The invention also concerns said corrosion-inhibiting formulations comprising at least one compound A.

Anti-corrosion formulations with storage stability

Provided is a composition comprising at least one polymer, the repeat unit of which comprises at least one amide functional group, at least one polyetheramine with a weight-average molecular weight (M) of greater thang.mo1and exhibiting at least two secondary and/or tertiary amine functional groups, and optionally, but preferably, at least one organic solvent. Also provided is method of using of the composition for delaying, indeed even preventing, the formation of gas hydrates, in particular in a process for extracting oil and/or gas and/or condensates, and also to the process for delaying, indeed even preventing, the formation and/or the agglomeration of gas hydrates, employing a composition as defined above.

Composition which makes it possible to delay the formation of gas hydrates

The present invention concerns the use of at least one compound A comprising at least one &#x2014;SH or &#x2014;S, Mgroup, at least one &#x2014;C-G-C&#x2014; chain, in which G represents an atom from column 16 of the periodic table, not comprising a carboxy group &#x2014;C(&#x2550;O)&#x2014;OH or &#x2014;C(&#x2550;O)&#x2014;O, and of a molar mass of between 90 g&#xb7;moland 1000 g&#xb7;mol, as an additive in a formulation inhibiting corrosion in metals used in the oil industry, and more generally in any kind of industry involving the drilling of ores or fossil compounds, such as gas or oil, in order to improve both the anti-corrosion performance and the storage stability of same. The invention also concerns said corrosion-inhibiting formulations comprising at least one compound A.

Provided is a composition that includes (i) at least one compound represented by formula (I) as defined herein or a salt thereof and (ii) a nonionic surfactant. The composition is useful for limiting or preventing the formation and/or agglomeration of gas hydrates, by combining the composition and a production fluid that includes an aqueous phase and one or more gases.

Composition for limiting the formation and/or agglomeration of gas hydrates

Provided is a process for limiting or preventing the formation and/or agglomeration of gas hydrates, comprising combining (1) a production fluid comprising an aqueous phase and one or more gasses and (2) at least one compound represented by formula (I) or a salt thereof as defined herein.

The invention concerns bifunctional compositions usable in the field of extraction of hydrocarbons, oil and/or gas, said compositions being homogeneous, clear and stable and comprising at least one anti-mineral-deposit additive, at least one corrosion inhibitor, and at least one agent for compatibilizing between the anti-mineral-deposit additive and the corrosion inhibitor.

Bifunctional anti-deposit and anti-corrosion additives

The present invention relates to formulations for inhibiting the corrosion of the metals used in the oil industry, and more generally in all types of industries for drilling for fossil compounds or ores, such as gas or oil. The corrosion-inhibiting formulations are stable during storage, and have improved properties due to the presence of at least one compound having at least one triazine unit. The invention also relates to the use of at least one compound comprising at least one triazine unit in a corrosion-inhibiting formulation, as well as to the use of said corrosion-inhibiting formulation in the oil, gas and mining industry.

Anti-corrosion formulations that are stable during storage

The subject-matter of the present invention is multifunctional corrosion inhibitors for protecting from top of line corrosion and bottom line corrosion for pipes used in particular in the petroleum industry. The corrosion-inhibiting compositions comprise, as inhibitors, at least one amine with a boiling point of between 105 and 130&#xb0; C.

Treatment process for inhibiting top of line corrosion of pipes used in the petroleum industry

This invention relates to latex dispersions that are based on (co)polymers with one or more n-alkyl(meth)acrylate monomers with n a varying from 6 to 40, and optionally one or more monomers that are not very water-soluble of the (meth)acrylic and/or vinyl type, optionally one or more polar monomers that are selected from among the (meth)acrylamides and their derivatives and optionally one or more monomers that are selected from among the ethylenically unsaturated monocarboxylic and/or dicarboxylic acids or anhydrides. These dispersions are obtained by radical-type emulsion polymerization in the presence of water. They can be used as is for the inhibition of the deposition of paraffins that are contained in the crude petroleum hydrocarbons or else diluted in one or more solvents.

The invention concerns inhibitor compositions based on fatty sulphydryl acid and poly(ethyleneamino)imidazoline salts for considerably reducing the corrosive effect of carbon brine on iron and ferrous metals. These compositions are as efficient when the corrosive medium is driven with a high flowrate and in biphasic brine/oil medium.
