摘要:
Apparatus and method for determining the location of the source of seismic energy around a well are provided. Multiple seismic receivers, each receiver having orthogonal seismic sensors, are axially spaced on a tool which is capable of sending real-time seismic signals to the surface over conventional wireline. A method for calculating the location with respect to the receivers is also provided, the method employing data from all the sensors and a performance function to minimize error in the determination of location, and a simplified method is provided for determining if a fracture has extended past a selected depth in a formation.
