The current state of the art of several aspects of minerals and petroleum is presented in this volume. It documents the proceedings of the Internationl symposium on Particle Technology and Surface Phenomena in Minerals and Petroleum sponsored by the Fine Particle Society (FPS). This meeting was held in San Diego, California, August 21-25, 1990. The symposium upon which this volume is based was organized in five sessions emphasizing various basic and applied aspects of research on minerals and petroleum technology. Major topics discussed involve surface phenomena in minerals, mineral flotation, characterization of aspaltenes, theoretical aspects of reservoir simulation, porosity, permeability, residual water saturation, hydrocarbon and gas potential in north slope Alaska, polymer/alkaline flooding, surfactant flooding and foam flooding for enhanced oil recovery. This edition includes eighteen selected papers presented in the symposium. These papers are divided in four broad categories: (1) Asphaltene Aggregation and Characterization, (2) Theoretical Aspects and Reservoir Characterization, (3) Colloidal Dispersions in Minerals/Petroleum, and (4) Surface Phenomena and Petroleum Recovery. Several mineral and oil recovery processes using various chemicals with special reference to surface phenomena and particle technology are described in these sections.
