  • Method for predicting occurrence of microquartz in a basin
    Patent number: 9869797
    Abstract: A method, including: obtaining a grain size for amorphous silica associated with a basin and a grain size for quartz associated with the basin; obtaining kinetics of silica dissolution corresponding to the basin and quartz precipitation corresponding to the basin; determining, with a processor, a concentration of amorphous silica in water based on the grain size for amorphous silica, the grain size for quartz, and the kinetics of silica dissolution and quartz precipitation; comparing, with the processor, the concentration of amorphous silica in water to an amorphous silica saturation condition; and determining, with the processor, a presence of microquartz based on a result of the comparing.
