Interests: The main research fields of Prof. Tivadar M. Tóth cover a wide spectrum within the theme of evaluating fractured hard rock reservoirs. He deals with the reconstruction of petrological, structural, and paleohydrological evolution of different igneous, metamorphic, and carbonate rock bodies as well as simulation of their fracture networks at the reservoir scale. Concerning methodological problems, he concentrates on the potential of using measurable geometric parameters for simulating fracture networks. He has organized numerous research projects on complex evaluation of fractured hydrocarbon and geothermal reservoirs as well as radioactive waste depositories.

Special Issue Information

Dear Colleagues,

Naturally fractured fluid reservoirs are of key importance in numerous fields of applied geology. At present, the largest part of the known hydrocarbon reserves is stored in these systems. Advanced geothermal energy utilization requires fundamental understanding of fractured rock bodies. In addition, safe deposition of hazardous wastes, mining of critical elements through the in situ leaching technique, among many others, use such rock bodies. Nevertheless, to adequately reveal the behavior of fractured reservoirs, petrological, structural geological, geomechanical, hydrodynamic, geophysical, etc., datasets should be evaluated simultaneously.

In this Special Issue, manuscripts involving such a complex approach are invited, whether concerned with case studies or methodological aspects.

The identification of small scale faults (SSFs) and fractures provides an improved understanding of geologic structural features and can be exploited for future drilling prospects. Conventional SSF and fracture characterization are challenging and time-consuming. Thus, the current study was conducted with the following aims: (a) to provide an effective way of utilizing the seismic data in the absence of image logs and cores for characterizing SSFs and fractures; (b) to present an unconventional way of data conditioning using geostatistical and structural filtering; (c) to provide an advanced workflow through multi-attributes, neural networks, and ant-colony optimization (ACO) for the recognition of fracture networks; and (d) to identify the fault and fracture orientation parameters within the study area. Initially, a steering cube was generated, and a dip-steered median filter (DSMF), a dip-steered diffusion filter (DSDF), and a fault enhancement filter (FEF) were applied to sharpen the discontinuities. Multiple structural attributes were applied and shortlisted, including dip and curvature attributes, filtered and unfiltered similarity attributes, thinned fault likelihood (TFL), fracture density, and fracture proximity. These shortlisted attributes were computed through unsupervised vector quantization (UVQ) neural networks. The results of the UVQ revealed the orientations, locations, and extensions of fractures in the study area. The ACO proved helpful in identifying the fracture parameters such as fracture length, dip angle, azimuth, and surface area. The adopted workflow also revealed a small scale fault which had an NNW–SSE orientation with minor heave and throw. The implemented workflow of structural interpretation is helpful for the field development of the study area and can be applied worldwide in carbonate, sand, coal, and shale gas fields. Full article
