Abstract

A system may include a handling mast, a tubular source stack, a tubing loader, a spider device, and a connection device. The tubing loader is configured to capture a first HVT from the tubular source stack, load the first HVT into the handling mast, capture a second HVT from the tubular source stack, and load the second HVT into the handling mast. The spider device is configured to grasp the first HVT. The connection device is configured to align a proximal end of the first HVT and a distal end of the second HVT and couple the first HVT and the second HVT to form a tubing string. The handling mast is configured to insert the tubing string into the wellbore.

Claims16

Dependent claims

A system for installing high-value tubulars (HVT) in a wellbore, the system comprising:

a specialized tubing insertion rig (STIR) configured to handle a plurality of HVT so as not to damage each of the plurality of HVT and insert the plurality of HVT in the wellbore, wherein the STIR comprises:
a handling mast,
a tubular source stack, configured to store the plurality of HVT, and
a tubing loader configured to:
capture a first HVT from the tubular source stack;
load the first HVT into the handling mast;
capture a second HVT from the tubular source stack;
and
load the second HVT into the handling mast,
wherein the handling mast is configured to insert a downhole heat exchanger and the first HVT into the wellbore;
a spider device configured to grasp the first HVT so that the first HVT is suspended at least partially within the wellbore by the spider device;
and
a connection device configured to:
align a proximal end of the first HVT and a distal end of the second HVT;
and
couple a first portion of a fastening component of the proximal end of the first HVT and a second portion of the fastening component of the distal end of the second HVT to form a tubing string, wherein the STIR is configured to insert the tubing string into the wellbore;
and
a control system configured to:
determine a number of rotations of the proximal end of the second HVT during coupling of each HVT;
determine if a torque experienced between the proximal end of the first HVT and the distal end of the second HVT is greater than a preset torque threshold.

A method for installing high-value tubulars (HVT) in a wellbore penetrating a source formation, the method comprising:

placing a specialized tubing insertion rig (STIR) at a well site including the wellbore,
wherein the STIR is configured to handle a plurality of HVT so as not to damage each of the plurality of HVT and insert the plurality of HVT in the wellbore, wherein the plurality of HVT comprises a first HVT and a second HVT;
capturing, using a tubing loader, the first HVT from a tubular source stack,
wherein each of the plurality of HVT comprises a distal end and a proximal end,
wherein each distal end comprises a first portion of a fastening component and each proximal end comprises a second portion of the fastening component;
loading, using the tubing loader, the first HVT into a handling mast;
disposing a downhole heat exchanger on the distal end of the first HVT;
inserting, using the handling mast, the downhole heat exchanger and the first HVT into the wellbore,
wherein the first HVT is inserted with the distal end inserted first and is inserted until the proximal end is positioned adjacent to a spider device configured to grasp each HVT;
grasping, using the spider device, the first HVT so that the first HVT is supported at least partially within the wellbore by the spider device;
capturing, using the tubing loader, the second HVT from the tubular source stack,
loading, using the tubing loader, the second HVT into the handling mast;
aligning, using a connection device, the proximal end of the first HVT and the distal end of the second HVT;
coupling, using the connection device, the first portion of the fastening component of the proximal end of the first HVT and the second portion of the fastening component of the distal end of the second HVT to form a tubing string;
determining a number of rotations of the proximal end of the second HVT during coupling of each HVT;
determining if a torque experienced between the proximal end of the first HVT and the distal end of the second HVT is greater than a preset torque threshold;
and
inserting, using the handling mast, the tubing string into the wellbore if the torque is not greater than the preset torque threshold.
