Increasing the resolution of vsp ava analysis through using borehole gravity information

摘要

An apparatus and method for estimating at least one parameter of interest for an earth formation by reducing an uncertainty in seismic parameters using density information. The density information may be acquired from borehole gravity information. The method may include inverting seismic parameters while using density information obtained from borehole gravity information. The method may also include joint inversion of seismic parameters with density information. The apparatus may include a gravimeter and a processor configured to estimate the parameter of interest using the seismic parameters and density information.
