Abstract
The present invention relates to emulsion stabilizing agents, to subterranean treatments fluids comprising said emulsion stabilizing agents and to a method of treating subterranean formations using said subterranean treatments fluids. These emulsion stabilizing agents, besides having excellent emulsifying properties, do not cause the swelling and dispersion of clays and are able to provide subterranean treatments fluids with excellent rheological behaviour even at high temperatures.
