Dolomitization of Ordovician Kelimoli carbonates linking to shale oil formation, western Ordos Basin: new insights from magnesium and strontium isotopes

Frontiers in Earth Science
Deciphering the dolomitization process has great significance for high-quality hydrocarbon reservoir prediction in carbonate successions. The Ordovician Wulalike Formation provides shale oil in the western Ordos Basin, while lateral-contact marine ...

A Critical Look at Dolomitization by Evaporative Fluids

Dolomitization models commonly invoke a replacement reaction between evaporative fluids and a limestone precursor. These models assume that evaporative fluids are powerful dolomitizing agents, particularly when Ca-sulfate precipitation drives up the Mg ...

The Impact of Dolomitization on Reservoir Quality Evolution of the Fractured Carbonate Reservoir Upper Cretaceous, Onshore Abu Dhabi Oilfield, U.A.E

, 2017
Dolomitization, as part of diagenesis of carbonate rocks, may or may not significantly enhance reservoir quality of the altered sediments. In this context, a diagenesis study was performed on Upper Cretaceous reservoir of an onshore oil field, Abu Dhabi,

Petrographic and isotopic evidence for late-stage processes in sulfuric acid caves of the Guadalupe Mountains, New Mexico, USA

International Journal of Speleology, 2012
Caves of the Guadalupe Mountains have experienced many modifications since their final phase of sulfuric acid speleogenesis several million years ago. Petrographic and geochemical data reveal details of the change from H2SO4 to CO2-dominated reactions ...
