As a promising method of carbon emission reduction, carbon capture, utilization and storage
(CCUS) is an important technology to achieve carbon neutrality. CO 2 geological storage is …

The production of excess water during oil recovery creates not only a major technical
problem but also an environmental and cost impact. This increasing problem has forced oil …

Leakage is one of the most serious challenges for the safe production of high‐pressure gas
wells for its high risks, including abnormal annular pressure, natural gas accumulation, and …

Excessive water production is one of the main problems of mature reservoirs, which reduces
hydrocarbon production and economic reservoir lifetime, and may pose severe …

Gel systems are widely used as plugging materials in the oil and gas industry. Gas
channeling can be mitigated by reducing the heterogeneity of the formation and the mobility …

Abstract Carbon Capture and Storage (CCS) and CO 2 Enhanced Oil Recovery (CO 2-EOR)
are crucial in reducing CO 2 emissions. They focus on both climate change mitigation and …

Mineral precipitation or scale formation in reservoirs, injection, and production wells is
recognized as an obstacle for hydrocarbon recovery. Significant production drops and …

Summary Preformed‐particle‐gel (PPG) treatments have been successfully used in injection
wells to reduce excessive water production from high‐temperature, high‐salinity fractured …

The key objective of well cementing has always been to provide zonal isolation in oil, gas,
and carbon dioxide (CO 2) storage wells to ensure safety and prevent environmental …

In this study, we present an innovative intelligent polymer sealant designed to mitigate CO2
leakage during underground geological storage (CCUS). This sealant is formulated by cross …
