Frequently Asked Questions
The downhole facing SC-166 is suitable for boreholes up to 10 inches in diameter. The R-CAM dual view camera can view boreholes up to 16 inches in diameter. The DC5150 is suitable for borehole diameters up to 30 inches in diameter. Please note, visibility downhole will be impacted by the clarity of the fluid and the available light.
Every camera system will eventually require a repair to the cable head, the point at which the cable and camera physically connect. Over time, the internal connections within the cable head can be strained to the point where they disconnect and cause interference or a complete loss of the video signal. To expedite the repair process, we have cable head repair kits available for both portable systems and large vehicle-based systems.
Conducting surveys with the included centralizers and available lens shield accessory is the best way to ensure that the camera head remains protected downhole. When not in use, store the camera head in an area where it will be safe from unintentional drops or damage. If your camera system is damaged, we offer full repair services at our headquarters in Fresno, California.
