Constantly experiencing different types of terrain, weather and geology
HELIOMETRIC DATA ACQUISITION
Our data collection principle is very simple. The quality of the data must be of the highest level and we have no room for error.
Therefore, land and sea data is collected by our automated field systems, which are controlled by experienced personnel. There is no way for operators to change the data values or have severe mistake that could lead to false information.
On land, we use a method that allows us to quickly determine the gas flow and helium content. All information is immediately checked for quality and in the presence of any error, the operator receives a command to repeat the measurements.
At sea, our systems are also fully automated and allow us to measure the concentration of helium in the water in the shortest possible time right on the ship.
A clear process for checking the quality of the sample and the heliometric data itself at sea does not require stopping the vessel and re-shooting the measuring station.
We use only our own personnel with maritime experience and maintenance of our systems.
NOTICE: We do not let any other partner companies access data or control the data collection process, guaranteeing the confidentiality of our customers.
Survey Types
The collection of Heliometric field data is based on the principle of sampling at predetermined measurement points on land and offshore sampling stations.
Works are carried out either along the profile (2D Profiled Survey), or along the area (3D Areal Surveys), or combined.
The type of research work is determined on the basis of geological tasks, scope of work, location and budget of the customer.
2D Profiled Heliometric Surveys
This type of survey is used for large areas prior to seismic data acquisition to identify areas of interest or during/after seismic acquisition along a seismic profile to improve the quality of seismic interpretation.
-
Evaluation of under-analyzed basins
-
Elimination of low prospectivity and high-risk zones
-
Identification of potential structures with hydrcarbon, geothermal, natural helium and hydrogen saturation
-
Allocation of areas with improved fractured permeability and active fault zones
-
Possible within areas where Seismic data acquisition can’t be conducted
3D Areal Heliometric Surveys
This type of survey is used for acreages with prospects identified by 2D Profiled Helium Surveys or other methods to confirm resource saturation within the prospect, rank prospects and de-risk drilling operations.
-
Elimination of low prospectivity and high-risk zones
-
Precise definition of resource saturation in perspective reservoir
-
Identification and ranking of prospective drilling targets
-
Determination of areas with improved fractured permeability
-
Forecasting of reservoir properties, distribution, delineation
-
Recommendations for exploratory and appraisal wells, drilling de-risking
-
Identification of sweet spots and residual reserves at the oil and gas producing fields
ONSHORE DATA ACQUISITION
- In-situ measurement of a continuous Helium flux not a single gas sample
- Operators do not interfere into data collection process - no human factor
- Repeated measurements at every point/station
- Continuous monitoring of temporal Helium fluctuations during the survey
- Large amount of statistical data collected under non-stop quality control
2D Profiled Survey for Exploration
-
Step between points: 250m or 300m or 400m
-
Distance between profiles: from 800m to 1200m
3D Areal Survey for Petroleum, Gas, Helium and Hydrogen Exploration
-
Step between points: 100m (100 points/km2) or 150m (44 points/km2)
3D Areal Survey for Geothermal Exploration
-
Step between points: 50m (400 points/km2) or 100m (100 points/km2)
3D Areal Survey for Oil and Gas Producing Fields
-
Step between points: 50m (400 points/km2) or 100m (100 points/km2)
-
Heliometric data is recorded in automatic mode with a chosen step between measurement points in a specially prepared borehole up to 1m deep
-
Measurement is carried out by sealed measurement systems in-situ by pumping the Helium flux directly to Heologic automatic device with a Helium gas sensitivity of 0.01 ppm
-
A portable Heologic automatic Helium measurement system is approx. 25 kg in weight and adapted to rough field conditions, equipped with advanced self-developed software, high-precision satellite navigation, control units, sample quality analysis system and operator controls
-
Heologic automatic data acquisition system is connected to the borehole and measures continuous Helium flux for 5-10 minutes at the point
-
The measurement system is pulled out of the borehole upon measurement completion
-
We have experience and equipment for field sampling and measuring C1-C5 and radon gases.
-
In many cases additional subsoil gases are taken after express-analysis of heliometric data in the most promising locations. This approach saves time and budget and brings a wealth of valuable information to the Exploration teams. Geochemistry work is planned in advance, as we may collect subsoil gases during Helium survey or upon completion of the field work.
Open Terrain
The main advantage of working in open terrain is the speed of movement around the work site. Before starting surveys, we plan the work in detail, load the exact coordinates of points into navigation systems, and carry out reconnaissance on the ground. As with all types of surveys, project logistics must take into account the availability of villages, roads, and emergency evacuation opportunities. Depending on the type of soil, our speed of work can reach up to 50 points/day/team.
Forest
Working in forests and jungles is a more complex process. Since there are sometimes no roads and it is difficult to traverse the dense vegetation, our team may prepare the trails in advance. This primarily applies to the tropical jungle. Despite the preparation of rare trails, our work does not have any impact on wildlife. An important point is the presence of predators, so the escort and protection of the operator plays an important role in this type of field work.
Desert
Field work in the desert requires a strong team experience and special equipment, protected from sunlight, sand and possible mechanical damage. Our teams use special systems and know-how to extract near-surface Helium gas from the sand. We often build mobile desert field camps manned by separate logistic teams to provide water, food and fuel. The speed of work is limited to 50 points/day/team and subject to the season, weather conditions and the height of the dunes.

Hills
Rough terrain or hilly conditions require some planning in advance. We are often faced with situations where it is practically impossible for the operator to reach the measurement point. In such cases, the measurement points will be taken from the smallest possible distance. In the presence of rocky soils, our special gas sampling system will be applied. The speed of field work can vary from 15 to 35 sampling points per day with one team.
Mountains
Surveys in the mountains are the most responsible and difficult task among all possible field work on land. Our main focus is on HSE and the quality of the data obtained. Due to the certain difficulty of obtaining the correct Heliometric values in the mountains, we use our own gas measurement unique developments and constantly monitor the quality of the data. The speed of work varies depending on the season, weather conditions, and road availability from 5 to 15 points per day by one team.
Winter Onshore Surveys
Field work in winter is quite common for our business due to the fact that access to hard-to-reach areas of work is opened. This type of work has some weather limitations. Movement on the site takes place on snowmobiles. Data collection is complicated by frozen soil, which requires experience and the use of various special tools for correct gas measurements. The speed of work can vary from 10 to 35 points per day by one team
OFFSHORE DATA ACQUISITION
- In-situ measurement of a Helium gas sample from the water
- Operators do not interfere into data collection process - no human factor
- Repeated measurements at every point/station
- Continuous monitoring of temporal Helium fluctuations during the survey
- Large amount of statistical data collected under non-stop quality control
2D Profiled Survey for Offshore Exploration

3D Areal Survey for Offshore Oil and Gas Production/Abandoned Fields
-
Step between points: 100m (100 points/km2) or 150m (44 points/km2)
-
Research Heliometric work on the water is carried out from a floating vessel by predetermined coordinates of measurement stations
-
When working on rivers, lakes and swamps, portable complexes are used to measure helium gas in the bottom water
-
In offshore projects, seabed water samples are delivered to the onboard laboratory either through a flexible hose or a sampler, depending on the water depth
-
Measurement of Helium concentration is carried out by sealed measurement systems in automatic mode that fully controls the entire process using specialized Heologic software
-
Analysis of water samples is carried out within a few minutes after sampling
-
The number of rejected samples is extremely minimal, which eliminates the need for repeated attempts to measure
-
When working on water bodies, customers are often interested in sampling other gases. We have experience in offshore sampling and measuring C1-C5 gases.
-
We can either only take water samplers for further measurement of gas concentrations in the onshore laboratory, or install special equipment on board the vessel to measure the gas immediately after sampling.
-
Such work is planned in advance, as it slows down the work on collecting heliometric data. It is possible that additional gases will not be measured at all stations or measured upon completion of the heliometric survey.
River, Lake, Swamp
Having extensive experience in sampling helium gas in water bodies, we have created our own mobile automatic system for determination of gas concentrations in swamps, rivers and lakes. This system with flexible hose for water suction is installed on boats or all-terrain trucks . The measurement time is about 10 min/station. Under favorable weather conditions and the absence of strong currents, our operators perform more than 30 stations per day.
Transit Zones
Working in transition zones presents a challenge for many geophysical and geochemical technologies. Our developments have allowed us not only to achieve high data quality, but also to keep our work fast at shallow depths starting from a depth of 1 m. Through a flexible hose system, bottom water is taken and analyzed at our mobile automatic system. The speed of work depends on the tide, season and wave height, on average, one team performs 40-70 stations per day.
Winter Surveys on the Ice
In the Northern Hemisphere we often perform Heliometric surveys on rivers, lakes, swamps and in transit zones on ice during the winter season. We use a unique method of sampling on ice, which allows us to be confident in the correctness of the Heliometric data, and also maintain the speed of work in the region of 30-40 points per day by one team. Movement on the site only happens on snowmobiles and in compliance with the strict HSE procedures.
Shallow waters
When working in water depths up to 200 meters, we move around the site either on a supply or on a research vessel. A full-fledged laboratory with automatic lines for degassing and measuring Helium gas is installed on board. We work closely with the pilots of the vessel to sustain the speed and quality of work. We obtain a high quality and reliable data within just a few minutes after sampling. The speed of our work at sea is about 80 points per day under favorable weather conditions.
Deep waters
Working at depth is a completely different approach, which requires the experience and smooth operation of all automatic measuring systems that take on a huge amount of work. Water sampling is carried out below the level of the current. There are several measurement lines installed on board, all procedures are sharpened and do not allow a single mistake. The ship never returns to the station for a re-measurement. The speed of work is about 100-120 stations per day.
