Definitions
- the present invention relates to the field of exploration and exploitation of an underground formation.
- the invention relates more particularly to the treatment of a fluid recovered from the underground formation.
- the invention relates in particular to the field of enhanced oil recovery (EOR for Enhanced Oil Recovery) and the field of treatment of production water.

- This additive can take the form of a formulation of organic molecules, such as polymers, copolymers and / or surfactants, etc.
- This formulation can also contain inorganic molecules such as minerals (clays, barite, etc.), oxide particles (titanium oxides, iron oxides, etc.) etc.
- additive (s) poses certain problems linked in particular to the presence of the additive or of molecules constituting it in the water produced.
- tertiary assisted recovery When the injected fluid, also called sweeping fluid, is supplemented with compounds, this is called tertiary assisted recovery.
- These chemical compounds are polymers, surfactants, alkaline compounds, or mixtures of these compounds.
- the hydrocarbon recovery yield is increased by means of a better formation sweeping efficiency (Han DK & al, Recent Development of Enhanced oil Recovery in China, J. Petrol. Sci. Eng. 22 (1-3 ): 181-188; 1999).
- the polymers used in this method are generally polymers of high molecular weights chosen for their viscosifying properties at moderate concentrations.
- Different techniques are applied to treat the production water, in particular to remove the dispersed crude drops: sedimentation by gravity separation, centrifugation, flotation with or without gas injection and filtration.
- the production effluent When the production effluent reaches the surface, it is treated in a surface unit. This unit makes it possible to separate the various fluids, gases, oil and water. At the end of the surface treatment, the hydrocarbons are ready to be refined. The water is treated and decontaminated in order to minimize the discharge of toxic products into the environment, the thresholds of which are subject to standards. The presence of the polymer in the fluids produced, as reported in document SPE 65390 (2001) "Emulsification and stabilization of ASP Flooding Produced liquid", can lead to the stabilization of the emulsions in the fluids produced and cause process problems. surface treatment, at the water / oil / gas separation and in particular, at the level of the secondary water treatment processes.
- the advantage of the presence of a polymer is to increase the viscosity of the sweeping water to improve the extraction of the hydrocarbons in place in the underground formation, the viscosity of the water when it is produced becomes on the other hand an obstacle to the separation between water and hydrocarbons.
- the conventional polymers used for enhanced petroleum recovery are polymers of high molecular weights which generally belong to the family of polyacrylamides (PAM) or partially hydrolyzed polyacrylamides (HPAM). They may optionally contain monomeric units of N-vinylpyrrolidone or acrylamido-tert-butyl sulfonate (ATBS) type.
- PAM polyacrylamides
- HPAM partially hydrolyzed polyacrylamides
- ATBS acrylamido-tert-butyl sulfonate
- the polyacrylamides are obtained by radical polymerization of the acrylamide according to the following general scheme. polymerization
- the partially hydrolyzed polyacrylamides are copolymers of acrylamide with either acrylic acid or an acrylate, for example an acrylate of an alkaline element such as, for example, sodium. They can be represented for example by the following general formula in which the alkaline element is sodium.
- the acrylamide monomer unit is generally in the majority.
- the partially hydrolyzed polyacrylamides can be obtained for example by copolymerization of acrylamide with acrylic acid, the carboxylic acid function of which can optionally be neutralized according to the carboxylate function of an alkaline element such as, for example, sodium.
- the partially hydrolyzed polyacrylamides can also be obtained by copolymerization of the acrylamide with an acrylate of an alkaline element such as for example sodium acrylate.
- the partially hydrolyzed polyacrylamides can also be obtained by polymerization of the acrylamide to polyacrylamide followed by a partial hydrolysis of the amide functions into carboxylic acid functions or into carboxylate functions of alkaline salts.

- the effectiveness of the treatment essentially depends on the specific reactivity of these oxidizing agents, their concentration and the conditions under which the degradation will be carried out, in particular the temperature and the reaction time.
- the operations described consist of starting from a polymer which is a conventional HPAM, to optimize the choice and the concentration of the oxidizing agent as well as the reaction conditions.

This crosslinking increases the viscosity of the fluid and / or leads to the formation of gels. This increase in viscosity is sought in order to improve the efficiency of the fluid.
