Abstract: Disclosed are compositions and methods for the pressure protection of existing wells during infill drilling operations. The methods can include injecting a foamed pressure protection composition into the existing wellbore in fluid communication with an unconventional subterranean formation prior to and/or during fracturing of the new wellbore in fluid communication with the unconventional subterranean formation.
