"INTRODUCTION AND SUMMARYNowata County, in the northeast corner of Oklahoma, is one of the principal oil-producing counties of this stripper area. Many fields in the county were opened and much oil was produced before statehood. The location of the major fields, as defined by the Oklahoma Corporation Commission, 2/ the outline of the areas of water-flooding activity, and the location of the several projects described in detail in this report are shown in figure 1.There was some drilling in the county earlier; but it was not until after 1904, when the Secretary of the Interior confirmed as valid the leases granted by the Cherokee Nation, that the major drilling activity began. Initial development in this part of Oklahoma was in the Chelsea field in Rogers County, which adjoins Novata County on the south. The activity spread rapidly northward to the Alluwe and Coody's Bluff fields, and then to the Nowata-Claggett field. Continued exploration resulted in discovery of the Delaware-Childers field, where some wells having an initial production of 1,000 barrels daily were completed. Fields discovered and developed during the next few years included the Lenepah (Elliott), Adair, California Creek, Curl Creek, Woody, and South Coffeyville. The oil-production history of Nowata County is shown in figure 2. In assembling the data for a production curve, it was found that the combined production records for Nowata and Rogers Counties were available for 1914 to 1951, inclusive, and that records for the individual counties were available only from 1926 to 1951, inclusive. The early production figures for the counties from 1905 to 1914, inclusive, except for 1909, were calculated from the initial production statistics of the Federal Geological Survey mineral resources bulletins and production data assembled by C. H. Beal. 3/ The production values for 1905 to 1926 for Nowata County were obtained by dividing the total production for the two counties by a percentage factor derived from known facts regarding the oil industry in the area. Production figures for the individual counties from 1926 to 1933, inclusive, were obtained from the files of the Oil and Gas Journal, and the figures from 1933 through 1951 were obtained from monthly reports of the Oklahoma Corporation Commission."

The investigation to evaluate the reserves of coking coal is being made by the Bureau of Mines in three parts: (1) To estimate known measured and indicated recoverable reserves of all coking coal; (2) to upgrade marginal coals through effective preparation; and (3) to study the carbonizing properties of coal and coal blends not now widely used for metallurgical coke making. This is the tenth of a series of reports giving the results of studies by counties under part (1) of the investigation. (See appendix.) This report covers Knott County, Ky., which comprises parts of the Salyersville, Prestonsburg, Troublesome, Hindman, Pikeville, Cornettsville, and Whitesburg quadrangles. (See fig. 1.) A base map for each bed in each quadrangle was made to the scale 1 inch equals 1,200 feet. Maps of mines, locations of drill holes, bed and total coal thicknesses, and the outcrop of the bed were plotted on the maps. With all available data plotted, isopach lines were drawn to limit areas of known unmined reserves in beds up to 14 inches thick, 14 to 28 inches thick, 28 to 42 inches thick, and over 42 inches thick. These areas of coal reserves also were divided into "measured" and "indicated" categories. All areas in each thickness range and category, mined-out areas, areas excluded from the estimate but which may contain reserves based only on geologic inference, and areas outside of the outcrop were measured by planimeter on the base maps. Estimates of total reserves 14 inches and more thick and maps for individual beds were prepared from these data.

A laboratory method for examining crude shale oil is described. The method uses only about 500 ml. of sample and a limited number of analytical determinations. Results provide information on the general characteristics and composition of an oil and serve as a basis for comparing different oils. However, the method does not provide for direct estimates of yields of commercial products. Analyses of 10 oils produced in the United States by different methods of retorting and of 10 shale oils from commercial-scale operations in 6 foreign countries are given. The shale-oil-analysis method presented in this paper is based on and employs the same equipment as the Bureau of Mines routine method for analyzing crude petroleum. As shale oil contains groups of compounds not generally found in petroleum, several modifications of the petroleum method that might increase its suitability for application to shale oil were investigated. The modifications included in the present method take into account the apparent poor heat stability of shale oil and the presence of large quantities of olefins and nitrogen compounds.

As part of the important program of promoting conservation and efficient utilization of petroleum, Bureau of Mines engineers are making studies of secondary oil-recovery projects throughout the United states and publishing reports setting forth the pertinent facts so that others may profit by the experience gained. This report presents the results of a study by engineers of the Bureau of Mines, stationed at Franklin, Pa., of secondary oil recovery in a part of the Cabin Creek field, Kanawha and Boone Counties, W. Va., where natural gas is injected into the reservoir to stimulate oil production. Most oil produced in the Appalachian region at present is obtained from stripper fields in which almost all natural energy has been dissipated. Secondary-recovery methods are used extensively in many oil-producing areas of New York, Pennsylvania, West Virginia, Ohio, and Kentucky for recovering oil not produced by primary-production methods. The part of the Cabin Creek field reported in this study is shown in figure 1 and has been designated by the operator as project 4. In 1944 the developed area of the entire field was approximately 4,200 acres, and the area of project 4 was about 600 acres. In the developed area of the project the oil reservoir is in the Berea sandstone and occurs at 2,914 to 3,410 feet.

Thallium is one of the rarer metals that has come into commercial importance in recent years. Although the element was first reported by Crookes in seleniferous deposits in lead chambers of a sulfuric acid plant in the Harz Mountains of Germany, it had no commercial significance until about 190O because of the high cost of extraction. Thallium occurs widely in the earth's crust but is found in such low concentrations that it is recovered only as a byproduct from processing other elements. There are no domestic ores of thallium; the entire output in this country is supplied by the American Smelting & Refining Co. as a byproduct of its cadmium operations at Globe, Colo. Thallium also is recovered from the flue dusts of sulfuric acid works in which thallium-bearing materials are used and as a byproduct of the lithopone industry. This paper describes methods for recovery of thallium from 'white arsenic" and lead Cottrell-precipitator dust of the American Smelting & Refining Co., lead smelter, Murray, Utah. Owing to an enlarged market for thallium because of increased military requirements and expanded peacetime uses, the Salt Lake Station of the Bureau of Mines surveyed the occurrence of thallium in ores, concentrates, and smelter products from all parts of the nation and found the most promising source was certain smelter products of the American Smelting & Refining Co. plant, Murray, Utah. Much of the thallium was being lost in marketed arsenic products; therefore, this investigation was undertaken to develop methods for recovering the thallium.

A summary of the characteristics of motor gasoline for the winter 1951-52 is presented in table I, and for comparison, a similar summary for the winter 1950-51 is shown in table 2. Trends of some of the more important characteristics over a period of years are shown in figures 1 and 2. The results of this survey show that octane numbers have risen slightly since the summer of 1951 but are below the record levels of the winter of 1950-51. The fractions of a unit change since the summer preceding have resulted in the research and motor-method octane values being virtually the same as the figures for the survey of summer 1950. In volatility characteristics the winter gasolines have changed very little. Average Reid vapor pressures are 10.5 pounds for both grades of fuel compared to 10.4 and 10.5 pounds for premium and regular-price gasolines, respectively, of the winter of 1950-51.

A method has been developed in the laboratory for successfully treating titaniferous magnetite ore from the deposit at Iron Mountain, Wyo. The ore is roasted with 15 percent sodium carbonate to convert the vanadium to a water-soluble form and fix the soda for the subsequent electric-smelting step. Approximately 90 percent of the vanadium is recoverable in a product assaying 80 percent V2O5. The leached calcine is briquetted and smelted in a graphite-lined electric-arc furnace. Substantially all of the titanium is recovered in a soda slag, assaying 60 percent TiO2 and 2 percent Fe, which can be upgraded to 75 to 80 percent TiO2 by leaching with dilute sulfuric acid. The upgraded slag could be utilized for the production of titanium dioxide pigments or titanium tetrachloride. About 90 percent of the iron is recovered as pig iron, containing only minor amounts of vanadium, titanium, and sulfur. The high TiO2 slag compares favorably with slag containing about 70 percent TiO2 being produced by the Quebec Iron & Titanium Corp. at Sorel, Quebec. The data obtained from this investigation indicate that a feasible process has been developed for treating Iron Mountain ore, and larger-scale testing is warranted to develop engineering data for the ultimate utilization of this deposit as a source of titanium, iron, and vanadium. There are adequate supplies of basic raw materials, electric power, water, sodium carbonate, coal, and petroleum products within fairly short distances of Cheyenne and Laramie, Wyo., the nearest cities and probable plant- and labor-supply points.

When electric current of any appreciable magnitude flows from a power line into the earth, a change sometimes takes place in the conditions of resistivity immediately surrounding the electrode or medium of contact. If the conducting medium is composed of moist earth or clay the effect is to increase rapidly the resistance. If the conducting medium is coal or a coal bed, the effect is one of slowly decreasing resistance as the coal is carbonized, If, however, the flow of current is not enough to carbonize the coal, it will dry slowly, with a resultant increase in resistance. Measuring ground resistance, or impedance, with conventional commercial ground testers does not always indicate the current that will flow in the earth circuit from a direct-current or an alternating-current power circuit. The exact reason for this has not been determined however, it is thought to be due to the comparatively minute currents used for such testing. A typical ground, tester used by the authors for this work indicated a maximum current of 25 milli-amperes. The frequency of this testing current also has an effect on the readings in all probability. While the possibilities of the effects of varying frequencies has by no means been fully explored in this investigation, there are very definite indications that the impedance of a circuit through a section of earth will vary in some inverse relationship to the frequency of the applied voltages. This is evident at ordinary power-line frequencies ns well as at higher frequencies up to 200 kilocycles, which was the highest frequency available for tests in this investigation. This report is written in the hope that it will stimulate further investigation of the possibilities suggested for communication and the development of safety devices for increased electrical safety in coal mining.

An important phase in the Bureau of Mines investigation of electrical machines designed for operation in gassy coal mines is testing enclosures of electrical components for explosion-proof qualities. In brief, this testing consists of filling and surrounding the enclosure with an explosive atmosphere of methane and air and then igniting the atmosphere within the enclosure to determine (1) Whether the resulting explosion is confined without discharge of flame; (2) whether the enclosure walls are permanently distorted; and (3) whether excessive pressures are developed within the enclosure. Ordinarily, the pressures encountered in routine testing do not exceed 100 pounds per square inch gage. Hence, the designer of the machine does not have too much difficulty in taking corrective measures to prevent flame discharge and distortion of the enclosure. Occasionally, however, the explosion pressures greatly exceed 100 pounds. Then the goblet of the designer may not be solved so readily, From experience over the year 0, the testing personnel often can predict that certain construction will result in high. Pressures, but, only in a very general way, has it been possible to advise designers what modifications might be made to reduce the explosion pressures to normal values. For example, if high pressures were developed in a motor starter having a partition with an opening through it, some enlargement of the opening may appear to be the logical procedure, but it has not been- possible to give information concerning the exact amount the opening should be enlarged to prevent development of high pressures .

Improvements in production of high-purity chromium metal by magnesium reduction of anhydrous chlorides and by hydrogen treatment of electrolytic chromium are reported. Hydrogen-treated chromium has been arc-melted, and the arc-melted material has been successfully forged, rolled, and swaged. The material also has been forged at liquid-air temperatures. X-ray and metallographic studies indicate the recrystallization temperature of rolled chromium sheet to be about 750° C. Preliminary investigation of hot-bending characteristics of rolled chromium sheet shows the minimum bending temperature to be about 325° C. The heat resistance of chromium has been investigated.

This report covers the investigation of the MacArthur copper deposit and several adjacent claims in the Mason mining district; Lyon County, Nev. (fig. 1). As a part of the Bureau of Mines program of investigation and development of domestic mineral deposits, a project was begun first on the MacArthur claims. Work was done later on some adjacent claims in the immediate area, as shown by figure 2. Field work was begun by the Bureau of Mines on January 16, 1950, and completed on October 25, 1950. Eight diamond-drill holes were completed, for an aggregate of 3,414 linear feet, Analyses were made of' each drilling interval. The report includes a brief history of the district and a description of the deposits and of the work done by the Bureau of Mines.

Owing to the need for additional sources of supply of both zinc and lead following World War II, the Bureau of Mines investigated many abandoned lead-zinc mines in the eastern United States. A series of shallow veins in south-western St. Lawrence County has long been a subject of speculation. These veins, which average about 4 feet in width and cut across the bedding of the country rock at right angles, are filled with calcite-carrying galena and sphalerite. The deposits have been worked sporadically during the last 115 years. From 1837 to 1852 the Coal Hill, the North, and the Victoria mines near the village of Rossie were at their peak of activity. Other calcite veins were prospected and a small production was realized. The Bureau of Mines began diamond drilling May 1, 1950, under the general supervision of McHenry Mosier, chief, Mining Branch, Bureau of Mines, Region VIII, and under the immediate supervision of the author) who was project engineer, following the preliminary examination by Robert S. Sanford. A total of 3,870.2 feet was drilled in 18 holes on four of the numerous deposits scattered over Macomb and Rossie townships. Drilling was completed September 21, 1950.

This report presents the results of laboratory and continuous mill-beneficiation tests conducted at the Bureau of Mines Northwest Electra Development laboratory, Albany, Oreg., on nonsulfide lead ore from the Sherman mine, Leland district, near Burke, Idaho. The predominant lead-bearing mineral in the ore sample treated was pyromorphite, a minor ore mineral of lead. Known reserves of pyromorphite lead ore in the United States are limited, although an appreciable tonnage of this type of ore is found in the Sherman mine. Very little pyromorphite is being mined in this mine or in the United States. This beneficiation problem presented a unique opportunity to study the mineral-dressing properties of a less widely known lead mineral, and consequently adds valuable knowledge to the ways of beneficiating ores containing nonsulfide lead values. This mineral-dressing problem was successful with conventional concentration methods of flotation and Gravity separation.

Pike County in the easternmost portion of Kentucky is one of the major coal-producing areas in the eastern Kentucky coal field. The county contains numerous coal beds, many of which are too thin to support mining. The commercially important beds are usually 4 feet or more thick, but selective mining at some places calls for removal of a much thinner section of the bed. The variation in quality of the beds from place to place and the large number of coal beds make correlation uncertain. Samples were collected from 14 different coal beds, of which the Elkhorn group is by far the most important. In addition to the Upper Elkhorn No. 3, Upper Elkhorn No. 2, Upper Elkhorn No. 1, and Lower Elkhorn beds that comprise the Elkhorn group, the Winifrede, Williamson, and Bingham beds constitute the principal coal deposits in Pike County.

The Andover-Sulphur Hill iron mines in Sussex County, N. J., have a production record extending over 100 years. The last production recorded was about 1880. These mines produced high-grade ore of two types: Bed ore (hematite) and blue ore (magnetite. Some sulfides (lead, zinc, and copper) were found underlying the iron deposits. Data as to size and grade of these sulfide bodies are very sketchy, Toward. J. Hewitt of Elizabeth, N. J., lessee of the Sulphur Hill mines from 194045, prospected for lead, zinc, and copper. .His Only production was several hundred tons of low-grade iron ore, which was crushed and used as heavy aggregate to make concrete blocks for ship ballast. In October and November 1942 made a magnetic survey of this area and bored six-diamond-drill holes with the dual objective of prospecting for sulfides and testing for extensions of the iron-ore deposits indicated by the magnetic survey. In 1944, an iron-mining company examined this property and diamond-drilled seven holes Between December 1949 and March 1950, the Bureau Of Mines in search of sulfide deposits, bored three additional diamond-drill holes. Two of these were on the Sulphur Hill tract and one on the adjoining Tar Hill tract.

A process has been developed in the laboratory and expanded to semi-pilot-plant scale for recovering titania, iron, and byproducts from two types of titaniferous iron ores. A reducing roast with coke and soda ash followed by grinding and magnetic separation produced powdered iron and slag from which titania and byproducts were recovered by H2SO4 decomposition. Based on the steps tested on a. semi-pilot-plant scale supplemented by the results of the laboratory investigations, enough data are available to make a balanced flow sheet. Combined data from the laboratory and semi-pilot plant indicated that 85 to 9O percent of the titania content of the ore was recoverable and that approximately 90 percent of the iron could be recovered as a metallic-iron powder. Tahawus magnetite from the Maclntyre mine at Tahawus, N. Y., was successfully treated as follows: (1) The ore was roasted at 1,050° to 1,080° C. with carbon and soda ash, thereby reducing the iron to metal sponge and retaining the titania in the slag. (2) The metallic iron was separated, after wet grinding, by magnetic or gravity means. (3) The slag fraction was air-roasted at 850° C. and leached with NaOH to recover Na3VO4. (4) The leached solids received a dilute-H2SO4 leach to remove interfering impurities, chiefly Na2O and SiO2. (5) Titania was dissolved from the leached solids of step (4) by a H2SO4-bake followed by a water leach. (6) Titania was precipitated by seeding and boiling the resulting solution. The spent liquor was used for the dilute-H2SO4 leach in step (4). The following scheme was found to be technically feasible for recovering other byproducts of the process. (1) The gelled filtrate from the dilute-acid leach step was washed and dehydrated to produce a commercially acceptable silica gel. (2) The wash liquor containing sulfates of Na2O, Al2O3, Fe2O3, and TiO2 was combined with the highly alkaline filtrate from the wet-grind and metallic iron-separation steps, precipitating iron and titanium hydroxides, which were separated for special treatment. (3) Anhydrous Na2SO4 and Al2O3?3H2O were recoverable from the alkaline filtrate from step (2) by evaporation and carbonation, respectively, and the barren liquor was recycled to the magnetic-separation step.

The Quapaw pool is one of the smaller pools in an extensive area of Bartlesville-sand production in the eastern part of Osage County, Okla. (fig. 1). Most of the fields in this area were discovered from 1906 to 1916 and were developed and operated similarly. The Quapaw pool is representative of the area, and much of the developed in studying this pool is applicable to the other reservoirs. This petroleum-engineering study of the Quapaw pool was conducted to provide reservoir data that may aid in more widespread application of the intensive secondary-recovery production methods that have been employed with excellent results in the Bartlesville-sand fields of nearby Washington, Nowata, and Rogers Counties. This study is particularly appropriate because of the intense interest in Osage County fields as areas suitable for water flooding. Water flooding was introduced first into Oklahoma during 1931 in Rogers County, and activity was concentrated in the shallow Bartlesville-sand fields of and Nowata Counties for many years. Although water-flooding projects are now operating throughout the State, the intense activity of the Nowata-Rogers Counties area spread to adjoining counties only during the past few years. Since 1948 the rate of oil production in Washington County (between Nowata and Osage Counties) has increased by 260 percent as a result of water flooding. Currently, leases in eastern Osage County are sought eagerly by water-flood operators, and during the past 2 years the Osage Indian Agency has issued nine permits for water-flooding projects in eastern Osage County. Water-flooding operations are in progress on several projects. Although large oil reserves in eastern Osage County should, be recoverable by water flooding, development and operation of projects will be more expensive than projects in the shallower producing areas to the east. In addition, the Osage County reservoirs appear to be more complex and somewhat more difficult to water-flood successfully. It is hoped that this study will contribute to better understanding of the Quapaw reservoir and, in a general way, to the many similar reservoirs in eastern Osage County.
