Book excerpt: Heavy oils, extra-heavy oils and tar sands are major players for the future of energy.They represent a massive world resource, at least the size of conventional oils. They are found all over the world but Canada and Venezuela together account, by themselves, for more than half of world deposits. They share the same origin as the lighter conventional oils, but their geological fate drove them into thick, viscous tar-like crude oils. Most of them result from alteration processes mediated by microbial degradation. They are characterized by a low content of lighter cuts and a high content of impurities such as sulfur and nitrogen compounds and metals ; so, their production is difficult and deployment of specific processes is required in order to enhance their transportability and to upgrade them into valuable products meeting market needs, and honouring environmental requirements.Although these resources are increasingly becoming commercially producible, less than 1% of total heavy crude oil deposits worldwide are under active development. The voluntarily wide scope of this volume encompasses geology, production, transportation, upgrading, economics and environmental issues of heavy oils. It does not pretend to be exhaustive, but to provide an authoritative view of this very important energy resource.

This book was released on 2015 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rheological properties of heavy oil and bitumen depend on factors such as temperature, pressure, diluent type and diluent composition, as well as sample shear and thermal histories and shear conditions during measurements. Each of these factors can affect the value of apparent viscosity significantly. Uncertainties in the available literature data arise when one or more of these factors have not been considered and have not been reported. Heavy oil and bitumen exhibit non-Newtonian rheological behaviors at lower temperatures. Methods for detecting and quantifying non-Newtonian behaviors are developed, presented and explored in this work using a well-characterized heavy crude oil. The methods and results presented for Maya crude oil provide a reliable database for rheological model development and evaluation, and a template for assessing the rheological behavior of other heavy crude oils. The thixotropic behavior of Maya crude oil was explored systematically using a stress-controlled rheometer. Thixotropy affects the efficiency and length scale of mixing during blending operations, and flow behaviors in pipes and pipelines following flow disruption where it affects the pressure required to reinitiate flow. Maya crude oil is shown to be a shear thinning fluid below 313 K. The thixotropic behaviors are explored using transient stress techniques (hysteresis loops, step-wise change in shear rate, start-up experiments). The magnitude of the thixotropy effect is larger at lower temperatures. Relationships are identified between rest times and other thixotropic parameters such as hysteresis loop area and stress decay in start-up experiments. Stress growth, which occurs as a result of a step-down in shear rate, is shown to correlate with temperature. The interrelation between rheological behavior of Maya crude oil and its phase behavior is discussed. The effect of pressure on the non-Newtonian rheological properties of Maya crude oil is also investigated over broad ranges of temperature from (258 to 333) K and at pressures up to 150 bar. At fixed temperature, the magnitude of the non-Newtonian behaviors of Maya crude oil appears to increase with increasing the pressure and shear thinning is shown to persist to higher pressures below 313 K. Boundaries of the non-Newtonian region with respect to temperature, pressure and viscosity are identified and discussed. The thixotropic behavior of Maya crude oil is also shown to persist at higher pressure and the recovery of the moduli at rest appears to be faster at elevated pressures than at atmospheric pressure. Understanding the rheological properties of mixtures of heavy oil or bitumen and diluents, specifically at low temperatures, is key in designing different processes employed in production or transportation of these resources reliably and efficiently. The effect of diluents (n-heptane, toluene and toluene + butanone (50/50 vol. %)) on the non-Newtonian behavior of Maya crude oil including shear thinning and thixotropy at temperatures from (258 to 333) K are discussed. Toluene + butanone (50/50 vol.%) addition to Maya crude oil induces the greatest reduction in shear thinning behavior irrespective of temperature. Thixotropic properties of mixtures of Maya crude oil and diluent were studied through start-up experiments. It was shown that toluene + butanone (50/50 vol.%) is the best diluent in moderating the thixotropic effect, while n-heptane showed the most pronounced thixotropic effect. It was shown that toluene + butanone (50/50 vol. %) is more promising in decreasing oil viscosity in comparison to two other diluents tested. Less of this diluent is required to decrease the viscosity to a certain value, which confirms its potential application to be used in the industry as a diluent.

Available in PDF, EPUB and Kindle. Book excerpt: Reservoir characterization is the model that characterizes reservoirs based on their ability to store and produce hydrocarbons. Reservoir modeling is the process of creating a three-dimensional representation of a given reservoir based on its petrophysical, geological, and geophysical properties. Reservoir engineering is the formulation of development and production plans that will result in maximum recovery for a given set of economic, environmental, and technical constraints. It is not a one-time activity but needs continual updating throughout the production life of a reservoir. Reservoir management is often defined as the allocation of resources to optimize hydrocarbon recovery from a reservoir while minimizing capital investments and operating expenses. The oil and gas industry is divided into upstream and downstream sectors. In general, the upstream sector involves activities carried out at a reservoir, while the downstream sector involves all petroleum processing activities carried out in a refinery. Petroleum processing engineering involves all downstream crude oil processing operations, from crude oil as the feedstock to final products such as gasoline, kerosene, diesel, gas oil, and lubricating oil. Petroleum processing technology continues to develop in consideration of all types of sustainability-related challenges. This book provides a comprehensive overview of the oil and gas industry, presenting the most recent research in the field.

Available in PDF, EPUB and Kindle. Book excerpt: The rheological study of heavy crude oil is important in the field of petroleum engineering. The rheological properties of heavy oil (e.g., shear stress, shear rate, viscosity, etc.) depend on several factors including temperature, pressure, surface tension, diluent type and diluent composition, pH, shear stress and thermal histories, memory, and shear conditions during the analysis. The investigation of the rheology of heavy crude oil flow is a critical issue for both upstream and downstream operations. The objective of this study is to perform an investigation on the rheological properties of heavy crude oil to show the effect of shear rate, temperature, and pressure on the viscosity and the shear stress. The aim of this work was to broaden current knowledge of the rheological behavior and flow characterization of heavy crude oil. This paper takes a new look at the shear stress-strain relationship by considering the memory effect along with temperature effect on the shear rate. It is considered that the viscosity of the heavy crude oil is a function of pressure, temperature, and shear rate. As the heavy crude oil is considered as a Bingham fluid, Bingham model is employed here for the analysis. The experimental data from previous studies are used to complete the analysis. To develop the model, a modified Darcy's law that employs the effect of memory on the Bingham model is considered. The effect of temperature has been incorporated by the Arrhenius equation for the development of a new model to study the heavy crude oil rheological behaviors. The relationship between shear stress and viscosity has been shown at different fractional derivative order and time. The validation and the simulation of the model are performed by using the experimental and the field data from the literature. The numerical simulation of this model is conducted by using the MATLAB simulation software. From the sensitivity analysis, it is found that the temperature has the highest impact on the viscosity over the pressure and the shear rate. On the other hand, the pressure shows a strong effect on the shear stress-shear rate relationship over the temperature. In the model analysis, it is found that the fluid memory affects in the Bingham model due to nonlinear behavior of heavy crude oil. The shear stress increases with decreasing viscosity at different fractional derivative order and time. The change in shear stress is high at large fractional derivative. The range of fractional derivative order is from 0.2 to 0.8. When fractional derivative order,

Available in PDF, EPUB and Kindle. Book excerpt: This and its companion Volumes 4 and 5 document the proceedings of the 5th International Symposium on Surfactants in Solution held in Bordeaux, France, July 9-13, 1984. This symposium was the continuation of the series of symposia initiated in 1976 in Albany, New Vork under the title ""icellization, Solubilization and "icroemulsions". The next two symposia were labelled "Solution Chemistry of Surfactants" and "Solution Behavior of Surfactants: Theoretical and Applied Aspects" held in Knoxville, TN in 1978 and Potsdam, N. V. in 1980, respectively. In 19B2 at the time of the 4th Symposium in this series, it became amply evident that there was a definite need to have more a generic title to describe these biennial events, and after much deliberation it was decided that an appropriate title would be "Surfactants in Solution" as both the aggregation and adsorption aspects of surfactants were addressed. So the 4th Symposium was held in 1982 in Lund, Sweden, under this new rubric, and it was decided to continue these symposia in the future under this appellation. Naturally, the Bordeaux Symposium was dubbed as the 5th International Symposium on Surfactants in Solution, and our logo became SIS which is very apropos and appealing. It was in Bordeaux that the decision was made to hold the 6th SIS Symposium in New Delhi and it is scheduled for August 18-22, 1986 in the capital of India.

This book was released on 2011 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the combination of an increase in world energy demand and the decline of conventional oils, heavy crude oils have been presented as a relevant hydrocarbons resource for use in the future. Hydrocarbon resources are very important given that they account for approximately 65% of the world's overall energy resources. Currently, there are three general approaches for transportation of heavy and extra heavy oil: viscosity reduction, drag minimization and in-situ oil upgrading. This book introduces Another promising pipeline technique is the transport of viscous crudes as concentrated oil-in-water (O/W) emulsions.

This book was released on 2020-09-23 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses conventional and new predictive methodologies for estimating thermophysical properties of heavy petroleum fluids. For the unidentifiable fractions forming the fluids, chemical structures are calculated so that property estimation methods for mixtures of identifiable components are now available for such fractions. Chemical and multiphase equilibriums are of utmost importance; hence, the most significant ones involving heavy petroleum fluids are determined and illustrated using advanced equations of state such as sPC-SAFT and EoS/GE. The included phase equilibriums are phase envelopes of reservoir fluids, asymmetric mixtures between light solvents and bitumen including the presence of water and asphaltenes, among others. Besides, heavy petroleum fluids are analyzed from the Newtonian and non-Newtonian viewpoints, exploring their complex rheological behavior. Finally, complemented by online an Excel program for the thermodynamic characterization of unidentifiable petroleum fractions, this book is a useful resource for engineers and researchers in the petroleum industry and is also of interest to students studying chemical and petroleum engineering.
