Talk Description
“Wireless Progresses!” Roy Kligfield (CEO)& Mick Lambert (COO)--Wireless Seismic, Inc.

The application of wireless technology to the oil industry has substantially lagged behind its adoption in the cellular telecommunications industry. Wireless technology is best known to consumers through the success of GSM and CDMA air interface protocols and networks to serve hundreds of millions of users throughout the world with a reliable and scalable service offering. Land seismic acquisition, however, has traditionally relied on the use of cables to power the acquisition instruments, and to transport the seismic data to a central location through cabled telemetry protocols. Land seismic acquisition has long been handicapped by the logistical issues relating to the use of cables to connect acquisition instruments. The problems of deploying and maintaining cabled networks, re-locating cables in order to move the spread, repairing cables—have acted as constraints on the growth in size and scope of land seismic acquisition projects worldwide.

In the recent past, two approaches are being adapted in order to overcome these barriers: First, instruments are being deployed as “dumb” nodes whose data has to be collected, harvested and transcribed in order to make it ready for processing; and second, instruments are being deployed with the capability to wirelessly transport the seismic data to a central location in real time. Whereas the nodal approach has been successful at eliminating the use of cables, it unfortunately introduces the need to visit the instruments physically, to collect (harvest) the data from the instruments, and to prepare the downloaded data (transcription) for input into industry standard formats. And most notable of all, the nodal approach precludes any chance of viewing the seismic data itself (not just the quality control parameters of the data) in real time—one of the major advantages of using a cabled system.

Wireless Seismic has introduced a solution to the marketplace that both eliminates the cables while preserving the real-time nature of the seismic data collection, and doing so with an architecture that is designed to scale-up to very high channel count systems. This presentation reviews the initial results of field deployments using this architecture in both remote and urban environments. A review of some of the system capabilities and limitations in terms of network throughputs, radio interference issues in urban environments, and the use of different sources will be given. Based on its initial deployments, it is believed that the solution is entirely capable of being scaled up in the near future to support the large channel counts demanded in land seismic operations.
