is presented. A combination of proppant crushing and analysis of AE helps classify the proppant quality. This test method can be simplified to be readily available and applied by personnel in field locations.
