Abstract
A bottomhole assembly (BHA) having a shifting tool and housing for shifting an uphole-to-open sleeve of a sleeve of a shorter length downhole sleeve assembly to an open position, and optionally to a closed position. Sleeve-engaging elements of the BHA are coordinated to direct the sleeve-engaging elements into a tool-engaging profile of the sleeve, excluding other annular variations in the casing string. The BHA has an improved dual J-Mechanism situated between the shifting tool and housing to permit new additional shifting options which results in fewer overall shifting cycles of the BHA when used with the shift uphole-to-open, shorter-length sleeve assembly. The shortened sleeve assembly is incorporated into a casing string and is relatively short in length when compared with conventional sleeve assemblies.
