MHAC Tool brochure
MHAC is capable of measuring the propagation characteristic of acoustic wave in borehole,used to estimate porosity and evaluate the cement bond quality.
MHAC MHAC is comprised of a single transmitter and five receivers. The full waveforms are recorded and compressed by MHAC.STC is used to calculating travel time.In OH mode MHAC provide DT curve,in CH mode it provide CBL、VDL curves.
