The dynamic effects of variable pump flow rate, formation-influx distribution, blowout preventer (BOP) and choke closure, choke adjustments, and well stabilization are accounted for in the analysis of a kicking well by solution of the appropriate mass- and momentum-balance equations. In the gas/liquid regions, the system is modeled as separated flow. The mass-balance equations are solved for the gas and liquid separately, but the momentum equation is solved for the mixture. The model predicts the detailed flow and pressure response of the well at all times and wellbore locations during the kick. The model is currently capable of simulating a single kick in a vertical hole (surface or subsea with water-based mud and the bit on bottom. The drillers' method (DM), wait/weight (WW), or dynamic kill-control procedures for either a ''perfect controller'' (constant bottomhole pressure (BHP)) or for any of several choke-control procedures may be simulated.
