Surfactants and nanoparticles (NP) frequently act as stabilizers for oil and water emulsions. There is a need to investigate whether such NP stabilized emulsions (also known as Pickering emulsions) require different treatment for break-up, as compare

Summary An experimental and theoretical investigation of surfactant-stabilized oil/water emulsion characteristics was carried out under water sweep (WS) and oil sweep (OS) conditions. Both hydrophilic and hydrophobic surfactants were used, with conce

Solid particles are encountered in oil and gas pipelines when producing from unconsolidated reservoirs. Solid accumulation can lead to increase in pressure loss, erosion, corrosion, production decline etc. The stratified flow regime is most vulnerabl

Emulsions are ubiquitous in oil production operations and in general undesirable for various reasons. These include increased pressure losses leading to reduced oil productivity, pipeline and other equipment corrosion, as well as separation difficult

During the process of petroleum production and transportation, equipment such as pumps and chokes will cause shear effects which break the dispersed droplets into smaller size. The smaller droplets will influence the separator process significantly a

Foaming is a common phenomenon in the petroleum industry. Foams can be desirable for drilling applications, whereby the cutting bits are lubricated, and cuttings are carried up to the surface. However, foam can be undesirable for production operation

Foaming can hinder gas-liquid separation, therefore, it is desirable to break the foam upstream of separation facilities. There are different methods to breakup foam, including chemical (utilizing defoaming agent), mechanical (such as cyclones), and
