Patent

CA 2599211

The invention relates to the use of alkane sulfonic acids, in particular methane sulfonic acid for increasing the permeability of underground petroliferous and/or gas-bearing carbonate rock formations and for dissolving carbonate contaminants and/or contaminants containing carbonates during petroleum production, especially at a temperature of at least 100 ~C.

L'utilisation d'acides alcanesulfoniques, notamment d'acides méthanesulfoniques pour augmenter la perméabilité de formations rocheuses conduisant le pétrole brut et/ou le gaz naturel carbonatiques et souterraines, et pour détacher les impuretés carbonatiques et/ou contenant du carbonate lors de l'extraction de pétrole, notamment à une température de 1000 °C minium.
