Han-Young Park, Auteur ; Gioia Falcone, Auteur ; Catalin Teodoriu, Auteur |Liquid loading in gas wells is a multiphase flow phenomenon where the liquid content of the well creates back pressure that restricts, and in some cases even stops, the flow of gas from the reservoir. It is estimated that 90% of the producing g[...]

T. A. Adeosun, Auteur ; O.A. Olatunde, Auteur ; J. O. Aderohunmu, Auteur |Calculations of Unsteady-State Gas volumetric flow rate in pipes occur more frequently in the design and operational analysis of natural gas systems. Most of the existing gas pipelines design procedures on Weymouth Equations are based on steady[...]

Jorge Barroso, Auteur ; Juan M. Solis, Auteur ; Javier Ballester, Auteur |This paper presents new results on the characterisation of leak rates in polyethylene gas distribution systems. The work was motivated by the need to update the emission factors used to estimate methane emissions in Spanish networks. There are[...]

Hydrogen production from methane reforming : thermodynamic assessment and autothermal reactor design
C. N. Ávila-Neto, Auteur ; S.C. Dantas, Auteur ; F.A. Silva, Auteur |In this study, a comparative thermodynamic analysis of methane reforming reactions is conducted using an in-house code. Equilibrium compositions are calculated by two distinct methods: (1) evaluation of equilibrium constants and (2) Lagrange mu[...]

Luis F. Ayala H., Auteur ; Doruk Alp, Auteur ; Mohamad Al-Timimy, Auteur |Proper design of separators for surface production facilities is essential in order to maintain the quality and quantity of produced hydrocarbon fluids and avoid major operational problems in downstream equipment. Separators that are not proper[...]

Yueming Cheng, Auteur ; Duane A. McVay, Auteur ; W. John Lee, Auteur |Despite their low production rates, tight gas wells contribute significantly to the Nation's energy supply. Because permeabilities in tight reservoirs can be as low as fractions of a millidarcy, or even in the microdarcy range, drainage areas a[...]
