A US company is proposing a new wireless technology to collect seismic data in real time. This innovation, which is more flexible, faster, cheaper and more ecological, is helping to make the collection of essential seismic data more reliable and accessible.Geological exploration plays a critical role in the decision to drill into the subsoil to reach hydrocarbon resources. This phase must answer questions about whether the conditions are favourable to the formation of hydrocarbons, the types of rocks in the subsoil or the possible migrations between hydrocarbons and the possibility of using them.Geophysicists draw up maps of the onshore or offshore subsoil using sound vibration or compressed air techniques. Along the lines of a radar, the nature of the returning waves can be used to produce a multi-dimensional image.
The wireless revolution
Wireless Seismic proposes an innovative solution in this domain. Founded in 2006 by a group of exploration and production researchers, the company set itself the target of revolutionizing terrestrial seismic imaging with an advanced technology: the first wireless seismic data acquisition system to collect data in real time.
RT 2 is the only wireless system capable of instantaneously collecting millions of units of seismic data without any physical intervention of any kind.
Wireless technology provides operators with significant benefits on almost every kind of terrain: wetlands, ecologically sensitive terrain, fields and other zones that are difficult to access.. All this without any significant infrastructure, material or human intervention: a fact that makes for faster and cheaper deployment that is much safer for operators.
As Mick Lambert, President and CEO of Wireless Seismic, declared at the implementation of the RT 2 system technology by YNG (Yug-Neftegaz Private Limited) as part of a project to collect seismic data in Turkmenistan, "Companies all over the world continue to recognize the benefits, the efficiency and cost savings that the RT 2 system has brought to their seismic acquisition projects, and its flexibility when it comes to environmental questions".
This technology, which is more precise and faster, is of interest mainly to oil and gas companies, the mining industry and geothermal activities. The RT 2 system could also prove to be very useful in the prevention of earthquakes, even if this type of application has not yet been tried out.
Wireless Seismic is supported by Chesapeake Energy Corporation, one of the leading users of seismic data in the United States, Energy Ventures, an independent venture capital company that invests in the oil and gas sector, and Total Energy Ventures, the development capital subsidiary of the Total Group.
For Christophe Tonion, who is managing the Wireless Seismic file for Total Energy Ventures, "Wireless technology is quickly becoming the standard for terrestrial seismic acquisition. Real-time wireless technology represents the next generation of systems that will spread the savings we have already verified in certain configurations to the majority of applications, and will extend the use of wireless solutions to high-density campaigns involving very high numbers of receivers capable of producing very high quality images."
Wireless Seismic's innovation can be used in campaigns in complex zones, without damaging the environment and without having to use heavy machinery, while eliminating the operational risks to men and equipment and producing images of an exceptional quality at a reduced cost. "This really is 'Better Energy' and it is the future of seismic measurement," concludes Christophe Tonion.
