A controller for controlling apparatus for performing a wellbore intervention or process, a corresponding processing device and method for simulating and/or controlling consecutive flow of a plurality of fluids in a wellbore of arbitrary geometry, the method involving forming, using or providing a model or simulation of the wellbore, the model or simulation representing the wellbore as a plurality of segments or portions; determining and/or providing one or more friction pressure drop components associated with at least one portion or segment of the wellbore for the plurality of fluids; and calculating pressure drop values for at least one segment or portion and/or between segments or portions using the one or more friction pressure drop components. Preferably, the method involves determining a pressure response during acid stimulation. |
