Natural Resource Pricing And Economic Development, Vaman Rao
Natural Resource Pricing And Economic Development, Vaman Rao
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
In a competitive equilibrium the price of a natural resource will be increasing at a rate equal to the social time preference rate, but in a monopoly market, the price will be increasing at less than social time preference rate. If the producer countries utilise their monopoly of production and sale of a natural resource for the purpose of developing their economies, the price of the natural resource will be growing at the rate at which the producer countries' economies are growing, whether or not the sales proceeds are used to finance their investment programmes, fully or partly.
Optimum Control Of Heating, Ventilating And Air Conditioning Systems, Terry R. Weaver
Optimum Control Of Heating, Ventilating And Air Conditioning Systems, Terry R. Weaver
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The control of HVAC systems has traditionally been performed by relatively simple field hardware. The industry appears, however, to be ready for the use of more sophisticated measures. The paper presents several approaches to the conservation of energy in this area with the use of closed-loop computer control and optimization.
Creating The Electric Energy Economy, L. G. Hauser
Creating The Electric Energy Economy, L. G. Hauser
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
My remarks will be directed to four points:
First, that energy is the life blood of our economy, and that its use or conservation is far from a simple matter of personal habits of waste or frugality. In other words, the vital role energy plays in the production of goods and services should be distinguished from its use in their consumption.
Second, that our excessive dependence on our two scarcest energy resources -- oil and natural gas -- is the core of the energy problem, both U.S. and worldwide.
Third, that limiting our time horizon to this winter, next summer, …
Centralized Solar Wind Home Heating, Russell Peterson, Duane Cromack
Centralized Solar Wind Home Heating, Russell Peterson, Duane Cromack
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
In the immediacy of national goals for energy independence, the need emerges to use dialectic methods to diminish the energy consumptive characteristics of the typical home.
At the cutting edge of resourceful progress are the residential developments which embrace alternative and conservative energy techniques. In conjunction with such a planned, low impact community, this paper proposes a cluster-centralized system which utilizes wind energy in combination with solar thermal energy for space and domestic water heating.
A description of the random solar-wind resource embodies a matching problem that in turn reveals the benefits of the combined mode of energy collection. Though …
Energy And Transportation Policy, James S. Sagner
Energy And Transportation Policy, James S. Sagner
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Energy shortages of recent years suggest a re-examination of national transportation policy. The lack of a coordinated approach to the solution of urban cogestion inhibits potential short-run responses to gasoline shortfalls. Longer-range policy, particularly in the context of severe financial constraints, must be carefully integrated with demonstrated patterns of urban travel and population and employment densities. Given these considerations, metropolitan areas now planning or constructing rapid rail facilities may be selecting inappropriate responses to the problem of urban access.
Energy, Environment And Incremental Decision Making, Jeff V. Conopask, Robert R. Reynolds Jr.
Energy, Environment And Incremental Decision Making, Jeff V. Conopask, Robert R. Reynolds Jr.
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
During the late 1960's and early 70's a variety of environmental/energy oriented legislation was enacted by the Congress. The most important of these acts, the National Environmental Protection Act (NEPA), required that environmental impact statements be filed when various private and public activities have a potential for impacting man and his environment. (17) Impact statement requirements go beyond the currently practiced cost/benefit analysis, which is often just a production (direct) impact assessment. Heretofore, indirect or second round economic and social effects of consequence affecting other national goals were seldom counted.
The Design And Performance Of A Distributed Flow Water-Cooled Solar Collector, Donald L. Spencer, Theodore F. Smith, Herbert R. Flindt
The Design And Performance Of A Distributed Flow Water-Cooled Solar Collector, Donald L. Spencer, Theodore F. Smith, Herbert R. Flindt
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Design of a flat plate collector which reduces the temperature differential between the absorber plate and the fluid is described. The reduced temperature differences are shown to yield increase collector performance. Flow characteristics of the collector are examined. Collector thermal performance is illustrated for typical operating and environmental conditions. A cost analysis is presented to demonstrate that material and assembly costs are substantially lower than for any collector presently on the market.

Direct Ac Generation From Solar Cell Arrays, Fernando L. Alvarado, Adel H. Eltimsahy
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Results of the investigation of the performance of solar cells when directly coupled to a conventional three-phase power network are presented. This approach dissociates the electricity production problem from the electric energy storage problem. Extensive studies of the required power inverter are performed. Preliminary simulation results indicate that ac power outputs of better than 90% of the optimum cell power output can be easily achieved by means of a suitably controlled inverter, thereby justifying the elimination of dc loads or local dc electric energy storage devices. It is also shown that the controlling policy for the inverter must depend on …
Dynamic Simulation For Regional Energy Studies, B. W. Jones, P. M. Moretti, J. H. Mize
Dynamic Simulation For Regional Energy Studies, B. W. Jones, P. M. Moretti, J. H. Mize
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
A series of models has been developed for regional studies of energy supply- demand systems. The models are based on dynamic simulation of components of the system using equations derived from the technical details of the system. The models contain sufficient detail to make in-depth studies and specific recommendations. The final goal is to include all aspects of regional energy systems from native supplies of energy resources to the economic activities of the region.
To develop a comprehensive model, the system has been partitioned into subsystems, so that a detailed model can be made for each subsystem. The detailed model …
How Might Synthetic Fuels From Coal Affect Natural Resources And Environment?, H. J. Plass Jr.
How Might Synthetic Fuels From Coal Affect Natural Resources And Environment?, H. J. Plass Jr.
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Energy self-sufficiency for the U. S. requires substantially increased use of coal. Direct combustion of coal without adequate environmental controls, as would occur if coal were used as a fuel for homes and offices throughout the country, would result in severe air pollution problems„ Synthetic fuels from coal such as methane, low BTU gas, or hydrogen, when utilized by the homes and businesses as gas or as electricity from gas, will contribute a much smaller amount of air pollution. However, to make these synthetic fuels available, it is necessary to mine more coal than would have to be mined for …
Alcohol Assisted Hydrocarbon Fuels: A Comparison Of Exhaust Emissions And Fuel Consumption Using Steady-State And Dynamic Engine Test Facilities, D. J. Bushnell, J. M. Simonsen
Alcohol Assisted Hydrocarbon Fuels: A Comparison Of Exhaust Emissions And Fuel Consumption Using Steady-State And Dynamic Engine Test Facilities, D. J. Bushnell, J. M. Simonsen
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
This paper presents experimental data which exemplifies the differences in emission level testing on internal combustion engines when dynamic engine tests are used instead of steady-state engine tests. A comparison of the two test methods is made using hydrocarbon fuels with varying amounts of methanol. Emissions measured include the nitric oxides, unburned hydrocarbons and carbon monoxide. Emission levels and fuel consumption are reported for the various volumetric percentages of methanol in the fuel.
Of special significance are the different trends the emission levels establish when subjected to a dynamic engine test as compared to the results for the steady-state tests. …

Arctic Ecology: A Decade Of Experience, John F. Schindler
UMR Journal -- V. H. McNutt Colloquium Series
A quick glance at the title of this presentation and the reader braces himself for another antipollution or “save-the-sod” type of discourse that has become so popular these days. I do not wish to detract from the importance or the need for such efforts but I would like to address myself to the the broader meaning of the term.
Ecology--the word comes from the Greek root “oikos” which means house or household. What I’d like to do is to tell you about this “house” I’ve been living in for the past 10 years.

The Environmental Challenges Facing Taps, A. V. Cardin
UMR Journal -- V. H. McNutt Colloquium Series
Before the potential benefits of the recent oil discoveries on the North Slope of Alaska can be realized, the oil must be transported to refining and marketing areas. The Alyeska Pipeline Service Company has the responsibility for the first step in this transportation—to design and construct the Trans Alaska Pipeline System. We will pipe the oil from the discovery areas near Prudhoe Bay to an ice-free, deep-sea tanker loading terminal at Valdez of the South Coast of Alaska. From Valdez the oil will be transported to the West Coast by tankers. This is the most feasible system of a number …
The Environmental Challenges Of Alaskan Mineral Development, Earl T. Hayes
The Environmental Challenges Of Alaskan Mineral Development, Earl T. Hayes
UMR Journal -- V. H. McNutt Colloquium Series
To meet the challenges and to develop Alaska as a source of mineral and fuel resources that are essential to all of us, we must conduct the research and planning necessary to see that the environment is not abused. We cannot allow ourselves the luxury of thinking that we alone know what is best for Alaska. We must strive for cooperation -- cooperation between government and industry; between Federal and State governments; between the doer and the dreamer; and between the engineer and the ecologist. Remember, the quality of what we do today will determine the quality of Alaska in …

Mineral Potential Of Arctic Canada, R. G. Mccrossan, R. M. Procter
UMR Journal -- V. H. McNutt Colloquium Series
Canada is on the threshold of a major new phase in the development of its Arctic resources. The Prudhoe Bay discovery triggered a boom in northern petroleum exploration that is just getting into high gear this year. Mining activity also has greatly expanded in the last few years with some 73 active exploration programs underway and several large new mines just coming into production. The size of these ventures is indicated by ore reserves of two lead-zinc mines to the value of 900 million dollars at Pine Point in southern Northwest Territories, and 1.2 billion dollars at the Anvil property …

Arctic Pipelining -- Tough, Costly, But Feasible, William H. Pearn
UMR Journal -- V. H. McNutt Colloquium Series
The development of vitally important Arctic petroleum resources presents new and interesting challenges. Although the answers to some questions will undoubtedly undoubtedly go unresolved until considerable operating experience has accrued, we can improve our present insight through an awareness of the work performed by others under similar conditions. This presentation focuses on Soviet pipelining experience in arctic and subarctic regions of Siberia.

Drilling Problems Associated With Arctic Minerals, Robert L. Parker
UMR Journal -- V. H. McNutt Colloquium Series
With major involvements in Alaska, the experience gained from these operations reflect the success of talented personnel in meeting the challenges of climate, equipment, logistics, perma-frost, etc. Real concern stems from present delays in the Arctic program due to financing involved as well as increasing dependency of the United States upon these reserves in today’s market and supply situation.

Arctic Marine Terminals -- Some Environmental And Engineering Considerations, Robert L. Mccollom Jr., William W. Moore
UMR Journal -- V. H. McNutt Colloquium Series
Studies are presently underway to determine the technical and economic feasibility of various Arctic marine transportation systems, including ice-breaker super-tankers and submarine tankers. An important consideration in these studies is the design and construction of marine terminal facilities which will be suited to the unique problems of the Arctic. Factors which will significantly affect the design of proposed marine terminals include:
1) bathymetric configuration of the continental shelf;
2) influence of moving pack ice on artificial structures, both at the air-water interface and along the bottom;
3) lateral and vertical variations in soil conditions, including residual permafrost, which might adversely …

Arctic Oil And The S.S. Manhattan, Russell H. Venn
UMR Journal -- V. H. McNutt Colloquium Series
The discovery of oil on Alaska’s North Slope in 1968 not only focused attention on that remote part of our world, it set the stage for one of the most exciting and significant scientific expeditions of our time—the voyage of the ice breaking tanker SS Manhattan through the Northwest Passage.
In the space available I would like to discuss with you that historic expedition, how it came to be, and comment on the results, as we see them.
Oil And Gas Reserves In The Siberian Shelf, A. J. Eardley
Oil And Gas Reserves In The Siberian Shelf, A. J. Eardley
UMR Journal -- V. H. McNutt Colloquium Series
The Arctic region must be the world’s largest storehouse of liquid and gaseous hydrocarbons, and the vast Siberian region, both “on land” and “off shore” must be considered with envy by the free-world’s geologists for its oil and gas potential. It is here estimated that the off shore continental shelf of U.S.S.R. Siberia contains a reserve of 200 billion barrels of oil and 500 trillion cut. ft. of gas. These very approximate figures come from meager data obtained from the literature on oil and gas discoveries in the Siberian Arctic, the basin location of these discoveries, and the projection of …
The Role Of The Independent In Alaska's Mineral Development, D. L. Simasko
The Role Of The Independent In Alaska's Mineral Development, D. L. Simasko
UMR Journal -- V. H. McNutt Colloquium Series
In 68 years of oil industry history in Alaska, the independent has already played a substantial role. Eighty-three independent oil companies or operators have participated in drilling 82 exploratory wells or stratigraphic tests. Their activities extended from the discovery of first commercial oil at Katalla in 1902, to the extension of the Prudhoe Bay field in 1970. The success ratio for wildcat wells in Alaska is considerably higher than “outside,” and fields have all been major in statute, thereby reducing the cost per barrel of finding oil.
The most immediate deterrent to the success of the independent in Alaska is …

Maintenance And Operation Of Facilities And Equipment In The Arctic, Charles C. Norris, Charles W. Kelley, Carroll C. Livingston
UMR Journal -- V. H. McNutt Colloquium Series
This has been but a short sketch of a few of the problems attached to living and working in the Arctic. Much has been learned about this remote and hostile area of the world; there is much more knowledge and experience required, as has been demonstrated by the controversy surrounding the routing and construction of the Trans-Alaska Pipeline. Man’s progress depends not only on means for his survival, but also on deep ecological considerations and solid engineering.--Conclusion.
The Alaska Business Community's View Of The Development Of Alaska, William H. Scott
The Alaska Business Community's View Of The Development Of Alaska, William H. Scott
UMR Journal -- V. H. McNutt Colloquium Series
America has discovered Alaska!! Or maybe that’s just the way it seems to us Alaskans. Even though Secretary of State Seward bought the Great Land (that’s what Alaska means in native tongue) more than a hundred years ago, very little of its nature has drifted down to the “Lower 48”. That is until the great oil reserves were discovered on the now-famous North Slope. Only then was the fact of Alaska’s mineral wealth translated into something other than very general admissions that Alaska was the natural resource storehouse of the United States. Now one would naturally conclude that the Prudhoe …
The U.S. Army's Experience In Handling Petroleum In An Arctic Environment, Frederic Johnson
The U.S. Army's Experience In Handling Petroleum In An Arctic Environment, Frederic Johnson
UMR Journal -- V. H. McNutt Colloquium Series
This article pinpoints the various facets that the US Military experienced in Petroleum Operations in the Arctic environment Since the Military were the pioneers in Arctic operations, this experience could prove invaluable if and when the TAPS pipeline is constructed. The article deals primarily with various problems which beset the pipeliners during the initial construction phases and the peculiarities experienced during operations. A slightly different aspect will be experienced, however, when the Oil Industry moves relatively hot crude oil through the pipelines with TAPS since the Military moved only clean product.
The article addresses above ground pipeline operations, problems encountered …

State Regulatory Controls On Oil & Gas, Thomas R. Marshall Jr.
UMR Journal -- V. H. McNutt Colloquium Series
Alaska oil and gas regulatory matters are under the jurisdiction of a three-man Oil and Gas Conservation Committee, all of which are state employees.
In the last 10 years State water bottoms in Cook Inlet have been leased, explored and oil production amounting to about 200,000 barrels a day has been established. Cook Inlet is subject to very high tides and heavy ice flows. Five Salmon runs also occur in the Cook Inlet. The average daily production rate per well in the Cook Inlet area is nearly one hundred times the national average.

Geologic Considerations And Solid Mineral Potential Of Alaska, A. E. Weissenborn
Geologic Considerations And Solid Mineral Potential Of Alaska, A. E. Weissenborn
UMR Journal -- V. H. McNutt Colloquium Series
In marked contrast to Alaska’s petroleum industry, production from the State’s mining industry has declined drastically. Despite favorable geologic conditions, mineral exploration and development have been held back by inaccessibility, rugged terrain, severe climate, and scarcity and high cost of labor. Changing economic and political conditions, improved exploration techniques, and the ever increasing demand for minerals have again directed attention to Alaska’s mineral potential. Important discoveries in British Columbia and Yukon Territory have further stimulated exploration in Alaska. The probability that significant discoveries will result is high.
The titaniferous iron ores of southeastern Alaska probably will be brought into production …
Alaska's Possible Petroleum Provinces, George Gryc
Alaska's Possible Petroleum Provinces, George Gryc
UMR Journal -- V. H. McNutt Colloquium Series
Petroleum is the major Alaskan source of energy immediately available to the United States. Petroleum accounted for 89 percent or about $219 million of Alaska’s total mineral production in 1969 estimated at nearly $245 million.
Alaska’s first oil field was discovered at Katalla in 1902. About 154,000 barrels of oil were produced from 1902 to 1933. From 1945 through 1952, 45 shallow core tests and 36 test wells were drilled in and adjacent to Naval Petroleum Reserve No. 4 in northern Alaska. Oil deposits with possible reserves of 72 to 112 million barrels and gas deposits with possible reserves of …
