The usual presence of some liquids can reduce production even faster. This paper describes the problem of liquid accumulation in a gas well. Recognition of gas-well liquid-loading problems and solution methods are discussed. 1. Introduction. Gas wells producing dry gas have a low flowing bottomhole pressure (FBHP), especially for low-rate wells. of gas wells, it is probable that some liquids cannot be transferred outside by the use of gas flow and this results in fall of liquids to the down-hole and gradual loss of well. For solving this problem, the well must be drained by the use of gas lift or hydraulic pumps. Thus the subject of accumulation of liquids in gas wells is considered as.

Petroleum foam or oil foam or simply foam in oilfield typically refers to the foam that forms in hydrocarbon production processing separators as a result of forced and rapid oil/gas separation. Foaming risk is related to crude oil properties - density, bulk viscosity, surface tension, asphaltene and resin contents and gas properties play a role as well. A frequent problem in gas plants is foaming, which occurs during the gas sweetening process. This problem is usually the result of contaminants entering the process and improper operating conditions. The first mitigation action is normally the addition of a chemical antifoaming agent. The second is to find the cause and eliminate it. However, antifoaming agents can be an effective interim—or.

The use of foam produced by surfactants can be effective for gas wells that accumulate liquid at low rates (Exhibit 1).

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.

As natural gas is extracted, reservoir pressures decline, resulting in, reduced gas flow rates. Gas wells normally have associated water.

When velocities are low enough, liquid holdup is higher in this flow regime. The gas production will decrease. There are several ways to solve this problem, i.e. mechanical or chemical methods. For Cited by: Foaming agents provide a means to reduce the density of the liquid so that it can be removed from the well with the gas flow.

The purpose of the foaming agent is to generate foam from the gas flow. Natural gas bubbling through the liquid column containing foaming agent produces foam, which helps removing liquid from the well, Fig.

A major problem of mature gas wells is liquid accumulation in the well bore. The foam for gas well deliquification is generated by gas flow in the tubing.

A dynamic foaming test (DFT) apparatus, shown schematically in Fig. 2, was used to measure the liquid unloading efficiency of foamer apparatus, which is a modified version of a setup from the US Bureau of Mines, consists of a medium porosity frit (10–20 μm), through which a sustained nitrogen gas flow rate is sparged, a mL glass column, a condensing arm leading the Cited by: 5.

Foamers are surfactants that are specifically designed to regain or increase gas production in maturing gas wells.

Deliquifying or bringing liquids to the surface allows increased gas production, improves well production consistency, and revives non-producing wells. Stable foam circulation has proven an efficient method of removing sand from producing wells, replacing bailing.

Many completion and removal jobs are difficult under low pressured reservoirs where conventional fluid circulation results in severe loss of fluids to the producing zone.

Surface flowing tubing pressure and production will decline as the low-pressure gas wells load-up with water and eventually cease to produce.
