ABSTRACT:
A system for completing a well having casing (34) includes a perforating assembly (38) and a tubing string assembly (40). The tubing string assembly (40) including a pair of seal assemblies (56, 74), a production screen assembly (58) and a ported sleeve (66) positioned between the seal assemblies (56, 74) and a live annulus screen assembly (76) positioned uphole of the seal assemblies (56, 74). The perforating assembly (38) is operated to perforate the well and is then released downhole. The tubing string assembly (40) is then repositioned such that the production screen assembly (58) is located proximate the perforated interval (14) so that when the well is hydraulically fractured with a treatment slurry that is pumped through the ported sleeve (66), the formation reaction to the fracturing is monitored by obtaining pressure readings in the annulus in fluid communication with the live annulus screen assembly (76).
