“…However, chemical EOR is not expected to impact world's oil production for at least two decades, if it is ever implemented at commercial scales. Despite the growing research interest on chemically assisted methods (e.g., spontaneous imbibition, wettability modifiers and ITF reductions) and surfactant polymer (SP) flooding to improve oil recoveries in carbonate formations, these projects are not expected to impact global oil production in the near future [60]. Nanotechnology has the potential to have a positive effect on the chemical EOR process.…”

Chemical flooding is of increasing interest and importance due to high oil prices and the need to increase oil production. Research in nanotechnology in the petroleum industry is advancing rapidly, and an enormous progress in the application of nanotechnology in this area is to be expected. The nanotechnology has been widely used in several other industries, and the interest in the oil industry is increasing. Nanotechnology has the potential to profoundly change enhanced oil recovery and to improve mechanism of recovery, and it is chosen as an alternative method to unlock the remaining oil resources and applied as a new enhanced oil recovery method in last decade. This paper therefore focuses on the reviews of the application of nanotechnology in chemical flooding process in oil recovery and reviews the applications of nanomaterials for improving oil recovery that have been proposed to explain oil displacement by polymer flooding within oil reservoirs, and also this paper highlights the research advances of polymer in oil recovery. Nanochemical flooding is an immature method from an application point of view.

“…There was more remaining heavy oil in the porous medium when the TPG was higher. To minimize the impact of the TPG on the production of a heavy oil field, thermal recovery methods are recommended to reduce the viscosity of heavy oil and to increase the mobility of heavy oil [67,68], which should be followed by a reduction in the TPG to improve heavy oil recovery. reagents/materials/analysis tools; Xiankang Xin wrote the paper.…”

Abstract:In this paper, physical experiments and numerical simulations were applied to systematically investigate the non-Newtonian flow characteristics of heavy oil in porous media. Rheological experiments were carried out to determine the rheology of heavy oil. Threshold pressure gradient (TPG) measurement experiments performed by a new micro-flow method and flow experiments were conducted to study the effect of viscosity, permeability and mobility on the flow characteristics of heavy oil. An in-house developed novel simulator considering the non-Newtonian flow was designed based on the experimental investigations. The results from the physical experiments indicated that heavy oil was a Bingham fluid with non-Newtonian flow characteristics, and its viscosity-temperature relationship conformed to the Arrhenius equation. Its viscosity decreased with an increase in temperature and a decrease in asphaltene content. The TPG measurement experiments was impacted by the flow rate, and its critical flow rate was 0.003 mL/min. The TPG decreased as the viscosity decreased or the permeability increased and had a power-law relationship with mobility. In addition, the critical viscosity had a range of 42-54 mPa·s, above which the TPG existed for a given permeability. The validation of the designed simulator was positive and acceptable when compared to the simulation results run in ECLIPSE V2013.1 and Computer Modelling Group (CMG) V2012 software as well as when compared to the results obtained during physical experiments. The difference between 0.0005 and 0.0750 MPa/m in the TPG showed a decrease of 11.55% in the oil recovery based on the simulation results, which demonstrated the largely adverse impact the TPG had on heavy oil production.

“…The main parameter limits for chemical flooding are summarized according to actual field applications survey, which is very useful for the following pilot design and risk assessment (Al-Adasani and Bai 2010; Alvarado and Manrique 2010;Li et al 2008;Taber et al 1997). Then the parameters of main oil zones are compared with the technical limit (Table 1).…”

“…In general, sandstone reservoirs show a highest potential to implement chemical EOR methods. However, chemical EOR projects have made a relatively small contribution to the world's oil production during the last decades (Alvarado and Manrique 2010). Especially, China is the country with the largest oil production resulting from chemical EOR projects (Chang et al 2006;Gu et al 1998;Hongyan et al 2009;Pu 2009).…”

Because of high oil price and technology advancement in recent years, chemical EOR is becoming an important option for maintaining sustainable efficient development for mature reservoirs in the future. In this paper, an integrated numerical simulation approach is adopted for Palouge oilfield in South Sudan for chemical EOR feasibility evaluation. The chemical EOR methods are preliminarily screened for the main oil-bearing zones, and the advantages and disadvantages for chemical flooding are analyzed by comparing technical parameter limits with oilfield parameters. Specifically, the pilot oil zone and areal position selection was determined using a comprehensive method, which is based on zonal injection plan and application experiences. Chemical EOR simulation is performed for sensitivity analysis and different scenarios prediction. Three technical indicators are employed to evaluate the EOR efficiency. Some key physiochemical factors with uncertainty are also analyzed in detail, and this will provide unusual useful information for comprehensive feasibility evaluation. The proposed technical evaluation procedure provides a helpful guidance for chemical EOR feasibility assessment in other analogous reservoirs.
