Abstract
(EN) A subterranean zone can be treated by introducing a mixture of an acid-generating material and a proppant (for example, in a pad fluid or a pre-pad fluid) to the subterranean zone. Fractures and microfractures are created in the subterranean zone using the mixture of the acid-generating material and the proppant. The proppant is positioned within the fractures and microfractures to keep them open.
(FR) Une zone souterraine peut être traitée par introduction d'un mélange d'un matériau générateur d'acide et d'un agent de soutènement (par exemple, dans un fluide tampon ou un fluide pré-tampon) dans la zone souterraine. Des fractures et des microfractures sont créées dans la zone souterraine à l'aide du mélange du matériau générateur d'acide et de l'agent de soutènement. L'agent de soutènement est positionné à l'intérieur des fractures et des microfractures pour les maintenir ouvertes.
