Available in PDF, EPUB and Kindle. Book excerpt: Gas viscosity is one of the gas properties that is vital to petroleum engineering. Its role in the oil and gas production and transportation is indicated by its contribution in the resistance to the flow of a fluid both in porous media and pipes. Although viscosity of some pure components such as methane, ethane, propane, butane, nitrogen, carbon dioxide and binary mixtures of these components at low-intermediate pressure and temperature had been studied intensively and been understood thoroughly, very few investigations were performed on viscosity of naturally occurring gases, especially gas condensates at low-intermediate pressure and temperature, even fewer lab data were published. No gas viscosity data at high pressures and high temperatures (HPHT) is available. Therefore this gap in the oil industry still needs to be filled. Gas viscosity at HPHT becomes crucial to modern oil industry as exploration and production move to deep formation or deep water where HPHT is not uncommon. Therefore, any hydrocarbon encountered there is more gas than oil due to the chemical reaction causing oil to transfer to gas as temperature increases. We need gas viscosity to optimize production rate for production system, estimate reserves, model gas injection, design drilling fluid, and monitor gas movement in well control. Current gas viscosity correlations are derived using measured data at low-moderate pressures and temperatures, and then extrapolated to HPHT. No measured gas viscosities at HPHT are available so far. The validities of these correlations for gas viscosity at HPHT are doubted due to lack of experimental data. In this study, four types of viscometers are evaluated and their advantages and disadvantages are listed. The falling body viscometer is used to measure gas viscosity at a pressure range of 3000 to 25000 psi and a temperature range of 100 to 415 °F. Nitrogen viscosity is measured to take into account of the fact that the concentration of nonhydrocarbons increase drastically in HPHT reservoir. More nitrogen is found as we move to HPHT reservoirs. High concentration nitrogen in natural gas affects not only the heat value of natural gas, but also gas viscosity which is critical to petroleum engineering. Nitrogen is also one of common inject gases in gas injection projects, thus an accurate estimation of its viscosity is vital to analyze reservoir performance. Then methane viscosity is measured to honor that hydrocarbon in HPHT which is almost pure methane. From our experiments, we found that while the Lee-Gonzalez-Eakin correlation estimates gas viscosity at a low-moderate pressure and temperature accurately, it cannot give good match of gas viscosity at HPHT. Apparently, current correlations need to be modified to predict gas viscosity at HPHT. New correlations constructed for HPHT conditions based on our experiment data give more confidence on gas viscosity.

This book was released on 2012-12-06 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 38 (thesis year 1993) a total of 13,787 thesis titles from 22 Canadian and 164 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 38 reports theses submitted in 1993, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Modeling the performance of high-pressure, high-temperature (HPHT) natural gas reservoirs requires the understanding of gas behavior at such conditions. In particular, gas viscosity is an important fluid property that directly affects fluid flow through porous media and along production flowlines. Accurate measurements of gas viscosity at HPHT conditions are both extremely difficult and expensive. Unfortunately, the correlations available today do not have a sufficiently broad range of applicability in terms of pressure and temperature since no measured gas viscosities at HPHT are currently available. Thus the correlation accuracy may be doubtful for the prediction of gas viscosity at HPHT conditions. An oscillating-piston viscometer was used to measure the viscosity of mixtures of nitrogen and methane, and mixtures of CO2 and methane at a pressure range of 5,000 to 25,000 psi, and a temperature range of 100 to 360 degrees F. The viscosity of mixtures of nitrogen and methane, and mixtures of CO2 and methane measured to take into account of the fact that the concentration of non-hydrocarbons increase significantly in HPHT reservoir. The recorded measured data were then used to evaluate the reliability of the most commonly used correlations in the petroleum industry. Measured gas viscosity data at HPHT conditions suggest that the most common gas viscosity correlations return up to 9% relative error in gas recovery factor, which translates into a significant error in estimating the ultimate recovery for large HPHT natural gas reservoirs. Thus, the current gas viscosity correlations need to be adjusted to estimate gas viscosity at HPHT conditions. New gas viscosity correlations constructed for HPHT conditions developed based upon our experiment data provide more confidence on gas viscosity. A rolling ball viscometer was also used to assess its capability to measure gas viscosity. Using gas instead of liquid to calibrate a rolling ball viscometer over the entire pressure and temperature range of interest appears to be satisfactory. Optimizing tube inclination angle and ball/tube diameter ratio prevents turbulent flow effects around the ball, thus enhancing the accuracy of the measurement. The proposed calibration method was then verified with pure CO2 at a pressure range of 4,000 to 8,000 psi, and a temperature range of 98 to 240° F. Consequently, rolling ball viscometer was introduced as a good candidate to measure the gas viscosity; however it has not been tested at HPHT conditions yet.

Available in PDF, EPUB and Kindle. Book excerpt: Estimation of viscosities of naturally occurring petroleum gases provides the information needed to accurately work out reservoir-engineering problems. Existing models for viscosity prediction are limited by data, especially at high pressures and high temperatures. Studies show that the predicted viscosities of natural gases using the current correlation equations are about 15 % higher than the corresponding measured viscosities at high pressures and high temperatures. This project proposes to develop a viscosity prediction model for natural gases at high pressures and high temperatures. The project shows that commercial gas viscosity measurement devices currently available suffer from a variety of problems and do not give reliable or repeatable results. However, at the extremely high pressures encountered in high pressure and high temperature reservoirs, the natural gases consist mainly of methane as the hydrocarbon constituent and some non-hydrocarbon impurities. Available viscosity values of methane were used in the development of a correlation for predicting the viscosities of naturally occurring petroleum gases at high pressures and high temperatures. In the absence of measurements, this correlation can be used with some confidence.
