Paper presented at the SPE EOR Conference at Oil and Gas West Asia, March 26–28, 2018
Paper Number: SPE-190352-MS
... Abstract The depression of the current global oil market renders the majority of chemical EOR projects worldwide unprofitable, especially in china. Therefore, economic alternative technologies must be quickly developed. This paper evaluated the potential of a smart pre-formed emulsion flooding...

Paper presented at the SPE EOR Conference at Oil and Gas West Asia, March 26–28, 2018
Paper Number: SPE-190406-MS
... Abstract Emulsion, as an oil displacement and conformance control system, provides essential contribution for enhanced oil recovery (EOR). However, conventional flooding systems, which form large emulsion droplets compared to the pore size of porous media in formation, usually encounters...

Paper Number: SPE-190377-MS
... Abstract Chemical flooding has been suggested as an efficient conformance control technique to develop many of thin post-CHOPS heavy oil reservoirs in Western Canada. In-situ formation of oil in water emulsions due to the effect of surfactant/natural soap has been reported as the main mechanism...

... amounts of in-situ surfactants compared to Na 2 CO 3 , which is the most frequently used alkali performer. Additionally, in most concentrations the micro emulsion viscosities were lower. Thus, potassium carbonate might be an interesting candidate in future alkali applications. Upstream Oil & Gas...

Paper Number: SPE-190440-MS
... Abstract Surfactants and nanoparticles are materials being widely used for enhanced oil recovery (EOR). Surfactants are mainly used to reduce the interfacial tension between oil and water which could form a stable film of emulsion between these two immiscible fluids. Also, nanotechnology...

... be achieved by ASP flooding after water flooding in Daqing oilfield. Heavy alkyl benzene sulfonate (HABS) and petroleum sulfonate were employed as the main strong alkali and weak alkali surfactants, respectively. However, due to the high w/o interface activity of such surfactants, severe emulsion has also...

In Alaska, where we possess detailed fluid, well and reservoir information, we have correlated this regime with hydraulic units with incomplete voidage replacement. The WOR ∼ 1 flow regime can be interpreted as a water-in-oil emulsion flow which is intrinsic...
