Foaming oil and gas
Web1). Foam reduces the density and surface tension of the fluid column, which reduces the critical gas velocity needed to lift fluids to surface and aids liquid removal from the well. Compared to other artificial lift methods, foaming agents are one of the least costly applications for unloading gas wells. Foaming agents work best if the fluid in the WebA chemical defoamer is required to counteract foam formation while promoting degassing of fluids. Defoamers provide high cost efficiency, working at injection rates of just a few …

Websomewhat uncertain whether foam in these cases actually works by gas blockage and flow diversion, or whether it is better described as a “viscosifying agent” for the gas. Foams often forms in crude oil by adding foaming agents, it also formed as the crude oil pressure is reduced in the reservoir, well bore, tubing string or flow line. WebJun 9, 2015 · The use of foams is most advantageously applied during gas flooding or for reducing gas coning and cusping in one of two manners: Foams can be used to improve sweep efficiency and improve oil recovery during gas flooding (e.g., steam, CO 2, and hydrocarbon-miscible flooding).
WebGas Foams Gas Foams Description: Dedicated surfactants are used to generate foam in oil reservoirs, from near-wellbore to in-depth in the formation. These foams improve gas sweep efficiency in CO 2 (dense … WebJan 1, 2000 · The majority of the existing defoamers and antifoams used in the oil and gas processing facilities, most often than not, contain toxic components that are …

Amine gas treatment is a process that uses aqueous solutions of various alkylamines (known as amines) to dissolve and remove hydrogen sulfide and carbon dioxide from the refinery sour gases, producing ‘sweet gas’. This leads to the process being known as ‘gas sweetening’, but it is also known ...
WebMar 23, 2011 · The best way to remove the liquid loading using foaming agents is to inject them downhole, via a dedicated injection line, and exploiting the natural gas flow that makes easier the formation of the foam. Often the well completion doesn't consider the presence of a chemical injection line installed outside the production string.
