Patent Number Title Of Patent Date Issued
4692707 Method and apparatus for measuring the earth formation resistivity of a plurality of radial regi September 8, 1987
A wall engaging pad for well logging comprises a face portion of electrically conductive material within which are disposed three or more current electrodes. The survey current emitted from the current electrodes is differently focussed. A suitable current return is furnished. A plur
4622855 Low thermal response time surface acoustic wave sensors November 18, 1986
Disclosed is an externally loaded pressure sensor using a pair of SAW devices formed on the wall of an interior cavity. The difference frequency of these devices is used as a temperature-compensated measure of hydrostatic pressure on the sensor exterior. The termal response time of t
