Abstract
Methods are provided which permit pressure tested multiple perforating gun modules to be interconnected into gun assemblies, without disturbing any pressure-bearing seals of the modules. Prior to assembling the gun assembly, the seals of the modules are pressure tested. The pressure tested modules are then connected to each other without disconnecting or otherwise breaking any of the pressure-bearing seals of the modules.
Claims22
A method for preparing a perforating gun assembly for insertion into and use in a wellbore, the assembly comprising at least a first and a second perforating gun module, each of the modules having a first and a second end, the method comprising:
- creating each perforating gun module by taking a perforating gun section that has a first and a second end, and operably attaching a first pressure test connector to the first end of the perforating gun section and operably attaching a second pressure test connector to the second end of the perforating gun section, whereby when the pressure test connectors are operably attached to each end of the perforating gun section, the pressure test connectors are capable of holding sufficient pressure for pressure testing of the complete perforating gun module;
- pressure testing each of the perforating gun modules;
- and
- then connecting the perforating gun modules together by operably connecting one of the pressure test connectors on the first perforating gun module to one of the pressure test connectors on the second perforating gun module, without breaking any pressure-bearing seal of the gun modules between the pressure testing step and the connecting step.
A method for preparing a perforating gun module for insertion into and use in a wellbore, the method comprising:
- creating a perforating gun module by taking a perforating gun section that has a first and a second end, and operably attaching a first pressure test connector to the first end of the perforating gun section and operably attaching a second pressure test connector to the second end of the perforating gun section, whereby when the pressure test connectors are operably attached to each end of the perforating gun section, the pressure test connectors are capable of holding sufficient pressure for pressure testing of the complete perforating gun module;
- pressure testing the perforating gun module;
- and
- then inserting and using the perforating gun module in the wellbore without removing the pressure test connectors between the pressure testing step and the inserting step.
A method for preparing a spacer module for insertion into and use in a wellbore, the method comprising:
- creating the spacer module by taking a spacer section that has a first and a second end, and operably attaching a first pressure test connector to the first end of the spacer section and operably attaching a second pressure test connector to the second end of the spacer section, whereby when the pressure test connectors are operably attached to each end of the spacer section, the pressure test connectors are capable of holding sufficient pressure for pressure testing of the complete spacer module;
- pressure testing the spacer module;
- and
- then inserting and using the spacer module in the wellbore without removing the pressure test connectors between the pressure testing step and the inserting step.
A method of delivering a pressure tested explosive assembly into a wellbore, the method comprising the steps of:
- providing the assembly including multiple individual explosive modules, each of the modules including at least one pressure-bearing seal;
- pressure testing each of the modules;
- and
- then interconnecting the modules to each other to thereby form the assembly, without breaking any of the pressure bearing seals of the modules between the pressure testing step and the interconnecting step.
A method of delivering a pressure tested explosive assembly into a wellbore at a wellsite, the method comprising the steps of:
- pressure testing multiple explosive modules of the assembly at a location remote from the wellsite;
- transporting the pressure tested modules to the wellsite;
- then interconnecting the modules to form the assembly;
- and
- then installing the assembly in the wellbore, without breaking any pressure bearing seal of any of the modules between the pressure testing step and the installing step.
A method of delivering a pressure tested explosive assembly into a wellbore at a wellsite, the method comprising the steps of:
- pressure testing multiple explosive modules of the assembly at a location remote from the wellsite, each of the modules having at least one pressure test connection attached thereto during the pressure testing step;
- transporting the pressure tested modules to the wellsite;
- then interconnecting the modules to form the assembly, without removing the pressure test connections from the modules;
- and
- then installing the assembly in the wellbore.
