Sonic logs form part of most well log acquisitions, and support a wide range of interpretation applications, from simple porosity and travel time estimations to more complex geomechanical properties studies, anisotropy and shear studies, and permeability estimation.

Sonic processing is often performed by the acquisition contractor.  This adds extra cost and can also prevent end users from applying different filters, correcting possible defects, or even performing additional workflows that may not have been covered by the original budgeted logging and processing program. An example might be sonic anisotropy analysis from an acquired cross dipole.

Geolog solves this problem by providing a vendor-independent, full waveform sonic processing capability, that supports every tool on the market.  This module contains a full set of tools for pre-processing and processing sonic data, allowing the user to obtain the best semblance and picking possible.  A full workflow for sonic anisotropy is included with the application, allowing you to evaluate energy, slowness and travel time anisotropies, in order to completely understand the anisotropy around the borehole.
