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.

  • Continuous temperature and pressure log. 
  • Mud integrity log. 
  • Independent wireline jar firing and re-cocking record. 
  • Independent record of all sticking events. 
  • Cable creep analysis for optimising formation testing. 
  • Cable torque log for stranding risk analysis.
  • Loss and influx zone identification. 
  • Wellbore transients during clean-up and sampling. 
  • Casing collar locator (CCL) log from magnetometer.
  • Cased hole contact log for predicting wireline wear zones.
  • For a more accurate interval mud weight, 2 WXSOs can be run simultaneously.


WXSO Report

A comprehensive written report on all the WXSO data acquired on the logging operation.  Includes time and depth logs, station logs, temperature, mud weight, cable rotation and creep analysis, plus analysis of any sticking points encountered on the job.

Temperature Analysis

Analysis of temperatures from the WXSO's continuous-reading external temperature sensor. This includes an extrapolated borehole temperature if multiple logs are run.

Cable Creep Analysis

Analysis of cable creep for station logs using the WXSO accelerometer. Creep distance is calculated for each station, and the planned and actual depths are plotted against the GR log.
Actual depths can also be used to improve pressure gradients.

Event Visualisation

Events can be played back as an animation to show cable spin, jar firing, cable creep, stuck tool situations and more.
