Abstract

A core analyzer includes a test cell containing a core of earthen material. The core has a length suitable for monitoring fluid moving through the core. Apparatus provides at least two fluids to the test cell in such a manner that a first fluid fills the core in the test cell and a second fluid displaces at least a portion of the first fluid. Other apparatus uses nuclear magnetic resonance to monitor the saturation of the core with the first fluid and to monitor the displacing movement of the second fluid.
