Carbon storage is one of the leading technologies for industry decarbonization. Excellence Logging surface data logging services play a key role in wells drilled for carbon dioxide storage in deep aquifers or depleted hydrocarbon reservoirs. While drilling, the geochemical analysis of cuttings (GEAR) and dissolved gases arriving at the surface (SAFE) provide an early assessment of potential storage complex capacity. This information includes seal rock integrity, reservoir quality and reservoir characterization. This information is crucial for compliance with the environmental regulations for carbon dioxide injection and storage projects. Drilling the lateral or horizontal sections for these wells also present hole-cleaning challenges and the monitoring of hole cleaning efficiency in real time enables safe and efficient drilling with minimum non-productive time (HCM).
Geothermal energy is already well-known as a clean, renewable new energy source that is easily available. The construction of geothermal wells, however, poses unique drilling and formation evaluation challenges with the elevated temperatures in these wells limiting the use of standard downhole tools and their measurements. Excellence Logging surface data technology addresses many of the challenges with cost-effective, non-intrusive geological and geochemical solutions. The Real-Time Fluid Logging Service (SAFE), for example, is tailored to the geothermal environment to detect the helium, hydrogen, hydrogen sulphide, light hydrocarbon and carbon dioxide that may be present as dissolved contaminants. Assessment of mineral content, mineral alteration, and elemental composition of formation cuttings (GEAR) provides a better understanding of the geothermal setting and also provides the mechanism to monitor radioactive elements in the rocks for regulatory compliance. Integration of this information with fracture identification (EKLD) provides a fuller picture of the subsurface environment. Last but not least, the monitoring of hole cleaning efficiency in real time allows timely actions to be taken for safe and efficient drilling with minimum non-productive time (HCM).
Finding and producing natural hydrogen and helium from natural accumulations is fast becoming a reality. The two gases are often found together in substantial concentrations. For such projects, Excellence Logging provides specifically configured, high-resolution gas equipment to detect and quantify light and highly diffusive helium and hydrogen gases in real time while drilling. Hydrogen and helium gases are occasionally associated with hydrocarbon gases like methane (SAFE). EXLOG’s fast gas chromatographic analysis of these gases ensures that no zone of interest is missed and that the presence of methane is clearly identified. Safe and efficient drilling of natural hydrogen wells is also ensured by Excellence Logging real-time monitoring of hole cleaning efficiency for minimum non-productive time (HCM).
Across all aspects of Excellence Logging new energy technology applications, the data recorded at the rig site are easily accessed globally via the SkyView web-based, real-time data transmission service. This approach reduces carbon footprint and encourages faster decision-making for greater efficiency. At the same time, shared access to data enables supports wider collaboration between operational activities and Excellence Logging Data and Consultancy Services that include Well Site Geology (WSG) and GeoPressure Geomechanics (GPGM)
