Special Issue Information

Dear Colleagues,

The main method to recover heavy oils and bitumen is an in situ steam-based method, e.g., steam-assisted gravity drainage (SAGD). However, some challenges, such as low sweep efficiency, high costs, and environmental issues, still hinder the further application of this technology. There exists a need for an improved method for recovering residual oils after performing steam injection.  Chemicals, i.e., surfactant (including non-symmetrical molecules and others), polymer, nanofluid, and foaming agents, have promising potential to improve the performance of heavy oil recovery methods. This Special Issue focuses on the challenges associated with each of the abovementioned chemicals and steam-based recovery methods to provide the scientific evidence needed to determine whether the chemical assisted steam co-injection process is an immediate part of the solution, or whether further research is needed to improve this technology. Topics of interest include but are not limited to the following: phase behavior of surfactant/nanofluid (including symmetry analysis)/polymer and heavy oil, the stability and mixing of different phases, mathematical modeling, molecular dynamics simulation, the numerical simulation of such processes, new chemical-steam co-injection development, the application of data analytics, environmental evaluation, economical assessment, and pilot/field test studies.

It is essential to have an adequate understanding of the fluid-structure in a porous medium since this gives direct information about the processes necessary to extract the liquid and the likely yield. The concept of symmetry is one of the petroleum engineering issues that has been used to provide an analytical analysis for modeling fluid dynamics through porous media, which can be beneficial to validate the experimental field data. Tight reservoirs regarding their unique reservoir characterization have always been considered as a challenging issue in the petroleum industries. In this paper, different injectivity scenarios which included chemical and thermal methods were taken into consideration to compare the efficiency of each method on the oil recovery enhancement. According to the results of this experiment, the recovery factor for foams and brine injection is about 80%, while it is relatively 66% and 58% for brine-carbon dioxide and brine-nitrogen, respectively. Consequently, foam injection after water flooding would be an effective method to produce more oil volumes in tight reservoirs. Moreover, KCl regarding its more considerable wettability changes has provided more oil production rather than other scenarios. Full article
