Zusammenfassung:	Compositions, methods, and systems including an encapsulated additive comprising a treatment fluid additive at least partially encapsulated by an encapsulating material. The encapsulated additive has a target release profile for release of the treatment fluid additive from the encapsulating material in a specific wellbore environment. The encapsulating material is selected to achieve the target release profile, the target release profile being based on one or more conditions selected from the group consisting of: (1) a target anisotropic pressure that is greater than both an injection anisotropic pressure and an injection isotropic pressure, (2) an erosion number, (3) a temperature-driven degradation, (4) a pressure-driven degradation, (5) an amphiphilic water dispersibility, (6) an amphiphilic oil dispersibility, (7) a chemical flood degradation, (8) a water ingress value, and, (9) a radiation-driven degradation.
