Special core analysis to study oil and gas reservoir anisotropy

Relevance of the work is caused by the need to maximize production of reserves from existing fields with increasing depletion by selecting the most appropriate development strategy. Objective: To consider the study issues of the spatial anisotropy of reservoir petrophysical properties by the laboratory methods. Methods: The samples were subjected to thermal demagnetization, and then the residual magnetization was measured to determine the direction of core spatial orientation. Spatial measurements of acoustic and magnetic properties were carried out by the oriented samples. Additional research on the photographic scanning reflects visual distribution of changes in sedimentary properties and environments. Results: The obtained results show the significant correlation of magnetic and acoustic properties and permeability of the core samples and allow predicting the direction of improved filtering. The author found out the relationship between rock structure characteristics and permeability and porosity of reservoir rocks.
