Abstract
A method for moving fluid through a pipe in a wellbore includes placing at least two different fluids in the pipe and in an annular space between the pipe and the wellbore. Fluid is pumped into the pipe at a rate to achieve a desired set of conditions. Using a predetermined volume distribution of the annular space, an axial position of each of the at least two fluids in the annular space during the pumping the displacement fluid is calculated.
