ABSTRACT:
A system for determining a subsurface parameter from a drilled wellbore includes a casing, a logging tool comprising one or more logging devices, and a latching device coupling the logging tool to the casing such that the logging tool hangs below the casing when the casing is disposed in the wellbore. A method of determining a subsurface parameter includes disposing a casing in a wellbore, coupling the logging tool to the casing such that the logging tool hangs below the casing, and running the casing along the wellbore, wherein the logging tool makes measurements as the casing is run along the wellbore.
