Squeezing more out of 2D seismic data: Processing and interpretation of a pseudo-3D seismic survey from New Zealand

J. Helen Isaac and Don C. Lawton


During the acquisition of seismic data near Christchurch, New Zealand, in 2011, some receivers along a 2D line were left live to record data from sources located on an orthogonal 2D line. We created a pseudo-3D seismic survey from these data. We processed the data somewhat unconventionally to remove shot-generated noise and stacked it into bins having the same dimension as the receiver spacing in order to increase the fold. We interpreted faults on the pseudo-3D data and were able to update the regional fault trend interpreted previously using 2D data integrated with regional mapping.
