Abstract
Methods and devices useful in subterranean treatment operations are provided. One example of a device is a dart having a deformable body, a nosepiece connected to a lower terminus of the deformable body, and a channel extending through the deformable body and the nosepiece. One example of a method includes providing a dart, providing a production casing having at least one production sleeve therein, placing the dart in the production casing of a well bore, pumping a treatment fluid into the well bore, and allowing the dart to open the production sleeve within the production casing such that the treatment fluid is introduced into the subterranean formation through the production casing.
