Several surfactants and nanoparticles were examined to identify the most effective foam formulation. Foam stability at the reservoir temperature and ambient...

... viscosity and density, wettability modification, and others, nanoparticles have gained attention for their various applications in oil recovery. Even though a number of factors have been studied in the past in relation to increasing foam stability with nanoparticles, the ideal conditions for achieving...

... Abstract Foam stability primarily determines the efficiency of foam induced conformance control especially when fractures exist in formations. In this work, a well-defined nanocellulose fibrils (NCF) strengthened CO 2 foam (NCF-st-CO 2 foam) was proposed aiming to improve the conformance...

... in oil recovery. Key to the success of foam EOR is the effectiveness of foam for gas-mobility control, which is evaluated in terms of foam stability and strength (reflected through its apparent viscosity - the inverse of total relative mobility of phases). Foam-oil displacement in reservoirs...

... in a representative oil-wet fracture generates very poor foams, unlike classical porous media (sandpacks, rock core samples). This poor rejuvenation of foam evidences that foam flow in fracture strongly differs from observations in porous matrix and highlights the need for long-term foam stability. In long tubings...

... 2010 , Kapetas, van El et al. 2014 ), very limited attempts have been made to tackle the problem in the presence of oil ( Myers and Radke 2000 ). In this work we first summarized various criteria proposed in the past to evaluate foam stability in the presence of oil and their respective evidence...

... and viscoelastic surfactants (VES) to improve foam stability when these foams are used as EOR fluid. This study investigates the stability of alpha olefin sulfonate (AOS) foam for different foam solutions in the presence of nanoparticles and viscosifiers (VES). To achieve this objective, foam stability tests were...

... transfer barrier during the loading process. In this work, novel aqueous foams have been formulated by incorporating special type of clay nano-particles in an aqueous solution of surfactants and polymers. Experiments to investigate the foam stability and VOC emission were carried out in a bench-scale foam...

... Abstract This paper reports adsorption/desorption kinetics and equilibrium onto Berea sandstone for a surfactant used as a CO2-water foaming agent. Also, foam stability of the surfactant is compared before and after adsorption/desortion has occurred. Results show that this surfactant's...

... Abstract Foam stability and rheology are important parameters for foam used as a drilling fluid in underbalanced drilling. A low density fluid is one way to avoid formation damage or borehole fracturing when the reservoir has a low pore pressure, or is depleted. However foamed drilling fluids...
