Abstract

Electrically-operated downhole tools are run into a wellbore on a coiled tubing string which includes tube-wire that is capable of carrying power and data along its length. During operation, a downhole tool is provided power from surface using the tube-wire. Downhole data is provided to the surface via tube-wire.

First claim

What is claimed is:

1 . A downhole tool system for performing a function within a wellbore tubular, the system comprising:
an electrically-actuatable downhole tool; a coiled tubing running string secured to the downhole tool to dispose the downhole tool into the wellbore tubular; and a tube-wire within the coiled tubing running string and operably interconnected with the downhole tool, the tube-wire being capable of carrying electrical power and data along its length to or from the downhole tool.

2 . The downhole tool system of claim 1 wherein the downhole tool further comprises a housing with one or more arms which selectively extend outwardly from the housing, the arms being operable to move a sliding sleeve device within the wellbore tubular between open and closed positions.

3 . The downhole tool system of claim 2 further comprising a camera operably associated with the downhole tool to obtain one or more visual images of the wellbore tubular and transmit said image data to surface via the tube-wire.

4 . The downhole tool system of claim 1 further comprising a fiber optic distributed sensor contained within the coiled tubing running string to detect an operational parameter within the wellbore tubular.

5 . The downhole tool system of claim 4 wherein the fiber optic distributed sensor comprises a temperature sensor.

6 . The downhole tool system of claim 1 wherein the electrically-actuated downhole tool comprises a fluid hammer tool for interrogating fracturing in the wellbore tubular via generation of one or more pressure pulses.

7 . The downhole tool system of claim 6 further comprising a pressure sensor that is operably associated with the fluid hammer tool to detect pressure pulses generated by the fluid hammer tool and reflected pressure pulses.

8 . A downhole tool system for performing a function within a wellbore tubular, the system comprising:
an electrically-actuatable downhole tool; a coiled tubing running string secured to the downhole tool to dispose the downhole tool into the wellbore tubular; a tube-wire within the coiled tubing running string and operably interconnected with the downhole tool, the tube-wire being capable of carrying electrical power and data along its length to or from the downhole tool; and a power source operably associated with the tube-wire to provide operating power to the electrically-actuated downhole tool via the tube-wire.

9 . The downhole tool system of claim 8 further comprising:
a sensor operably associated with the downhole tool to sense a downhole parameter within the wellbore tubular and transmit a signal representative of the sensed parameter via the coiled tubing running string.

10 . The downhole tool system of claim 8 wherein the electrically-actuated downhole tool comprises a housing with one or more arms which selectively extend outwardly from the housing, the arms being operable to move a sliding sleeve device within the wellbore tubular between open and closed positions.

11 . The downhole tool system of claim 8 wherein the electrically-operated downhole tool further comprises a fluid hammer tool for interrogating fracturing in the wellbore tubular via generation of one or more pressure pulses.

12 . The downhole tool system of claim 10 further comprising a camera operably associated with the downhole tool to obtain one or more visual images of the wellbore tubular and transmit said image data to surface via the tube-wire.

13 . The downhole tool system of claim 8 further comprising a fiber optic distributed sensor contained within the coiled tubing running string to detect an operational parameter within the wellbore tubular.

14 . The downhole tool system of claim 13 wherein the fiber optic distributed sensor comprises a temperature sensor.

15 . A method for operating an electrically-actuated downhole tool, the method comprising the steps of:
securing the electrically-actuated downhole tool to Telecoil® running string, the Telecoil® running string comprising a coiled tubing string defining a flowbore within and a tube-wire disposed along the flowbore; disposing the electrically-actuated downhole tool into a wellbore from surface on the Telecoil® running string; providing electrical power to the electrically-actuated downhole tool from surface via the tube-wire; and obtaining data at surface from a sensor that is operably associated with the electrically-actuated downhole tool via the tube-wire.

16 . The method of claim 15 further comprising the step of shifting a sliding sleeve tool within the flowbore between open and closed positions with the downhole tool.

17 . The method of claim 15 further comprising the step of generating one or more fluid pulses with the downhole tool to interrogate a fracture in the flowbore.
