Map shows railroad lines in Barber County and portions of adjacent Kiowa, Pratt, Kingman, Harper, and Comanche counties in Kansas, noting towns and distances. It includes a key to colors (marking segments of the line in red and yellow). "No Scale."

Report issued by the U.S. Bureau of Mines on the disposal methods of oil-field brine. The study focuses on the Arkansas River area of western Kansas. This report includes tables, graphs, illustrations, and maps.

The Chemical Flooding process, like a polymer treatment, as a tertiary (enhanced) oil recovery process can be a very good solution based on the condition of this field and its low cost compared to the drilling of new wells. It is an improved water flooding method in which high molecular-weight (macro-size molecules) and water-soluble polymers are added to the injection water to improve the mobility ratio by enhancing the viscosity of the water and by reducing permeability in invaded zones during the process. In other words, it can improve the sweep efficiency by reducing the water mobility. This polymer treatment can be performed on the same active oil producer well rather than on an injector well in the existence of strong water drive in the formation. Some parameters must be considered before any polymer job is performed such as: formation temperature, permeability, oil gravity and viscosity, location and formation thickness of the well, amount of remaining recoverable oil, fluid levels, well productivity, water oil ratio (WOR) and existence of water drive. This improved oil recovery technique has been used widely and has significant potential to extend reservoir life by increasing the oil production and decreasing the water cut. This new …
