Liquid loading experiments with tube wall modifications
conference paper
This paper discusses the multiphase flow mechanism responsible for gas-well liquid loading. It demonstrates that the conventional idea of droplet flow reversal (Turner et al. (1)) does not capture reality and that actual observations are better described by film flow reversal phenomenon. The benefits of different types of tubing wall modification have been evaluated via small-scale lab testing. Most promising, hydrophobic coating of tubing reduces the gas rate below which liquid loading occurs by about 50%. The benefits of hydrophobic coating are translated to representative field conditions. © BHR Group 2011.
