COMPOSITIONS FOR INCREASING HYDROCARBON PRODUCTION FROM SUBTERRANEAN FORMATIONS Abstract of the Disclosure The present invention relates to a chemical composition represented by the formula: Formula I Image and Formula II Image wherein a is a whole number or fraction thereof in the range of from about 4 to about 18; wherein b is a whole number or fraction thereof in the range of from about 0 to about 30; wherein c is a whole number or fraction thereof in the range of from about 1 to about 3; wherein d is a whole number or fraction thereof in the range of from about 0 to about 3 and d is less than or equal to c; R is independently selected from the group consisting of hydrogen and a methyl group whereby mixtures containing both groups may result; and X+ is an exchangeable cation; and Z is a nucleophile containing species containing at least one member selected from the group consisting of oxygen and nitrogen wherein the nitrogen is in the form of NR1H wherein R1 is independently selected from the group consisting of hydrogen and methyl radicals. The invention also relates to a method of treating a car- bonate containing subterranean formation to increase the production of hydrocarbons therefrom. The subterranean formation is contacted with an aqueous solution of the composition defined above.
