Summary: | This invention relates to a method of completing a well in a poorly consolidated formation-bearing hydrocarbon to minimize flow of particulates such as sand into a wellbore. The invention proposes a screen-less completion method that can be carried out with coiled tubing equipments.
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. |
