Downhole Camera
|
The Method Lowering the downhole video camera into a well or vertical pipe provides a way of visually inspecting the feature’s integrity, the presence of obstructions, or the level of the water table, for example. |
Equipment Used Well-Vu WV-C1000 downhole camera |
|
Equipment Set-up of the Well-Vu WV-C1000 involves a tripod to hold the camera cord vertically above the pipe. The camera is attached to a cable on a motorized wheel that operates on a 12-volt battery. The system incorporates a 1.5 inch diameter video camera to provide a permanent record of the well or pipe conditions. LED lights, with adjustable brightness, on the end of the camera provide clear viewing at any depth. The camera has an output, which feeds a real-time image to a laptop computer with depth readings displayed in the video at 0.10-foot increments. Field Procedures The pipe/well that is to be inspected must be open and accessible and it will be necessary that it be allowed to stand undisturbed for at least several days prior to the survey in order to reduce turbidity. The operator will lower the camera into the pipe/well while viewing the video image on a computer screen. Before and after the inspection of the pipe/well, the equipment is properly decontaminated. |

Data Processing and Presentation Notes regarding features of interest including the depths are recorded in a field notebook while the camera is descending into the well. The video can be further reviewed in the office to insure all features of interest were identified during the field viewing of the video. The video file may be put onto a CD as a deliverable.
