Abstract
The paper describes the approaches to the interpretation of natural fracturing based on the core and special logging materials. Multi-scale core studies of fracturing allow to describe micro-fracturing and small macro-fractures, as well as to classify the types of large macrofractures, to study the features of the void space, assess the influence of diagenetic processes, and quite reliably classify the fractures according to their genetic characteristics, or to classify them as human-induced. Integration of core and logging data allowed to define orientation of fractures interpreted from the core, to identify the fractures overlooked during the initial interpretation of microimagers data, to exclude false and induced fractures, as well as to go beyond the tools’ resolution and estimate intense small-scale fracturing.
Materials and methods
Materials: the results of a core-based multi-scale study of fractures and special logging methods (microimagers, full-wave sonic log). Methods: integration, macro-description of core materials, classification of fractures by genetic characteristics, interpretation of fractures by well logging data.
