Methods for discharging fluent substances into well bores
A method is described for reliably discharging a homogeneous mass of selected fluent substances around a well perforator and then perforating an interval of a well bore traversing this mass of fluent substances so that the selected substances will enter the resulting perforations rather than being diluted by or being dispersed through other fluids in the well bore. This is accomplished by positioning a tool, including a perforator, adjacent to a formation interval to be completed. As the perforator is moved into alignment with the formation, fluids in the well bore are removed from the space to be occupied by the perforator and simultaneously replaced with a fluent treating substance. Thus, upon actuation of the perforator, the treating substance will enter the resulting perforations without interference from the displaced well-bore fluids. (4 claims)
