Abstract
Borehole NMR logging apparatus and methods. A multifrequency method using triple-wait-time is disclosed for determining gas- and light-oil-filled porosity over a broad range of reservoir conditions. The method improves the signal-to-noise ratio and the determination of T values for the hydrocarbons, especially when the reservoir contains different fluid types. A set of conditions is derived for the selection of optimum acquisition parameters for logging applications. The data acquisition and processing method enables accurate determination of the pore volumes occupied by each hydrocarbon phase as well as the pore volume occupied by water, as well as accurate T . A set of conditions is developed to aid in the selection of wait-time combinations appropriate for logging conditions.
