Compacted clay has traditionally been used as a lining material in municipal solid waste landfills. However, natural clays may not always provide good contaminant sorption properties. One alternative material that is abundant in some parts of Europe and Turkey as well as Western United States is sepiolite. A laboratory study was undertaken to investigate the feasibility of sepiolite as a liner ...

Many soluble rocks will dissolve when in contact with fluid such as water. This transformation of rock solid into flowing may trigger the creation cavities which further lead to either smooth subsidence or sudden collapse land surface. Dissolution phenomenon can be natural human origin. paper deals problem dissolution underground and geomechanical consequences subsidence, sinkholes collapse. In...

Abstract Geomechanical analysis is essential to assess the productivity forecast of cyclic steam simulation (CSS) operations in heavy oil reservoirs. The high-temperature and high-pressure fluid injection, as well depletion unconsolidated poorly cemented porous media during CSS, may generate a relevant stress–strain response at levels that can lead irreversible changes reservoir permeability. T...
