Tarim Basin newly discovered the fault-karst carbonate reservoirs, which are formed by large-scale tectonic fault activities and multiple-stage karstification. Four kinds of mediums coexist in including large cave, vug, fracture matrix. The fractures interconnect with caves series to form vertical beads-on-string structure, is most common connection pattern reservoirs. To provide a well test me...

Many of the large number underground works constructed or under construction in recent years are unfavorable terrains facing unusual situations and conditions. This is case subject study this paper: a tunnel excavated evaporitic rocks that experienced significant karstification problems very quickly over time. As result situation, causes may underlie rapid investigated novel methodology present...

Abstract In the Northern Calcareous Alps (NCA) there are countless small lakes with orographic catchments that often located only slightly below respective summit regions. On one hand, in karstable aquifers and their existence is likely to be related karstification. Then, they expected directly connected karst water body. These classified as lakes. other alpine environment also influenced by gl...

Hypogene speleogenesis involves the formation of solution-enlarged permeability structures driven by ascending water acquiring its acidity from deep-seated sources. This process occurs in a wide range geological settings and different lithologies. Although hypogene has received increasing attention last two decades, identification former activity caves remains challenging, unless unambiguous mo...

Detecting karstification processes in hydrocarbon carbonate reservoirs is important because of their porosity, permeability and also the risk associated with their drilling. A very useful technique to locate buried karsts is 3D seismic. In this research, seismic frequency decomposition (spectral decomposition) and seismic inversion techniques used to identify these sub-surface diagenetic featur...

Salinization of groundwater in semiarid regions, as a limiting factor of use, has a strategic importance. In this study, the sources of salinity, chemistry and Quality of groundwater in Robat – Khorramabad plain have been identified using geochemical methods. Using data analysis, the concentration of cations and anions are recognized as Ca2+>Na+ >Mg2+>K+ and HCO3-> Cl-> SO42+> NO3-> F-. High co...

Hypogenic caves, linked to carbonate rock dissolution due CO2- and H2S-rich ascending deep waters, represent more than 10% of karstic networks worldwide; a proportion that increases as these systems are better constrained. However, interaction between hypogenic epigenic processes is still poorly understood, especially since the subsequent invasion surface water often obliterates morphological m...
