Summary
A unique calcium-free aluminum-based cement formulations were designed for applications under supercritical conditions and in corrosive environments. In these cement formulations alkali activation of aluminum hydroxide at high temperatures leads to the formation of mineral phases stable under supercritical and superhot conditions. As a result of the composition stable under the extreme conditions porosity and mechanical properties of this cement formulations persist through super-critical curing.
Description
The new materials are unique cementitious formulations that do not include calcium into their composition. They are stable under supercritical conditions where currently there are no proven cement solutions. Their high aluminum and low calcium content gives them the properties that are of particular interest for very high temperature geothermal wells.
Benefits
Development and exploitation of super-critical geothermal wells may increase energy production by 10 times per well over conventional geothermal plants. One of the necessary components for the construction of hot-temperature wells are materials that can survive under the well conditions. Therefore, these unique calcium-free aluminum-based cement formulations were designed for applications under supercritical conditions and in corrosive environments.
Applications and Industries
Supercritical and superhot geothermal wells are an attractive source of clean energy available 24/7. However, currently there is no durable cementing solution for construction of supercritical and superhot wells. This invention provides cementitious materials for applications in super-hot and supercritical underground wells.
