Abstract
A cable introduction assembly that can include: a spool assembly including a spool having a first axis, the spool configured to retain a cable wound around the first axis in an undeployed mode; and a spool mount assembly configured to retain the spool and introduce the cable in a deployed mode into a conduit configured for a downhole environment, the conduit having a proximal end and a distal end, the cable in the deployed mode extending from the proximal end towards the distal end, wherein the spool assembly is configured to provide a handedness to the cable in the deployed mode.
Claims21
A cable introduction assembly comprising:
- a spool assembly including:
- a spool having a first axis, the spool configured to retain a cable wound around the first axis in an undeployed mode;
- and
- a spool mount assembly configured to retain the spool and introduce the cable in a deployed mode into a conduit configured for a downhole environment, the conduit having a proximal end and a distal end, the cable in the deployed mode extending from the proximal end towards the distal end, wherein the spool assembly is configured to provide a handedness to the cable in the deployed mode.
A downhole tool sensing system, the system comprising:
- a spool assembly including a spool having a first axis, the spool configured to retain a fiber optic cable wound around the first axis in an undeployed mode;
- a spool mount assembly configured to retain the spool and introduce the fiber optic cable in a deployed mode into a conduit configured for a downhole environment, the conduit having a proximal end and a distal end, the fiber optic cable being transported from the proximal end towards the distal end, the spool mount assembly configured to provide a handedness to the fiber optic cable in the deployed mode, and
- a motor configured to move the spool.
A method of deploying a fiber optic cable into a conduit comprising:
- deploying the fiber optic cable into a proximal end of the conduit;
- pumping a fluid into the conduit;
- propelling the fiber optic cable with the pumped fluid towards a distal end of the conduit;
- and
- twisting the fiber optic cable as it is deployed into the conduit so that the fiber optic cable retains one of a left handedness or a right handedness along its length in a deployed state.
A downhole tool sensing system, the system comprising:
- a coiled tubing configured for a downhole environment, the coiled tubing having a proximal end and a distal end;
- and
- a fiber optic sensing cable located within the coiled tubing, the fiber optic cable being coiled throughout its length in a single handedness direction, wherein the fiber optic sensing cable is configured to perform at least one of Distributed Temperature Sensing (DTS) and Distributed Acoustic Sensing (DAS).
