Interplay between Rock Permeability and the Performance of Huff-n-Puff CO2 Injection [PDF]

ACS Omega, 2020
The CO2 huff-n-puff experiments are often conducted on a rock sample with a given permeability. However, there is a need for understanding the production performance of CO2 huff-n-puff over a range of rock permeability values. In this study, CO2 huff-n-puff corefloods were conducted by using 30 cm long artificial cores over a permeability range between

Re-Fracturing vs. CO2 Huff-n-Puff Injection in a Tight Shale Reservoir for Enhancing Gas Production [PDF]

Frontiers in Energy Research, 2023
Field production data indicate that the shale gas production rate decreases sharply after a few years of the first fracking. Feasible enhanced gas recovery (EGR) approaches are very necessary to be investigated.

Enhanced oil recovery by low-salinity water spontaneous imbibition (LSW-SI) in a typical tight sandstone formation of mahu sag from core scale to field scale

Petroleum, 2021
Accelerating mass exchange between matrix and fractures is the essence of enhanced oil recovery (EOR) in tight formations after natural depletion. Low salinity water (LSW) injection has been commercially-proven in conventional reservoirs EOR, with scale ...

Experimental study on the expansion of foamy bitumen for CO2 huff-n-puff process

Unconventional Resources
This study investigates the feasibility of cold in-situ bitumen recovery using a CO2 huff-n-puff process, focusing on foam swelling and expansion under reservoir conditions. Experiments simulate CO2 injection into Canadian bitumen at pressures of 2–4 MPa
