“…Some studies have been performed in the field of enhanced oil recovery using ultrasonic waves (Wang and Xu 2015;Wang and Zhou 2004). Experimental models for ultrasonic-based enhanced oil recovery have been presented and indicated that ultrasonic waves can greatly increase production (Mohsin and Meribout 2015;Wegener et al 2001;Amro et al 2007). Changes in crude oil characteristics due to ultrasonic wave irradiation are also evaluated (Shi et al 2017).…”

Because inorganic scales reduce permeability near wellbores, they cause an additional pressure drop in this region (skin damage) and reduce production. NaCl precipitation, particularly in gas-producing wells, is one of the formation damage problems which impair the permeability. The use of backwashing water not only requires a large quantity of water, but is also inefficient. This study examined the effect of the ultrasonic waves in NaCl scale removal. Twenty core samples with different permeabilities were saturated with NaCl. After precipitation of NaCl within the cores, the samples were first subjected to water injection and then to water injection with ultrasonic wave radiation. At each stage, the permeability of cores was measured and recorded. Experimental results reveal that applying ultrasonic waves restores the permeability of cores more than water injection alone. In samples with permeability lower than 20, 30-100, 100-700 md and cores with permeabilities higher than 1000 md, ultrasonic waves recover permeability to 80, 42, 87 and 81%, respectively. In contrast, water injection alone improves permeability to 29, 18.5, 62 and 77%, respectively. The effect of these waves is much more obvious than water injection alone in low-permeability cores. SEM images from cores show that ultrasonic waves destroy the structure of deposits of sodium chloride. This phenomenon is due to propagation of these waves and the resulting temperature increase in the surroundings, which leads to the increased solubility of these scales. After exposure to ultrasonic waves, sodium chloride deposits inside the induced fractures of cores could be removed from the fracture, whereas water injection alone could not wash and remove the deposits from the fracture. According to the results of this paper, ultrasonic waves can be used as a novel and efficient technology in gas wells to remove inorganic scales in the near-wellbore region.

“…Thus, there is great interest in the development of more efficient technologies. Over the last few years, the use of physical EOR techniques have been reported, especially those based on ultrasonic treatment [11][12][13][14][15]. We have developed an ultrasound-assisted method that operates in the wellbore perforation zone with the simultaneous creation of a zone of lower pressure.…”

In the last two decades, an increasing interest of academy and industry in the development of enabling technologies for process intensification has been paid. The main bottle neck for scientists and engineers to apply non-conventional technologies at industrial levels, such as high-intensity ultrasound, is the scaling up. Power ultrasound is proving to be a front-runner and offers a wide range of profitable applications. Although most examples reported by patents and scientific literature are not yet an industrial reality, few applications are recognised as the best available techniques for big scale production. Eloquent examples are reviewed in this article.

“…Overall the complexity of such process hindered theoretical modelling of ultrasonic enhanced oil recovery technique. For example, Mohsin and Meribout [36] developed a model which involves heat and acoustic modules to predict the performance of ultrasound on oil recovery in a single phase (oil) flow process and they tested their model with their experimental data. They also found that there was a pressure increase due to ultrasonic waves which led to improved oil recovery.…”

CO 2 flooding process as a common enhanced oil recovery method may suffer from interface instability due to fingering and gravity override, therefore, in this study a method to improve the performance of CO 2 flooding through an integrated ultraosund-CO 2 flooding process is presented. Ultrasonic waves can deliver energy from a generator to oil and affect its properties such as internal energy and viscosity. Thus, a series of CO 2 flooding experiments in the presence of ultrasonic waves were performed for controlled and uncontrolled temperature conditions.Results indicate that oil recovery was improved by using ultrasound-assisted CO 2 flooding compared to conventional CO 2 flooding. However, the changes were more pronounced for uncontrolled temperature conditions of ultrasound-assisted CO 2 flooding. It was found that ultrasonic waves create a more stable interface between displacing and displaced fluids that could be due to the reductions in viscosity, capillary pressure and interfacial tension. In addition, higher CO 2 injection rates, increases the recovery factor in all the experiments which highlights the importance of injection rate as another factor on reduction of the fingering effects and improvement of the sweep efficiency.
