This Standard Practice provides recommendations for exploratory activities seeking new sources of natural material, normally referred to as proppant, used in hydraulic fracture stimulation operations. Proppant is a major component in the slurry used in fracture stimulation of subterranean formations. Its purpose is to prop open the hydraulically-induced fractures, preventing them from closing and thus maintaining a high fluid conductivity around the well bore. The increased contact area significantly improves the transfer rate of fluids or heat into or out of the target formation. This Standard Practice addresses the several components of a proppant exploration program, starting with selection of potential target formations, field sampling methods, laboratory evaluation of the material and reporting of the results.
Recent advances in directional drilling and hydraulic fracture stimulation have significantly increased demand for proppant. The trend seems to be continuing as
