The invention discloses methods of, as well as apparatus and systems for,
perforating and treating multiple intervals of one or more subterranean
formations intersected by a wellbore by deploying within said wellbore a
bottom-hole assembly ("BHA") having a perforating device and a sealing
mechanism, wherein pressure communication is established between the
portions of the wellbore above and below the sealing mechanism. The BHA
is positioned within the wellbore such that the sealing mechanism, when
actuated, establishes a hydraulic seal in the wellbore to positively
force fluid to enter the perforations corresponding to the interval to be
treated. A treating fluid is pumped down the wellbore and into the
perforations created in the perforated interval. The sealing mechanism is
released, and the steps are repeated for as many intervals as desired,
without having to remove the BHA from said wellbore.
