A brief history of a disruptive nodal technology
Seismic systems have traditionally used cables to transmit the data from the sensors to a central system. Lately, nodal systems have been introduced, where the data is recorded internally in a battery powered sensor node. Removing the cables can make operations vastly more efficient, however the large size and weight of the current nodes, and their cost, have limited the operational benefits and made it difficult to increase the channel count. We present a new nodal system that overcome these issues. It was originally developed to make high density seismic possible and affordable for the oil and gas industry, and has been successfully tested in different environments.
