Abstract: A method of completing a subterranean well and associated apparatus therefor provide efficient operation and convenience in completions where production of fluids from a lateral wellbore and a parent wellbore is desired. In one disclosed embodiment, the invention provides a method of completing a subterranean well wherein a tubular member having an aperture formed through a sidewall portion thereof is inserted through a junction of multiple wellbore portions. The aperture is positioned so that it faces one of the wellbore portions. Apparatus provided by the present invention include various forms of flow diverters which may be utilized in the method.

Abstract: In a subterranean well a one-trip production zone perforation and proppant fracturing operation is carried out using a workstring-supported perforation gun lowered into a casing nipple located in the production zone. Firing of the gun creates spaced apart aligned sets of perforations extending outwardly through a side wall portion of the workstring, the nipple, the surrounding cement, and into the production zone, after which the gun falls into and is retained in an underlying gun catcher portion of the workstring. While an axial tension or compression force is imposed on the workstring above the aligned perforations to maintain their alignment, a proppant slurry is pumped down the workstring, out its sidewall perforations, and outwardly through the aligned perforation sets formed in the nipple, cement and production zone.

Abstract: A method of completing a subterranean well and associated apparatus therefor provide efficient operation and convenience in completions where production of fluids from a lateral wellbore and a parent wellbore is desired. In one disclosed embodiment, the invention provides a method of completing a subterranean well wherein a device having multiple portals is positioned at a junction of multiple wellbore portions and engaged with other structures positioned in the well. Several alternate constructions of a device for use with the method are provided as well.

Abstract: A method of completing a subterranean well and associated apparatus therefor provide reduced trips into the well, efficient operation, reduced costs, and increased functionality in completions where production of fluids from a lateral wellbore and a parent wellbore is desired. In one disclosed embodiment, the invention permits simultaneous conveying into the well of multiple tubing strings, the tubing strings being automatically directed to their respective wellbores. A selective deflection member is capable of selecting an appropriate tubing string and deflecting it into a lateral wellbore, while permitting another tubing string to pass axially therethrough to a lower parent wellbore.
