This paper summarizes stimulation results from an openhole horizontal well that was treated with a new fracturing process called hydrajet fracturing. With this process, operators can accurately place many fractures at different locations in a horizontal well without using sectional isolation techniques. In particular, the process uses high-pressure jetting to concentrate fracturing energy at a precise fracture location. Surface and downhole pressure recorders, flow recorders, and tracers obtained pertinent data for further study of the process. The well in this study was hydrajet-fractured with acid.

This study demonstrates that openhole horizontal wells can be hydrajet-fractured effectively and economically.
