Beschreibung
Zusammenfassung:	A diverter assembly (200) includes a tubing segment (202) and one or more sleeve members (204, 206, 208) disposed therein. The tubing segment includes apertures (228) that are selectively alignable with apertures of an inner sleeve (208) disposed within the tubing segment. The tubing segment includes a series of stops (e.g., shear pins) to arrest movement of the first sleeve (206) within the bore of the tubing segment. A first one or more ball seats (240, 242) are included in the first sleeve such that deployment of a first ball (262) and pressurization of the well above the first ball causes a first set of shear pins (210) 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.
