    Abstract: There are proposed inhibitors of corrosion by CO2 and H2S in water-in-oil emulsions, containing a) imidazoline or tetrahydropyrimidine derivatives of the general formula I and/or b) their open-ring precursors of the general formula II where in the formulae I and II the radical R stands for C7-C22-alkyl or -alkenyl, n stands for an integer 2 or 3, x denotes an integer from 0 to 5, Y stands for H, C8-C18-alkyl or -alkenyl, and in which in the formula I the radical Y can also stand for with the above substituent meanings and in which in the formula II the radical Y can also stand for with the above substituent meanings.n

    Abstract: The invention relates to a process for optimizing the properties of aqueous polymer solutions used for polymer flooding which comprises treating the polymer solutions under turbulent flow conditions in dynamic fluid dispersing or pumping equipment such that the residence time of the polymer solution in this equipment is less than approximately 20 seconds and the pump energy used is from about 1 to about 15 watts/liter of solution processed. This process permits the optimization of flow properties important in polymer flooding which results in the improved efficiency of the polymer flooding process.
