Abstract
In this paper, we present an integrated procedure for estimating hypocentres and complex 3D velocity models by the joint traveltime inversion of micro-earthquakes and active surface seismic data. Reflection tomography can reconstruct the major formation interfaces along extended areas, but its vertical velocity resolution between interfaces is low. Micro-earthquakes may improve the ray illumination at the reservoir, so improving in sequence the 3D velocity model and their location precision. This data integration improves also the time origin estimation of micro-earthquakes.
