US 8,770,285 B2 · Systems and methods for locating wellbore servicing tools within a wellbore

Abstract

Disclosed are methods and systems for accurately locating wellbore servicing tools within a wellbore. A positioning system includes an elongate housing defining a piston bore with first and second axial ends, a sleeve arranged within the piston bore and having an upset extending radially outward therefrom, one or more lugs arranged within the elongate housing and radially movable when acted upon by the upset, a first biasing device arranged within the piston bore at the second axial end, and at least one RFID tag arranged on the production tubular and configured to communicate with at least one RFID reader arranged on the elongate housing, the at least one RFID reader being configured to deploy the first biasing device upon communicating with the at least one RFID tag, and thereby force the sleeve toward the first axial end and the upset into engagement with the lugs which engage a profile.

Dependent claims

A positioning system for locating a wellbore servicing tool within a production tubular, comprising:

an elongate housing defining a piston bore having a first axial end and a second axial end;
a sleeve arranged within the piston bore and being axially translatable between the first and second axial ends, the sleeve having at least one upset extending radially outward therefrom;
one or more lugs arranged within the elongate housing and being radially movable when acted upon by the at least one upset;
at least one spring arranged between the one or more lugs and an inner radial surface of the piston bore, the at least one spring being configured to radially bias the one or more lugs against the sleeve;
a first biasing device arranged within the piston bore at the second axial end and movable between a stowed configuration and a deployed configuration;
and
at least one RFID tag arranged on the production tubular and configured to communicate with at least one RFID reader arranged on the elongate housing, the at least one RFID reader being configured to deploy the first biasing device upon communicating with the at least one RFID tag.

A method for locating a wellbore servicing tool within a production tubular, comprising:

introducing the wellbore servicing tool into the production tubular, the wellbore servicing tool being coupled to an elongate housing defining a piston bore having a first axial end and a second axial end;
communicating at least one RFID reader arranged on the elongate housing with at least one RFID tag arranged on the production tubular, and thereby deploying a first biasing device from a stowed configuration to a deployed configuration, the first biasing device being arranged within the piston bore at the second axial end;
moving a sleeve with the first biasing device toward the first axial end, the sleeve being arranged within the piston bore and having at least one upset extending radially outward therefrom;
engaging the at least one upset on one or more lugs arranged within the elongate housing, and thereby radially extending the one or more lugs at least partially without the elongate housing, wherein the one or more lugs are radially biased against the sleeve with at least one spring arranged between the one or more lugs and an inner radial surface of the piston bore;
and
engaging the one or more lugs on a profile arranged on an inner radial surface of the production tubular, thereby stopping an axial progression of the wellbore servicing tool.
