Abstract:
A composition for use in various down-hole operations in oil and gas wells. The compositions can include various combinations of certain ethers and other components e.g., esters, alkoxylated alcohols, acidizing agents and hydrocarbon co-solvents. The compositions are useful in a wide variety of down-hole applications particularly well cleaning, filter cake removal and well stimulation techniques e.g., acidizing.

Claim (Index 1):
A composition for use in down-hole operations in an oil and gas well to effect wellbore cleaning filter cake removal and/or acidizing comprising:\n A. an ether having the general formula:\n R\u2014O\u2014R 1  \u2003\u2003I \n wherein R and R 1  are each alkyl groups which, independent of each other, can be linear or branched containing from about 1 to about 29 carbon atoms, said ether being present in an amount of 40 to 90 wt %; and B. at least one additional component selected from the group consisting of:\n (i) an ester of the formula: \n \u2003wherein R 2 -R 5  are linear or branched alkyl groups having from 1 to 30 carbon atoms and n is from 0 to 20;\n (ii) an alkoxylated alcohol having the general formula:\n CH 3 (C x H 2x )\u2014O\u2014(C n H 2n O) y \u2014(C 2 H 4 O) z \u2014H \u2003\u2003IV \n \n \u2003wherein x is from 3 to 30, n is from 2 to 4, y is from 0 to 6 and z is from 3 to 20; and\n (iii) mixtures of (i) and (ii). \n (iv) an acid; and \n (v) mixtures of (i), (ii) and (iv).
