Abstract
Official abstract text for this publication.
A method of treating a portion of a subterranean formation comprises providing a treatment fluid comprising a carrier fluid, a viscosifying agent, a breaker, and a breaker aid wherein the breaker aid slowly releases a catalyst, wherein the viscosifying agent and the breaker in the carrier fluid have an initial viscosity and the catalyst and the breaker cooperate to decrease the viscosity of the treatment fluid below half of the initial viscosity after at least 30 minutes; and treating the subterranean formation.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of treating a portion of a subterranean formation comprising: providing a treatment fluid comprising a carrier fluid, a viscosifying agent, a breaker, and a breaker aid wherein the breaker aid slowly releases a catalyst, wherein the breaker aid is selected from the group consisting of pyrite (FeS 2 ), chalcopyrite (CuFeS 2 ), magnetite (Fe 3 O 4 ), cementite (Fe 3 C), and fayalite (Fe 2 SiO 4 , the viscosifying agent and the breaker in the carrie…
