... with the formation as well as gelation time and kinetics. Single-phase DPR fluid injectivity through Berea cores is excellent. At relatively high watercuts in water-wet cores, two-phase DPR-fluid/oil injectivity is good and even better in oil-wet cores regardless the watrecut. At relatively low watercuts in water...

...). In this paper, we present the results of a series of two-phase and three-phase gas injection (drainage) and oil injection (imbibition) core flood experiments for an gas/oil system at near-miscible (IFT= 0.04 mN.m ‒1 ) conditions. Two different cores; a high-permeability (1000 mD) and a lower permeability (65 mD...

..., a 55% (average) reduction in gel volume occurred in pores of all detected size ranges, thus leading to a relatively high permeability to oil. In porous polyethylene, reduction in gel volume occurred mainly in small pores. Because the first oil injection after gel placement did not reduce gel volume...

... showed an incremental oil recovery of up to 2000 bbl and a GOR reduction of 80%. The oil production rate increased by 328%, therefore the application cost of 5500 $ US was recovered by the second day of production. We measured a sudden increase of the GOR 3-1/2 months after the heavy oil injection...
