This report summarizes the activities for 1987. Much of the Division`s research deals with the physical and chemical properties and processes in the Earth`s crust, from the partially saturated, low-temperature near-surface environment to the high-temperature environments characteristic of regions where magmatic-hydrothermal processes are active. Strengths in laboratory and field instrumentation, numerical modeling, and in situ measurement allow study of the transport of mass and heat through geologic media{emdash}studies that now include the appropriate chemical reactions and the hydraulic-mechanical complexities of fractured rock systems. Related and parallel laboratory and field investigations address the effects of temperature, pressure, stresses, pore fluids, and fractures on the elastic and electrical properties of rock masses. These studies are concerned with rock behavior in the brittle and ductile crustal regimes, and they drive the development of improved geomechanical and geophysical tools and techniques for mapping and characterizing heterogeneity in the subsurface. The Division has increased its emphasis on the application of fluid transport modeling and subsurface imaging methods to problems related to discovery and recovery of petroleum. Each of the 166 individual reports is presented in a publication format and contains significant new information.
