Abstract: Alkanesulphonic acid microcapsules and the use thereof as an additive for acidizing applications in carbonatic rock formations, especially for increasing the permeability of underground carbonatic petroleum-bearing and/or natural-gas-bearing and/or hot-water-bearing rock formations, and for dissolving carbonatic and/or carbonate-containing impurities in the production of petroleum and/or natural gas or in hot-water geothermal power generation. Additionally described is an acidic formulation comprising the microcapsules of the invention, and the use thereof for the aforementioned purpose, and also a corresponding process.
