ABSTRACT
The motion of a multifluid flow is of interest in the oil and gas industry. The flow characteristics aid or impede production rate. This study analyses two phase fluid flow characteristics consisting of crude oil and natural gas, in straight pipes of the same internal diameter, using homogenous model. Flow values were obtained from a Niger Delta flow station and predetermined experimental flow equations were used to determine the pressure drop in order to comprehend the flow characteristics in the pipeline. An average total pressure loss (∆PT) of 0.075 MPa was obtained in the laminar flow category at 0.006228 MPa/m and an average total pressure (∆PT) of 27.896 MPa in turbulent flow category at 2.325 MPa/m in a pipe length of 12 metres. Graphs were plotted to show the influence of the calculated flow parameters on the fluid flow. The graphs aided in depicting the flow regimes in the pipeline. These are universally dominant parameters in the oil and gas industry as they significantly impact on the transportation of crude oil from oil wells or reservoirs to the process plants. These results may be used as a baseline and guide to compare realistic measurements in similar flows.
