“…This phenomenon can be attributed to the rising pressure causing the density of the gas to increase and subsequently reducing surface tension. 37,38 Surface tension is responsible for holding the gas bubbles within the liquid phase and is a critical factor in the foam stability. When the surface tension is lowered, it becomes easier for the gas bubbles to form and stabilize in the liquid, resulting in improved foamability.…”

“…Nitrogen was selected as the gas phase for the experiments because of its extensive application in foam drilling operations in the field . A synthetic seawater solution with a total salinity of 67.70 g/L and both monovalent and divalent cations was prepared using ACS-grade salts listed in Table . To mimic a typical drilling environment, the pH of the foaming solutions was adjusted to a range of 9–10 using a pH buffer solution containing 5 M potassium hydroxide (KOH).…”

Foam, a versatile underbalanced drilling fluid, shows potential for improving the drilling efficiency and reducing formation damage. However, the existing literature lacks insight into foam behavior under high-pH drilling conditions. This study introduces a novel approach using synthesized seawater, replacing the conventional use of freshwater on-site for the foaming system's liquid base. This approach is in line with sustainability objectives and offers novel perspectives on foam stability under high-pH conditions. Experiments, conducted with a high-pressure, high-temperature (HPHT) foam analyzer, investigate how pressure and temperature affect foam properties. The biodegradable foaming agent ammonium alcohol ether sulfate (AAES) is employed. Results demonstrate that the pressure significantly impacts foam stability. Increasing pressure enhances stability, reducing decay rates and promoting uniform bubble sizes, especially at lower temperatures. This highlights foam's capacity to withstand high-pressure conditions. Conversely, the temperature plays a substantial role in foam decay, particularly at elevated temperatures (75 and 90 °C). Decreased liquid viscosity accelerates the liquid drainage and foam decay. While pressure mainly influences the AAES foam stability at temperatures up to 50 °C, temperature becomes the dominant factor at higher temperatures. Temperature's impact on foamability is minimal under constant pressure, maintaining consistent gas volume for maximum foam height. However, foam stability is sensitive to temperature variations, with increasing temperature leading to a more significant bubble size increase gradient. These findings stress the importance of considering temperature effects in foam drilling, particularly in deep and high-temperature environments. AAES foam exhibits stability at lower temperatures, making it suitable for surface and intermediate drilling. Understanding temperature-induced changes in foam structure and bubble size is essential for optimizing performance in high-temperature and deep drilling scenarios.

“…However, due to the limitation of experimental equipment, it was hard to observe the morphology of the foam under supercritical CO 2 in general. Al-Darwish et al (2022) and Al-Darwish et al (2023) used Duomeen TTM and Armovis VES surfactant mixtures and found that the average radius of bubbles increased as a function of time and the pressure increase resulted in fine-textured bubbles and smaller bubble sizes. However, the pressure only increased to 7 MPa in this work.…”

CO2‐in‐water (C/W) foams have attracted much attention given their eco‐friendliness in recent years. However, limited surfactants were able to effectively adsorb at the supercritical CO2–water (C–W) interface considering the weak solvent strength of CO2, especially at high temperatures. Herein, attempts have been made to design suitable CO2 foaming agents by evaluating the influence of proportions of anionic and cationic surfactants and the affinity between aminopropyl methyl siloxane (APSi) and CO2. Through systematical foamability and foam stability experiments, together with the measurements of C–W equilibrium and dynamic interfacial tensions, the adsorption and stabilization mechanisms of sodium alpha olefin sulfonate (AOS)‐APSi aqueous dispersions on the CO2 foam films are revealed. Excellent foam properties were observed at AOS/APSi mass ratio of 9:1, in which initial foam height (h0) and half‐life period (t1/2) first increased and then decreased with increasing pressure, whereas the interfacial tension decreased with increasing pressure. The results indicate that the interaction of anionic and cationic head‐groups contributes to accelerating the surfactant adsorption rate from bulk to the C–W interface, enhancing foamability and stabilizing foam. Besides, the AOS/APSi mass ratio of 8:2 shows a good affinity for CO2 at 15 MPa, of which h0 is 26% higher and t1/2 is 60% slower than AOS alone. Furthermore, the initial mean bubble area of both 9:1 and 8:2 AOS/APSi mixtures was around half that of AOS alone. This work broadens the design of novel surfactant methodologies including CO2 foam, providing a theoretical guidance for the application of CO2 on enhanced‐oil‐recovery technologies.
