... heavy oil (saturates, aromatics, resins, and asphaltenes or SARA) were assessed, as well as the effects of organobimetallic liquid catalyst (OLC) on viscosity, density, and interfacial tension (IFT) of heavy oil samples were investigated. The results indicate that the OLC-treated heavy oil exhibited...

... is necessary to develop high-fidelity design tools for sCO 2 power cycles. We measured the density and sound speed of several multi-component mixtures. A temperature-controlled high-pressure test cell was used for the density measurements. Sound speed was measured by resonant frequency detection using...

... to evaluate the rheological behavior of formate-based fluids as a function of temperature and density. An analytical expression was developed to correlate shear stresses with temperature for general drilling fluids and a special case of this expression results in a greatly simplified expression that is valid...

...Ole Harald Utvik; Trygve Rinde; Arne Valle In this paper, results are presented from an experimental comparison between a light hydrocarbon system from the North Sea and a model oil system in pipe flow. The experiments were carried out in order to compare similar fluid systems (density, viscosity...

... and influx to main flow rate ratios ranging from 1/50 to 1/1000. For both the perforation and slot cases, three different completion densities and three different completion phasings are considered. Based on the experimental data, new friction factor correlations for horizontal well with multiple perforation...

...Mamdouh M. Salama, Fellow ASME The current practice for eliminating erosional problems in piping systems is to limit the flow velocity V e to that established by the recommended practice API RP 14E based on an empirical constant ( C -factor) and the fluid mixture density ρ m as follows: V e = C / ρ...

...Hyoung-Jin An; Julius P. Langlinais; S. L. Scott An experimental study was conducted to investigate the effects of density and viscosity on zero net liquid flow (ZNLF) in vertical pipes. Predicting liquid holdup under ZNLF conditions is necessary in several types of petroleum industry operations...
