Acquisition Design of the First 4 Component 3D Ocean Bottom Seismic in the Caspian

B003 Acquisition Design of the First 4 Component 3D Ocean Bottom Seismic in the Caspian Summary 1 The signal to noise problems inherent in towed streamer data associated with mud volcanoes subsurface heterogeneities and distributed gas in the Azeri and Gunashli structures of the Caspian sea prompted the use of three dimensional four component ocean bottom seismic (3D/4C OBS) to improve imaging. The introduction of several innovative enhancements to the traditional ocean bottom cable technique when applied cohesively across both acquisition and processing resulted in cost savings compared to conventional OBS acquisition and improved final data quality compared to towed
