Abstract: A method of synthesizing sodium formate. The method includes reacting acetaldehyde, formaldehyde, and NaOH to form a raw reaction solution which includes pentaerythritol and sodium formate. The method also includes passing the raw reaction solution to an evaporator to reduce the water content of the raw reaction solution and remove any unreacted formaldehyde from the raw reaction solution to form a concentrated reaction solution and cooling the concentrated reaction solution to form pentaerythritol crystals in suspension while retaining sodium formate in solution. Further, the method includes filtering the cooled concentrated reaction solution to remove the pentaerythritol crystals and create a mother liquor comprising the sodium formate in solution and separating the sodium formate from the mother liquor.

Abstract: A method for plugging and sealing subsurface formations using alkaline nanosilica dispersion and a delayed activation chemistry is disclosed. In accordance with one embodiment of the present disclosure, the method includes introducing a mixture with a first pH into the subsurface formation. The mixture comprises an aqueous solution, an alkaline nanosilica dispersion and a water-soluble hydrolyzable compound. The method further includes allowing the water-soluble hydrolyzable compound to hydrolyze in the subsurface formation to form an acid at 70° C. or greater, thereby acidizing the mixture to a reduced second pH and causing the alkaline nanosilica dispersion to gel into a solid and seal the subsurface formation. A composition for sealing a subsurface formation is also disclosed. The composition includes an aqueous mixture including water, an alkaline nanosilica dispersion, and a water-soluble hydrolyzable compound.
