Standpipe pressure remains among the parameters that affect the safe and successful process of the drilling activity. In this study, the rate of penetration, weight on bit, revolutions per minute, torque, dog leg, mud rheology and well hydraulics have all been considered during the development of the different presented models. The obtained results from the developed models were compared with the real values of the standpipe pressure obtained from the pressure transducers. This paper aims to analyze the comparison between the standpipe pressure values obtained from the pressure transducers and those from multiple regression models developed using a combination of the drilling parameters and frictional pressure drops using the Herschel-Bulkley rheological model. Nondimensionalization and multivariable regression techniques were also used to reduce the number of the required input parameters and to conclude that the dimensionless pressure can be a function of the dimensionless revolution per minute and the dimensionless torque. The effect of the dog leg was found so insignificant that it could be neglected without necessarily impacting or compromising the accuracies of the developed models. Data of four wells from the Middle East were used to compare the pressure transducer values with those of the regression models using PTC Mathcad Prime 4.0. The regression models proved accurate enough to estimate the standpipe pressure as shown in Fig. 3.1.</p> <p><strong>Recent Publications (minimum 5)</strong></p> <p>1.
