| dc.description.abstract | A calculation method for predicting pressure profiles along the wellbore based on easily obtainable wellhead parameter has been the preferred method. But, the predictive capability of the existing correlations is a thing of concern. This is due to the inability of the existing models and correlations to account for the presence of the sand particles in the flow stream; also the requirement for the well to be shut-in in order to acquire the needed parameters is counter productive. These inadequacies were corrected in the proposed model. Results showed that the average pressure drop in the multiphase fluid flow using the proposed model is higher than the pressure drops determined using existing models and correlations. The effects of the fluid density, viscosity and velocity on the sand particles lifting were also investigated and results showed that the sand particles suspension and lifting were improved by higher fluid velocity and density and lower fluid viscosity (i.e. higher Reynolds number). Validation of the proposed model with field data showed that the model predicts the field BHP data better than any of the existing models and correlations, based on the Average Absolute Deviation (AAD) value of 6.53 returned by the proposed model compared to AAD value of between 13.56 and 24.67 returned by the existing models and correlations. | en_US |
