Page v - Clapp. 1906. 145pp., 8 pis. B 303. Preliminary account of Goldfleld, Bullfrog, and other mining districts in southern Nevada, by FL Ransome, with notes on the Manhattan district, by GH Garrey and WH Emmons. 1907.
Page 15 - In porous rocks that are only partly filled with water, the oil accumulates at the upper limit of the saturated area. This limit of saturation traces a level line around the sides of each structural basin, but the height of this line may vary greatly in adjacent basins and in different sands of the same basin. "Partial saturation is the condition most generally found, in which case accumulations of oil may occur anywhere with reference to the geologic structure; it is most likely, however, to occur...

Page 14 - In most cases it is probable that a combination of these two conditions exist — that the porous rocks are completely saturated with water up to a certain level, but above that point they are dry. The movement of the hydrocarbons through the rocks will not be the same in the two cases, and therefore each condition must be considered separately. If small quantities of oil and gas enter a dry porous rock at different points the oil will flow down as long as gravity is sufficient to overcome the friction...

Page 15 - In porous rocks, completely saturated, the accumulation of both oil and gas will be in the anticlines or along level portions of the structure. Where the area of porous rocks is limited, the accumulation will occur at the highest point of the porous...
