WXSO - digital cable standoff

The world's first cable-mounted data package.


WXSO is the result of Gaia’s ongoing R&D into wellbore and cable dynamics (drag, creep and torque) and future conveyance technologies.  It can be considered a “black-box” for a logging run.

The WXSO features a memory gauge with pressure, temperature, accelerometer and magnetometer measurements, with a fast sample rate (32ms).


Uses for WXSO:
• Continuous temperature and pressure log.
• Mud integrity log.
• Independent wireline jar firing and re-cocking record.
• Independent record of all sticking events.
• Cable torque log for stranding risk analysis.
• Loss and influx zone identification.
• Wellbore transients during clean-up and sampling.
• Measurement of well fluid depth.
• Casing collar locator (CCL) log from magnetometer.
• Better estimation of cable creep for optimising formation testing.
• Cased hole contact log for predicting wireline wear zones.
