Interfacial tension (IFT) reduction and wettability alteration (WA) are important enhanced oil
recovery (EOR) mechanisms that help displace residual oil from the reservoir. Many studies …

Primary oil recovery from fractured unconventional formations, such as shale or tight sands,
is typically less than 10%. The development of an economically viable enhanced oil …

The wetting characteristics of shale rocks at representative subsurface conditions remain an
area of active debate. A precise characterization of shale wettability is essential for …

The breakthrough of shale oil in North America led to a worldwide energy revolution. Shale
reservoirs show multiscale properties and a large proportion of nanopores compared to …

油/水/岩石间的固液界面特征是影响致密/页岩储层渗吸行为的关键, 尤其对于界面张力达到超低
且具有增溶乳化作用的渗吸体系, 亟待明确其界面作用机制与渗吸行为的关系. 以延长组7 段+ 8 …

Abstract Analysis of flowback data, gathered immediately after fracture stimulation, can be
performed to understand the fluid flow physics, investigate flow regimes, and obtain early …

Several researchers have investigated the dominant recovery mechanisms among the
wettability alteration and interfacial tension (IFT) reduction during surfactant flooding in …

渗吸驱油是裂缝性油藏的有效驱油方式, 但渗吸驱油的机理一直没有得到统一的认识,
应用相关知识对其进行深入研究, 取得以下认识. 渗吸有同向渗吸和逆向渗吸之分 …

We reviewed and evaluated the wettability of organic-rich shale plugs from 6 wells drilled in
the Duvernay Formation, which is a self-sourced reservoir. We divided our samples into …

Surfactant treatments play a crucial role in formation cleaning and wettability alteration for
reservoirs characterized by low porosity and permeability. One effective approach to …
