Abstract: A lost circulation material (LCM) is provided having an alkaline nanosilica dispersion, a polyester activator, and a formaldehyde resin. The alkaline nanosilica dispersion and the polyester activator may form a gelled solid after interaction over a contact period, such that the gelled solid incorporates the formaldehyde resin. Methods of lost circulation control using the LCM are also provided.

Abstract: A downhole system includes a packer sealing an annular space around a downhole tubing and an insulating packer fluid positioned within the annular space and adjacent to the packer. The insulating packer fluid includes a sodium bicarbonate activator and an acidic nanosilica dispersion having silica nanoparticles and a stabilizer, wherein the pH of the acidic nanosilica dispersion ranges from 2 to 5, and the silica nanoparticles form at least 20 percent by weight of the acidic nanosilica dispersion.
