Title: Genesis of Oil by High Radial Axial Pressure

Author(s): Kunio Uwatoko (2)


This paper gives details regarding high-pressure experiments performed with oil shales from Colorado, California, and Fushun, and bituminous coal from Fushun. The test pieces were subjected to high radial axial pressure under similar conditions. It is a remarkable point that all the tests were conducted without showing any yielding by either fracture or flow, and without any effect of thermal change under high pressure.

In all of the present experiments, liquid oil was generated, and the pressure appears to have had some effects on the solubility of the bituminous matter.

It is generally concluded, judged from the experiments, that the high radial axial pressure (hydraulic pressure) on oil shales and coal at room temperature has quantitatively some importance in the generation of liquid oil from such bituminous rocks.
