Abstract
The analysis of images of the whole core (rock sample extracted from a well) is in demand in modern geophysics. The subject area determines the manner of core image processing and the form of presentation of the results. A common form of representing well data is measured values ordered by depth. Core samples are also ordered by depth, and core sample images are a collection of individual photographs or tomographic scans often with missing data at some depths. A typical image of a core sample contains a meter-long sample of rock. At the same time, in practice, it is often required to evaluate the characteristics of centimeter intervals. This paper proposes an approach to creating an ensemble of textural features of core images, presented in the form of depth-ordered profiles, which allows the results to be used in conjunction with other geological and geophysical data.
