The global acceptance of recording nodes in seismic operations is gradually increasing. Many regions of the world have either switched or are in the process of transitioning to nodal operations. Several factors have encouraged this transition among seismic contractors and their respective clients. High among these factors are cost of operations, flexibility of operations in a variety of terrain types, higher HSE requirements of field personnel, changes in the methods of acquisition and the demand for higher density shooting and single sensor recording. In Canada and the United States, the transition to nodal operations for seismic data recording is nearly complete. Whereas, adoption of nodes on the very large-scale projects of the Middle East and North Africa is in its infancy. This is partially due to the existence of enormous volumes of cable equipment in the inventories of seismic contractors but is also due in part to the fact that these projects span many years of continuous operations. The motivation to increase the recorded trace density while decreasing HSE exposure, cost of operations and environmental impact is driving new interest in nodal operations on large-scale projects. Nodes promise to positively impact many if not all of these motivational factors during this transition.
