Use of a composite fracturing plug (CFP) reduces time required to complete Mesaverde-Meeteetse wells in the Wind River basin from months to days and makes rigless completions possible. Fracturing treatments consisting of repeated stages of acid, slick-water pad, and slick water with low proppant concentrations provide equal or better zone stimulation than conventional borate-crosslinked gel systems. Well productivity has improved because the wells are no longer killed between fracture treatments.
