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 rig. Televiewer and flow-logging were performed to evaluate the vertical distribution of permeability in the coreholes and […]
