181 PROCEDURES AND EQUIPMENT FOR PROFILING AND JOINTING OF PIPES EP99962300.2 1999-12-21 EP1147287A2 2001-10-24 SIMPSON, Neil, Andrew, Abercrombie
Methods and apparatus for shaping pipes, tubes, liners, or casing at downhole locations in wells. Use is made of rollers bearing radially outwards against the inside wall of the pipe (etc.), the rollers being rolled around the pipe to cause outward plastic deformation which expands and shapes the pipe to a desired profile. Where one pipe is inside another, the two pipes can be joined without separate components (except optional seals). Landing nipples and liner hangers can be formed in situ. Valves can be deployed to a selected downhole location and there sealed to the casing or liner without separate packers. Casing can be deployed downhole in reduced-diameter lengths and then expanded to case a well without requiring larger diameter bores and casing further uphole. The invention enables simplified downhole working, and enables a well to be drilled and produced with the minimum downhole bore throughout its depth, obviating the need for large bores. When expanding lengths of casing, the casing does not need to be anchored or made pressure-tight. The profiling/expansion tools of the invention can be deployed downhole on coiled tubing, and operated without high tensile loads on the coiled tubing.

A method of completing a well includes injecting a consolidatable resin coated particulate slurry through production casing set in the production zone of a producing formation such that said slurry flows into an annulus formed between the casing and the wellbore to form a zone of high conductivity communicating with said casing and said formation and concurrently with such injection creating at least one fracture in said formation with said slurry; permitting said consolidatable resin to harden; and perforating the casing and consolidated zone. Prior to injection of the particulate slurry, a first fluid may be introduced through the casing into the annulus at such a rate that the first fluid removes undesired debris and mudcake from the wall of the wellbore.
