Technology has proved its credibility by helping us to combat some of the most important challenges in decades. On a high interest, our yesterday's concerns are now our jubilations today. Also, various innovations that technology is offering our industry today have shown us clearly that the industry cannot afford to shuttle its today's cares until tomorrow. It is even more interesting that today creative minds in the industry are already gazing into the future, seeing about tackling our tomorrow's challenges right now. All these findings validate the simple fact that: 'the oil and Gas industry is a technology based and innovation driven' (David, 2011).The phase change and its adaptation are so rapid that if professionals fail to yield to it or feel reluctant to its tingle, they may find it hard to catch up with the transiting train. The thrust of the drive witnessed by the industry in the recent decade is intense. This is wholly responsible to the world's high demand for our commodity (Oil and Gas), our daily venture into the ultra-deepwater exploration, unconventional resource exploration systems which always beckon on new and strong techniques. All of these are enough to charge professionals to be aware of the demands of their fields by yielding their thoughts to the present breakthrough and preparing to face the next decade's challenges.
One important breakthrough that technology has offered the seismic data acquisition field of recent is the 'Nodal Seismic System'. The success is currently attracting a great deal of key players from every end of the industry and has kept discussions on over time. The advancement is also known as Cableless, Wireless or Nodal seismic acquisition system, as it may be. It is an improvement over the conventional cabled seismic acquisition system. An overview of this advancement in relation to the challenges it solves has been looked into in his article.

Textprobe:Chapter Problem Statement:
To quantify the amount of equipment required of a conventional cabled land system (and therefore what could potentially be eliminated by a cable-free system), let's analyse a typical 4,000-channel seismic acquisition system with receiver-station spacing of 30 meters (plus 10 per cent): Such a system would require 132,000 m. (132 Km) of in-line cable.
This cable would house telemetry twisted-pair wires and, in most instances, power wires. The in-line cable alone would weigh in at 6,000 Kg. Add in the geophone strings (33 m, each with six geophones) for another 132 Km of cable, weighing a bit over 15,000 Kg. Power for the line would typically require some 84 power stations at 58 Kg each for another 4,872 Kg. For our hypothetical 4,000-channel 2D line, we would require some 264 Km of cable and weigh in at around 25,872 Kg, or slightly less than 6.5 Kg, per channel. Add to this the fact that every receiver station would require three connections, two for telemetry/power and one for the sensor, and that each power station would need at least one connection, and the total number of connectors reaches over 12,000. That is a lot of equipment to protect and maintain, and this scenario does not even consider any cross-line requirements for 3D operations.
Even so, weight is not the only bothersome issue caused by seismic cables. Another is pure mathematics. There is either too much cable or not enough, and they must always be cut to specific lengths, or takeout intervals. If there is not enough cable, the project must be redesigned to accommodate the limits of the equipment at hand. If there is too much, extra equipment must be deployed to the field, so that the excess cable can be piled or coiled between receiver stations, which creates an environmental and operational burden, and can lead to seismic noise problems due to leakage.
To further complicate matters, cables are easily damaged by natural and cultural causes, and connectors

wear out. When that happens, the field crew must often cease production to repair or replace the defective cable(s) and connector(s). Troubleshooting the spread becomes an ongoing challenge, which means that even when a seismic crew is not acquiring data, they are still costing money. Lost production is lost time, and lost time is lost money.
Again, the good news is that the burdens created by cables may soon be a thing of the past. The modern seismic contractor finally has options that simply were not available even just a few years ago. Currently, there are a number of 'minimal cable' systems commercially available. These systems do not require cables to interconnect the individual seismic data acquisition units to a central recorder. As such, they are somewhat similar to radio telemetry systems of the past; in fact, some use radios to transmit quality control data to a central station or field data collection reader and, therefore, may require a radio license. While these 'minimal cable' systems do indeed eliminate the need for any telemetry cable, they still require cables to interconnect the individual pieces of equipment, such as a battery and sensor(s) to a remote unit. These connection cables, however short, are still prone to the same hazards as the conventional seismic cables of the past.
THE MECHANISM DEFINED:
The scope of this seminar would broadly divide the cable-free seismic data acquisition systems into two types based on their mechanisms, namely:
1. Wireless Geophone Network.
2. Autonomous Nodal System.
The Mechanism defined:
A system that acquires seismic data using cellular wireless technology is similar to a cellular telephone system in a large city. Inside the hypothetical city limits, several radio towers create overlapping reception/broadcast areas that combine to cover the city. Through a connection of radio towers, a cellphone user at A can talk to B, or transmit digital information to, a second cellphone user at B., The diagram impli
