Many models used to determine pressure and temperature profiles for two-phase flow systems assume that the fluid composition does not change along the wellbore. The aim of this study is to use and combine two-phase flow temperature and pressure profile models and include the effect of composition change for two-phase flow of gas condensate fluid through a wellbore under steady-state conditions. Temperature and pressure profiles obtained from varied composition and constant composition cases are compared for different total mass flow rates. It is found that for the fluid system under consideration, pressure drop for the varied composition case is higher compared to that of constant composition case. However, temperature profiles obtained for both cases were similar to each other within the given pressure and temperature ranges. The increase in total mass flow rate increased the pressure drop. Lower wellhead temperatures were obtained at low total mass flow rates.

Modeling the discharge behavior of a lithium-sulfur battery
Erisen, Nisa; Eroglu, Damla (Wiley, 2020-10-01)
In lithium-sulfur (Li-S) batteries, the discharge performance depends greatly on a number of cell design parameters because of the complex reaction mechanisms in the cathode. Electrolyte-to-sulfur (E/S) ratio and carbon-to-sulfur (C/S) ratio in the cell are key examples of these critical design factors that define the Li-S battery performance. Here, a 1-D electrochemical model is reported to calculate the dependence of the discharge behavior of a Li-S battery on the E/S and C/S ratios. Proposed model descri...
Investigation of Porosity and Permeability Impairment in Sandstones by X-ray Analysis and Simulation
Iscan, A. G.; Kök, Mustafa Verşan; Civan, F. (Informa UK Limited, 2009-01-01)
Both porosity and permeability constitute the major parameters in core analysis. In this study, the variation of these two parameters along a sandstone core sample was investigated during formation damage. A water-based drilling fluid was dynamically circulated through the core sample for three different time intervals of 15 min, 45 min, and 60 min at 100 psi circulation pressure. The core sample was analyzed using x-ray digital radiography by sectional image approach. The differences in the porous media du...
Analytical and Numerical Modeling of CO2 Sequestration in Deep Saline Aquifers
Ozgur, E.; Gumrah, F. (Informa UK Limited, 2010-01-01)
The analytical and numerical modeling of CO2 sequestration in deep saline aquifers having different rock and fluid properties was studied under diffusion and convection mechanisms. In a diffusion dominated system, an aquifer with 100 m thickness was saturated with CO2 after 10,000,000 years. It was much earlier in a convective dominant system. In the diffusion process, the dissolution of CO2 in aquifer increased with porosity increase; however, in a convection dominant process dissolution of CO2 in aquifer ...
Modeling of underground gas storage in a depleted gas field
Gumrah, F; Izgec, O; Gokcesu, U; Bağcı, Ali Suat (Informa UK Limited, 2005-07-15)
It is possible to predict the behavior of fluids in permeable and porous medium under different operating conditions by using reservoir models. Since geological data and reservoir properties can be defined most accurately by reservoir models, it has been accepted as a reliable prediction tool among reservoir engineers. In this study, a gas reservoir has been modeled with IMEX Module of CMG Reservoir Simulator. Rock properties, gas composition and certain production data were entered to the model as input da...
Sensitivity Analysis of Major Drilling Parameters on Cuttings Transport during Drilling Highly-inclined Wells
Ozbayoglu, E. M.; Miska, S. Z.; Takach, N.; Reed, T. (Informa UK Limited, 2009-01-01)
In this study, a layered cuttings transport model is developed for high-angle and horizontal wells, which can be used for incompressible non-Newtonian fluids as well as compressible non-Newtonian fluids (i.e., foams). The effects of major drilling parameters, such as flow rate, rate of penetration, fluid density, viscosity, gas ratio, cuttings size, cuttings density, wellbore inclination and eccentricity of the drillsting on cuttings transport efficiency are analyzed. The major findings from this study are,...
