Abstract: Copolymers comprising ethylene, vinyl esters, in particular vinyl acetate and esters of (meth)acrylic acid, selected from esters comprising branched alkyl, cyclic alkyl or optionally alkyl substituted aryl moieties and having a weight average molecular weight of 35,000 g/mol to 150,000 g/mol, formulations of such copolymers in organic solvents and their use as pour point depressant, wax inhibitor and flow enhancer for crude oils.

Abstract: Use of methyl glycine diacetic acid (MGDA) as additive in processes for recovering crude oil and/or gas from subterranean formations, wherein the MGDA is a mixture of L- and D-enantiomers of MGDA or salts thereof, said mixture containing an excess of the respective L-isomer, and the enantiomeric excess (ee) of the L-isomer is in the range of from 10% to 75% Preferably, the process is a processes of acidizing subterranean formations.
