Evaluating the Efficacy of Low Salinity Waterflood and Electrokinetic Enhanced Oil Recovery in Mitigating Gas Condensate Banking

Energy Science &Engineering, EarlyView.
Left panel: Natural Depletion → sharp pressure decline → condensate bank builds → reduced gas rate. The schematics show the condensate bank around the producer. Middle panel: Low Salinity Water → brine injection → improved pressure support → piston‐like condensate displacement → higher gas rate.

Research on the Mechanism and Suppression Method of Gas Migration Velocity Under Gas Invasion Conditions in Ultra‐Deep Well Drilling

Energy Science &Engineering, EarlyView.
ABSTRACT During ultra‐deep well drilling, the narrow safety density window of the drilling fluid makes it prone to complex conditions such as gas invasion. The high‐temperature and high‐pressure environment causes changes in the properties of the drilling fluid, making the gas invasion process highly covert and increasing the difficulty of well control.

Resistivity Change Mechanism in the Carbon Dioxide Sequestration Process

Energy Science &Engineering, EarlyView.
This study explores the variation law, influencing factors, and mechanisms of resistivity in the interaction between CO₂ and saltwater. This study used a hollow PEEK conductor to simulate core pores. With excellent thermal stability, mechanical strength, and electrical insulation, its homogeneous, nonporous nature eliminates interference from rock ...

Obstetrics and gynecology devices designed for low‐ and middle‐income countries: A narrative review

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 71-80, April 2025.
Abstract There are many barriers contributing to poor health outcomes for women in low‐ and middle‐income countries (LMICs), one of which is the lack of necessary medical devices. Presently, the development of various kinds of devices intended to improve women's health outcomes specifically in LMICs remains underrepresented in the literature; therefore,

The mineral and isotopic signatures of glacially eroded sediments exported from Hudson Strait to the Labrador Sea during Hudson Strait Heinrich events H0 to H4

Journal of Quaternary Science, EarlyView.
ABSTRACT The sediment signature of glacial erosion products exported from Hudson Strait to the Labrador Sea during Hudson Strait Heinrich (HS‐H) events is evaluated using four distinct proxies: paired δ18Ο and δ13C data on the carbonate fraction, εNd and U–Pb isotopes in the silicate fraction, the mineral composition of the <2 mm bulk sediment fraction,
