Micro-influencing mechanism of permeability on spontaneous imbibition recovery for tight sandstone reservoirs

Petroleum Exploration and Development, 2017
Taking the Chang 8 tight sandstone reservoir of the Yanchang Formation of Fuxian area in Ordos Basin as an example, the influencing mechanism of permeability on imbibition recovery in tight sandstone was explored by spontaneous imbibition experiment ...

Too Hot, Too Cold, Just Right: Thermal Modulating Capacity of Different Sources of Groundwater Discharge to Salmon‐Bearing Streams

River Research and Applications, EarlyView.
ABSTRACT Groundwater discharge plays a key role in maintaining habitat suitability for cold‐water fish by generating streamflow and modulating temperatures. However, the thermal influence depends on groundwater source depth and how far groundwater travels from the point of discharge to a receiving stream.

Intelligent Continuum Micromachines in Complex Confined Spaces

SmartBot, EarlyView.
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

Enhancing Recharge Beneath Low‐Permeability Landscapes with Small‐Diameter Drywells: Token Creek, WI

Groundwater, EarlyView.
Shallow, small‐diameter drywells provide enhanced recharge in rural landscapes, bypassing the low infiltration rates caused by low permeability surficial soils and high ET rates. One year of monitoring data show several recharge events and overall high water quality.

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

Tight sandstone reservoirs in lacustrine environments: review and perspectives

International Geology Review
This study systematically investigated the characteristics, formation mechanisms, and development potential of global lacustrine tight sandstone reservoirs to address the urgent demand for unconventional hydrocarbon exploration. A combination of literature review and case studies from representative basins, including the Uinta Basin (U.S.A.), San Jorge

Coupled plagioclase dissolution and K‐feldspar overgrowth precipitation preserve anomalously high permeability in deeply buried sandstones

Sedimentology, EarlyView.
ABSTRACT This study investigated the formation mechanism responsible for anomalously high permeability (AHP) observed in the Eocene sandstones at depths from 3824 to 3832 m in the Huizhou Sag, Pearl River Mouth Basin, China, using helium porosity and permeability measurements, thin section, scanning electron microscopy, electron probe X‐ray ...

Architecture of fluvio-deltaic sandbodies: the Namurian of Co. Clare, Ireland, as an analogue for the Plio-Pleistocene of the Nile Delta [PDF]

, 2003
Understanding and predicting the size, shape and internal architecture of sandbodies is of fundamental importance in hydrocarbon exploration. High quality hydrocarbon reservoirs are often formed in deltaic environments where there is a complex interplay ...

Differential controlling on the deep tight sandstone reservoirs: Insight from the second member of lower Triassic Xujiahe Formation in Xinchang area, western Sichuan basin, China

Journal of Natural Gas Geoscience
With advancements in deep exploration, the deep tight sandstone gas reservoir has become a significant exploration field. However, it remains challenging to develop on a large scale due to the unclear distribution of relatively high-quality reservoirs ...
