Seismic data acquisition is the first of the three distinct stages of seismic exploration, the other two being seismic data processing and seismic interpretation. The marine towed streamer survey was preceded by an acquisition feasibility, design and modeling study that used a variety of techniques. Sorry, preview is currently unavailable. Design of Acquisition Geometry for 3D Seismic Survey having Multiple Objectives . This is to certify that Mr. Kiran Kumar Talagapu, a final year student of M. Sc. The reflections from the subsurface are assumed to lie directly below the sail line that the seismic vessel traverses – hence the name 2D. Modern Seismic Data Acquisition could not have evolved without the digital computer.The late 1970's saw the development of the 3D seismic survey, in which the data imaged not just a vertical cross-section of earth but an entire volume of earth.
