<p num="1"><br/>System and methods for using nuclear magnetic resonance (NMR) T1 <br/>measurements for wireline, LWD and MWD applications and down-hole NMR fluid <br/>analyzers. The T1 measurements are characterized by insensitivity to motion, <br/>as the <br/>detrimental effects arising from tool motion or fluid flow are effectively <br/>reduced or <br/>eliminated. T1 measurements alone or in combination with other standard oil <br/>field <br/>measurements are shown to provide efficient data acquisition resulting in <br/>compact and <br/>robust data sets, the potential for substantially increased logging speeds, <br/>and simple <br/>methods for fluid typing, including direct and robust identification of gas.<br/>
