WELL TREATMENT FLUID HAVING A DISPERSION BASED ON ACIDIC NANOPARTICLES AND A POLYAMINE |
| abstract |
A lost circulation material (LCM) comprising an acidic nanosilicate dispersion and a polyamine-type activator. The acidic nanosilicate dispersion and the polyamine-based activator can form a gelled solid after interaction during a contact period. The invention also relates to methods of controlling circulation loss using LCM. The present invention relates to a well treatment fluid containing an acidic nanosilicate dispersion and a polyamine activator. The acidic nanosilicate dispersion and the polyamine activator can form a gelled solid after interaction for a period of time. The invention also relates to methods of reducing water production using well treatment fluids. |
