Abstract: A downhole tool subassembly having an outer sleeve with a first set of apertures extending from an inner bore through an external surface of the outer sleeve. The downhole tool subassembly further includes a pin coupled to the outer sleeve and extending inward from the inner bore of the outer sleeve, and an inner sleeve slidingly engaged with the with outer sleeve. The inner sleeve has a slot and a second set of apertures extending from a sleeve bore of the inner sleeve through an external surface of the inner sleeve, and is operable to restrict flow across the first set of apertures when the inner sleeve is in a first position. The pin engages the slot, which includes a first tracking path and a second tracking path. The slot also includes a first transition path extending from the first tracking path to the second tracking path.

Abstract: A diverter assembly includes a tubing segment and one or more sleeve members disposed therein. The tubing segment includes apertures that are selectively alignable with apertures of an inner sleeve disposed within the tubing segment. The tubing segment includes a series of stops (e.g., shear pins) to arrest movement of the first sleeve within the bore of the tubing segment. A first one or more ball seats are included in the first sleeve such that deployment of a first ball and pressurization of the well above the first ball causes a first set of shear pins to fail, thereby allowing the first sleeve to slide downhole to cause apertures of the sleeve to align with apertures of the tubing segment, thereby causing fluid to flow to an annulus between the tubing segment and wellbore wall.

Abstract: A downhole tool subassembly has an outer sleeve with a first set of apertures extending from an inner bore of the outer sleeve. An intermediate sleeve positioned is within the outer sleeve and defines an intermediate flow path extending from an inner bore of the intermediate sleeve to a cavity formed between the uphole portion of the outer sleeve and the downhole portion of the intermediate sleeve. An inner sleeve is positioned within the intermediate sleeve and has an external sealing portion that restricts flow across the intermediate flow path when the downhole tool is in a first configuration.
