Sonic Measurements for Porosity and Geomechanical Properties
Acoustic, or sonic, tools measure the integral traveltime (Δt) of the formation in a variety of environments. In hard-rock sediments, acoustic logs recognize secondary, or vugular, porosity. Run in conjunction with density and compensated neutron tools in bad borehole conditions, acoustic logs measure porosity, and this third measurement of porosity is also used to identify complex lithology. Sonic tools can measure shear velocity, which is useful in understanding rock mechanical properties.
Understand acoustic behavior in and around the borehole with accurate monopole and dipole measurements made axially, aximuthally, and radially of the stress-dependent properties of the near-wellbore rocks for full geomechanical modeling.
