US 2021/0277736 A1 · SETTING MECHANICAL BARRIERS IN A SINGLE RUN

Abstract

An operation may require isolation of a wellbore using multiple barriers. A single-run multiple barrier system may be deployed in a wellbore to position a first barrier at a first depth and a second barrier at second depth above the first barrier in the wellbore during a single run of a wellbore tubular string. The first barrier is coupled to a first miming tool. A wellbore tubular string segment couples the first miming tool is coupled to the second barrier. The second barrier is coupled to a second running tool that couples to the wellbore tubular string. The second barrier is locked until the first barrier is independently set at the first depth to prevent the second barrier from being set until the second depth is reached. Setting both barriers in a single run increases efficiency in an operation including reducing costs and time for completion of the operation.

Dependent claims

A method of setting a single-run multiple barrier system comprising:

deploying a single-run multiple barrier system on a wellbore tubular string in a wellbore of a formation, wherein the single-run multiple barrier system comprises a deep set barrier system at a distal end of the wellbore tubular string and a shallow set barrier above the deep set barrier system;
determining if a first depth in the wellbore has been reached by the single-run multiple barrier system;
setting a first isolation device of the deep set barrier system, wherein the shallow set barrier system comprises a rupture disk that prevents a lug from moving within a continuous j-slot to prevent setting of the shallow set barrier system during setting of the first isolation device;
disconnecting the deep set barrier system from the wellbore tubular string;
retrieving the wellbore tubular string to a second depth;
setting a second isolation device of the shallow set barrier system;
and
disconnecting the shallow set barrier system from the wellbore tubular string.
