Abstract: A plugging fluid for plugging a subterranean formation zone surrounding a drill hole comprises an emulsion comprising a dispersed aqueous phase containing an aqueous base and a continuous hydrophobic phase containing a polymer consisting of a grafted cellulose ether derivative, a surfactant and a crosslinking activator of the polymer. The polymer is preferably 2-hydroxyethyl cellulose grafted with vinyl phosphonic acid. Upon shearing, preferably through the drilling bit, the emulsion inverts so that the rupture of the emulsion droplets releases the crosslinking activator into the water phase thus forming a gel structure.

Abstract: A method for preparing a plugging liquid for plugging of a zone of a subterranean formation around a bore hole, consisting of an emulsion comprising a continuous phase based on a hydrophobic liquid and a discontinuous phase based on a hydrophilic liquid, which emulsion contains an emulsifier, a polysaccharide and a cross-linking agent for said polysaccharide. The emulsifier, the polysaccharide and the cross-linking agent for the polysaccharide are introduced into and mixed with the hydrophobic liquid in any desired sequence, whereby a mixture is obtained which is stable for an extended period of time and which, if desired, can be transported as such from one place to another, e.g. from a land based mixing station to an offshore oilrig or similar. The hydrophilic liquid, usually water, is then introduced gradually into the prepared mixture under agitation, whereby the emulsion is formed. The invention also relates to said mixture which is obtained as an intermediary product.
