METHOD AND APPARATUS FOR FORMATION EVALUATION AND BOREHOLE SIZE DETERMINATION
摘要
The quality factor of a NMR-antenna depends upon mud conductivity, formation resistivity and the borehole size. The Q of the antenna is measured. From measurement of one of formation conductivity or borehole size, the other can be determined.
