“…Emulsification is a common phenomenon in the SP flooding and also an important mechanism for EOR [9,14,19]. In order to evaluate the efficiency of chemical emulsifying the oil, a series of emulsification experiments are conducted, according to the description of the experimental method in Section 2.4.…”

This study aims to analyze the influence of viscosity and interfacial tension (IFT) on the recovery in heterogeneous reservoir and determines the main controlling factors of the polymer-surfactant (SP) flooding. The influence of the salinity and shearing action on the polymer viscosity and effects of the surfactant concentration on the IFT and emulsion behavior between chemical agent and oil were studied through the static and flooding experiments. The results show that increasing the concentration of polymer GF-11 (HPAM) can reduce the influence of the salinity and GF-11 has high shear-resistance property. In the condition of the Jilin Oilfield, the oil/water IFT can reach 10 −3 mN/m when the surfactant concentration is 0.3 wt%. The lower the IFT is, the easier the emulsion of SP and oil is formed. Seven flooding experiments are conducted with the SP system. The results show that the recovery can be improved for 5.02%-15.98% under the synergistic effect of the polymer and surfactant. In the heterogeneous reservoir, the contribution of oil recovery is less than that of the sweep volume.

“…Generally, acidic compounds in the crude oil are drifted to the interface by the injected alkali and reacts with aqueous phase hydroxide to form surfactant in situ (Wang et al 2009). Since this kind of flooding procedure is simple and inexpensive, it continues to receive much attention for EOR (Wanli et al 2000). Alkali Surfactant Polymer (ASP) flooding gathers the benefits of all three types of chemicals and develop the volumetric sweep efficiency.…”

Enhanced Oil Recovery Techniques for Indian Reservoirs

2015

The overall oil production worldwide has declined due to the increase in maturity of the oil reservoirs. In developing countries like India, the oil production and demand plays a crucial role for the development of economy of the country. However, the domestic crude oil production is insufficient to meet the requirement for energy. Thus, there is a big challenge to minimize the gap between the demand and supply for crude oil. Several methods to enhance oil recovery have been developed to increase the production from matured reservoirs and are referred to as enhanced oil recovery (EOR) methods. This chapter discusses in detail about the various EOR methods, their applicability, and the screening criteria for various reservoir types. The EOR methods are further discussed in Indian contexts. This chapter also summarizes the details of various oilfields in India. The chapter will in general, help to understand the recent trends and the need of EOR for Indian oil reservoirs.

“…Three ASP corefloods were modeled using simplified model and the proposed model can easily be implemented in any existing surfactant/polymer model. Simulation experiments were conducted to examine the effects of ASP on w/o [39] and stability o/w separation [40] in produced water from ASP flooding. The emulsion stability of water produced from ASP ooding was investigated by conducting settling experiments and measuring the oil-water interfacial properties [41].…”

This is a review article on the subject of combining tertiary oil recovery methods like alkaline, surfactant and polymer flooding in order to achieve the synergetic effect out of the different impacts which are caused by these chemicals, affect oil and water filtration in the reservoir and increase oil recovery. In the article the main theoretical concepts of EOR (enhanced oil recovery) are summarized, mechanism of alkaline, surfactant and polymer flooding technologies are explained referring to the research works which had strong contribution to the development of the tertiary oil recovery methods. Formulation of alkaline/surfactant/polymer (ASP) chemical formula for EOR is discussed as well. Importance of numerical simulation and core flood laboratory experiments for the successful implementation of ASP technologies explained in the paper. Finally several examples of ASP flooding applications throughout the world projects are presented.
