Abstract

It is important to choose an acquisition technique and geometry, which produces minimum footprints. Uniform distribution of fold, offset and azimuth for all the bins will reduce the footprints to a great extent but it is not achievable in any 3D practical geometry. Achieving the uniform nominal fold and minimizing the variation of offset and azimuth sampling across the bins is also the prime objective of the designer in designing the 3D survey geometry so that the geometry creates minimum footprints.
