Summary:
Laboratory core investigations provide the necessary data for geological modeling, hydrocarbon field evaluation and development. The validity of the core sampling in case of high heterogeneity formations is no less important for subsequent laboratory studies than the level of such investigations, especially in the case of source rocks. Implementation of express (directly in core storage) continuous high-resolution thermophysical profiling of full-sized or slabbed cores allows to register detailed variations of basic rocks physical properties and can be used for optimization of the representative core sample collection creation. It becomes particularly topical under the conditions of the limited amount of core samples, financial and timing constraints for core investigations in the absence of a widely accepted regulatory document for core sampling for subsequent laboratory investigations. Core sampling approach based on thermophysical profiling is described with an example of its application on full-sized core samples from an oilfield well (target intervals are the Bazhenov and the Abalak formations).
