Abstract
Herein is described a method of completing an interval of a cased well drilled through incompetent formation. This method includes a combination of three successive operations: zero-degree phasing perforation of a relatively small portion of the interval to be completed, consolidation of the formation zone around the perforations and injection of a propped fracturing fluid above fracture pressure to create a gap between the cement and the borehole and pack this gap with a proppant held by a proppant flowback-retention agent.
