Studies on Clay Minerals and Some Properties of Sedimentary Rocks in Oil-bearing Areas in Japan (1)

Abstract

In Japan, we have many shale troubles such as, heaving, sloughing, balling, or severe effects on mud viscosity.
In the report 1 to 4, the author describes following studies.
1) Suspending ability of shales in fresh water and swelling ability of clay minerals in shales.
2) Clay minerals in shales by X-ray diffraction methods.
3) Phenomenons of shales in fresh water and several electrolyte solusions.
4) Relations between phenomenons in fresh water and electrolyte solutions and clay minerals and adsorbed ions in shales.
