Heliometric Data supports decision-making in decommissioning onshore wells and offshore platforms
ABANDONED O&G WELLS AND FIELDS
Thousands of abandoned oil and gas production wells are scattered across the globe, causing methane, benzene, hydrogen sulfide, or volatile organic compounds (VOCs) emissions and other environmental hazards. The global impact is hard to measure.
Operators are faced with a large volume of wells to be assessed for their oil & gas or other resource production potential before plug & abandonment.
Less profitable assets or abandoned wells may be idled for economic purposes and then later brought back into production, some could be turned even towards heat/cooling production.
The use of Heliometric data in assessment of well production potential is growing constantly during last years. Before decommissioning an oil and gas well 3D Areal Helium survey is conducted with a construction of Heliometric anomalous zone map around studied wells.
In case wells can not be used for O&G production from existing layers but still anomalous helium concentrations can be detected at well site, operators can consider other production layers or even using wells for Geothermal resource generating energy for homes and businesses.
We support our customers in a plug & abandonment and further production investment decision making by integration of obtained Heliometric data, oil/gas historical production data and geology into ML-based models taking into account the minimum number of wells for successful project implementation.

Wells of Opportunity
Abandoned wells with a remaining production potential show positive Heliometric anomalies that are considered as projections of undrained parts of the reservoir with active residual hydrocarbon reserves, sweet-spots and bypassed zones;
Abandoned wells without any production potential will be surrounded by negative Heliometric anomalies that are considered as the drained parts of the reservoir, low-pressure zones or flushed zones.
