Abstract:
1. A method for remotely forming a barrier to seal off a remote chamber, the method comprising the steps of: a. forming a borehole that communicates between a first location and said remote chamber, said borehole opening to said remote chamber proximate a desired location for said barrier; b. inserting a conduit through said borehole to extend into said remote chamber; c. introducing a flowable material through said conduit to said remote chamber and dispensing said flowable material from said conduit to the desired location for said barrier, said flowable material comprising a first resin component and a second activator component, the first and second components of said flowable material upon being dispensed combining to produce a substantially solid, self-sustaining composition; d. maintaining dispensing said flowable material to produce a sufficient quantity of said self-sustaining composition to form said barrier to seal said remote chamber, while ensuring that said composition does not block said borehole from communicating between said first location and said remote chamber; and e. thereafter removing said conduit to allow access to said borehole.
