Appl. No.:

09/764699

Inventors:

James Marshall Barker - Mansfield TX

Assignee:

Halliburton Energy Services, Inc. - Dallas TX

International Classification:

F42B 3900

US Classification:

206 3, 206593, 53446

Abstract:

A system and method for packaging shaped charges ( ) for transportation is disclosed. Each shaped charge ( ) includes a housing ( ) and a liner ( ) having a high explosive disposed therebetween. A jet spoiler ( ) is positioned proximate the liner ( ) of each of the shaped charges ( ) to prevent the formation of a jet in the event of an inadvertent initiation of a shaped charge ( ). The shaped charges ( ) are then oriented in first and second layers such that the jet spoilers ( ) positioned proximate the liners ( ) of the shaped charges ( ) in the first and second layers oppose one another. A shielding panel ( ) is disposed between the shaped charges ( ) of the first and second layers. The shaped charges ( ) including the jet spoilers ( ) and the shielding panel ( ) are placed within an expandable bag ( ) which is in turn enclosed within a transportation container ( ).

Assignee:

Halliburton Energy Services, Inc. - Dallas TX

International Classification:

E21B 43116

US Classification:

166297, 166382, 166 552

Abstract:

Apparatus and associated methods of using the apparatus are disclosed for performing cuts in a subterranean well. The apparatus utilizes linear shaped charges arranged in an endless pattern which are used to cut a pattern in a downhole structure. The charges are discharged to perform the cutting operation.

Assignee:

Halliburton Energy Services, Inc. - Dallas TX

International Classification:

E21B 43119

US Classification:

89 115, 177 455

Abstract:

A unique phasing pattern is provided that maximizes the effective perforation geometry of a wellbore. The improvement overcomes the problems associated with multi-phase guns of the past that failed to account for the fact that the gun rested on the low side of the casing. In one embodiment of the present invention, the phasing is arranged so that there is a zero phase tunnel formed. The zero phase tunnel is located at approximately the location where the gun rests against the low side of the well. Further, tunnels are formed by shape charges at plus and minus forty-five degrees and at plus and minus ninety degrees. This can also be referred to as a penta-phase. In another embodiment of the invention, charges can also be placed to allow for a plus and minus one hundred and thirty-five degrees pattern in addition to the penta-phase pattern described above. This expanded pattern can also be referred to as a hepta-phase pattern. By improving the phasing pattern of the perforation gun, valuable hydrocarbon fluids will encounter less resistance to flow into the well.

International Classification:

E21B 43/11

US Classification:

166297, 166 551, 175 46, 89 115, 102320

Abstract:

A system and method for making and using a multi-point initiation explosive device that produces an enhanced pressure wave for severing tubing, pipe or casing in an oil or gas well. At least two opposed initiators initiate a column of explosive material from opposite ends, thereby generating opposing pressure waves propagating toward a midpoint between the initial initiators. A shaped-charge assembly with a liner located at the midpoint initiates immediately prior to the arrival of the opposing pressure waves and forms a fast moving jet to pre-score the target pipe prior to the arrival of the pressure pulse propagating from the initial detonations.

Abstract:

A perforating gun assembly () for creating communication paths for fluid between a formation () and a cased wellbore () includes a housing, a detonator and a detonating cord (). The perforating gun assembly () includes one or more substantially axially oriented collections of shaped charges () each of which is operably associated with the detonating cord (). A perforation () is formed in the formation () as a result of the interaction of jets () formed upon the detonation of at least two shaped charges () that create a weakened region () in the formation () followed by the detonation of at least one shaped charge () that forms a jet () that penetrated through the weakened region ().

Abstract:

A perforating gun assembly () for creating communication paths for fluid between a formation () and a cased wellbore () includes a housing (), a detonator () positioned within the housing () and a detonating cord () operably associated with the detonator (). The perforating gun assembly () also includes one or more substantially axially oriented collections () of shaped charges. Each of the shaped charges in the collections () is operably associated with the detonating cord (). In addition, adjacent shaped charges in each collection () of shaped charges are oriented to converge toward one another such that upon detonation, the shaped charges in each collection () form jets that interact with one another to create perforation cavities in the formation ().
