Graphical Solution Of Concentration At Production Wells Of Injected Radioactive Water Tracers, George E. Vaughn Jr.

Masters Theses

"With the advent of field research in which radioactive isotopes are used as tracers for water injected in secondary-recovery operations, knowledge of the probable transit time between wells of an injected tracer, its concentration at detection points, and the resultant optimum injection concentration has become important. Both detection and, consequently, injection concentrations of radioactive tracers are at least in part functions of the loss of tracer for various reasons, flow characteristics between wells, the rate of decay of radioactive emission, and the sensitivity of the detection apparatus. A method, based on the characteristics of a homogeneous 5-spot system, has been …

An Investigation Of Some Characteristics Of Explosive Ammonium Nitrate-Reducing Fuel Mixtures, Klaus M. Kohler

Masters Theses

"It was the purpose of the investigation described herein to find the answers to some of the questions which arise with the use of an ammonium nitrate--non nitroglycerine--mixture as an explosive, such as

a) the effect of the percentage of fuel oil in the mixture

b) the effect of the loading density of the mixture

c) the effect of the diameter of the charge

d) the effect of the particle size of the ammonium nitrate

e) the effect of different reducing fuels

f) the effect of different primers"--Introduction, pages 5-6.

Application Of Statistical Methods To Evaluation Of Mineral Deposits, Francis R. Saupé

Masters Theses

"Only in recent years have statistical methods been applied to evaluation of ore reserves. An attempt is made in this study to prepare an outline to be followed throughout the exploration in order that statistical methods can be applied to valuation problems. Particular emphasis is given to the preliminary requirements to a statistical approach. Representative parameters, sampling pattern, and sample size are discussed in separate chapters"--Abstract, page iii.

A Preliminary Investigation Of Natural Gas Combustion As Applied To Thermal Recovery Of Petroleum, Roger J. Schoeppel

Masters Theses

"Present application of the subsurface combustion processes in the thermal recovery of petroleum afford favorable and opportune methods of providing greater recoveries from petroleum reservoirs. This study attempts to elucidate some of the parameters controlling the complex hydrocarbon oxidation for one such process. The experimental phase consisted of investigating the combustion behavior of eight nonexplosive and one explosive natural gas-air mixtures at low and intermediate pressures. The hydrocarbon was allowed to oxidize by self-ignition under controlled conditions within environments precluding a visible flame type reaction. Progress of the reaction was followed by measuring effluent oxygen content.

Experimental evidence indicate the …

A Comparison Of The Effect Of Pvt Data Application Methods On Predicted Depletion Drive Reservoir Performance, Frederick A. Klein

Masters Theses

"It is generally agreed that the evolution of gas from oil within a reservoir is most closely approximated by the differential liberation process, while gas liberation in the flow string, surface separator, and stock tank is most nearly represented by flash liberation. To conform with this assumed physical behavior, appropriate application of both flash and differential liberation data in the computation of reservoir performance by material balance methods is indicated.

In this work, simple depletion-drive oil and gas recoveries were calculated (1) using differential liberation data only, and (2) using differential liberation data adjusted to incorporate the results of flash …

Methods And Time Study In Mining Operations, Cyril Jones

Masters Theses

"It was the purpose of this study to evolve and present in a logical manner a method of approach from the efficiency standpoint, to mining operation problems. This, it was thought, could be best achieved by means of a method and time study program, which could examine all the operations in whatever detail was required"--Statement of the problem, page 1.
