Patent ID: 7572757

Claim:
A method for treating a well penetrating a subterranean formation which comprises introducing into the well a treatment fluid comprising a gel and an effective gel stabilizing amount of a chalcogen heterocyclic electron donating compound selected from the group consisting of furan; tetrahydrofuran; 3-methyltetrahydrofuran; 2-(diethoxymethyl)furan; 2-methyl-5-(methylthio)furan; 2,3-dihydro-2,2-dimethyl-7-nitrobenzofuran; dibenzofuran; 1,2,3,4-tetrahydrodibenzofuran; 2-acetyl-5-methyl furan; 2,3-dihyrofuran; 2,2-dimethyltetrahydrofuran; 2,5-dimethyltetrahydrofuran; 2,3,4,5-tetramethylfuran; 2-methyl-5-propionyl-furan; 3-acetyl-2,5-dimethylfuran; 2-acetylfuran; 2-acetyl-2,5,-dimethyl furan; and bromotrichlorodibenzofuran, wherein the chalcogen heterocyclic electron donating compound prevents thermal degradation of the gel at temperatures to as high as 204.5° C.
