Title
(EN) METHOD FOR TREATING KEROGEN, USING A COMPOSITION COMPRISING A POLYMER-ENCAPSULATED CHLORATE/BROMATE BREAKER AND A REDUCING AGENT
(FR) PROCÉDÉ DE TRAITEMENT DE KÉROGÈNE AU MOYEN D'UNE COMPOSITION COMPRENANT UN BROYEUR À BASE DE CHLORATE/BROMATE ENCAPSULÉ DANS UN POLYMÈRE ET UN RÉDUCTEUR
Abstract
(EN)
Compositions and methods for treating kerogen in a subterranean formation by generating bromine and other halogens in situ in a subterranean formation. In some implementations, the generation of the bromine or halogen is delayed. This can occur, for example, by the decomposition of precursors, a chemical reaction, the encapsulation of precursors or reactants, or a combination of these approaches.
(FR)
L'invention concerne des compositions et des procédés de traitement de kérogène dans une formation souterraine, par génération de brome et d'autres halogènes in situ dans la formation souterraine. Dans certains modes de réalisation, la génération de brome ou d'halogène est retardée. Cela peut se produire, par exemple, par décomposition de précurseurs, par réaction chimique, par encapsulation de précurseurs ou de réactifs, ou par une combinaison de ces approches.
