Enhancing Recharge in the Edwards Aquifer, Texas: Measures, Outcomes, and Lessons for Karst Aquifers

Groundwater, EarlyView.
Abstract Managed aquifer recharge is a widely adopted method that involves storing excess water underground for future use. While managed aquifer recharge has been applied globally to different aquifer types, its use in karst aquifers is less common due to the unique hydrogeological characteristics of these systems, including high permeability ...

Episodic dolomitization of Paleozoic limestones in the Kinta Valley, Malaysia: Implications on porosity evolution and reservoir properties

Energy Geoscience, 2021
Carbonates undergo a variety of physical, mineralogical, chemical changes during depositional and post-depositional stages that are of interest to exploration geologists and sedimentologists.

Feldspar Albitization With Implications for Reservoir Quality Evolution of Eocene Turbidite Sandstones in Offshore Espírito Santo Basin, Eastern Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT The diagenetic albitization of plagioclase and K‐feldspar grains is a transformative process that significantly alters sandstone's detrital composition and formation water chemistry, impacting reservoir quality. In this study, Eocene turbidite sandstones from the offshore Espírito Santo Basin, Brazil, were investigated to elucidate the role of

Visible, near‐, and thermal infrared spectra of asteroid Bennu samples: Relationship to and implications for remote sensing of carbonaceous asteroids

Meteoritics &Planetary Science, EarlyView.
Abstract Remote spectroscopy is used to characterize the mineralogy and infer the history of planetary bodies. Carbonaceous asteroids, such as B‐type (101955) Bennu, represent the earliest stages of planet formation. B types have a blue (negative) spectral slope and comprise <5% of asteroids.

Applciation of UVA oblique photogrammetry in multi-scale characterization of Yunhuatan shoal reservoir in the Maokou Formation, central Sichuan Basin: A case study on the Hongyan outcrop section, Huaying

Carsologica Sinica
In recent years, guided by the concept of facies-controlled reservoirs, high-quality porous dolomite reservoirs of platform margin facies in Member 2 of the Maokou Formation (Mao-2 Member) have been discovered on the northern slope of Central Sichuan and

The Ames impact structure, Oklahoma: New radioisotopic constraints and implications for North American impact chronology

Meteoritics &Planetary Science, EarlyView.
Abstract The Ames impact structure (Oklahoma) is thought to have formed during the Ordovician Meteor Event, based on conodont biostratigraphy of its crater fill. Here, U–Pb zircon dates from its impact‐melt portion, conducted using secondary ion mass spectrometry and laser ablation–inductively coupled plasma–mass spectrometry (n = 37 spots), yield a ...

A Triassic chronostratigraphic and palaeogeographic framework for the Utsira High area, northern North Sea: Reconstructing a basin‐scale drainage divide

Sedimentology, EarlyView.
ABSTRACT The Triassic succession of the northern North Sea comprises a series of interbedded sandstones, mudstones and conglomerates deposited under a fluctuating arid to semi‐humid climate regime, which are often difficult to correlate regionally due to differing lithostratigraphic schemes and poor age control. Despite existing regional studies on the

Influence of structural setting, depositional environment and differential diagenesis on reservoir quality of the Xixiangchi formation in the central and southern Sichuan Basin, China

Frontiers in Earth Science
The Middle-Upper Cambrian Xixiangchi Formation (504 - 488 Ma) dolomite in the central-southern Sichuan Basin constitutes significant hydrocarbon reservoirs, though their complex genetic mechanisms remain inadequately constrained.

Reservoir characteristics and forming conditions for the Middle Triassic Leikoupo Formation in the western Sichuan Basin, China

Journal of Natural Gas Geoscience, 2019
In the past few years, petroleum exploration in the Leikoupo Formation in the western Sichuan Basin of China has obtained fruitful achievements, but composite research on the carbonate rock reservoir and its control factors are lagging behind, which ...
