As worldwide heavy crude oil production increases, pipelines are faced with challenges to transport these higher viscosity fluids. Historically, heavy crude oil has been a challenge for existing commercially available DRAs. As crude oil gravities fall below ∼23 °API, existing DRAs become ineffective. ConocoPhillips Specialty Products Inc. (CSPI) developed a new class of DRAs to address this need. CSPI’s new heavy crude oil DRA technology, ExtremePower™ Flow Improvers, is proven to increase deliveries of produced heavy crude oil to market. In this paper we will discuss the mechanism of drag reduction, how a heavy crude oil DRA works, and two scenarios in which value is created by utilizing the product.

Naphtha and kerosene are mixed with Iraqi heavy crude oil at different concentrations rounded between (3-12) wt.%, in order to reduce viscosity to enhance its followability. This research investigated drag reduction (%Dr) in heavy oil mixtures at different flow rates (2 to 10 m3/hr) in temperature range 20-50C. The experimental results proved that Naphtha offered 40% reduction in pressure drop. The Power law model was adopted in this study to empirically correlate fiction factor (f) and the percentage of drag reduction(%Dr) from experimental data for Reynolds number range (534– 14695) and the concentration range from 3 to12 wt.%.
