Evaluation of pore-throat structures of carbonate reservoirs based on petrophysical facies division

Frontiers in Earth Science, 2023
After complex geological transformation, such as sedimentation, diagenesis, and tectonic transformation, carbonate reservoirs have developed multiple reservoir spaces with significant heterogeneity and various pore-throat structures, including pores ...

Diagenesis of tight sandstone and its influence on reservoir properties: A case study of Fuyu reservoirs in Songliao Basin, China

Unconventional Resources, 2023
Diagenesis is the primary cause of the densification of the Fuyu reservoir in Sanzhao sag, Songliao Basin. In this paper, the types of diagenesis, the influence of diagenesis on reservoir physical properties and the formation reasons of tight reservoir ...

Quantitative simulation of the densification process of sandstone reservoir in the Xu 3 Member of Xujiahe Formation in western Sichuan Depression, Sichuan Basin

地质科技通报, 2023
In order to clarify the densification process and quantitatively restore the porosity evolution of the Xu 3 Member sandstone reservoir in western Sichuan Depression, the diagenesis of the Xu 3 Member was system atically analyzed using thin sections ...

Testing the impact of diagenesis on the delta O-18 and delta C-13 of benthic foraminiferal calcite from a sediment burial depth transect in the equatorial Pacific [PDF]

, 2013
Stable oxygen and carbon isotope (O-18 and C-13) values measured in foraminiferal calcite are one of the primary tools used in paleoceanography. Diagenetic recrystallization of foraminiferal calcite can act to reset primary isotopic values, but its ...

Rock acoustics of diagenesis and cementation [PDF]

, 2021
We simulate the effects of diagenesis, cementation and compaction on the elastic properties of shales and sandstones with four different petro-elastical theories and a basin-evolution model, based on constant heating and sedimentation rates.

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

Lethaia, 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)
