摘要： Multicomponent measurements made in a cross-bedded earth formation are processed to give one or more equivalent TI models. Resistivity information about the cross-bedding is obtained from one of the TI models and a measured cross-bedding angle. Resistivity information about the cross-bedding may also be obtained using a combination of two or more of the equivalent TI models.

摘要： In one method, the permeabilities are obtained by correcting the geometric factor derived from combining the FRA analysis and buildup analysis. In a second method, the permeabilities are obtained by combining the spherical permeability estimated from buildup analysis and the geometric skin factor obtained from history matching the probe-pressure data. In another method, horizontal and vertical permeabilities are determined by analysis of pressure drawdown made with a single probe of circular aperture in a substantially horizontal borehole at two different walls of the borehole.

摘要： Spin echo signals measured with a multifrequency NMR logging tool are analyzed to determine if one or more of the regions of examination associated with each of the frequencies has signal contamination from borehole fluids. A variety of different methods can be used for analysis. Corrected spin echo signals can be obtained and processed to give improved estimates of formation parameters.
