Abstract: Described herein is a novel method of strengthening a wellbore wherein the method uses a polyurea silicate composition. In the method of strengthening an oil well, a gas well or a water well, a mixture comprising at least one isocyanate component having at least two isocyanate groups per molecule; at least one alkali metal silicate; and water is pumped through the oil well, the gas well or the water well into the annulus of the well; subsequently, the mixture is allowed to form a polyurea silicate composition; before the polyurea silicate composition sets to thereby give a polyurea matrix comprising domains of silicate.

Abstract: Described herein are methods for manufacturing a concentrate enriched in iron mineral content from an ore, which contains an iron mineral and silicate, by a reverse flotation. The method includes adding a first amine to a prepared aqueous pulp of the ore and optionally one or more flotation auxiliaries to obtain an aqueous mixture. The first amine (A) may be a compound of formula Ia salt of a protonated compound of formula I and a first anion or a mixture thereof. A second amine, which is a compound of formula IIa salt of a protonated compound of formula II and a second anion or a mixture thereof, can be further added. Further described herein are specific compositions of the first amine (A) and the second amine (B) for a use as a flotation collector.

Abstract: The invention relates to a method for the preparation of a hyperbranched polyester mixture obtainable by reacting a hydroxyl group containing carboxylic acid (B) with at least one carboxylic acid group and at least two hydroxyl groups with a diol (C) having a molecular weight of more than 100 g/mol, optionally in the presence of at least one further reactant, wherein the at least one further reactant is a polyol (A) having at least three hydroxyl groups under a reaction condition allowing ester and ether formation; and reacting the mixture resulting from step (a) with a hydrophobic carboxylic acid (D) resulting in the hyperbranched polyester mixture. The invention further relates to said hyperbranched polyester mixture and the use as wax inhibitor, as pour point depressant, as lubricant or in lubricating oils.

Abstract: Se describe en la presente un método novedoso para fortalecer una perforación de pozo, en donde el método utiliza una composición de silicato de poliurea. En el método para fortalecer un pozo de petróleo, un pozo de gas o un pozo de agua, una mezcla que comprende por lo menos un componente de isocianato que tiene por lo menos dos grupos isocianato por molécula; por lo menos un silicato de metal alcalino y agua se bombea a través del pozo de petróleo, el pozo de gas o el pozo de agua en el anillo del pozo; y subsecuentemente, la mezcla se deja formar una composición de silicato de poliurea; antes de que la composición de silicato de poliurea se endurezca para de esta manera dar una matriz de poliurea que comprende dominios de silicato.
