Intertek offers a complete suite of core and geochemical analyses on shale cores designed to provide reservoir engineering, petrophysical, and production data needed in gas shale reservoirs.
The challenges facing the development of shale gas reservoirs require knowledge and expertise in the field and in the laboratory to ensure that timely and accurate data is available to optimize production and minimize risk. Complex reservoirs demand advanced techniques to ensure that the comprehensive characterization of rocks and fluids is available.
To support gas shale reservoir characterization requirements, Intertek provides a comprehensive suite of Total Quality Assurance services and analyses in the field.
These services include:
Laboratory Shale Core Handling
Handling of cores in the laboratory is no less important than in the field. Shale cores are sensitive to dehydration, which can alter the data quality required for important characterization measurements. It is important to limit exposure to the environment when dealing with most shale cores.
Proper sampling of cores for detailed analysis is critical to getting optimum data. Our sampling protocols include:
Intertek has recently upgraded its image analysis software to the new Avizo™ software package. This advanced software package provides state-of-the-art imaging capability.
Enhanced Absorption Isotherm Measurements for Shale
Because of the relatively low organic content, shale samples typically give low precision for adsorption isotherm measurements. Intertek uses larger samples and enhanced techniques to provide high precision isotherms for shales.
Shale Core Analysis — Ultra-low Permeability Reservoirs
Shale cores provide a challenge to the industry because of their unique properties. Traditional routine or special core analysis measurement techniques do not perform well on ultra-low permeability shale reservoirs. Therefore, new "unconventional" methods are employed. Intertek employs a comprehensive suite of analyses and services to properly characterize difficult shale reservoirs. A typical suite of basic petrophyscial measurements for shale reservoirs might include:
As Received Measurements:
Intertek also provides additional measurements that can be important to the production of gas from shale reservoirs including:
