Abstract:
1. A system for depth referencing and installing tubular strings in a wellbore, the system comprising: a depth reference coupling positioned in a first tubular string installed in the wellbore, the first tubular string having a predetermined length between the depth reference coupling and a predetermined reference point, the depth reference coupling having a profile; an indicator assembly positioned in a second tubular string, the indicator assembly having a mating profile operable to engage the profile of the depth reference coupling; a service string releasably engageable with the second tubular string and operable to run the second tubular string in the first tubular string until the mating profile of the indicator assembly engages the profile of the depth reference coupling; and a suspension tool positioned in the second tubular string uphole of the indicator assembly, the suspension tool selectively operable to support the second tubular string within the first tubular string.
