为保持国家能源安全, 我国油气开发领域在常规油气藏维持产量进行剩余油挖潜的基础上,
积极推进非常规油气资源的勘探与开发. 致密油藏地质勘探资源储量高, 但储层条件差 …

The exploration and development of unconventional oil and gas become the hotspot in
worldwide petroleum industry at present and in the future time. The unconventional …

Unconventional oil and gas resources, such as shale gas and tight oil, are increasingly
important in the energy structure; however, these reservoirs have poor physical properties …

Recent reports have demonstrated that carbon dioxide (CO 2) injection can further raise the
oil recovery of fractured tight reservoirs after natural depletion, with major projects in …

Injection pressure, soaking duration, and depletion strategy are crucial operational
parameters for a successful gas Huff-n-Puff (HnP) pilot. There is limited experimental data …

Despite promising natural gas huff 'n'puff (HnP) field-pilot results, the dominant oil-recovery
mechanisms during this process are poorly understood. We conduct systematic natural-gas …

In this study, we use an analytical approach and the interpolation-supplemented lattice
Boltzmann method (ISLBM) to quantify convective and diffusive transport during CO 2 …

Hydrogen can be a critical part of the energy transition and salt caverns have been
considered for underground hydrogen storage. Although there have been some successful …

CO 2 convective mixing has been extensively studied for CO 2 dissolution in saline water
but very limited with the presence of oil. The objective of this work was to visually study the …

In this study, a robust and pragmatic technique has been developed for the first time to
quantify preferential and mutual mass transfer of gases-light oil systems at high pressures …
