Summary:
This paper discusses the application of imaging and characterization in the local angle domain (LAD) in a shale reservoir. The system delivers high-quality images of the reservoir and geomechanical characterization of rocks with the precision needed to steer horizontal drilling, detect sweet spots, locate geobodies resistant to fracturing, or image geobodies of irregular shape. This technique is particularly attractive in Poland, where conventional seismic imaging in complex tectonics has frequently resulted in dry wells. Using this method, and combined with well data, image horizons were accurately tied to well markers, and stress/fracture orientations were highly correlated in the vicinity of the wells.
