Title:
SYSTEM FOR SEISMIC SURVEYING OF A SUBSURFACE VOLUME
Document Type and Number:
WIPO Patent Application WO/2014/165219
Kind Code:
A3
Abstract:
Microseismic mapping using buried arrays with the integration of passive and active seismic surveys provides enhanced microseismic mapping results. The system is initially set up by recording signals in response to seismic energy with the buried array installation, while shooting a significant portion of the 3D surface seismic survey. The input analog signal at a sensor are amplified by a downhole gain and the amplified analog signal is sent to an uphole recording unit via a transmission line. The 3D surface seismic survey provides the following data: shallow 3D VSP data from the buried arrays; P-wave and converted wave data for the area covered by the buried array that benefits from a planned data integration processing effort; and microseismic data and associated analysis.
