Superior Borehole Images in Highly Resistive Formations
This electrical wireline borehole imaging tool is designed to obtain superior quality images even in high Rt:Rm environments.
The expanded operating range of the XRMI™ tool over conventional electrical imaging tools is achieved through its new, state-of-the-art, 32 bit digital signal acquisition architecture combined with a large increase in available power for the excitation current (EMEX).
As a result, the signal to noise ratio of the raw measurements is improved by a factor of up to five, and the dynamic range is expanded by a factor of up to three.
The resulting images offer superior fidelity, even in highly resistive formations
(Rt > 2000 ohm-m) or relatively salty borehole fluids (Rm < 0.1 ohm-m).
