The filtercake is preferably formed while drilling a subterranean formation using a drilling fluid includes: an oleaginous fluid; a nono-leaginous fluid; an amine surfactant having the structure: wherein R is a C 12 -C 22 aliphatic hydrocarbon; R' is an independently selectable from hydrogen or C 1 to C 3 alkyl; A is NH or O, and 1 ≤ x+y ≤ 3. In the method, the filter cake is exposed to a delayed phase changing agent selected from the group consisting of aliphatic amine acids, salts of aliphatic amine acids and combinations thereof. In one preferred illustrative embodiment, the delayed phase changing agent is delivered in the form of a pill, the pill including a carrier fluid, a viscosifier and the delayed phase changing agent. The delayed phase changing agent may be selected from ethylene diamine tetraacetic acid, alkali metal salts of ethylene diamine tetraacetic acid and combinations of these and similar compounds.
