Z700® Marine Nodal System
The nodal design of the Z700® defines this revolutionary system. Each node operates autonomously, completely independent of all other nodes, recording cable-free and communication-free continuously for up to fifteen days. Z700 acquisition is a true two vessel operation, with one node-handling vessel and one source vessel. There are no restrictions on receiver intervals or the number of receiver lines deployed, perfectly suited for full azimuth surveys. When deployed, each Z700 node may be attached along a rope line, and easily recovered, analogous to the way fishermen retrieve long lines of crab pots.
FairfieldNodal's Data Acquisition Division will begin Z700® operations in 2009, expanding its non-exclusive seismic database in the Gulf of Mexico. The Z700® marine nodal system is also available for sale worldwide by the Systems Division of FairfieldNodal. Z700® specifications (PDF download)
