Edison's Geothermal Program - 1980 Update

Description: In 1975, negotiations were initiated with two major resource developers toward initiating power plant projects at three of the Imperial Valley resource areas, Brawley, Salton Sea and Heber. The projects at Brawley and Salton Sea are substantially different from that at Heber in objective, size and design. The reasons for these differences are related to the different nature of the geothermal brines and to different operating philosophies of the resource developers involved. The projects at Braw… more

Sensitivity of geothermal reservoir behavior to relative permeability parameters

Description: Three problems are considered: (1) the sensitivity of the total kinematic viscosity, ..nu..{sub t}, and the flowing enthalpy, h{sub f}, to variations in the relative permeability functions; (2) the determination of ..nu..{sub t} and h/sub f/ from well-test data, following which a method is suggested to use these results together with theoretical plots of the relative permeability functions versus h{sub f} to deduce the general shape of the relative permeability functions; and (3) the effect of … more

Numerical simulation of the natural evolution of vapor-dominated hydrothermal systems

Description: Simulation of the transient evolution of a cold hydrothermal system into a steady-state partially vapor-dominated system is described. Here the effects of salts and gases were neglected and it was assumed that rock properties are time independent and homogeneous within each part of the system. Despite these simplifications it is believed that the model demonstrates the essential features of a natural hydrothermal convection system. (MHR)

Modified Weibull theory and stress-concentration factors of polycrystalline graphite

Description: Stress concentration factors (SCF) due to geometric discontinuities in graphite specimens are observed to be much less than the theoretical SCF in an elastic material. In fact, the experimental SCF is always less than two and sometimes even less than one. A four parameter Weibull theory which recognizes the grain size effect is found to give an adequate explanation of the above observed discrepancies.

Oil/gas supply modeling considerations in long-range forecasting. [Use of LEAP: Long-Range Energy Analysis Program]

Description: Oil- and gas-supply modeling may not only generate forecasts on a stand-alone basis, but may provide input data and assumptions to large-scale, long-range integrated energy economy models. In such a framework, parameters that may not have seemed especially crucial in the stand-alone formulation may be found to have an unexpectedly great influence on the results. Additionally, it may become necessary to incorporate considerations that are usually omitted from conventional oil- and gas-supply mod… more
