Numerical modeling of cuttings transport with foam in horizontal wells

摘要

In this study, a 1-D unsteady-state two-phase mechanistic model of cuttings transport with foam in horizontal wells has been developed. The model is solved numerically to predict cuttings bed height as a function of the drilling rate, the gas and the liquid injection rates, the rate of gas and liquid influx from the reservoir, and the borehole geometry. Results of sensitivity analyses study are presented.
