| Zusammenfassung: | A fluid for the drilling, workover or completion of a subterranean well comprises an aqueous base, the browning reaction product of a carbohydrate, and a cation. Browning polymers may be formed by application of heat to an alkaline solution of the carbohydrate and the browning reaction product may be reacted with a cationic base. Inversion of non- reducing sugars may be first effected on selected carbohydrates with the inversion catalysing the browning reaction. |
