Abstract
(DE)
Verwendung von Alkansulfonsäuren, insbesondere Methansulfonsäure, zur Erhöhung der Permeabilität von unterirdischen, carbonatischen erdöl- und/oder erdgasführenden Gesteinsformationen, sowie zum Lösen von carbonatischen und/oder carbonathaltigen Verunreinigungen bei der Erdölförderung, insbesondere bei einer Temperatur von mindestens 100° C.
(EN)
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.
(FR)
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.
