Video Logging

Drillers use the vertical and horizontal views captured by our downhole video camera to examine borehole integrity before placing water well casing, well screens, and submersible pumps. Hydrologists and geologists use the images to verify geophysical data such as: changes in rock type, small-scale geologic structures, rock fractures, and groundwater movement.

Sedimentation of Lower Granite Reservoir, operated by the U.S. Army Corps of Engineers, affects commercial navigation and reservoir storage capacity. Some groups are concerned that dredging the reservoir to remove excess sediment may negatively affect endangered species such as steelhead and salmon.
