Review of surfactant-assisted chemical enhanced oil recovery for carbonate reservoirs: challenges and future perspectives
Oil reserves Original oil in place Carbonate formations Surfactants Chemical enhanced oil recovery
2018/4/2
A significant fraction of the conventional oil reserves globally is in carbonate formations which contain a substantial amount of residual oil. Since primary and secondary recovery methods fail to yie...
Experimental and Simulation Studies on Verification of Oil Recovery Enhancement by Film Flow
Oil recovery Film flow Relative permeability Three-phase flow
2009/7/28
Oil recovery enhancement of gasflood by oil film flow was verified. Film flow phenomena involve the formation of a thin film by residual oil blobs in water-wet media which becomes continuous between ...
Improved Heavy Oil Recovery by VAPEX Process in the Presence of Vertical and Horizontal Fractures
VAPEX Fractured reservoir Conventional reservoir Solvent
2009/7/28
Vapor extraction (VAPEX) is an important process for recovery of heavy oil and bitumen. In this work, the VAPEX process is studied experimentally in a rectangular physical model. The setup was constr...
Development of Streamline-based Heat Transport Model for Thermal Oil-recovery Simulation
Heat transport Operator splitting technique Thermal simulator
2009/7/27
The streamline method was extended to thermal oil-recovery simulation by developing an appropriate heat transport model based on the streamline method for implemention into a thermal recovery simulat...
Recent advances and prospects in Microbial Enhanced Oil Recovery (MEOR)—Outline of MEOR and microorganisms for MEOR
Microbial Enhanced Oil Recovery (MEOR) high performance microbes for MEOR
2009/4/8
Recently, a sharp skyrocket in crude oil has become a destabilizing factor to the world economy. For instance, all over the world including China and India have been competing against one another for...
Imbibition Assisted Oil Recovery
Assisted Oil Recovery
2008/10/29
Imbibition describes the rate of mass transfer between the rock and the fractures. Therefore, understanding the imbibition process and the key parameters that control the imbibition process is crucial...
Effect of Temperature, Wettability and Relative Permeability on Oil Recovery from Oil-wet Chalk
Temperature Relative Permeability
2008/10/27
It is customary, for convenience, to use relative permeability data produced at room temperature. This paper shows that this practice underestimates oil recovery rates and ultimate recovery from chalk...
