Unravelling the burial-deformation history of sedimentary rocks is prerequisite information to understand regional tectonic, sedimentary, thermal, and fluid-flow evolution foreland basins. We use a combination microstructural analysis, stylolites paleopiezometry, paleofluid geochemistry reconstruct Meso-Cenozoic carbonate sequence Cingoli Anticline (Northern Apennines, central Italy). Four majo...

Abstract Using observations and descriptions of drilling cores, image logging, microscopic section, argon ion polishing field emission scanning electron microscopy, X-ray diffraction, whole-rock trace element analysis, the study shale reservoir diagenesis space types in Fengcheng Formation Mahu Sag was conducted. Considering contents their ratios (Sr/Ba, V/Ni, Th/U, V/(V + Ni), U/Mo, Sr/Cu), is...

Mechanical twins are common microstructures in deformed calcite. Calcite have been used for a long time as indicators of stress/strain orientations and magnitudes. Developments during the last decade point toward significant improvements existing techniques well new applications calcite twin analysis tectonic studies. This review summarises recent progress understanding formation, including nuc...

primary sedimentary and secondary structural and diagenetic processes are responsible for heterogeneity in carbonate reservoirs and recognition of these factors is very essential subject in modeling these reservoirs. image logs are very useful for identification of structures and small scale sedimentary features. in this research, using image analysis of formation microimager log (fmi) in a dri...

Abstract Availability of gases at the field level makes attractive to water-alternating-gas (WAG) process for low viscosity and light oils carbonate reservoir. However, impact reservoir heterogeneity on WAG performance is crucial before application. In general, ramp carbonates have due variation permeability porosity. significantly affected by variations. This article investigates merits demeri...

The paleostress history and associated deformation mechanisms affecting passive margins are seldom studied, as access to offshore parts is rather limited. We analyze an wellbore core of the Albian, post-rift carbonates Sendji Fm which directly overlies salt Aptian Loeme in Lower Congo Basin. Paleopiezometry based on stylolite roughness inversion (SRIT) calcite twin (CSIT) was combined with frac...

The Lower Cretaceous reservoir core samples from the upper part of Qamchuqa Formation, Baba Dome, Kirkuk Oil Company, show evidence for multistage episodes dolomitization and a complex diagenetic history. Optical microscope reveals muti-phase diagenesis: an early stage diagenesis its alteration, later, by evaporated seawater under near-surface setting conditions, followed different event dolomi...
