Systems and methods for analyzing geologic formations using nuclear magnetic resonance (NMR) T1 and T2 measurements. In the systems and methods, a first set of T1 NMR measurements of the geologic formation are obtained. Further, at least one second set of T2 NMR measurements of the geologic formation are obtained. The first and at least one second sets of NMR measurements are then processed to derive an estimate of one or more of: diffusivity, gas to oil ratio (GOR) and viscosity at reservoir conditions, wherein the estimate is obtained from the T1 NMR measurements and the T2 NMR measurements as a function of T2,hc, T1,hc, G, TE, where G is the gradient of the magnetic field and the T1 NMR measurements are used to approximate T2 NMR measurements with an infinitely short T E. |
