A compressible two-phase model with pressure-dependent well-reservoir interaction
(Journal article; Peer reviewed, 2013)This paper deals with a two-phase compressible gas-liquid model relevant for modeling of gas-kick flow scenarios in oil wells. To make the model more realistic we include a natural pressure-dependent well-formation ... -
Genuine two-phase flow dynamics with a free interface separating gas-liquid mixture from gas
(Journal article; Peer reviewed, 2013)This paper deals with a two-phase compressible gas-liquid model relevant for modeling of gas-kick flow scenarios in oil wells. To make the model more realistic we include a natural pressure-dependent well-formation ... -
Global weak solutions for a compressible gas-liquid model with well-formation interaction
(Journal article; Peer reviewed, 2011-10)Abstract. The objective of this work is to explore a compressible gas-liquid model designed for modeling of well °ow processes. We build into the model well-reservoir interaction by allowing °ow of gas between well and ... -
Global weak solutions for a gas liquid model with external forces and general pressure law
(Journal article; Peer reviewed, 2011)In this work we show existence of global weak solutions for a two-phase gas-liquid model where the gas phase is represented by a general isothermal pressure law, whereas the liquid is assumed to be incompressible. To make ... -
Weak solutions for a gas liquid model relevant for describing gas-kick in oil wells
(Journal article; Peer reviewed, 2011)The purpose of this paper is to establish a local in time existence result for a compressible gas-liquid model. The model is a drift-flux model which is composed of two continuity equations and one mixture momentum equation ...
