摘要： This invention relates to the recovery of petroleum, and in particular, involves a process for reducing the amount of water recovered from a producing well. This reduction in water is accomplished by: A. introducing a brine solution containing from 0.5 to 5.0 percent by weight of a surfactant into said producing well which penetrates said formation; then; B. introducing a water-in-oil emulsion into said producing well which penetrates said formation, and allowing the water-in-oil emulsion to be left static for from 10 to 72 hours; said emulsion containing dispersed therein from 0.01 to 35 percent by weight of a finely-divided water-soluble vinyl addition polymer and which is capable of being inverted in water whereby the water-soluble vinyl addition polymer is released into the water as a solution.

摘要： At least partially water soluble phosphated mixed esters of nonsurface active polyols containing at least one hydroxyethyl group and monohydric surface active compounds containing oxyethylene groups are prepared by reacting said polyols and said monohydric compounds with polyphosphoric acid or phosphorus pentoxide at temperatures of 50*C. to 175*C. The products are useful as scale inhibitors in hard waters and are especially useful in squeezetype operation in oil recovery systems where the chemical must be adsorbed on the underground formation in such a manner that it is slowly released into the water as it passes over the formation.
