Abstract: System and methods of optimizing proppant placement for stimulation treatments are provided. Properties of a reservoir formation and a treatment fluid to be injected into the formation are determined for a multistage stimulation treatment to be performed along a wellbore drilled within the formation. A proppant transport model uses the properties to determine a proppant profile for a fractured area of the formation for each treatment stage along the wellbore. A proppant pack conductivity for each stage is determined based on a proppant conductivity model and the proppant profile for that stage. A rate of hydrocarbon production expected from the wellbore is estimated based on a well production model and the proppant pack conductivity. A distribution of proppant to be injected into the formation during the treatment is determined, based on the production rate and one or more constraints. The stimulation treatment is performed based on the determined proppant distribution.

Abstract: Methods and systems for protecting acid-reactive surfaces, particularly during subterranean treatment operations in which acids are used. In some embodiments, the methods include: providing a fluid additive including an organic compound and a base, wherein the organic compound includes a phosphonoalkyl moiety; providing an acid or acid generating source; mixing at least the fluid additive and the acid or acid generating source to form a treatment fluid; and introducing the treatment fluid into at least a portion of a subterranean formation.
