Definitions
- the present invention relates to a method for dissolving deposits containing alkaline earth metal sulfates in underground facilities or plant components for the production of crude oil, natural gas and / or water by treating the deposits with an aqueous formulation containing methanesulfonic acid.
- inorganic or organic substances may form in the petroleum formation itself, in underground parts of the facility, such as the borehole lined with metal tubes, as well as in above-ground plant components such as separators.
- the formation of such deposits is highly undesirable because they at least hinder the extraction of oil and can lead in extreme cases to a complete blockage of the affected parts of the plant.
- oil or natural gas production is usually not only oil and / or natural gas promoted, but also more or less saline water. It may be water contained in the formation or condensed water, or water that has been injected into the subterranean formation via an injection well to maintain pressure. Saline water can also be used in geothermal energy production, in which one promotes hydrothermal water, are promoted, in which injected through an injection well cold water into a rock formation and removes warm water through a well.
- Deposits of poorly soluble inorganic salts such as deposits of calcium carbonate or calcium, strontium or barium sulfate can form, because in the rock formation under the naturally occurring conditions (high pressure, high temperature), a higher concentration of salts can be dissolved in the formation water than under normal conditions (1 bar, room temperature). If formation water saturated with inorganic salts reaches zones of low temperature and / or lower pressure on the way to the earth's surface, poorly soluble salts may precipitate, e.g. still in the formation itself, on the inner surface of the metallic lining of the production well or only in aboveground plant parts such as pipelines or separators. Furthermore, deposits can be formed by intermixing incompatible waters, such as injected water and formation water, thereby precipitating solids.
- the underground installations are a borehole or the reservoir rock, particularly preferably the borehole.
- component (III) it comprises at least one water-miscible organic solvent.
- the deposits to be dissolved in the plants or plant components are usually wetted with oil, which hinders rapid dissolution of the deposits. Organic solvents therefore allow faster separation.
- the solvents used may be wholly or only partially miscible with water. The minimum requirement is that no phase separation of water and organic solvents occurs at the concentration used and under the conditions of use.
- Suitable organic solvents include alcohols such as ethanol, n-propanol, i-propanol, n-butanol, i-butanol, glycols such as ethylene glycol, diethylene glycol, propylene glycol or glycol ethers such as ethylene glycol monobutyl ether. Of course, mixtures of several different water-miscible, organic solvents can be used.
- the formulation comprises at least one corrosion inhibitor.
- suitable corrosion inhibitors include polyether phosphates, butynediol, butynediol alkoxylates or alkyl phosphates. Of course, mixtures of several different corrosion inhibitors can be used.
