Proprietary Technology Utilized At Lake Mead

Acoustic Televiewer (ABI) logging was performed in three horizontal boreholes in the underground shaft at Lake Mead National Park, Boulder City, NV. Because the boreholes were ejecting water between 150 to 450 GPM, the ABI was deployed utilizing a proprietary “carrying devise” manufactured by Colog’s in-house fabrication shop. The drill rig pushed the carrier and centralized probe through a high pressure pack-off, at a slow constant speed, collecting fracture images throughout the entire length of the horizontal holes.
