ABSTRACT:
Apparatus and associated methods for performing operations within a subterranean well overcome many disadvantages associated with perforating and fracturing and/or gravel packing in a single trip of a work string into the well. In a preferred embodiment, a method of producing fluids from a formation intersected by the well includes the step of setting a packer having a relatively large seal bore formed therethrough in the well before running the work string into the well. After the formation is perforated, the work string is displaced to position a seal assembly on the work string in the seal bore, thereby displacing the perforating guns through the packer, positioning a screen opposite the perforated formation, and enabling performance of gravel packing operations thereafter.
