As a replacement to the 1970 version, reports of aviation-aerospace educational programs as of March, 1971, for 67 high schools and 6 community colleges of California, are included in this 1972 status report. Following a statement of the rationale and a discussion of the historical development, detailed descriptions are given for most institutions in connection with their student enrollments, course study, and program activities. The educational programs focus on aeronautical science, career education, industrial arts, interdisciplinary approach, military aerospace science, mechanical vocational education, and pilot and preflight. In some programs, the objectives are to prepare for the Federal Aviation Administration certificates. It is pointed out that an advisory committee is essential in carrying out such a statewide program. An overall list of California community colleges offering aviation education programs is also provided. Included in the appendices are excerpts from Education Code, a description of the aviation education survey, a list of high schools for which liability insurance is provided, and sources of information and assistance.

Dual-porosity simulators are ubiquitously used for fractured reservoirs. However, explicit-fracture simulators may be able to increase the accuracy and reliability of simulations for highly fractured reservoirs, because they can directly use descriptions (i.e., lengths, orientations, and apertures) of fractures as obtained from well logs (especially, fmi), out crop analyses, and other geological data. Al- Hussainy et al developed the real gas potential primarily for use in gas-well testing analyses and in single-phase simulators for a single, dry gas. The real gas potential has been used in the current work to develop an explicit fracture reservoir simulator for multi-component, miscible fluids. This simulator considers flow through explicitly defined fractures as well as storage/recharge in/from the surrounding rock matrix. The simulator allows for the use of multiple geologic layers in the reservoir, each of which has independently defined physical and/or flow properties such as thickness, permeability, porosity, diffusivity of the fluids through the rock matrix (important for low-permeability situations), and adsorption isotherms for one of more of the fluid components. Each of the fractures contained in the reservoir also has independently defined physical properties such as height, length, orientation, and aperture. Fluid flow between the layers of the geologic strata is via user-defined multi-layer fractures which extend through two or more layers. Such multi-layer fracture networks can be easily generated through the use of such codes as NETL’s FRACGEN, the output of which can be used directly with the flow simulator being reported on here. As a result of the explicit handling of fractures as well as the use of the potential formulation, simulation of multi-layer reservoirs containing tens of thousands of fractures can be performed in shorter times than those required by finite element codes. ------------------ (1)EG&G (2)U.S. Department of Energy
