prediction of stand pipe pressure using a technical drilling simulator: a case study in south of iran

stand pipe prediction is a most important aspect of hydraulic design in drilling engineering. it is crucial to predict stand pipe pressure and pressure losses to be encountered in well planning. a drilling well in south of iran consider as a case study to determine the accuracy of stand pipe pressure prediction, rheological parameters affecting the pressure losses and impact of each of the parameters was studied with commercial drilling simulator. the results obtained using the four widely used rheological models namely the newtonian model, the bingham plastic model, the power law model and the herschel-bulkley model are presented. four rheological models are used to find out their ability of predicting spp with sufficient accuracy. the power law model is found to produce spp estimates considerably close to the measured values for the drilling data considered (oil base mud).
