When acoustic (sound) waves are broadcast through the formation, the time taken for the waves to travel a fixed distance is measured. The velocities at which the various wave types travel are related to the properties of the formation and the fluids within. These velocities can be used for porosity estimation, elastic moduli, fracture detection, lithology determination, and well-to-well correlation.

This data can also be used in drilling applications (e.g., pore pressure determination, rock strength calculations, and borehole stability analysis) and in geophysical applications (e.g., time-to-depth, seismic correlation, synthetic seismogram, and AVO analysis).

High resolution images of the borehole can be used to identify a variety of geological attributes such as structural dip, faults and fractures. These images can also provide insight into the condition of the borehole, stress and rock mechanics around the borehole and assist in porosity determination.

Halliburton provides a suite of solutions for operation in water-based or oil-based muds.

With sidewall coring, numerous undistorted core samples can be easily acquired in a single run providing samples for a range of petrophysical testing and analysis.
