Headquartered in Aberdeen, UK, TenzorGEO was founded with the aim of maximising economic recovery of hydrocarbons in the North Sea by utilising a unique interpretation software and methodology not previously applied in the offshore domain. The company leverages on decades of experience acquired up by our passive seismic specialists and a high success rate across numerous subsurface applications.
Since its formation, TenzorGEO has continued to push boundaries, expanding into new industries. In 2020, TenzorGEO established itself in the Carbon Capture and Storage industry by upgrading its proven interpretation software to meet the requirements of CO2 injection monitoring.
The History of Low Frequency Seismic Technology
The history of TenzorGEO’s Low Frequency Seismic (LFS) technology is unique and highlights the importance of rediscovering valuable knowledge from the past, before it gets swept away by the tides of time.
Historically, the Institute of Physics of the Earth at the Russian Academy of Sciences was the global leader in geophysical research, well-funded for political and military reasons. Following the collapse of the Soviet Union in the early 1990s, the funding and support for the research was drastically cut back. Although the concept of LFS remained strong, any research of this nature required a substantial outlay of resources: large data sets for experimentation, high-level academics to create algorithms and software, a high-power supercomputer, and the recognition of the method viability from the petroleum industry. None of this was available during the years of the post-Soviet upheaval.
The advance and commercialisation of any technology requires massive investments and support of industry supermajors. LFS method was shelved, as major operators focused mainly on tactical improvements and were unwilling to change their processes, regarding it as an unnecessary risk.
By the time LFS attempted to make inroads into the Russian market, active seismic has already become the dominant method for exploration and appraisal and breaking into the market proved difficult. Mainstream beliefs that shorter waves (higher frequencies) were more informative turned most of key industry players away from LFS.
Currently, discovering conventionally structured reservoirs is becoming increasingly rare. Remaining assets are located in complex geological hydrocarbons traps, where the application of conventional seismic is less effective and significantly more expensive. Complex geology requires full wave inversion and complex mathematics, two challenges where LFS truly delivers.
For some time, LFS technology seemed to have been lost. It was revived by Professor Evgenii Birialtsev, the father of the methodology, who persuaded the Russian supermajor, TatNeft, to use it. Having secured the funding, the obstacles mentioned earlier were overcome and LFS was successfully used and developed over the past 14 years on shore. Three years ago, Professor Birialtsev co-founded TenzorGEO to begin a new chapter in LFS innovation. Today, the LFS methodology is applied in offshore environments using the bespoke German subsea robotic technologies
