Abstract
Compositions and methods for determining the source of treatment fluids being produced from a production formation having multiple zones by introducing a treatment composition having a tracking material into a zone in the subterranean formation, and detecting the tracking material in treatment composition that flows back from the subterranean formation.
Claims28
A traceable treatment composition for treating a subterranean formation having multiple zones penetrated by a well bore comprising:
- a tracking material, wherein the tracking material is substantially non-radioactive and is selected from the group consisting of water-soluble inorganic salts, water soluble organic salts, metals, metal salts of organic acids, metal oxides, metal sulfates, metal phosphates, metal carbonates, metal salts, phosphorescent pigments, fluorescent pigments, photoluminescent pigments, oil soluble dyes, oil dispersible dyes and oil dispersible pigments.
A traceable treatment composition comprising:
- a tracking material, wherein the tracking material comprises a metal salt of an organic acid and wherein the organic acid is selected from the group consisting of substituted and unsubstituted alkanoic carboxylic acids, alkenoic carboxylic acids, polyunsaturated aliphatic monocarboxylic acids and aromatic carboxylic acids.
A proppant composition comprising a particulate material associated with a tracking composition, wherein the tracking composition comprises a substantially non-radioactive tracking material selected from the group consisting of water soluble inorganic salts, water soluble organic salts, metals, metal salts of organic acids, metal oxides, metal sulfates, metal phosphates, metal carbonates, metal salts, phosphorescent pigments, fluorescent pigments, photoluminescent pigments, oil soluble dyes, oil dispersible dyes and oil dispersible pigments.
