Trials of Autonomous 4C Nodes in Deep Waters

A14 TRIALS OF AUTONOMOUS 4C NODES IN DEEP WATERS. Pierre-Yves Granger(1) Michel Manin(1) Anne Rollet(1) Jean-Luc Boelle(2) Enrico Ceragioli(2) Frederic Lefeuvre(2) and Emmanuel Crouzy(3) Abstract 1 During the summer of 2004 an experimental OBS survey was acquired and processed by CGG over the Girassol field operated by Total Angola offshore West Africa. Five ARMSS (Autonomous Reservoir Monitoring Seismic System) nodes were deployed in this area at a water depth of 1300 meters. The primary objective of this trial was to verify the operational sequence and performance of this new generation of 4C recording equipment. There were also a number of
