A simplified two-phase flow model using a quasi-equilibrium momentum balance
Aarsnes, Ulf Jakob Flø; Ambrus, Adrian; Di Meglio, Florent; Vajargah, Ali Karimi; Aamo, Ole Morten; van Oort, Eric (Journal article; Peer reviewed, 2016)We propose a simple model of two-phase gas–liquid flow by imposing a quasi-equilibrium on the mixture momentum balance of the classical transient drift-flux model. This reduces the model to a single hyperbolic PDE, describing ... -
Real-time estimation of reservoir influx rate and pore pressure using a simplified transient two-phase flow model
Ambrus, Adrian; Aarsnes, Ulf Jakob Flø; Vajargah, Ali Karimi; Akbari, Babak; van Oort, Eric; Aamo, Ole Morten (Journal article; Peer reviewed, 2016)The ability to perform accurate pore pressure and reservoir inflow estimation during a kick incident is necessary, particularly when drilling in formations with narrow pressure margins. Currently available techniques for ...
