The potential of the CO 2 soaking procedure has been generally acknowledged as a valid
way to advance the tight rock oil recovery. Over the last decade, a significant number of Huff …

After hydraulic fracturing, shale reservoirs often undergo rapid production declines during
depleted development, resulting in a low cumulative production. CO2 huff and puff emerges …

The effects of fracture density, miscibility and production scheme on CO 2 enhanced oil
recovery (EOR) in fractured reservoirs were investigated. A series of CO 2 injection …

The performance of CO 2 injection into a semi-heavy oil reservoir was investigated at
reservoir conditions, using highly permeable sandstone in a complete series of PVT tests …

An experimental study was conducted to improve understanding of the interactions between
bypassed oil and CO 2, and to investigate their contribution to bypassed oil recovery. First …

A series of core-flood tests were performed, together with nuclear magnetic resonance
measurements of the initial and residual oil saturation states in the cores, to investigate the …

Shale oil reservoirs pose significant challenges for efficient recovery due to their tight and
heterogeneous characteristics. This study investigates the potential of CO 2 Huff-n-Puff …

Abstract Supercritical CO 2 (ScCO 2) foam could benefit both industry revenue generation
through EOR and climate control with CO 2 storage/utilization. Relative to aqueous soluble …

Several phenomena could recover the bypassed oil in matrixes and low permeable areas,
among them; Marangoni is the most unfamiliar one in fluid flow model. This mechanism …
