Exploring old basins for the Future 


As society’s appetite for energy grows and changes, areas that were once in oil and gas production are receiving new attention. The use of Heliometric data is constantly growing in studies of old basins boosting their attractiveness as a destination for investment in resource exploration. 

Actual Geology is tasked with gathering new Heliometric data concerning potential oil, gas, helium, geothermal and natural hydrogen resources concealed beneath the surface. This new data supports exploration activities by providing a better understanding of the basin and assisting in identifying geological terrains with resource potential and for future data collection and exploration opportunity. 


The Heliometric data collection program is built on previous  seismic data and decades of scientific research undertaken in the regions and involves extensive pre-study to identify optimal survey measurement step and directions of Profiled 2D helium survey

The processed Heliometric data presents a geological opportunity summary of the region with a major output - Regional 2D Heliometric anomalous map. This map provides a baseline of geological knowledge, a possible extent of the old basins, discovery of new basins and recommendations for future studies in the region only within highly prospective areas.

Based on Heliometric data the new seismic data will be planned over highly potential zones providing an improved understanding of the the region geology, basement architecture, the stratigraphy and the structural evolution of selected prospective areas.


G+G+He data integration aims to greatly improve resource evaluations, further de-risks exploration within known basins and positions countries/regions for future exploration investment.

Old basins are new again

  • Evaluate the region for conventional and unconventional oil and gas, helium, natural hydrogen and geothermal resources;

  • Understand the relationship between regional Heliometric data and available old G&G data and existing wells;

  • Evaluate the undercover lateral extent of the objects imaged in the old seismic data;

  • Understand the nature of the fill in the major structures;

  • Improve understanding of the stratigraphy across the region investigating the structures and basins in more detail with the existing G&G data and new heliometric data;

  • Plan the extension of  the seismic dataset over zones selected by Heliometric data;

  • Investigate the generation, migration and accumulation of deposits by extensive modelling by use of Heliometric data;

  • Confirm stratigraphy by drilling of stratigraphic wells in locations de-risked by Heliometric data.
