He-Technology is a field geochemical method and measures Helium-gas concentrations in various natural media.
The analysis of Helium spatial concentration variations for mineral resources, helium and petroleum exploration have been attempted since the early 1970s.
However, Sealium is a founder of Offshore He-Technology and was the only one to obtain reliable results confirmed by drilling.
Inert noble gas
Elements in the universe
Helium presence on the earth
Helium (from Greek translit. Helios, lit. ‘Sun’) is a chemical element with atomic number 2.
The second lightest and second most abundant element in the universe after hydrogen.
Chemically inert, does not form any chemical compounds.
Helium ACCUMULATES in hydrocarbons and HARDLY dissolves in the water
Helium has a HIGH migration ability
Helium has a MAXIMUM vertical migration path through sedimentary cover to the surface
Helium anomalies on the surface provide SIGNIFICANT information about geology and HC presence
Helium constantly migrates vertically from crystalline basement through micropores and microfractures of sedimentary cover forming Helium microseepage at the earth surface.
While migrating to the earth surface Helium can be temporary captured and accumulated in Helium tarps – specific geological structures of enhanced Helium capacity.
Oil and gas pools are efficient Helium traps due to significantly higher He solubility in hydrocarbons compared to formation water and surrounding dry fractures.
After reaching saturation limit traps start releasing high Helium concentrations which migrate to the surface using the same advection mechanism.
HELIUM DETECTION ON THE SURFACE
He-Technology developed by Sealium allows to detect Helium concentrations in the waterbody and is based on the following principles:
Helium concentrations measured in-situ, without transport of probes
Grid step selection takes into account targeted geological objects
In-field measurement systems are fully automated
Superior precision of measurements
Data interpretation and processing based on mathematical and physical algorithms
Offshore He-Technology is based on the measurement of Helium concentration in the seawater column.
HELIUM DATA INTEGRATION EXPERIENCE IN EXPLORATION
The results of a longstanding research and in-field surveys indicate that Helium Technology can be used by itself. Notwithstanding, to effectively determine the depth of hydrocarbon deposits obtained Helium data is often used in conjunction with other known methods.
Helium data is well integrated with the seismic information and helps at the stage of Seismic data interpretation and for drilling locations planning.
Heologic has as well obtained excellent drilling results by integrating Helium data into a satellite imaging based on the continuous remote sensing of the Earth.
By integrating MT-sounding and Helium data Heologic effectively identifies the location and the depth of structures bearing hydrocarbons.
Regardless of the different integration methodologies, drilling is the one and only method to confirm the results of our He-Technology. Based on more than 20 years of experience in He-Technology, we declare that within intensive positive Helium anomalies the probability of success (obtaining an industrial inflow of hydrocarbons) is much higher and reaches 90% or even more.
