System and method for processing microseismic data

Abstract

A system () for processing microseismic data comprises an array () of seismic sensors () at known locations, means () for enhancing SNR in a seismic signal output from a seismic sensor, means () for detecting a microseismic event in the seismic signal and inverting means () for adapting a rock physical model () to microseismic data that are acquired at least partially from the seismic signal representing a microseismic event. The rock physical model comprises a set of spatial volume elements mapping a set of physical volume elements () within a volume () to be monitored, wherein each spatial volume element comprises attributes for the position and extension of the physical volume element (), a velocity and an attenuation. Data of various kinds, e.g. pore geometry, and from numerous sources, e.g. laboratory measurements, can be incorporated in the rock physical model ().
