By Technology

For TenzorGEO, it all started with academics who had a vision, a group of physicists with a background in passive seismology research. Looking to commercialise their work, they researched how their expertise in low frequency seismic studies could be applied  to locate hydrocarbon reservoirs. It was a very challenging task because they were ahead of their time: the concept of Big Data, large libraries of data to play with, and supercomputers powerful enough to perform complex calculations were yet to come. Equally importantly, the oil and gas sector had no understanding or faith in the technology and subsequently there was no demand for it.

By the time the first commercial passive seismic technology came to the market in the early 1990s, conventional active seismic has already become the dominant method for hydrocarbons exploration and appraisal. Prevailing beliefs were based on the subsurface ray theory in optical geometry narrative. The mainstream idea that shorter waves (higher frequencies) were more informative, and high oil prices put pressure on most players to continue using tried and tested methods, instead of exploring an innovative but unfamiliar passive seismic technology.

Despite the setbacks, the LFS technology eventually received funding from a Eurasian supermajor in 2000s, which allowed its developers to accumulate the field data from the growing base of clients. Slowly but surely, the technology gained traction and market acclaim due to its very high success rate, ease of application and moderate cost.

Over the years, as experience of the team grew, and more data was collected from the field, it was decided to extend the application of the passive seismic to monitoring of microseismic events, either induced or naturally occurring, and the Full Waveform Location technology was brought to the market. Both technologies were successfully deployed in hundreds of onshore projects, and in 2018 TenzorGEO decided to extend their application to offshore sector worldwide.

Whilst both of TenzorGEO’s passive seismic technologies deliver high success rate, ease of application and moderate cost benefits to our customers, the methods are very different in nature and address a wide range of tasks in a range of industries. Please click below to learn more about our technologies in more detail.



We provide Full Wave Location passive seismic services to determine and manage risks and opportunities associated with faults, fractures and fluid injection. Using technical expertise, advanced passive seismic methodology, sensory equipment, computer simulations and quantitative methods, we identify, evaluate and resolve your subsurface characterisation challenges.
TenzorGEO supports your exploration and development activities with passive geophysical survey services for all water depths and onshore environments. We perform surveys of the subsurface from small pools to established fields in order to reduce risk, enhance ROI and facilitate well planning and design.

Information means information in any form (including, without limitation, methodology, software and computer outputs) which is not excluded under clause 4 below, whether written or oral, of a business, financial or technical nature which is marked or otherwise indicated as being or is, or ought reasonably to be, known to be confidential and which is disclosed by one party to this Agreement (the Disclosing Party) or any member of its Group to the other party (the Receiving Party) or any member of its Group or otherwise come to its attention during the parties’ involvement in the Business Purpose. Information includes information relating to the involvement of either party’s Group in the Business Purpose.

1. The Receiving Party agrees:

(a) to hold the Information in confidence and, not without the Disclosing Party’s prior written consent, to disclose any part of it, to any person other than those directly concerned with the Business Purpose and whose knowledge of such Information is essential for such purposes.

(b) not, without the Disclosing Party’s prior written consent, to use the Information for any purpose other than the Business Purpose;

(c) to delete from any device containing any Information and/or return to the Disclosing Party upon demand the Information except for one copy of such Information as is required to be retained by law, regulation, professional standards or reasonable business practice by a member of Receiving Party’s Group; and

(d) to use reasonable endeavours to provide the Disclosing Party with prompt notice if any member of the Receiving Party’s Group becomes legally compelled to disclose any of the Information, so that the Disclosing Party may seek a protective order or other appropriate remedy. If such order or remedy is not available in time, the obligation of confidentiality shall be waived to the extent necessary to comply with the law.

2. The Receiving Party agrees that no right or licence is granted to the Receiving Party’s Group in relation to any part of the Disclosing Party’s Information.
