Modelling of transient gas-liquid flow and pigging in pipes [PDF]

open access: yes, 1999
More and more transient gas-liquid operations in pipes are being successfully applied in the oil and gas industry. Pigging in two-phase pipelines, to remove liquid accumulation or for cleaning purposes, is an important transient operation.

A study of gas lift on oil/water flow in vertical risers [PDF]

open access: yes, 2014
Gas lift is a means of enhancing oil recovery from hydrocarbon reservoirs. Gas injected at the production riser base reduces the gravity component of the pressure drop and thereby, increases the supply of oil from the reservoir. Also, gas injection at
