Abstract: The present invention relates to a chemical composition comprising (a) a glycoside component A comprising at least one glycoside of the formula R(OG) x wherein R is an aliphatic hydrocarbon radical having 1 to 25 carbon atoms or is a radical of formula R1(OR2)m which does not have more than 25 carbon ato ms and wherein n = 0 to 24 and R1 and R2 are aliphatic hydrocarbon radicals; G is the residue of a saccharide moiety selected from the group consisting of fructose, glucose, mannose, galactose, talose, gulose, allose, altrose, idos e, arabinose, xylose, lyxose, ribose and alkoxylated derivatives thereof; and x is 1 to 30; (b) an aspartate component B comprising at least one polymerisation product of aspartic acid, optionally in form of a copolymerisate with fatty acids, polybasic carboxylic acids, anhydrides of polybasic carboxylic acids, polybasic hydroxycarboxylic acids, monobasic polyhydroxycarboxylic acids, alkoxylated alcohols, alkoxylated amines, amino sugars, carbohydrates, sugar carboxylic acids and polymers thereof. The invention further relates to the use of such chemical compositions as corrosion inhibtor.

Abstract: Use of water-soluble alkane sulfonic acid (I) for increasing the permeability of underground carbonates (A) and/or carbonates containing petroleum and/or for forming natural gas-prominent rock. An independent claim is included for: a procedure to increase the permeability of underground, carbonate and/or carbonate containing petroleum and/or to form natural gas-prominent rock; and/or to dissolve carbonate and/or carbonate containing impurities in petroleum production, comprising: forming an acid formulation (comprising alkane sulfonic acid or aqueous alkane sulfonic acid) by at least drilling into the rock formation on pressing.
