Title: Further Observations on Shoestring Oil Pools of Eastern Kansas

Author(s): John L. Rich

Abstract:

Recent developments in the "shoestring" sand territory of Anderson and Linn counties, Kansas, by opening new pools and extending others, have thrown new light on the problems of the origin of these interesting sand bodies and of the accumulation of oil in them. The "shoestring" oil sands herein described lie at or close below the top of the Cherokee shale. They occupy gently winding channels cut sharply to a depth of about 50 feet into that shale. The available evidence leads to the belief that the channels were cut by streams during a slight uplift of the Cherokee sea bottom and were later silted up. The pattern of the channels as now known suggests that they are parts of a related drainage system which may ultimately be connected. The course of one of the channels is so related to the regional dip that the sand body forms a closed anticlinal trap independent of local structure. Certain of the sand bodies have been proved to extend beyond the area which is productive. The former presence of water in the sands, its relation to the present non-productive parts of the channels, and the influence of its withdrawal on the size of the oil pools and on the degree of saturation of the sands are briefly considered.
