  • Patent number: 7240733
    Abstract: Openings are created between a wellbore and a formation by firing a perforating gun adjacent to a zone in the formation and the production fluids are produced along with any formation debris. A tubing string extending to the formation is pressurized to actuate the perforating gun and simultaneously to actuate a downhole injection port. Substantially immediately thereafter fluids are injected into the wellbore near the openings and circulated to the surface for the removal of debris and the production of the formation fluids. An optional and uphole injection port can be used to adjust the hydrostatic head above the perforating gun with the removal or addition of fluid prior to actuation. The tubing string extends sufficiently above the wellbore at surface to enable lowering of the downhole injection port below the openings during fluid circulation for enhanced removal of debris.

  • Patent number: 7213648
    Abstract: Openings are created between a wellbore and a formation by firing a perforating gun adjacent a perforating zone in the formation and debris is removed. A tubing string extending to the formation is pressurized to a first pressure to actuate the perforating gun. A second higher pressure is applied to activate a downhole injection port. Substantially immediately thereafter fluids are injected into the wellbore near the openings and circulated to the surface for the removal of debris. An optional and uphole injection port can be used to adjust the hydrostatic head above the perforating gun with the removal or addition of fluid. The tubing string extends sufficiently above the wellbore at surface to enable lowering of the downhole injection port below the openings during fluid circulation for enhanced removal of debris.
