Churn-Annular foam flow: experiments and modelling
conference paper
Foam assisted lift is a deliquification method in the oil and gas industry, which aims to prevent or postpone countercurrent gas-liquid flow in maturing gas wells or to assist in removing downhole accumulated liquids. The creation of foam reduces the density of the liquid that needs to be transported and postpones the transition from annular to churn flow to lower gas velocities, which improves the upward transport of liquid carried by foam. This paper presents a model predicting the foam flow behavior in annular flow conditions down to the transition from annular to churn flow, with which the onset of liquid loading is computed.
