The production of excess water during oil recovery creates not only a major technical
problem but also an environmental and cost impact. This increasing problem has forced oil …

In recent years, much attention has been paid to the addition of nanoparticles (NPs) into the
surfactant foam structure to form durable foams. Although surfactant foam as an enhanced …

Global demand for energy is increasing day by day rapidly as a result of the population,
industrial, and economic growth of developing countries, especially in emerging market …

Foam, a versatile underbalanced drilling fluid, shows potential for improving the drilling
efficiency and reducing formation damage. However, the existing literature lacks insight into …

Foams are used as an enhanced oil recovery (EOR) method to reduce the mobility of
injected gaseous phases. However, foam stability is often compromised under harsh …

Rheological models are usually used to predict foamed fluid viscosity; however, obtaining
the model constants under various conditions is challenging. Hence, this paper investigated …

Foam stability tests were performed using sodium dodecyl sulfate (SDS) surfactant and SiO
2 nanoparticles as foaming system at different asphaltene concentrations, and the half-life of …

Oil reservoirs are nearing maturation, necessitating novel enhanced oil recovery (EOR)
techniques to meet escalating global energy demands. This demand has spurred interest in …

Underbalanced foam drilling (UBFD) represents a pivotal technique aimed at enhancing
safety and operational efficiency within drilling operations. Despite its recognized benefits …

Improved/enhanced oil recovery (IOR/EOR) has the potential to unlock a significant amount
of residual and trapped oil from existing and new hydrocarbon resources. This chapter …
