Abstract
A sol of metallic alkoxide is pumped into a desired location in a wellbore and allowed to gel, creating solids in-situ. The sol is either unstabilized, requiring rapid placement before gelling, or the sol is stabilized, permitting off-site mixing. Sols can be stabilized with either surfactant or with interfacial polymers. Large concentrations of surfactant can be placed in the sol to create templates around which gelation occurs, creating porous solids.
