We use a new age state-of-the-art geochemical practice to find low-carbon natural hydrogen
NATURAL HYDROGEN EXPLORATION
About Hydrogen
-
Hydrogen is the first element in the periodic table
-
The lightest, most abundant and one of the oldest chemical elements in the universe
-
Hydrogen is the main component of oil and natural gas in terms of the number of atoms
-
Hydrocarbon compounds were generated when the streams of hydrogen pass through carbon and form an extensive system of pores and caverns
-
Hydrogen migrates from the bowels of the Earth in two main forms: free gas - H2 and in the form of silicon-hydrogen compounds - silicides
-
The Earth’s atmosphere contains 2.5 billion tons of hydrogen, which escapes into space «at a speed» of about 250,000 tons a year.
-
A permanent source of hydrogen is the degassing of the earth directly
Hydrogen + Helium Subsoil Gas Surveys
-
Helium spatial anomalies on the surface define hydrocarbons, hydrogen, helium, geothermal reservoirs/resources, uranium deposits, active faults and high permeability zones
-
Hydrogen has ability to accumulate in natural gas deposits together with other gases - hydrocarbons, nitrogen, carbon dioxide, helium.
-
The high migration ability of both hydrogen and helium makes it even possible to migrate out of the reservoir through effective sealing and form a hydrogen and helium concentration field above the background value on the surface. Moreover, both gases migrate through zones of increased permeability (deep faults) from the depths of the earth to the surface (deep degassing).
-
The zonal surveys of hydrogen concentrations carried out on the surface of the gas fields show that Helium anomalies are accompanied by an increase in hydrogen concentrations: the zone of increased hydrogen concentrations conforms to the zone of the helium field and in areas without helium anomalies, hydrogen concentrations have also not been established.
-
This H2+He method will help quickly identify hydrogen + helium anomalies in-situ (on-site), build up correlation between hydrogen and helium anomalies, sort out hydrogen anomalies that can be associated with biogenic (organic) hydrogen and integrate processed data with available G&G data.
-
As the result of work, priority wells for hydrogen drilling are recommended and zonal objects associated with geological structures (traps) with good reservoir properties and an effective seal will be preferable.
H2+HE SURVEY STAGES
1) Processing of Earth Remote Sensing data, Seismic data or other available G&G data
Processing of remote sensing data and other data in the license block will make it possible to identify structures on the earth’s surface - potential zones of discharging gas flows - linear and ring structures.
2) High-precision ground Hydrogen + Helium survey
High-precision, ground-based H2+He survey is carried out on the territory of promising areas identified at stage 1). It is carried out by automated dual gas detection systems (produced by Heologic).
As a result of the survey, anomalies of hydrogen concentrations are revealed and mapped - projections of zones of increased permeability and gas saturation of the section.
3) Data correlation, mapping and integration into available G&G data.
Identified hydrogen+helium anomalies mapped and integrated into available G&G data, priority locations for hydrogen drilling are recommended. Areal objects associated with geological structures (traps) with good reservoir properties and an effective seal will be preferable.

COMBINED METHOD OF SUBSOIL HYDROGEN AND HELIUM MEASUREMENTS SHALL BE WIDELY USED DURING HYDROGEN EXPLORATION CAMPAIGNS FOR EVALUATION OF HYDROGEN POTENTIAL AREAS AND DRILLING DE-RISKING
