Definitions
- the present invention relates to the field of the extraction of hydrocarbons and more particularly to the field of additives used to facilitate the extraction and transport of said hydrocarbons.
- the present invention relates to the use of a compound as well as to a process for limiting, or even preventing, the agglomeration and / or the formation of gas hydrates, which are commonly known to disturb the flow of hydrocarbons in the pipes for extracting and transporting said hydrocarbons.
- extracted fluids means fluids comprising petroleum, gases, condensates, water and their mixtures.
- production fluids means fluids comprising petroleum, gases, condensates, water and their mixtures.
- term “petroleum” is understood to mean crude oil, that is to say unrefined, originating from a deposit.
- the term “gas” is understood to mean crude natural gas, that is to say untreated, directly extracted from a deposit, such as for example hydrocarbons, such as methane, ethane, propane, butane, hydrogen sulfide, carbon dioxide and other gaseous compounds under operating conditions, as well as their mixtures.
- hydrocarbons such as methane, ethane, propane, butane, hydrogen sulfide, carbon dioxide and other gaseous compounds under operating conditions, as well as their mixtures.
- the composition of the natural gas extracted varies considerably between wells.
- the gas can include gaseous hydrocarbons, water and other gases.
- condensate hydrocarbons of intermediate density. Condensates generally consist of mixtures of hydrocarbons which are liquid under operating conditions.
- aqueous phase in a greater or lesser quantity.
- the origin of this aqueous phase can be endogenous and / or exogenous to the underground reservoir containing the hydrocarbons, the phase exogenous aqueous generally resulting from an injection of water, also called injection water.
- the pipes for transporting the fluids produced are often placed on the seabed, at increasingly great depths, where the temperature of the sea water is often less than 15 ° C, more often less than 10 ° C, or even close to or equal to 4 ° C.
- clathrates are solid crystals (similar to those of water in the form of ice) formed by water molecules, also called “receiver”, around one or more gas molecules, also called “guests » Such as methane, ethane, propane, butane, carbon dioxide or hydrogen sulfide.
- thermodynamic anti-hydrate or “thermodynamic hydrate inhibitor” or “THI” in English
- methanol or glycol
- THI thermodynamic hydrate inhibitor
- Another solution consists in adding a low dosage additive, called LDHI ("Low Dosage Hydrate Inhibitor”) in the fluids produced comprising the water / guest gas mixture (s).
- LDHI Low Dosage Hydrate Inhibitor
- This additive is also called an anti-hydrate and is introduced at a low dosage, generally between 1% and 4% by weight, relative to the weight of the water, it being understood that higher or lower amounts are of course possible.
- Two types of anti-hydrate additives are currently known, anti-caking agents and kinetic anti-hydrates.
- Anti-caking agents are not inhibitors of the formation of hydrate crystals, they are surfactants possessing the property of dispersing the crystals by adsorbing on them, which consequently prevents said hydrate crystals to clump together.
- the adsorption of anti-caking agents on the crystals makes the latter lipophilic, which allows them to be easily dispersed in the liquid phase hydrocarbon.
- the hydrate crystals thus dispersed can no longer clog the pipelines for transporting oil and gas production fluids, thus increasing production, in particular oil and gas extraction.
- additives used in oil and gas production such as, for example, corrosion inhibitors, kinetic anti-hydrates, anti-caking agents, anti-mineral deposits, demulsifiers, deoilers, anti-foam additives, paraffin inhibitors and dispersants, asphaltene inhibitors and dispersants, hydrogen sulphide scavengers.
- Anti-caking agents are effective when a liquid phase of hydrocarbons is present in contact with an aqueous phase circulating in the pipelines for transporting oil and gas production fluids.
- the water fraction should be less than 50%. Otherwise, the hydrate dispersion becomes too viscous to be transported.
- Document US9988568 discloses a mixture of a refined hydrocarbon and an anti-caking agent. However, an instability of the mixture is observed, the anti-caking agent being poorly miscible / soluble in the refined hydrocarbon or in the produced hydrocarbon.
- the first object of the present invention is therefore the use for preventing and / or delaying and / or preventing the agglomeration of gas hydrates, of one or more compounds of formula (1), as well as its salts:
