"Method of investigating a region of reservoir in a training subterru00e1nea".A method of investigating a region of reservoir in an underground formation by a seismic survey by lapse of time.The underground formation comprises a region of additional training adjacent to the region of the reservoir,The method comprises the steps of obtaining data from a seismic survey for the period of time including seismic data from underground formation at a first point in time and at a later point inWhile, process the seismic data to obtain a seismic representation of change in a predetermined seismic parameter in the region of additional training.The seismic parameter is dependent on voltage; interprets the representation change in seismic and seismic parameter in the region of additional training for an indication of changes in the distribution of youS in the region of additional training; and deriving a property of the region of reservoir using the indication of change of stress distribution in the region of additional training.
