terms:microspherically_focused_log
A microresistivity log produced by a tool of the spherically-focused type which has electrodes mounted on a sidewall pad which is pressed against the drilled formation. Because of the kind of focusing method used, the tool gives improved flushed zone measurements over those made from microlaterolog- and proximity log-type tools. Mud cakes with thicknesses up to 3/4 in. have little effect on the measurements of the microspherically focused tool; and, resistivity measurements are made from the region just behind the mud cake where the flushing is most effective. A caliper curve usually is recorded simultaneously.
