Abstract
An apparatus, system and/or method for making observations down a wellbore are provided. The wellbore observation system may comprise a mandrel that can be run downhole, and telescoping tracks can be utilized to move a camera and semi-conforming inflatable bladder out of the mandrel and into the wellbore. Once the bladder is inflated, it displaces high turbidity fluid in the wellbore to allow the camera to move about a track and observe the wellbore unobstructed. An alternative embodiment allows the mandrel and telescoping tracks to be utilized with other tools to perform cleaning, fishing, diagnostic, and analytic operations.

An assembly for making observations down a wellbore, comprising:
- a tubular body having an interior cavity, the tubular body having a longitudinal axis and an outer diameter;
- a first track connected to the tubular body and positioned in the interior cavity, wherein the first track is oriented substantially parallel to the longitudinal axis;
- a second track movable relative to the first track;
- a camera movable relative to the second track;
- a bladder having an interior volume and an outer diameter, wherein the camera and at least a portion of the second track are positioned in the interior volume;
- wherein in a first position, the camera, the second track and the bladder are positioned inside of the interior cavity;
- and
- wherein in a second position, the camera, at least a portion of the second track, and at least a portion of the bladder are positioned outside of the interior cavity, and the outer diameter of the bladder is larger than the outer diameter of the tubular body.
A method of making observations down a wellbore, comprising:
- providing a tubular body having:
- an interior cavity, the tubular body having a longitudinal axis and an outer diameter;
- a first track connected to the tubular body and positioned in the interior cavity, wherein the first track is oriented substantially parallel to the longitudinal axis;
- a second track movable relative to the first track;
- a camera movable relative to the second track;
- a bladder having an interior volume and an outer diameter, wherein the camera and at least a portion of the second track are positioned in the interior volume;
- and
- wherein in a first position, the camera, the second track and the bladder are positioned inside of the interior cavity;
- moving the camera into a second position by:
- moving the second track, the bladder, and the camera on the first track relative to the tubular body until at least a portion of the second track and at least a portion of the bladder are positioned outside of the interior cavity;
- inflating the bladder such that the outer diameter of the bladder is larger than the outer diameter of the tubular body;
- and
- moving the camera to a desired location on the second track.
An assembly for providing tool access in a wellbore, comprising:
- a tubular body having an interior cavity, the tubular body having a longitudinal axis and an outer diameter;
- a first track connected to the tubular body and positioned in the interior cavity, wherein the first track is oriented substantially parallel to the longitudinal axis;
- a second track movable relative to the first track;
- a tool coupled to the second track;
- wherein in a first position, the tool and the second track are positioned inside of the interior cavity, and the tool is entirely positioned in the interior cavity;
- and
- wherein in a second position, the tool and at least a portion of the second track are positioned outside of the interior cavity.
