... recovery methods are being invest-tigated, as a result, only in-situ combustion is more potential and seems feasible to enhance oil recovery for such reservoir. To investigate the feasibility of in-situ combustion, reactor experiment and combustion tube experiment have been carried out at first...

... Abstract Using acoustic energy in enhanced oil recovery is not a new idea but yet is categorized as an unconventional method. In previous studies at our institution, the effect of ultrasonic radiation on capillary imbibition recovery of light oil from a water wet medium was widely investigated...

... through the water fingers and bypass significant volumes of continuous oil. It has been shown in other works that alkali and/or surfactant injection can lead to improved heavy oil recovery compared to waterflooding, but researchers have proposed different reasons for this response. This work summarizes...

... and the optimum time to start steam flooding after steam soak by economic oil/steam ratio. The optimum time to start steam flooding is at the 7th cycle. There exists a peak recovery efficiency of steam flooding when the length of separation section ratio is 0.15-0.2. Oil recovery rate can be enhanced...

... Abstract The Court Bakken heavy oil reservoir (17 °API) in Saskatchewan has been under successful water flooding for many years. Laboratory studies have indicated that caustic flooding can enhance heavy oil recovery significantly after water flooding. This paper describes design...

... Abstract Heavy oil recovery by VAPEX appears to be a promising IOR technique as it uses less energy than SAGD and, if CO 2 is injected, can also provide a means of disposing of excess CO 2 in the subsurface. Nonetheless field application of this process has been limited due to concerns...

... to understanding the displacement of heavy oil by water is to consider the oil recovery after breakthrough. This oil is produced at high water cuts, and under negligible pressure gradients. Oil is therefore recovered by water imbibition into the water-wet sand. By varying the injection rates and the permeability...

... analysis was conducted using thermal simulation. The parameters analyzed were vertical well spacing, injection steam rate, well flowing pressure, and horizontal length of the well pair. The effect on the oil recovery from the angle of dip in the reservoir and the orientation of the well pair with regard...

... Abstract In heavy-oil recovery, although steam injection has no alternative in many circumstances, it may not be an efficient process under certain reservoir conditions. These conditions include deep reservoirs, where steam injection may turn out to be ineffective hot-water flooding due...

The mechanisms of SMWSHP are as follows: (1) Injecting steam into several wells at the same time can avoid...

... model was used that incorporated typical rock and fluid properties for these fields. Simulation results indicate oil recovery after 10 years are 5.7–27% OIIP with TINBOP, i.e. 57–93% higher than conventional cyclic steam injection (3.3–14% OIIP). Steam-oil ratios are also decreased with TINBOP (0.8–3.1...
