  • METHOD TO USE LOSS CIRCULATION MATERIAL COMPOSITION COMPRISING ALKALINE NANOPARTICLE-BASED DISPERSION AND FORMATE ACTIVATOR IN DOWNHOLE CONDITIONS
    Publication number: 20250059092
    Abstract: A loss circulation material (LCM) includes an alkaline nanosilica dispersion and a formate activator. The formate activator may be present in an amount in a range of 1 wt % to 40 wt % of the loss circulation material. A method of controlling loss circulation in a loss circulation zone (LCZ) in a wellbore includes introducing an alkaline nanosilica dispersion into the wellbore, introducing a formate activator solution into the wellbore, contacting the alkaline nanosilica dispersion with the formate activator, thereby forming a LCM composition, and forming a gelled solid from the LCM in the loss circulation zone. A method of controlling loss circulation in a LCZ in a wellbore includes introducing a LCM that includes an alkaline nanosilica dispersion and a formate activator into the wellbore such that they contact the LCZ, and forming a gelled solid from the LCM in the LCZ.
