Mineral Potential Of Arctic Canada, R. G. Mccrossan, R. M. Procter
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
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
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
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
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
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 …

The Future Of Anchorage, Claire O. Banks
UMR Journal -- V. H. McNutt Colloquium Series
So, in conclusion ... our Air Crossroads of the World contemplates its future, from a similar position as that of the ancient Greeks, or later the city of Rome... and much later ... England — the trade center of its time, between East and West — North and South. In any event, we are in the enviable position of being able to determine our future. Aside from the tremendous growth and build-up factors, we are unique because of our urbanity ... nowhere else are the advantages of modern day living offered to the extent they exist here, while at the …
State Regulatory Controls On Oil & Gas, Thomas R. Marshall Jr.
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.
The Prudhoe Bay oil field discovered in …
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 …

UMR Journal -- V. H. McNutt Colloquium Series
Because this university, formerly under the well known title of Missouri School of Mines and Metallurgy, has contributed so much to the nation’s and world’s mineral supplies through the work of its well trained graduates, it was considered appropriate that a major symposium be held during its Centennial Year on one of the last major mineral frontiers of the United States......Alaska.
Preliminary planning for the symposium on “Alaska, Its Mineral Potentials and Environmental Challenges” began in the fall of 1969. In January, 1970, Robert E. Carlile and Paul Dean Proctor visited Alaska to meet with some of the petroleum and …

Petrology And Structure Of Eastern Monte Largo Hills, New Mexico, Jan Ralph Huzarshi
Petrology And Structure Of Eastern Monte Largo Hills, New Mexico, Jan Ralph Huzarshi
Earth and Planetary Sciences ETDs
In the Monte Largo Hills in the central part of north-central New Mexico, Precambrian metamorphic and igneous rocks, Paleozoic sediments, and Tertiary intrusive and extrusive igneous rocks occur. The metamorphics consist of a series of quartzo-feldspathic gneiss, mica schist, metaquartzite, and hornblende schists. These rocks were
derived from Precambrian sediments, mostly sandstones, arkoses and impure dolomites that were subjected to amphibolite facies synkinematic metamorphism. The Precambrian alkali granite appears to have been allochthonously emplaced with evidence near the contact of the quartzofeldspathic metamorphics for a parautochthonous formation. Quartz veins and pegmatite dikes of Precambrian age are also present. The sediments …
Regressive And Transgressive Phenomena In The Gallup Sandstone In The Northwestern Part Of San Juan County, New Mexico., Francis Amrisar Kaharoeddin
Regressive And Transgressive Phenomena In The Gallup Sandstone In The Northwestern Part Of San Juan County, New Mexico., Francis Amrisar Kaharoeddin
Earth and Planetary Sciences ETDs
The sedimentary history of the Gallup Sandstone is studied through the field investigation and laboratory analysis of samples taken from four measured sections in the vicinity of the San Juan River and one section near the Red Rock Highway. In addition to field data, textural parameters and dolomite and glauconite content of sandstone samples are the basis for interpretations of the sedimentary history and environment of deposition of the Gallup Sandstone.
A plot of the mean grain-size and sorting along with stratigraphic sections reveals that most of the Gallup Sandstone was deposited in a regressive sea, and that the regression …
