Title
(DE) VERWENDUNG VON WASSERLÖSLICHEN ALKANSULFONSÄUREN ZUR ERHÖHUNG DER PERMEABILITÄT VON UNTERIRDISCHEN, CARBONATISCHEN ERDÖL- UND/ODER ERDGASFÜHRENDEN GESTEINSFORMATIONEN UND ZUM LÖSEN VON CARBONATISCHEN UND/ODER CARBONATHALTIGEN VERUNREINIGUNGEN BEI DER ERDÖLFÖRDERUNG
(EN) USE OF WATER-SOLUBLE ALKANE SULFONIC ACIDS 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
(FR) UTILISATION D'ACIDES ALCANESULFONIQUES SOLUBLES DANS L'EAU POUR AUGMENTER LA PERMEABILITE DE FORMATIONS ROCHEUSES CONDUISANT LE PETROLE BRUT ET/OU LE GAZ NATUREL CARBONATIQUES SOUTERRAINS ET DETACHER LES IMPURETES CARBONATIQUES ET/OU CONTENANT DU CARBONATE LORS DE L'EXTRACTION DE PETROLE
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.
