Dewatering Study Near Leadville, CO
A project involving hydrophysical logging (HpL) under ambient and pumping conditions was used to evaluate the vertical distribution of hydraulic conductivity in a mine borehole. The corehole was in a strategic location on site: drilled into a fault intersecting two...
Sensitive Environmental Study for Remediation Planning
Multiple logging measurements were needed to design optimal remediation plans at an environmentally sensitive site. A study performed for two different clients at this southern CA location involved Optical Televiewer and Acoustic Televiewer, along with EM Induction...
Sonar Applications in Submerged Mine Workings
COLOG has adapted a multi-frequency profiling sonar probe that can be logged from any 4-conductor standard geophysical logging rig, for imaging submerged mine workings, large diameter shafts, raised bores, karst environments and large diameter boreholes. Much of the...
Rio Grande River Basin Horizontal Groundwater Characterization
COLOG was hired to characterize the horizontal movement of groundwater through the Rio Grande River Basin . This project proved challenging due to the complex hydrogeology and lack of historical geologic data from past drilling programs. In the Rio Grande Basin, many...
Municipal Water Supply Well for Tucson, AZ
One of the more common applications of geophysical logging for COLOG’s Arizona office is “The Water Well Suite”. Consulting companies hired by water municipalities to drill and construct water supply wells will typically drill a pilot borehole and request a...
Great Lakes Hydrophysics and Crosshole Packer Testing
A Great Lakes region project included Hydrophysical Logging (HpL), Wireline Straddle-Packer (WSP) testing, optical televiewer and Corehole Dynamic Flowmeter (CDFM) in angled and vertical coreholes up to 3,000 feet deep. Tools were all run from a standard geophysical...Need a CPR or First Aid Class?
Periodically, Colog’s Health and Safety Manager, Catie O’Neil, will host a class for CPR and First Aid certification. We are more than happy to share her knowledge with other individuals or companies. If you have people in need of training or a refresher, give us a...COLOG Opens Arizona Office
COLOG has opened an office in Arizona to better serve clients who have projects in and around the the southwest region. Arizona’s own STEVE STROUD has been hired to run this new location. Steve comes to COLOG with direct experience in borehole logging and data...CONTACT US BY
