摘要： 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.

摘要： The invention provides an apparatus and method for perforating and treating multiple intervals of one or more subterranean formations intersected by a wellbore by deploying a bottom-hole assembly (“BHA”) having a perforating device and at least one sealing mechanism within said wellbore. The BHA may be deployed in the wellbore using a tubing string or cable; or alternatively, the BHA may be deployed using a tractor system attached directly to the BHA. The perforating device is used to perforate the first interval to be treated. Then 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 first interval to be treated. A treating fluid is then pumped down the wellbore and into the perforations created in the perforated interval. The sealing mechanism is released, and the steps are then repeated for as many intervals as desired, without removing the BHA from said wellbore.

摘要： 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 a bottom-hole assembly (“BHA”) having a perforating device and a sealing mechanism within said wellbore. In one embodiment, the perforating device has no washing fluid flow passage provided therethrough. In another embodiment, an erosive jet device is used to perforate at least one interval of said one or more subterranean formations. In yet another embodiment, the BHA has at least one pressure equalization means that establishes pressure communication between the portions of the wellbore above and below the sealing mechanism. In another embodiment, the BHA comprises a perforating device and a sealing mechanism, wherein the perforating device is positioned below the sealing mechanism. In one embodiment, the BHA is deployed in the wellbore and the perforating device is used to perforate an interval to be treated. 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.

摘要： A perforating gun assembly for use in perforating multiple intervals of at least one subterranean formation intersected by a cased wellbore and in treating the multiple intervals using a diversion agent, such as ball sealers. In one embodiment, the apparatus of the present invention comprises a perforating assembly having a plurality of select-fire perforating devices interconnected by connector subs, with each of the perforating devices having multiple perforating charges. The apparatus also includes at least one decentralizer, attached to at least one of the perforating devices, which is adapted to eccentrically position the perforating assembly within the cased wellbore so as to create sufficient ball sealer clearance between the perforating assembly and the inner wall of the cased wellbore to permit passage of at least one ball sealer.
