A Comparative Study of Silicified Rock Reservoir in Shunnan 4 well of Tarim Basin with Hydrothermal Chert Reservoir of Parkland Gas Field in Western Canada Sedimentary Basin
… the silicification are identified including replacement quartz, quartz cement (characterized by 4 textures: equant quartz, bladed quartz, overgrowth and quartz cement in later fractures) and three types of calcite cement (CC1-CC3). Geochemical analysis including Si-O isotope analysis on quartz and …

Ultrahigh-resolution paragenesis of the Cambrian-age Mt. Simon Sandstone at a burial depth of 1.8-2.1 km, Illinois basin, USA
… paragenesis of Cambrian-age Mt. Simon Sandstone quartz arenites buried at 1.8-2.1 km within the Illinois Basin. Results have yielded valuable new insight into the evolution of this important subsurface reservoir and provided the depositional and diagenetic history required to enhance carbon …

Depositional and Diagenetic History of the Permian Unayzah A Reservoir, South Haradh, Saudi Arabia with Implications for Deep Gas Exploration and Development
… and mesogenetic reactions. Early or eogenetic cements are dominated by clay rims that formed at temperatures below 70oC. Oil migration along stylolites probably from Silurian source rocks occurred during the early mesogenetic stage followed by barite, quartz and carbonate cementation. Oil …

Subsurface dolomitization and porosity occlusion within Early to Middle Ordovician strata of the Illinois Basin, USA
… Specifically, porosity occlusion by dolomitic cementation is pronounced in the Shakopee and Everton on the northern shelf of the basin, and, increases progressively to the south into the deeper part of the basin. Three sample locations were selected for this study based on relative …

Fracture Growth Kinematics in Tight Sandstone Reservoirs
… the crack-seal opening history for multiple cement bridges sampled at different distances from the tip of three opening-mode fractures in Travis Peak Sandstone of the SFOT-1 well, East Texas. Crack-seal cement bridges have been interpreted to form by repeated incremental fracture opening and …

A Study of Compaction and Cementation of Sandstones in the Athabasca Basin, Northern Saskatchewan, Canada, and Implications for Uniformity-related Uranium Mineralization
… between the metamorphosed basement and the quartzose sedimentary rocks. Previous studies have generally agreed upon a diagenetic-hydrothermal model in which the URU mineralization occurred at elevated temperature (>200℃) and deep-burial (5-7 km) conditions under normal geothermal conditions. …

Relative timing of dolomitization and silica cementation in the Cambrian Potosi and Eminence Dolomites in the Illinois Basin, USA
… multiple events of subsurface dolomitization and quartz cementation within dissolution voids (vugs). A detailed petrographic study has therefore been undertaken to reconstruct the complex history of post-depositional subsurface physical and chemical alteration (diagenesis) of the Potosi and …
