Alkaline flooding is a promising enhanced heavy oil recovery method. In this paper, this enhanced heavy oil recovery method is investigated in terms of its tertiary oil recovery potential and its effects on wettability alteration of the porous medium. Core flood tests show that the tertiary oil recovery can be greater than 10% of the initial oil in place (IOIP) by NaOH-only flooding or with NaOH and...
There are much collaboration and cooperation in the dynamic, multi-institutional virtual grid. Grid provides a good bridge between the resource users and the resource providers. Especially in the agent-based grid system, agents could provide services for the scheduling of applications that make grid resources better use. We have proposed a resource discovery mechanism with negotiation in grid environment...
In recent years, the study of the grid economy is becoming a new hot spot with the grid technology development. Lots of models and middleware have been proposed by scholars to improve the application of grid economy. In our previous research work we have proposed the resource pricing fluctuation module (RPFM) as a part of grid architecture for computational economy (GRACE). However, as nodes in the...
This study is aimed at developing an alkaline/surfactant-enhanced oil recovery process for heavy oil reservoirs with oil viscosities ranging from 1000 to 10,000mPas, through the mechanism of interfacial instability. Instead of the oil viscosity being reduced, as in thermal and solvent/gas injection processes, oil is dispersed into and transported through the water phase to production wells.Extensive...
For heavy oil reservoirs (with oil viscosities ranging from 1000 to more than 10,000mPas), primary production and waterflooding can only recover 5–10% of initial oil in place (IOIP) due to the unfavorable mobility ratio between water phase and oil phase. If heavy oil is dispersed in formation brine by a chemical injection, the mobility of oil can be greatly improved. In this study, sandpack flood...
