CFD simulation of methane flow through an orifice plate
Abstract: In this paper the effects of errors in the flow rate and discharge coefficient when Methane (CH4) flow through orifice plates with flange tapping has been investigated by the Computational Fluid Dynamics (CFD). The location of vena- contracta was also estimated from CFD simulations. Outcomes of the CFD simulations are in terms of profiles of pressure and velocity. In this study a numerical investigation of the flow characteristics behavior caused …

Numerical study of the impact of surfactant/polymer flooding on different reservoir wetting phases.
Abstract: Production of oil and gas by primary drive mechanism has always remained unsatisfactory since a greater percentage of the oil remains in the reservoir. Across the industry and academia various enhanced oil recovery interventions are been sought after to help recover more and more hydrocarbons from the reservoir. A simulation study is conducted using the UTCHEM simulator to help understand the mechanism that affect the various wetting characteristics of the …

Thermodynamic modelling of the effects of high temperatures on brine fluid density
Abstract: Current trends in oil discoveries points to deep water zones characterized by temperatures ranging from 150oC to 350oC which needs good prediction of the fracture pressure and pore pressure hence imperative to continually understand temperature-density relationships of the fluids which are pumped downhole for well control. This paper seeks to propose a new, cost effective and easier method of estimating the reduction in density of brine completion fluid as it …

Solutions to Problems Faced in Well Log Analysis in fractured metamorphic Reservoir Systems Due To Multiple Porosities and Lithology’s
Abstract: Metamorphic rocks are the most bottomless non-terrigenous sedimentary rock and are made essentially out of transformative minerals. Most metamorphic rocks shape from calcareous stores that collect in marine conditions running from salt marshes to reefs to profound sea bowls. Unmistakable and one of a kind parts of transformative rocks are their dominatingly intrabasinal starting point, their essential reliance on natural exercises for their constituents and their powerlessness to change by …

Performance of Equation-of-State for Hydrocarbon Dew Point Control in Gas Flow-line in a Nigerian Field
Abstract: Associated gas in a flow-line in a Nigerian field was suspected to be accountable for unaccounted-for gas in the flow-station. Gas molecular compositions of Low Pressure suction gas and Injection Discharge gas for operating conditions of pressure and temperature from the field were analysed by the use of Soave-Redlich Kwong and Peng-Robinson Equations of State with PVTp thermodynamic software. The phase envelope predicted the Hydrocarbon dew point(s) observable from the …
