Abstract
This invention relates to the field of techniques for treating subterranean formations with gels during an oil or gas exploration or production operation, i.e., during drilling, completion, or hydraulic fracking processes. The invention relates in particular to a system making it possible to limit or even inhibit the phenomena known as loss of fluids (wager and/or gas) in an underground formation, particularly in a zone where the temperature is high.More particularly, the invention relates to a suspension (S) comprising:
