Feasibility of Cross-well Hydrofracture Monitor by Accurate Numerical Simulation of Seismic Waves Propagation through Mu

In this paper we present full scale numerical simulation of cross-well observations for shale gas exploration. The main technology used in production is based on hydro fracturing, however it is reported as a rule only about 20% of fluid used for fracturing gets back. Thus some fluid remains in the fractures blocking them from gas penetration. On the base of the full scale numerical simulation the principal ability to use time-lapse 3C cross-well observations in order to recover extremely fine variations of the background, including movement of watering zone was shown. Moreover strong diffraction was observed from the gas-water contact which allows to exploit intensively developed approaches of diffracted/scattered waves elimination and imaging to recognize the movement of the contact.
