Available in PDF, EPUB and Kindle. Book excerpt: Within the last 10 years the world has come to a point where the easily explorable oil deposits have now been found, and it is anticipated that such deposits will be depleted by the beginning of the Twenty-first Century. However, the increasing demand of man kind for energy has caused technologists to look into ways of find ing new sources or to reevaluat:e unconventional sources which, in the past, have not been economical. In this respect, heavy crude and tar sand oils are becoming important in fulfilling the world's energy requirements. What are heavy crude and tar sand oils? There is still some confusion as to their definitions, inasmuch as they vary among organizations and countries. In an effort to set agreed meanings, UNITAR, in a meeting in February 1982 in Venezuela, proposed the following definitions (see also Table 1): 1. Heavy crude oil and tar sand oil are petroleum or petroleum like liquids or semi-solids naturally occurring in porous media. The porous media are sands, sandstone, and carbonate rocks. 2. These oils will be characterized by viscosity and density. Viscosity will be used to define heavy crude oil and tar sand oil, and density (oAPI) will be used when viscosity measurements are not available. 3. Heavy crude oil has a gas-free viscosity of 100-10000 mPa.s (cp) 3 o at reservoir temperatures, or a density of 943 kg/m (20 API) 3 o o to 1000 kg/m (10 API) at 15.6 C and at atmospheric oressure.

Available in PDF, EPUB and Kindle. Book excerpt: This book aims at presenting, describing, and summarizing the latest advances in polymer flooding regarding the chemical synthesis of the EOR agents and the numerical simulation of compositional models in porous media, including a description of the possible applications of nanotechnology acting as a booster of traditional chemical EOR processes. A large part of the world economy depends nowadays on non-renewable energy sources, most of them of fossil origin. Though the search for and the development of newer, greener, and more sustainable sources have been going on for the last decades, humanity is still fossil-fuel dependent. Primary and secondary oil recovery techniques merely produce up to a half of the Original Oil In Place. Enhanced Oil Recovery (EOR) processes are aimed at further increasing this value. Among these, chemical EOR techniques (including polymer flooding) present a great potential in low- and medium-viscosity oilfields. • Describes recent advances in chemical enhanced oil recovery. • Contains detailed description of polymer flooding and nanotechnology as promising boosting tools for EOR. • Includes both experimental and theoretical studies. About the Authors Patrizio Raffa is Assistant Professor at the University of Groningen.

Download or read book Enhanced Heavy Oil Recovery Using CO2 Huff N Puff Process written by Xiang Zhou and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: CO2 based enhanced oil recovery methods, such as continuous CO2 injection, intermittent CO2 injection, water-alternating CO2 injection, and CO2 huff 'n' puff, are successfully implemented in heavy oil reservoirs. Among them, the CO2 huff 'n' puff method has been proved as an applicable recovery method. Although many previous researches were conducted on the CO2 huff 'n' puff process applied in heavy oil reservoirs, some technical issues are still not investigated, such as non-equilibrium phase behaviors of foamy oil flow, CO2 diffusion into heavy oil, and the production performance in CO2 huff 'n' puff process coupled with non-equilibrium phase behaviors and CO2 diffusion. Therefore, this study aims at addressing the following major topics. Non-equilibrium phase behaviors of foamy oil flow. In order to investigate the foamy oil flow behavior in the primary production process, experimental studies on nonequilibrium phase behaviors of heavy oil-methane system are implemented in a pressure/volume/temperature cell with different pressure decline methods. The experimental results indicate that, with pressure decline rate increases, the pseudo-bubblepoint pressure decreases, leading to longer pressure duration of foamy oil, so that the foamy oil stability becomes stronger under higher pressure depletion rate. To study foamy oil stability in the production stage of the CO2 huff 'n' puff process, the non-equilibrium phase behaviors are investigated using the heavy oil-CO2 system. The same experimental methods are applied with that in the heavy oil-methane system, but the gas transfers rates (solution gas transfers to dispersed gas, dispersed gas transfers to free gas) in heavy oil- CO2 system are much higher than that observed in the heavy oil-methane system. A dynamic reaction rate model is developed to match the foamy oil stability using heavy oil- CO2 system, and high agreements are achieved. The reaction rate constants (k1 and k2) among different gas phases are determined through the history match. The performance of foamy oil flow, in the production stage of the CO2 huff 'n' puff process, highly relates to the amount of CO2 dissolves into heavy oil during the soaking stage. To understand the CO2 diffusion process in the heavy oil, CO2 diffusion coefficient is measured in both bulk phase (high pressure cell) and porous media (real reservoir core). The CO2 diffusion coefficient determination process mainly includes: (1) experimental study is conducted to measure the pressures in the diffusion process using the pressure decay method; (2) mathematical modeling study is carried out to calculate the CO2 diffusion coefficients using the history match method. Based on the understandings of the non-equilibrium phase behaviors and CO2 diffusion, the heavy oil production performance in CO2 huff 'n' puff process coupled with non-equilibrium phase behavior and CO2 diffusion is investigated. Six CO2 huff 'n' puff experiments are carried out using long cores (60 cm). The main affect parameters are studied, including pressure depletion rates (0.5, 1, 4, and 16 kPa/min), soaking time (5, 10, and 20 hours) and cycle numbers. Via experimental study, an equation which indicates the relationship of the cumulative oil and gas production in each cycle and each test is gained with high agreement. The experimental results indicate that the CO2 huff 'n' puff process can be an efficient approach to enhance heavy oil production with a recovery factor of 38.02%. The optimized pressure depletion rates, soaking time and cycle numbers are 1 kPa/min, 5 hours and 3 cycles, respectively, and the optimization parameters are upscaled for field application using scaling criteria.

Book excerpt: An in-depth study of the fundamental aspects of enhanced oil recovery (EOR), this book brings together detailed analyses of proven techniques. It begins with the current theories of the origin of oil and ends with a treatise on waterflooding which is the basis of the majority of EOR processes. Two and three-phase relative permeability relationships are discussed since they form the basis for fluid flow processes in porous media. The advent of EOR has increased the need for a better understanding of three-phase flow because this has become an integral part of carbon dioxide and steam injection, yet is an area of experimental study that has been seriously neglected. The book gives a complete review and theoretical analysis of two- and three-phase fluid flow, plus a basic introduction to single-well pressure transient testing which is essential to the evaluation of volume, intrinsic reservoir pressure, reservoir discontinuities, in situ permeability and many other data required for complete reservoir evaluation. A discussion of oilfield waters is followed closely by the chemical and physical properties of employing various current EOR techniques.The book will interest a wide range of readers. Teachers of petroleum engineering will find it a ready reference to basic requirements for implementation of various EOR processes. Petroleum engineering researchers can use it to review the current state-of-the-art of the basic premise of EOR and find in it the necessary background analyses for projection of future research. The field-oriented, practical petroleum engineer will discover it to be a reliable reference to criteria for pre-EOR reservoir analysis.

Download or read book Polymer Improved Oil Recovery written by K.S. Sorbie and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of oil in the world economy cannot be overstated, and methods for recovering oil will be the subject of much scientific and engineering research for many years to come. Even after the application of primary depletion and secondary recovery processes (usually waterflooding), much oil usually remains in a reservoir, and indeed in some heterogeneous reservoir systems as much as 70% of the original oil may remain. Thus, there is an enormous incentive for the development of improved or enhanced methods of oil recovery, aimed at recovering some portion of this remainil)g oil. The techniques used range from 'improved' secondary flooding methods (including polymer and certain gas injection processes) through to 'enhanced' or 'tertiary' methods such as chemical (surfactant, caustic, foam), gas miscible (carbon dioxide, gas reinjection) and thermal (steam soak and drive, in-situ combustion). The distinction between the classification ofthe methods usually refers to the target oil that the process seeks to recover. That is, in 'improved' recovery we are usually aiming to increase the oil sweep efficiency, whereas in 'tertiary' recovery we aim to mobilise and recover residual or capillary trapped oil. There are a few books and collections of articles which give general overviews of improved and enhanced oil recovery methods. However, for each recovery method, there is such a wide range of interconnected issues concerning the chemistry, physics and fluid mechanics of flow in porous media, that rarely are these adequately reviewed.
