New Technology Developments

Cordax continues to innovate and add services to the Logging While Tripping formation evaluation portfolio.

Resistivity Innovations

The latest Cordax advances include resistivity measurements that do not require a composite collar for acquisition as with the Dual Induction Resistivity. This new measurement includes Wave Propagation (PRT) which allows LWT acquisition in a full range of well bore conditions and formation salinities. Acquisition is from a steel collar sonde run in conjunction with the conventional LWT steel collar. The respective resistivity measurements are run in combination with the standard LWT measurements of Gamma Ray, Spectral Gamma Ray, Density and Neutron.

Wave Propagation Resistivity

The Cordax Wave Propagation Resistivity Tool produces electromagnetic (EM) waves which propagate on the outside of the LWT drill collar and allows a full steel collar triple combo measurement system for wells where composite collar acquisition is not suitable.

  • Measurements based on attenuation and phase shift of these EM waves at both 400 kHz and 2 MHz

  • Four depths of investigation, maximum 5 sec. sampling rate

  • Retrievable electronics deployed once TD is reached with data acquired on trip out of hole in combination with standard LWT measurements
