Abstract This study presents a new multiphase flow model with transient heat
transfer and pressure coupling to simulate HTHP (high temperature and high pressure) sour gas “kicks” phenomena. The model is intended to support the estimation of wellbore temperature and pressure when sour gas kicks occur during
drilling operation. The model considers sour gas solubility, phase transition and
effects of temperature and pressure on the physical parameters of drilling fluid.
Experimental data for a large-diameter pipe flow are used to validate the model.
The results indicate that with fluid circulation, the annulus temperature with H2S
kicks is… More >
