Encapsulated porous proppant
Abstract
The present disclosure describes proppant materials encapsulated with a polymer encapsulation layer. Proppant particles are formed with a core having relatively larger inner pores and a shell having relatively smaller shell pores. The shell pores and/or inner pores can be loaded with a treatment product, such as a methanogenic microbial consortium capable of converting coal into methane. The polymer encapsulation layer surrounds the shell and provides for sustained time-release of the treatment product when the proppant material has been delivered to a subterranean formation.
