The investigation of the mechanism of CO 2/water flooding in ultralow-permeability oil
reservoir is critical to the enhanced oil recovery. In this study, a series of core flooding …

Asphaltene precipitation is often accompanied by CO 2 injection in tight light oil reservoirs.
In tight oil reservoirs, the traditional studies of reservoir damage by asphaltene precipitation …

CO 2 miscible flooding is a prospective production method to enhance oil recovery (EOR),
especially in low-permeability reservoirs. However, there is a lack of comprehensive and …

CO 2 huff-n-puff can store CO 2 and improve the recovery of tight oil reservoir. The
asphaltene precipitation produced by the interaction of CO 2 and oil causes damage to tight …

CO 2 injection into shale oil reservoirs can effectively enhance recovery while
simultaneously realizing geological storage. However, shale oil recovery by CO 2 injection …

The implementation of CO 2 enhanced oil recovery (EOR) projects for tight reservoir
development has the dual effects of economic benefits and carbon storage. Matrix …

This study aims to investigate the impact of CO2 huff-n-puff after CO2 flooding on recovery
efficiency in tight sandstone reservoirs. The experimental methodology involved the …

Oil production performance in the unconventional reservoirs is significantly affected by the
flooding agent and occurrence environment. In this study, the in-situ stress and …

Due to the problem of low formation pressure in shale oil reservoirs of the Ordos Basin, oil
production decreases rapidly during primary production stage. It is crucial to maintain …

Multiphase flow affected by fractures is essential for enhanced oil recovery in ultralow-
permeability reservoirs. In this study, CO 2/water flooding of intact and fractured cores was …
