... and fluid communication between the wells. For super heavy oil reservoirs in Fengcheng project in China, since the pay zone has low thermal conductivity and extremely high oil viscosity, establishing the temperature profile required for SAGD conversion using conduction as the only heating mechanism...

... Abstract In spite of CO 2 mobility reduction during CO 2 and surfactant solution co-injection, CO 2 -foam flooding in heavy oil reservoirs has relatively poor sweep efficiency due to the high viscosity the oil. Therefore, reducing the oil viscosity is necessary to improve CO 2 -foam sweep...

... Abstract EOR of deep waterflooded reservoir with low porosity and permeability is challenged by low heat efficiency of conventional thermal process. Conventional chemical process like surfactant flooding also has some risk because of high oil viscosity and water channeling along fractures since...

... expected (6 bars higher). Oil viscosity of the recombined oil was verified on line during injection, by measuring the pressure drop through a calibrated capillary tube within the set-up. Table 1 Main PVT characteristics of the oil Pb 37.2 bars GOR 10.8 v/v Oil viscosity...

... significant synergistic EOR effect in steam and flue gas co-injection because of the foamy oil flow, improvement in heating and sweeping efficiency and gravity assisted drainage, besides of the combined reduction in oil viscosity by heating and gas solution. Flue gas plays an important role in co-stimulation...

... the final one to plugging high permeability zones. Microbes can produce diverse metabolites thereby modifying the oil-water IFT in an oil reservoir. This study attempts to investigate the effect of microbial metabolites on the oil viscosity and IFT under reservoir P/T conditions. A reservoir fluid with 20...

... Abstract The Pelican Lake heavy oil field located in northern Alberta (Canada) has had a remarkable history since its discovery in the early 1970s. Initial production using vertical wells was poor because of the thin (less than 5m) reservoir formation and high oil viscosity (600 to over...
