“…Combined chemical EOR flooding shows a great potential in reservoirs with low/medium oil viscosity since it takes advantages of both chemical species and uses their synergy to increase the sweeping efficiency. This EOR process should be started as early as possible in the reservoir, but considering that the associated costs are significantly higher than those from waterflooding or secondary recovery, all the uncertainties from the oil field should be properly assessed before starting the tertiary recovery operations. − , Moreover, it is considered that the use of polymeric surfactants will also represent a breakthrough in chemical EOR processes, and future research on this topic is advised.…”

“…Hence, in this study the combined technique, polymer and surfactant, including also their synergy and interactions in the porous medium, is proposed. The objective of this paper is then to present a novel simulator for a two-phase, five-component model, including the analysis of the injection procedure, presenting different time gaps between chemical slugs in order to draw conclusions about how to maximize the recovery factor. ,,− …”

The use of standard enhanced oil recovery (EOR) techniques allows for the improvement of oilfield performance after waterflooding processes. Chemical EOR methods modify different properties of fluids and/or rock to mobilize the remaining oil. Moreover, combined techniques have been developed to maximize the performance by using the joint properties of the chemical slugs. A new simulator is presented to study a surfactant–polymer flooding, based on a two-phase, five-component system (aqueous and oleous phases with water, petroleum, polymer, surfactant, and salt) for a 2D reservoir model. The physical properties modified by these chemicals are considered as well as the synergy between them. The analysis of the chemical injection strategy is deemed vital for the success of the operations. This plays a major role in the efficiency of the recovery process, including the order and the time gap between each chemical slug injection. As the latter is increased, the flooding tends to behave as two separate processes. Best results are found when both slugs are injected overlapped, with the polymer in first place which improves the sweeping efficiency of the viscous oil. This simulator can be used to study different chemical combinations and their injection procedure to optimize the EOR process.

“…Altogether, the three relevant dimensionless parameters to describe the problem are thus ξ 1 , ξ 2 and r. Note that comparing the local visco-capillarity and chemistry, one can get rid of L in Eqs. (11) and obtains:…”

“…The detailed understanding of such two-phase flows is essential to the development of a sustainable economy, as illustrated in hydrology through CO 2 sequestration in the soil [6,7], and groundwater contamination [8][9][10]. As of today, the most important industrial application in terms of economical impact remains the extraction technique in the oil industry, which consists in injecting pressurized water in the reservoir to sweep away the hydrocarbon from the rocks [11]. Accordingly, most of the studies describing two-phase flows in porous media are carried out in the context of imbibition -wetting fluid displacing non-wetting fluid -or drainage -non-wetting fluid displacing wetting fluid -, an approach relevant to several but not all situations.…”

We study the problem of the transformation of a given reactant species into an immiscible product species, as they flow through a chemically active porous medium. We derive the equation governing the evolution of the volume fraction of the species, in a one-dimensional macroscopic description, identify the relevant dimensionless numbers, and provide simple models for capillary pressure and relative permeabilities, which are quantities of crucial importance when tackling multiphase flows in porous media. We set the domain of validity of our models and discuss the importance of viscous coupling terms in the extended Darcy's law. We investigate numerically the steady regime and demonstrate that the spatial transformation rate of the species along the reactor is non-monotonous, as testified by the existence of an inflection point in the volume fraction profiles. We obtain the scaling of the location of this inflection point with the dimensionless lengths of the problem. Eventually, we provide key elements for optimization of the reactor.

The production of oil and gas by subsea production systems has been tested and performed for several fields. The first steps of the primary oil and gas processing, which were held in Stationary Production Units ( number of sensitivity analyzes is performed by changing the main parameters that affect the flow pressure drop: water-oil ratio, gas-oil ratio, production flow rate and API gravity. At the end of this work, the simulation results of two hypothetical subsea scenarios that have flow assurance problems and the solution of these problems with the installation of oil-water subsea separation systems are presented.
