This book is divided in two sections. Several chapters in the first section provide a state-of-the-art review of various carbon sinks for CO2 sequestration such as soil and oceans. Other chapters discuss the carbon sequestration achieved by storage in kerogen nanopores, CO2 miscible flooding and generation of energy efficient solvents for postcombustion CO2 capture. The chapters in the second section focus on monitoring and tracking of CO2 migration in various types of storage sites, as well as important physical parameters relevant to sequestration. Both researchers and students should find the material useful in their work.

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.

Miscible carbon dioxide flooding is an effective EOR technique for the displacement of reservoir oil after primary and secondary oil recovery methods have been exhausted. Miscibility is achieved either through a first-contact or multi-contact process. The dynamic multi-contact process involves exchange of components between oil and solvent gas through vaporizing and/or condensing drives ultimately resulting in lower interfacial tension and oil viscosity thereby improving oil displacement. By definition the minimum miscibility pressure (MMP) is the pressure at which miscibility is achieved; operating below MMP will drastically reduce hydrocarbon recovery while operating above MMP will add additional costs to the project with little or no additional recover. The main focus of this study is to design and implement a Rising Bubble Apparatus (RBA) for system MMP identification. The various scenarios to be tested include dead Oil C-pure CO2, live Oil C-impure CO2, and dead Oil C-impure CO2. Vanishing interfacial tension (VIT) results are also analyzed and compared to RBA results; recommendation can then be made to identify the most consistent and accurate method of MMP estimation. When applying the VIT method, the MMP's for the three cases were determined to be 10.7 MPa for the dead Oil C-pure CO2 system, 12.3 MPa for the live Oil C-impure CO2 system, and 21.2 MPa for the dead Oil C-impure CO2 system. When applying the RBA method, the MMP's were determined to be 12.0 MPa for the dead Oil C-pure CO2, 12.5 MPa for the live Oil C-impure CO2 system, and 25.0 MPa for the dead Oil C-impure CO2 system. The two methods yield similar results, however values of MMP from RBA experiments tend to be slightly higher.

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.
