Abstract: A reservoir fluid can be produced from a subterranean formation. The reservoir fluid can include water and hydrocarbons such as oil. It is oftentimes desirable to limit the amount of water that is produced, so a higher ratio of hydrocarbons can be produced. Portions of the subterranean formation can have an initial permeability to water. A relative permeability modifier can be used in these portions to restrict or prevent water from being produced. The relative permeability modifier can increase the hydrophobicity of the portion that allows the hydrocarbons to flow through while substantially limiting the amount of water. The relative permeability modifier can be a surfactant. The surfactant can be an acid or a salt of the acid. The relative permeability modifier can coat the surfaces of substances in the formation whereby the permeability to an aqueous fluid is reduced from the initial permeability.

Abstract: A reservoir fluid can be produced from a subterranean formation. The reservoir fluid can include water and hydrocarbons such as oil. It is oftentimes desirable to limit the amount of water that is produced, so a higher ratio of hydrocarbons can be produced. Portions of the subterranean formation can have an initial permeability to water. A relative permeability modifier (RPM) package including a surfactant and a polymer can be used in these portions to restrict or prevent water from being produced. The relative permeability modifier package can increase the hydrophobicity of the portion that allows the hydrocarbons to flow through while substantially limiting the amount of water. The relative permeability modifier can coat the surfaces of substances in the formation whereby the permeability to an aqueous fluid is reduced from the initial permeability. The formation can be a high-temperature formation of 230° F. (110.0° C.) or greater.

A suspending agent can be included in the liquid concentrate to distribute and suspend the friction reducer throughout the continuous phase. The suspending agent can form micelles that form a mesh-like network to distribute and suspend the friction reducer. A portion of the liquid concentrate can be added to a base fluid at the wellsite to form the treatment fluid. The treatment fluid can be a fracturing fluid.

The elastic sealant compositions may be used for downhole and pipeline applications. For instance, the elastic sealant compositions may be placed into annular space or on top of a packer to seal off fluid flow from water and/or gas zone downhole. The elastic sealant compositions may also be used for pipelines where they may be able to withstand the potential change in diameter without breaking apart. The elastic sealant compositions may be used as pigs for pipelines, for example.
