Patent attributes
A wellbore completion is disclosed. The wellbore completion comprises a casing assembly comprising a plurality of casing lengths. At least one collar is positioned so as to couple the casing lengths. The at least one collar comprises a tubular body having an inner flow path and at least one fracture port configured to provide fluid communication between an outer surface of the collar and the inner flow path. A length of coiled tubing can be positioned in the casing assembly. The coiled tubing comprises an inner flow path, wherein an annulus is formed between the coiled tubing and the casing assembly. A bottom hole assembly is coupled to the coiled tubing. The bottom hole assembly comprises a fracturing aperture configured to provide fluid communication between the inner flow path of the coiled tubing and the annulus. A packer can be positioned to allow contact with the at least one collar when the packer is expanded. The packer is capable of isolating the annulus above the packer from the annulus below the packer so that fluid flowing down the coiled tubing can cause a pressure differential across the packer to thereby open the fracture port.
