In search of a statistical probability model for petroleum-resource assessment : a critique of the probabilistic significance of certain concepts and methods used in petroleum-resource assessment : to that end, a probabilistic model is sketched
Bernardo F. Grossling
1975, Circular 724
Exploratory drilling is still in incipient or youthful stages in those areas of the world where the bulk of the potential petroleum resources is yet to be discovered. Methods of assessing resources from projections based on historical production and reserve data are limited to mature areas. For most of the...
Assessment of geothermal resources of the United States, 1975
David L. Williams
Donald Edward White, editor(s)
1975, Circular 726
This assessment of geothermal resources of the United States consists of two major parts: (1) estimates of total heat in the ground to a depth of 10 km and (2) estimates of the part of this total heat that is recoverable with present technology, regardless of price. No attempt has...
A general outline of the water resources of the Toppenish Creek basin, Yakima Indian Reservation, Washington
Dean O. Gregg, Leslie Bostwick Laird
1975, Open-File Report 75-19
Increasing demands for water supplies, plans for irrigating new lands, proposals to divert water from the Yakima River by users downstream from the reservation, and ground-water problems have made an accounting of the overall availability of water very important to water management on the reservation. This report, which broadly outlines...
Formulation and use of practical models for river-quality assessment
Walter G. Hines, D. A. Rickert, S. W. McKenzie, J. P. Bennett
1975, Circular 715-B
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...
Geohydrologic reconnaissance of the upper Potomac River basin
Frank W. Trainer, Frank A. Watkins
1975, Water Supply Paper 2035
The upper Potomac River basin, in the central Appalachian region in Pennsylvania, Maryland, Virginia, and West Virginia, is a humid temperate region of diverse fractured rocks. Three geohydrologic terranes, which underlie large parts of the basin, are described in terms of their aquifer characteristics and of the magnitude and duration...
The Alaskan mineral resource assessment program; background information to accompany folio of geologic and mineral resource maps of the Nabesna Quadrangle, Alaska
Donald H. Richter, N. R. D. Albert, D.F. Barnes, Andrew Griscom, S.P. Marsh, D.A. Singer
1975, Circular 718
The Nabesna quadrangle in south-central Alaska is the first of the l:250,000-scale Alaskan quadrangles to be investigated by an interdisciplinary research team in order to furnish a mineral resource assessment of the State. The assessment of the 17,600-km 2 16,800-mi21 quadrangle is based on field and laboratory investigations of the...
