“…A database with the feature of all-inclusiveness makes the constructed model to be applied for a wider ranges of operational conditions. In other words, the proposed model is not limited to a specific condition and can be employed for mathematical description of the interest phenomenon at different conditions [35,[44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62]. In present research, 431 datapoints of permeability reduction values as a function of temperature, differential pressure, volume of injected water, initial permeability, flowrate, and ionic concentrations of cationic species (i.e., strontium, calcium and barium) and anionic species (i.e., sulfate) is taken from the open literature (see Supplementary Material) [40][41][42][43].…”

Mineral scaling has been considered a great concern for developing the oil production from the underground petroleum reservoirs. One of the main causes of this phenomenon is known as the chemical incompatibility of injected brine, frequently sea water, with the reservoir brine leading to the deposition of various supersaturated salts such as calcium carbonate, calcium sulfate and barium sulfate. In present communication, an evolutionary approach namely, Gene Expression Programming (GEP), was employed for rigorous modeling of formation damage by mineral scaling of mixed sulfate salt deposition. At first, a large databank of damaged permeability datapoints as a function of injected volume, injection flowrate, temperature, differential pressure and ionic concentrations of the existing chemical species in the porous media was employed. In this regard, a user-friendly correlation was extended for the first time by the aforementioned technique in the literature. Professional evaluation of the suggested GEP-based model was implemented by different statistical parameters and appealing visualization tools. Having proposed the GEP-based correlation, statistical parameters of the Average Absolute Relative Deviation Percent (AARD%) of 0.640% and determination coefficient (R2) of 0.984 was calculated. Accordingly, it is demonstrated that the proposed model has a superior performance and great potential for efficient prediction of damaged permeability due to the mixed sulfate salt scaling. Moreover, the implemented outlier diagnosis technique verified the validity of the databank used for modeling, as well as the high robustness of the suggested model was confirmed. In conclusion, the developed correlation in this work can be of enormous practical value for skillful engineers and scientists in any academic study and industrial applications dealing with mixed salt deposition.

“…In this study, a new type of nanosilica material is synthesized based on the procedure described in the work of Choolaei et al (2012). We already used this nanoparticle during low salinity water injection to reduce fines migration (Moghadasi et al, 2019a). Lightweight sand proppants with an average mesh size of 50 (∼300 µm) and density of 1.6 g/cm 3 , and Kaolinite clays with an average size of 3 µm were purchased from Nano-Gostar Company, Khuzestan, Iran.…”

Hydraulic fracturing has emerged as one of the best and most economical methods for enhancing oil recovery from low permeability reservoirs. However, its performance will be negatively affected by fines migration due to the hydraulic fracturing process. In the present study, it has been tried to experimentally investigate the efficiency of synthesized nanosilica particles in reducing fines migration. To this end, two sets of static and dynamic experiments, namely glass bead funnel test and core displacement analysis, were implemented, respectively. In the static test, increasing the soaking time and addition of nanosilica led to the clearer effluent fluid, resulting in fewer concentrations of clay particles in solution. When the mixture of nanosilica and glass beads was available in the solution, a higher differential pressure was obtained during a dynamic condition in comparison to only glass beads, which means the lower permeability of the porous media. Moreover, Derjaguin-Landau-Verwey-Overbeek theory was applied to demonstrate the clay particles absorption on the sand proppants surfaces. Consequently, it was observed that the use of nanosilica particles mixed with sand proppant can effectively reduce fines migration; thereby, it can enhance the hydraulic performance of the fracturing operation.

As a fixed reservoir rock property, pore throat size distribution (PSD) is known to affect the distribution of reservoir fluid saturation strongly. This study aims to investigate the relations between the PSD and the oil–water relative permeabilities of reservoir rock with a focus on the efficiency of surfactant–nanofluid flooding as an enhanced oil recovery (EOR) technique. For this purpose, mercury injection capillary pressure (MICP) tests were conducted on two core plugs with similar rock types (in respect to their flow zone index (FZI) values), which were selected among more than 20 core plugs, to examine the effectiveness of a surfactant–nanoparticle EOR method for reducing the amount of oil left behind after secondary core flooding experiments. Thus, interfacial tension (IFT) and contact angle measurements were carried out to determine the optimum concentrations of an anionic surfactant and silica nanoparticles (NPs) for core flooding experiments. Results of relative permeability tests showed that the PSDs could significantly affect the endpoints of the relative permeability curves, and a large amount of unswept oil could be recovered by flooding a mixture of the alpha olefin sulfonate (AOS) surfactant + silica NPs as an EOR solution. Results of core flooding tests indicated that the injection of AOS + NPs solution in tertiary mode could increase the post-water flooding oil recovery by up to 2.5% and 8.6% for the carbonate core plugs with homogeneous and heterogeneous PSDs, respectively.
