Abstract
Methods, computer programs, and systems for evaluating and treating previously-fractured subterranean formations are provided. An example method includes, for one or more of the one or more layers, determining whether there are one or more existing fractures in the layer. The method further includes, for one or more of the one or more existing fractures, measuring one or more parameters of the existing fracture and determining conductivity damage to the existing fracture, based, at least in part, on one or more of the one or more measured parameters of the existing fracture. The method further includes selecting one or more remediative actions for the existing fracture, based, at least in part, on the conductivity damage.
