Heliometric data is the shortest path to high-grade your onshore or offshore O&G acreage
OIL & GAS
Actual Geology has developed a game changing Helium gas-based technology that is revolutionising the oil and gas industry that significantly reduces risk in hydrocarbon onshore and offshore exploration.
We are the only company in the world that understands the specific relationship of Heliometric data with hydrocarbons and has deep understanding of the data integration into other geological and geophysical information needed for a complete state-of-the-art de-risking process for O&G exploration. We have in-house capabilities for best-in-class processing and interpretation of satellite, MT-sounding and seismic imaging to confirm the presence of hydrocarbons, zones with a higher permeability and faults.
We are working with clients with our innovative holistic approach and through this so called “accelerated exploration de-risking approach” Actual Geology can help clients to take exploration blocks, de-risk them in around 18 months and proceed with discovery and appraisal wells all in approximately 26 months, much shorter than any project using traditional approach.
Actual Geology has completed more than 200 projects to date. We know that drilling within the Heliometric anomalies gives more than an 80% chance of success in obtaining hydrocarbons in commercial quantities. On the contrary, the probability of success drilling completely outside an anomaly is close to nil.
This methodology has been used in different types of deposits, conventional, unconventional, onshore, offshore, with different types of oil or gas and in the most diverse regions (sea, transition zones, plains, plateaus, mountains, rivers, jungles, deserts, etc.).
Onshore Prospecting and Frontier Exploration
-
Onshore Prospecting and Frontier Exploration of oil and gas fields is one of the main activities of our company.
-
In order to detect promising zones and plan 2D or 3D seismic operations, Heliometric field work is carried out before seismic data acquisition. In some cases, Heliometric surveys are carried out in areas selected by earth remote sensing, gravity or magnetic surveys.
-
To improve the quality of seismic data, Heliometric surveys are carried out along seismic profiles during or after seismic surveys. Such Data Integration is performed by our sister company www.nordicgeophysical.com.
-
To assess the oil and gas prospects, Heliometric survey is carried out over selected prospects prior to drilling. Based on such work, the prospects are ranked and the most risk-free well locations are identified.
-
After the first discovery well, the Heliometric Image for selected geological conditions over the next prospects will be generated and well locations selected.
Offshore Prospecting and Frontier Exploration
-
Actual Geology is specialising in Offshore Heliometric Surveys and owns know-hows in data acquisition and processing.
-
We have developed unique solutions to run uninterrupted Heliometric measurements regardless of water depth.
-
Regional 2D Offshore Heliometric survey is carried out at the stage of prospecting by profiling potential areas before 2D/3D seismic surveys. Such regional profiles determine very clearly the areas of interest in a short time.
-
Areal 3D Heliometric survey with a small measurement step is carried out above identified structures and traps to determine the most optimal location of exploration wells.
-
After the first discovery well, the Heliometric Image for selected geological conditions over the next prospects will be generated and well locations selected.
Onshore / Offshore Near-Field Exploration
-
We perform Near-Field (NF) surveys for onshore and offshore areas.
-
There is one indisputable advantage of Heliometric surveying in NF field - the ability to correlate with anomalous background levels of Heliometric data over existing fields and search for a similarity within the studied NF areas.
-
To improve the quality of seismic data over NF areas, Areal 3D Heliometric survey is carried out to help to identify the most promising hydrocarbon saturated objects.
-
In the high anomalous zones detected by Areal 3D Heliometric Survey the additional close-up survey with a smaller step between points/stations will be carried out straight after the main part of survey. This approach allows to identify the best well drilling locations over zones with a high hydrocarbon potential.
-
Collect a sufficient amount of Heliometric data from the studied area
-
Identify Heliometric Anomalies
-
Integrate Heliometric Anomalies into available G&G data and well drilling results (if available)
-
Identify and rank prospects, cut off high-risk zones
-
Drill the discovery first well in the most promising zone
-
Correlate drilling results with Heliometric data
-
Generate Heliometric Image of commercial well for the entire acreage
-
Plan a well placement pattern for the studied area according to Heliometric Image
Helium Gas Mud Logging while drilling
-
Our specialization in Heliometric measurements has allowed us to create an automated system for Helium Gas mud logging.
-
Our highly sensitive Heliometric system is used as an addition to the standard method of mud logging.
-
The data we receive while drilling provides reliable information about the approach to and passage of productive formations.
-
In the case of drilling only on Heliometric data (which happens in the absence of high-quality geophysical information and several unproven targeted layers), Helium gas mud logging while drilling allows to monitor the Heliometric background level and determine the penetration to the targeted petroleum reservoir that provides the highest Helium flux flow.
Onshore/Offshore Early Field Development
-
Field drilling in identified Heliometric anomalies can be more accurate using a state-of-the-art machine learning solution provided by our sister company Froswell (www.froswell.com).
-
After drilling the first 3-5 wells within the structure or trap, the production data for each well will be processed along with the Heliometric data in such a way that subsequent drilling is the least risky.
-
For such purposes, we generate virtual wells and pre-calculate their productivity and forecast their work for years to come. When drilling wells with our solution, the risk of failed wells within the field is greatly reduced.
-
This approach allows you to drill wells only in the best places, not tied to a standard well location grid, and also achieve the planned oil recovery factor while drilling fewer wells.
Mature Fields and Secondary Recovery
-
Heliometric data is of great interest in terms of planning and drilling new wells in mature onshore or offshore fields.
-
Heliometric monitoring of the well is considered to be one of the fastest surveys for determining the potential of wells within the field. As part of such work, we cyclically measure Helium gas in the annulus at wellheads and, based on certain algorithms, rank high-potential wells, as well as make recommendations for wells that do not make sense to invest in due to their lack of production potential.
-
We also conduct Areal 3D Heliometric surveys to identify anomalies within the production field. Such surveys allow to collect accurate data on the location of residual reserves and sweet spots to make a plan for new drills and the implementation of second recovery operations.
-
Deep integration of Heliometric data into the field's hydrodynamic model using machine learning solution makes it possible to obtain an up-to-date model of a new level, predict exact production, water cut, and bottom hole pressure for years ahead. Our MAPE (Mean Average Per Cent of Error) is the smallest in the industry due to Heliometric data. This solution provided by our sister company Froswell (www.froswell.com)
Abandoned wells
-
Conducting Areal 3D Helium surveys in the area of stopped and abandoned wells and fields makes it possible to determine hydrocarbon potential and, in case of large Heliometric anomalies around the wells, to plan the return of wells into production.
-
We pay special attention to work around abandoned offshore platforms. Offshore Helium surveying provides E&P operators with sufficient information to make decisions about decommissioning of platforms or taking them back into the production.
-
This service is rapidly gaining market share and we see huge potential in this kind of valuation of abandoned wells and fields.

Correctly interpreted Heliometric data over a mature field shows:
-
positive Heliometric anomalies as projections of undrained parts of the reservoir with active residual hydrocarbon reserves, sweet-spots and bypassed zones;
-
negative Heliometric anomalies as the drained parts of the reservoir, low-pressure zones (including pressure cones) or flushed zones.
