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.
