A coplanar jetting head for well perforating. The apparatus comprises a housing defining a plurality of jetting openings therein. The jetting openings are substantially coplanar and are angularly disposed with respect to a longitudinal axis of the housing. Each of the jetting openings has a jetting nozzle disposed therein. In the preferred embodiment, the angle of the plane of the jetting openings is such that the plane may be positioned substantially perpendicular to an axis of least principal stress in a well formation adjacent to the well bore when the housing is disposed in the well bore. A method of fracturing a well is also disclosed and comprises the steps of positioning a jetting head in a well bore and directing a plurality of fluid jets from the jetting head at an angle with respect to the longitudinal axis of the well bore.
A jetting apparatus for use in perforating a well bore, said apparatus comprising a housing defining a plurality of jetting openings therein, said jetting openings being substantially in a single plane which is disposed at an angle other than perpendicular with respect to a longitudinal axis of said housing, such that fluid is jetted in said plane from said jetting openings.
A method of fracturing a well formation comprising the steps of:
