Prestack Seismic Velocity Ratio Evaluation of a Mixed Siliciclastic–Carbonate Formation: Case Study from the Strawn Group on the Eastern Shelf Texas

open access: yesEnergies, 2023
Although a mixed carbonate–siliciclastic system of the Strawn Group on the Eastern Shelf in King County, Texas, USA provides excellent hydrocarbon reservoirs, facies variability and reservoir properties within such systems are not well understood.

Hydrothermal Calcite Precipitation in Veins: Inspired by Experiments for Oxygen Isotope Fractionation between CO2 and Calcite from 1 °C to 150 °C

open access: yesApplied Sciences, 2023
The oxygen isotope ratios of minerals are important for estimating the formation temperature of hydrothermal deposits. Calcite is generally found in most mining districts.

Carbon Anode in Carbon History [PDF]

open access: yesMolecules, 2020
This study examines how the several major industries, associated with a carbon artifact production, essentially belong to one, closely knit family. The common parents are the geological fossils called petroleum and coal. The study also reviews the major developments in carbon nanotechnology and electrocatalysis over the last 30 years or so.

Enhancing Computational Precision for Lattice Boltzmann Schemes in Porous Media Flows

open access: yesComputation, 2016
We reassess a method for increasing the computational accuracy of lattice Boltzmann schemes by a simple transformation of the distribution function originally proposed by Skordos which was found to give a marginal increase in accuracy in the original ...

Identification and Current Palaeobiological Understanding of “Keratosa”-Type Nonspicular Demosponge Fossils in Carbonates: With a New Example from the Lowermost Triassic, Armenia

open access: yesLife, 2022
Structures similar to fossilized nonspicular demosponges have been reported in carbonates throughout the Phanerozoic and recently in rocks dating back to 890 Ma ago.

Discriminating cool-water from warm-water carbonates and their diagenetic environments using element geochemistry: the Oligocene Tikorangi Formation (Taranaki Basin) and the dolomite effect [PDF]

open access: yes, 2004
Fields portrayed within bivariate element plots have been used to distinguish between carbonates formed in warm- (tropical) water and cool- (temperate) water depositional settings.

THE GEOLOGICAL SIGNIFICANCE OF MAJSTORSKA CESTA – A HISTORICAL ROAD ON VELEBIT MT. WITH A SPECIAL REVIEW OF JURASSIC CARBONATE ROCKS

open access: yesRudarsko-geološko-naftni Zbornik, 2020
Majstorska Cesta is a historical road along Velebit Mt., NW of Sveti Rok, preserved in its original state since opening in 1832 and therefore added to the cultural heritage list of the Republic of Croatia in 2007.

Pliocene Te Aute limestones, New Zealand: Expanding concepts for cool-water shelf carbonates [PDF]

open access: yes, 2003
Acceptance of a spectrum of warm- through cold-water shallow-marine carbonate facies has become of fundamental importance for correctly interpreting the origin and significance of all ancient platform limestones.

Characterization and evaluation of ultra-deep fracture-pore tight sandstone reservoirs: A case study of Cretaceous Bashijiqike Formation in Kelasu tectonic zone in Kuqa foreland basin, Tarim, NW China

open access: yesPetroleum Exploration and Development, 2014
Taking the Cretaceous Basijiqike Formation sandstone reservoirs in the Kuqa foreland basin as an example, this paper studies the characterization and evaluation methods of fracture-pore (fracture-primary pore and fracture-dissolution pore) ultra-deep ...
