Hyperspectral imaging of core reveals the impact of (clay) minerals on flow properties through reservoir rocks: A unique source of information for the geothermal-, petroleum-, and CCUS industries.
Deep Atlas’ approach to mineral identification is unique in the industry in that it disects the mineral infrared absorption fingerprint in a structured and repeatable way. The permeability prediction is continuous along the entire length of the core, one of the first companies in the world to offer this! It is Deep Atlas’ mission to make mineral imaging and permeability prediction a standard analysis in subsurface developments.
Hyperspectral imaging is used to obtain a direct measurement of (clay) mineral properties (i.e. XRF is an indirect method of defining mineralogy). The imaging workflow has been developed in partnership with the University of Twente (NL). Machine learning from plug data is used to predict a continuous permeability profile. The AI part of the workflow is developed with the help of the University of Groningen (NL).
A unique, repeatable and robust solution to obtain a continuous mineralogy profile and permeability prediction providing better understanding of reservoir flow properties.
Easy application in subsurface modelling of digitized mineralogy and flow information extracted from fresh- or legacy core.
Reduced uncertainty in reservoir characterisation and geochemical-, and geomechanical analysis.
Enhanced reservoir and flow properties description leading to improved quality of investment decisions.
Rock samples used for mineral imaging are focused on using cores and plugs, but dry drill cuttings also may be considered. An enormous amount of cores and plugs are already available worldwide, however a lot of the potential value is not used. Deep Atlas’ offering creates a huge opportunity for players in the field to maximize the value of information from existing rock samples.
Deep Atlas has their own hyperspectral camera and acquisition setup in the office lab in Groningen. Data acquisition from core and plugs can be performed either at the Deep Atlas facility or at the customer if required.
