Foam is a colloidal system, defined as the dispersion of gas in a liquid. The liquid phase is continuous and external, whereas the gas phase is discontinuous and internal. The gas separates from the liquid by forming bubbles, thin walls, or borders that divide the gas phase from the liquid phase and are known as lamellae (Figure ). These films are usually stabilized by surfactants, polymers, and nanoparticles . The presence of surfactants, polymers, and nanoparticles helps to reduce the surface tension of the liquid film, allowing the bubbles to maintain their shape and stability . This unique structure gives foam its characteristic light and airy texture, making it useful in various applications such as wastewater treatment, food manufacturing, pharmaceuticals, cosmetics, firefighting, and Enhanced Oil Recovery (EOR). Figure : Foam structure Foam has been widely employed in the oil and gas industry, particularly as a drilling fluid during the drilling phase. Foam's lighter composition compared to traditional drilling fluids aids in reducing the hydrostatic pressure exerted on the formation . Additionally, foam exhibits excellent cuttings carrying capacity, facilitating the efficient removal of drilled cuttings from the wellbore . In acidizing operations, the use of foam is intended to enhance treatment efficiency, improve well productivity, and optimize reservoir stimulation . In hydraulic fracturing, foam can contribute to improved fracture extension, connectivity, fluid efficiency, and proppant distribution, thereby enhancing the effectiveness of the hydraulic fracturing process .
