Intelligent Cross Dipole Sonic Tool (iXD)

Download Spec Sheet

The Intelligent Cross Dipole Sonic Tool, combining monopole and crossdipole sonic technology, provides a detailed acoustic representation of the formations surrounding the borehole including horizontal and challenging well profiles. The information acquired is vital for geomechanical analysis, wellbore stability, and production enhancementtreatment design. Sonic anisotropy and the orientation of the anisotropy can be used to determine the orientation of natural fractures.

LOGGING APPLICATIONS:

  • Porosity estimation
  • Anisotropy and stress evaluation
  • Natural and hydraulic fracture evaluation
  • Field development optimization
  • Formation and resevoir characterization
  • Stratigraphic correlation
