Methods for identifying gas in a geological formation, in order to analyze geological formations, and NMR to analyze geological formations, and the system.System and methods for using measurements of T ~ 1 ~ nuclear magnetic resonance (NMR) for applications of LWD and MWD line wires and analyzers of NMR fluid hole well.The measurements of T ~ 1 ~ are characterized by insensitivity to motion, as the harmful effects arising from movement of the tool or fluid flow are reduced or eliminated effectively.Measurements of T ~ 1 ~ alone or in combination with other measurements of oil field pattern are shown to provide efficient data acquisition resulting in data sets with compact and robust.The potential for speed record increased significantly, and simple methods for the characterization of fluid, including direct and robust identification of gas.
