Abstract: A process treats production water resulting from enhanced oil recovery, the production water comprising an aqueous phase and an organic phase dispersed in the aqueous phase, and at least one polymer in the aqueous phase. The process includes:



a step of bringing said production water into contact with an additive comprising at least one tetrakis(hydroxymethyl)phosphonium salt (THMP salt),
a step of separating the aqueous phase and the organic phase of said production water comprising said additive, by means of a hydrocyclone.

An enhanced recovery process uses a step of treating the production water according to the invention.

Abstract: The invention relates to a method of characterizing and of quantifying carbon in a superficial deposit. The sample of the formation is subjected to heating in an inert atmosphere with at least six isothermal stages connected by a thermal gradient, the sample residue is subjected to heating in an oxidizing atmosphere, and the quantities of HC, CO and CO2 released during heating are measured. A ratio of the mineral carbon to the total carbon of the sample is determined, and the at least one of the organic carbon and mineral carbon content of the sample is determined according to this ratio: (i) by accounting for an estimated quantity of CO2 released by thermal cracking of the organic matter of the sample during heating in the inert atmosphere if the ratio is substantially non-zero; (ii) if the ratio is substantially zero and the mineral carbon content is zero.
