We are the developers and masters of Marine Heliometric data acquisition, processing, and interpretation


Many in the scientific community point out that Aquatic Helium survey is characterised by technical complexity of detecting Heliometric anomalies and the high probability of obtaining erroneous results.

In the late 1990s, we began with research work on rivers and lakes to check if it was possible to obtain a high quality of Aquatic Heliometric data. After much trial and error during the course of extensive research, we have come to the conclusion that such work can only be done using our own methodology, on our own automated highly sensitive equipment and by our own teams with sufficient experience.


Our company entered transit zone surveying in 2014, thus commercialising the technology.

In 2019 results of Offshore Helium survey in transit zone were proved by the first offshore discovery in the Sakhalin Island. Since 2018, we have been surveying deeper waters, showing that our Offshore Heliometric technology successfully predicts offshore drilling outcomes.

Our Aquatic Helium surveying technology produces a Heliometric dataset that perfectly describes geological objects and can be easily integrated into other available geological and geophysical information.

To date, no team in the world has been able to do such a job as successfully as Actual Geology.

The success rate of using our Heliometric technology to predict offshore drilling results is stable at about 90-100%, which is unmatched by any other technology in geology.

We have completed the world's largest Offshore Helium Survey and proved to international scientific society that helium imaging can produce excellent results and is a powerful tool in evaluating promising traps and structures, as well as effectively reducing the risk of offshore drilling.

  • Helium concentrations measured "as we go" in-situ, without any delays and transport of probes 

  • Grid step selection takes into account targeted geological objects

  • Onboard systems are fully automated 

  • Superior precision and quality of measurements, no need to return for re-taking the measurement

  • Data interpretation and processing based on mathematical and physical algorithms

Rivers and Lakes

Years of practise have shown that surveying Helium gas on water is a complex process, as any slight error in sampling can lead to inaccurate results. Taking into account the many factors involved in data collection on the water, we have developed our own methods and portable measurement systems, which give us confidence in the quality of the data collected.

Transit Zones

The solution to the problems of seismic surveys in transition zones is possible by applying our innovative technology for acquiring Heliometric data in transition zone before seismic data acquisition to identify the most promising zones for hydrocarbon discovery. Based on Heliometric data further seismic works will be planned only over areas with the highest hydrocarbon potential.

Shallow waters

The large amount of research (with more than 10,000 analysed water measurements) that has been completed by our team during the past years has done much to clarify the understanding of heliometric data in the shallow waters and provided our team with unique experience in interpreting offshore heliometric data.

Mid and Ultra-Deep waters

Taking into account a growing interest of Petroleum Operators in deeper waters, Actual Geology has developed special solutions for Helium Surveys with water depth from 300 meters and upwards. To sustain a high speed of operations, we use unique water sampling submersible carriages that moved below the current and collect water samplers. At the same time we apply high speed automated helium measurement systems to identify helium concentrations in water "as we go".
