More Information
Summary:This invention relates to investigations of rock samples, and more particularly relates to nuclear magnetic resonance (NMR) methods for determining characteristics of a fluid in a rock or earth formation. Nuclear magnetic resonance methods for extracting information about a fluid in a rock are described. A system of nuclear spins in the fluid are prepared in a driven equilibrium, and a series of magnetic resonance signals generated from the fluid. The series of magnetic resonance signals is detected and analyzed to extract information about the fluid in the rock.
