Abstract
Hydroxyacetic acid condensation product is used as a fluid loss material in a formation fracturing process in which a fracturing fluid comprising a hydrolyzable aqueous gel is used. The hydroxyacetic acid condensation product degrades at formation conditions to provide hydroxyacetic acid which breaks the aqueous gel, which provides restored formation permeability without the need for separate addition of gel breaker.
