| abstract |
Compounds of the formula H(CH 2 ) z COO—[C 2 H 4 O] x C y H 2y+1 where z is 0-2, x is an integer from 1 to 5 and y is an integer from 4-9 are used as emulsion breakers and defoamers in formation treatment fluids in the recovery of hydrocarbons from subterranean formations. A preferred material has the formula HCOO—[C 2 H 4 O] 3 C 6 H 7 . |
