Overview
The OILTIO EM propagation resistivity LWD measures formation resistivity in real time based on amplitude attenuation and phase shift between receiver antennas. Tools are available in 6-3/4″, 4-3/4″ and 3-1/2″ outer diameters with 6-transmitter/2-receiver, 4-transmitter/2-receiver and 2-transmitter/2-receiver antenna configurations, rated to 150 °C / 175 °C.
