Porosity enhancement potential through dolomitization of carbonate reservoirs, a case of study from the Euphrates Graben fields, East Syria

open access: yesPetroleum, 2023
The dolostones and dolomitic limestones of the lower Cretaceous Judea formation are a key target of hydrocarbons in most of the Euphrates Graben fields.

Dolomitic Microfossil Preservation in a Cryogenian Microbial Reef, Arkaroola (South Australia). [PDF]

open access: yesGeobiology
ABSTRACT Microbial dolostones that now form the Arkaroola reef, northern Adelaide Rift Complex, and were deposited during the Cryogenian interglacial period, display a wide range of meso‐scale stromatolite morphotypes in outcrop. Microcharacterisation involving optical microscopy, combined scanning electron microscopy and energy dispersive spectroscopy

Carbonate Clumped Isotopes (Δ47) in Cenozoic “Island Dolostones”: Dolomitization Driven by Modified Seawater at Earth‐Surface Conditions

open access: yesGeochemistry, Geophysics, Geosystems
Dolomite [CaMg(CO3)2] is abundant throughout the geological record and constitutes a major component of many ancient carbonate platforms, yet the mechanisms responsible for its formation under Earth‐surface conditions are equivocal.

Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

open access: yesLethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Fault-controlled dolomitization in the Montagna dei Fiori Anticline (Central Apennines, Italy): record of a dominantly pre-orogenic fluid migration [PDF]

open access: yesSolid Earth, 2019
The Lower Jurassic platform and basinal deposits exposed in the Montagna dei Fiori Anticline (Central Apennines, Italy) are pervasively affected by dolomitization.

Multiphase dolomitization mechanisms of the Cambrian upper Changping Formation, North China Platform, China

open access: yesFrontiers in Earth Science, 2023
The Cambrian dolomite reservoirs of the North China Platform offer good exploration prospects, but their occurrence and the impacts of dolomitization on reservoir quality are not yet clearly understood.

Dolomitization evolution and its effects on hydrocarbon reservoir formation from penecontemporaneous to deep burial environment

open access: yesPetroleum Exploration and Development, 2022
Aiming at the scientific problem that only part of dolomite acts as dolomite reservoir, this paper takes the multiple dolomite-bearing formations in the Tarim and Ordos basins, NW China and Sichuan Basin, SW China as the study object, by means of mineral

Petrology and geochemical characteristics of dolomite in the Middle Permian Maoukou Formation, central Sichuan

open access: yesPetroleum Research, 2017
Dolomites of the Maokou Formation in the central Sichuan were mainly developed in the middle-upper part of Member 2 and the lower part of Member 3 of Maokou Formation, it could be divided into fine-to medium-grained calcareous dolomite, fine-to medium ...
