“…At first, Marathon Oil Company in the early 1960s presented the application of surfactants [5]. In this method, the surfactant would reduce the surface tension between water and oil phases; consequently, the capillary pressure would be reduced, and water could push the extra amount of oil [6,7]. Fu et al presented an experimental work, which discuses about the application of a cationic surfactant for EOR purposes.…”

“…Our literature review concludes that the in situ generated CO 2 Huff-n-Puff process with chemical compound surfactant could substantially improve oil recovery performance [27,28]. However, very limited research has been undertaken in this area, especially for the parametric analysis of the key operating variables for the improvement of oil recovery.…”

This paper presents the numerical investigation and optimization of the operating parameters of the in situ generated CO2Huff-n-Puff method with compound surfactant on the performance of enhanced oil recovery. First, we conducted experiments of in situ generated CO2and surfactant flooding. Next, we constructed a single-well radial 3D numerical model using a thermal recovery chemical flooding simulator to simulate the process of CO2Huff-n-Puff. The activation energy and reaction enthalpy were calculated based on the reaction kinetics and thermodynamic models. The interpolation parameters were determined through history matching a series of surfactant core flooding results with the simulation model. The effect of compound surfactant on the Huff-n-Puff CO2process was demonstrated via a series of sensitivity studies to quantify the effects of a number of operation parameters including the injection volume and mole concentration of the reagent, the injection rate, the well shut-in time, and the oil withdrawal rate. Based on the daily production rate during the period of Huff-n-Puff, a desirable agreement was shown between the field applications and simulated results.

“…The effect of this surfactant on IFT and contact angle of a similar system at the macro-scale was studied previously (Mirchi 2015). It was reported that the IFT and contact angle was decreased in the presence of surfactant indicative of the less water-wet surface (Mirchi 2015). During the last step, a small quantities of the same crude oil were added to the sample.…”

Spontaneous imbibition of treatment fluids into rock matrix during hydraulic fracturing is believed to be one of the major reasons for the early high productions from shale oil reservoirs. In this study, we integrated Focused Ion Beam-Scanning Electron Microscope (FIB-SEM) tomography and non-destructive X-ray nanotomography techniques to study the spontaneous imbibition of oil and brine solutions in shale nanopores. First, a piece of argon-polished reservoir mudrock sample was imaged at high resolution by SEM to find areas of interest. Then, small cylindrical rock sample (20 m diameter) was cut carefully using FIB. The cylindrical core sample was then cut free from the bulk rock sample and attached to the tip of a needle. The miniature core were transferred into an X-ray CT scanner and imaged prior to exposure to any fluids (dry state). Then spontaneous imbibition tests were performed using an in-situ flooding apparatus. In order to represent fluid invasion by hydraulic fracturing in shale oil reservoirs, first, crude oil doped with 2 wt.% iodooctane was introduced to the core followed by brine (15 wt.% NaI) spontaneous imbibition. In the next step, a solution of nonionic surfactant (0.1 wt.%) was added to the core sample and extra brine imbibition was observed. The sample was scanned (voxel resolutions of 64 nm) and the pore-fluid occupancy was explored at the end of each imbibition step. The results showed that both brine and oil imbibed into the core. Nonionic surfactant increased the recovery by about 15%. This might be as a result of lower IFT and contact angle, which also has been reported in the literature. Moreover, during the last test, oil also imbibed into the pore space, due to the fact that the surface became less water wet as a result of surfactant injection prior to this test.
