CO<inf>2</inf>-responsive preformed gel particles with interpenetrating networks for controlling CO<inf>2</inf> breakthrough in tight reservoirs

Pu W.f.; Du D.j.; Fan H.c.; Chen B.w.; Yuan C.D.; Varfolomeev M.A. (2021)

Horizontal well re-fracturing of tight reservoirs triggers complex fractures, which induces severe gas channeling and low sweeping efficiency in CO2 flooding due to the significance difference in permeability between matrix ...
Experimental study of CO<inf>2</inf> huff-n-puff in a tight conglomerate reservoir using true triaxial stress cell core fracturing and displacement system: A case study

Pu W.f.; Du D.j.; Wang S.; Zeng L.; Feng R.; Memon S.; Sarout J.; Varfolomeev M.A.; Sarmadivaleh M.; Xie Q. (2021)

To reveal the enhanced oil recovery (EOR) potential of CO2 huff-n-puff in fractured tight conglomerate reservoirs, hydraulic fracturing combined with CO2 huff-n-puff experiments were conducted using a true triaxial stress ...
Experimental study on EOR potential of water-in-oil emulsion via CO<inf>2</inf>/N<inf>2</inf> triggered wormlike micelle solution

Du D.j.; Pu W.f.; Chen B.w.; Varfolomeev M.A.; Liu R. (2021)

Oil in water (O/W) emulsion flooding appears to be an effective method to boost oil production of mature oilfields, while few works have been done to investigate the enhanced oil recovery (EOR) potential of water in oil ...
Migration and plugging characteristics of polymer microsphere and EOR potential in produced-water reinjection of offshore heavy oil reservoirs

Jin F.y.; Yang L.y.; Li X.; Song S.y.; Du D.j. (2021)

Due to the strong heterogeneity, the infaust mobility ratio of offshore heavy oil reservoirs and the high cost of produced water treatment, a “green” in-depth profile control technology was proposed, which integrated ...
Novel preformed gel particles with controllable density and its implications for EOR in fractured-vuggy carbonated reservoirs

Jin F.y.; Jiang T.t.; Varfolomeev M.A.; Yuan C.; Zhao H.y.; He L.; Jiao B.l.; Du D.j.; Xie Q. (2021)

The pre-crosslinked gel particles has been perceived as an important alternative to improve oil recovery from fractured-vuggy carbonate reservoirs. However, it remains a great challenge for the applications in high temperature ...
