A method of blocking a high permeability channel in communication with a wellbore, including the steps of introducing an amount of an unreinforced gel into the high permeability channel via the wellbore and introducing an amount of a reinforced gel comprising an amount of a reinforcing material into the high permeability channel via the wellbore. The method may further include the step, after introducing the unreinforced gel and the reinforced gel into the high permeability channel, of introducing an amount of a chaser fluid into the wellbore.

This invention relates to the enhancement of chemical reactions by applying a high frequency electric field to a material. The frequency and amplitude of the electric field are selected in accordance with the properties of the reacting components in the bulk of chemical reactor. In general, the high frequency range is determined by the dielectric properties of reactant(s), that is, at any given temperature, when, for example, the specific conductivity starts to grow from its low frequency value. Typically, frequencies in the range of 100 kHz to 200 MHz or greater are suitable for the enhancement of the reactions. An electric field of any shape having Fourier components that when applied to a chemical process exhibits growth in the real part of conductivity relative to the low frequency value is of particular importance.

The present invention relates generally to the delulcanization of rubber. More specifically, the present invention relates to a process for the hydro-devulcanization of vulcanized rubber utilizing a rubber swelling solvent, a source of reactive hyrogen and elevated temperature and, optimally, also uses a dispersed molecular-scale hydrogenation catalyst that is introduced into the vulcanized rubber in a catalytically inert form that is soluable in the rubber swelling solvent.

A wet electric heating (&ldquo;WEH&rdquo;) process involves establishing electrode zones (&ldquo;e-zones&rdquo;) around conductors (e.g., wells) for distributing electric current and thereby generating and distributing heat accordingly through a target region in a subterranean formation having hydrocarbons. The inventive WEH process takes into account e-zone geometric shape, spacing and/or spatial orientation to provide a more diffuse distribution of increased temperature values within the target region, compared to conventional electric heating processes, during at least the first 10% of a time interval when an electric potential is applied. The most significant source of heating for diffuse distribution of increased temperature values in the inventive WEH process arises from electric energy delivered directly to and throughout the target region, namely an electric heating distribution effect, which significantly reduces reliance on thermal conduction and/or fluid convection in distributing heat relatively early in the process of generating heat by electric ohm-heating.
