A Preliminary Report On The Possibilities Of The Correlation Of Geochemical Data Relative To Oil Well Waters. A Report On The Oil Well Waters Of Greenwood County, Kansas, David Anderson Bash

Professional Degree Theses

"It is a known condition and a proven fact that vast quantities of oil and gas have been lost by the infiltration and encroachment of water in producing sands. The encroachment of water in the pay horizons has not only trapped underground oil locally and caused a great loss of production, but unless the water problem was successfully combated the amount of water entering the pay may increase to the extent of flooding an entire field. Water in an oil well so increases the lifting cost that many wells are abondoned [sic] before the normal recovery is reached"--page 2.

Relationship Between Temperature And Vapor Pressure Of Light Oils, William Orval Keeling

Professional Degree Theses

"There are a few data scattered through the literature on the vapor pressures of pure hydrocarbons, but the author has never seen a systematic study of the relationship between temperature and vapor pressures of complicated mixtures such as the various light oils encountered in refinery practice. Such data would be useful in designing equipment for distillation, steam stilling, vacuum distillation and in calculating heat balance, etc. An attempt has been made to link the vapor pressure of a light oil, at various temperatures, to the average boiling point of the oil"--Introduction, page 1.

Fluorspar Mining And Milling In Southern Illinois, Henry William Hurst

Professional Degree Theses

"Fluorspar is fully as necessary a material in certain phases of steel manufacturing as the metal that enters the furnace. Without it, the basic open hearth practice probably would not have reached its dominant position among steel-making methods. Of the entire output of fluorspar, 80 to 85 percent is used in basic open-hearth and electric furnaces as a flux and detergent and there is today no known substitute.

The mining of the ore on a large scale requires extensive underground workings, much the same as is found in metal mines. Since high extraction can not be accomplished the milling of …

A Study Of The Iodine Content Of Representative Missouri Waters, Edmond Carl Hunze

Masters Theses

"Investigations have shown that the iodine content of natural waters bears a direct relationship to the goiter incidence of a given region. A number of the states have analysed [sic] their water for this constituent in the development of this hypothesis. A search of the literature revealed the fact that with the exception of two instances the iodine content of Missouri water had not been determined. Since in certain regions of Missouri there is quite a prevalence of goiter, it was deemed important to determine the iodine content of Missouri waters. It was believed that such information would be a …

The System: Calcium Oxalate - Sulphuric Acid, Joseph Maple Wilson

Masters Theses

"The manufacture of oxalic acid includes as one of the steps in the process, the conversion of calcium oxalate to the desired oxalic acid by treatment with sulphuric acid, and the subsequent crystalization [sic] of the oxalic acid from the solution of it thus made. This investigation has dealt with this conversion step, with regard to the various factors affecting it.

Mining Methods At The Higueras District, State Of Coahuila, Mexico, Harry Herbert Hughes

Professional Degree Theses

"The Higueras district, in the State of Coahuila, Mexico, is little known even in Mexico; and it is probably safe to say that not one out of every hundred engineers in the United States has even heart of it. This is easily accounted for by the fact that the district is small and relatively unimportant economically. Also, as one becomes more accustomed to think of mines, such as some of the big copper deposits, with productions running into thousands of tons daily, there is a tendency to pass over the small ones, giving them only a passing thought, if that. …

The Fissure System Of El Potosi Mine Of El Potosi Mining Company, Santa Eulalia, Chihuahua, Mexico, Carl E. Millikan

Professional Degree Theses

"The fissures traversing the country were the means of mineralizing the district. The North-South system of fissures have been determined to be pre-mineral, hence the most important. Their intersections with cross fissures are the regions of orebodies, and the intersections have always produced ore of mineable quantity. Especially important are the intersections of fissures in the "favorable" (fossiliferous) limestone beds. The favorable limestones are easily recognizable and can be traced thru all parts of the district because of their distinctiveness and the uniformity of the structure of the region"--Summary, page 19.
