Abstract
The present invention relates to compositions and methods for reducing or preventing the loss of drilling fluids and other well servicing fluids into a subterranean formation during drilling or construction of boreholes in said formation. Specifically, this invention comprises a curable composition capable of free radical polymerization for creating lost circulation material in-situ. The curable composition comprises an organic compound capable of free radical (co)polymerization represented by the formula (I): wherein x is an integer from 1 to 8; Fp comprises one or more moiety comprising a free radical polymerizable group; L is an organic moiety comprising a (substituted) aromatic or (substituted) aliphatic group comprising one or more O, N, S, or combinations thereof; and Q comprises a substituted or unsubstituted mono- or polyvalent organic radical comprising one or one or more moiety selected from alkyl, alkylene, alkenyl, cycloalkyl, cycloalkylene, aryl, aralkyl, alkaryl, poly(oxyalkylene), poly(carboalkoxyalkylene), a substituted heterocyclic radical, or an unsubstituted heterocyclic radical.
