Abstract
A downhole fluid composition having a saccharide gelling agent, an oxidative breaker, and a sequestering agent. The sequestering agent is hydrocarbon miscible and inert to oxidation by the oxidative breaker. The sequestering agent sequesters the oxidative breaker or an activator for the oxidative breaker, whereby oxidation of the gelling agent is inhibited. The downhole fluid may also include a proppant. Upon contacting hydrocarbons downhole or reaching a predetermined temperature, the sequestering agent releases the oxidative breaker or activator thereby oxidizing the saccharide gelling agent.
