Methods for inhibiting scale formation in a hydrocarbon well

A method of inhibiting scale formation in a hydrocarbon well that extends within a subterranean formation, the method comprising:

• locating a selective-release scale inhibitor within a portion of the subterranean formation, wherein the selective-release scale inhibitor is configured to be at least substantially insoluble in hydrocarbons;
• producing a reservoir fluid from the subterranean formation via the hydrocarbon well;
• and
• facilitating a change in environmental conditions present within the portion of the subterranean formation from initial environmental conditions, in which the selective-release scale inhibitor is at least substantially insoluble in water, to subsequent environmental conditions, in which the selective-release scale inhibitor is soluble in water, wherein the facilitating includes initiating dissolution of the selective-release scale inhibitor responsive to fluid contact between the selective-release scale inhibitor and water at the subsequent environmental conditions;
• wherein the selective-release scale inhibitor is a first selective-release scale inhibitor, and further wherein the method includes locating a second selective-release scale inhibitor within the portion of the subterranean formation, wherein dissolution of the second selective-release scale inhibitor in water suppresses dissolution of the first selective-release scale inhibitor within water.
