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.

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 (nullBHAnull) 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 method and apparatus for improving reservoir communication includes, in one arrangement, use of one or more chambers to create an underbalance condition and/or a fluid surge in the wellbore. In another arrangement, a tool string comprises a packer, a circulating valve, and an atmospheric chamber, in which the circulating valve, when open, is adapted to vent a lower wellbore region below the packer when the packer is set, and the atmospheric chamber is capable of being operated to create an underbalance condition below the packer. In yet another arrangement, an apparatus comprises a subsea wellhead equipment including a blow-out preventer, choke line filled with a low density fluid, and a kill line filled with a heavy fluid. The choke line is adapted to be opened to create an underbalance condition in the wellbore. In yet another arrangement, a method of creating an underbalance condition comprises controlling wellbore pressure at least in a perforating interval to achieve a target level, configuring a perforating gun to achieve a target detonation pressure in the perforating gun upon detonation, and creating an underbalance condition in the perforating interval of the wellbore when the perforating gun is shot. In yet another arrangement, a tool string for use in a wellbore extending from a well surface comprises a closure member adapted to be positioned below the well surface, and a chamber defined at least in part by the closure member. The tool string further comprises at least a port selectively openable to enable communication between the chamber and a wellbore region. The port when open creates a fluid surging to the chamber to provide a low pressure condition in the wellbore region. A tool in the tool string is adapted to perform an operation in the low pressure condition.

摘要： The present invention provides a method and apparatus for plugging a wellbore in a trip saving manner. In one aspect, the invention includes a cement retainer disposed on a run-in string and a radially expanded perforating assembly disposed below the cement retainer. In a single run, the apparatus provides for perforating a wellbore and squeezing cement through the perforations and into the formation therearound. In another aspect, a method of plugging the wellbore includes running a cement retainer and a radially expanded perforating assembly into a wellbore on a run-in string. After the cement retainer is set, a firing head is actuated to cause the perforating gun to discharge. After perforations are formed, cement is introduced from the cement retainer into the isolated area and squeezed through the perforations. Thereafter, the run-in string disengages from the cement retainer leaving behind the plug formed. In yet another aspect, a firing head capable of being actuated by different means is used to discharge the perforating assembly.

摘要： A detonation transfer subassembly for coupling two detonation activated tools in a work sting such that the work string may be severed between the two detonation activated tools without risk of a detonation is disclosed. The detonation transfer subassembly comprises first and second explosive carrying members having a detonation transfer member disposed therebetween. The detonation transfer member defines a longitudinal passageway therein. A firing pin is disposed within the longitudinal passageway. The firing pin has a first position proximate the first explosive carrying member and a second position proximate the second explosive carrying member. The firing pin is propellable from the first position to the second position following a detonation within the first explosive carrying member such that the firing pin impacts an explosive disposed within the second explosive carrying member, thereby transferring detonation from the first explosive carrying member to the second explosive carrying member.
