Abstract
Devices and methods for deploying perforating guns through a wellhead production assembly and into a wellbore. In particular embodiments, the invention provides devices and methods for deploying multiple perforating guns through a wellhead production assembly. In the event that the perforating gun assembly is dropped into the wellhead production assembly, a safety clamp will land upon a landing profile within a deployment riser, preventing the perforating gun assembly from falling into the wellbore.
Claims17
A method of deploying a perforating gun assembly into a wellhead production assembly comprising the steps of:
- securing a first safety clamp to a first perforating gun;
- hanging the first perforating gun within the wellhead production assembly by resting the first safety clamp on a support surface;
- securing a second perforating gun to the first perforating gun to form a perforating gun assembly;
- securing a second safety clamp to the second perforating gun;
- removing the first safety clamp;
- and
- lowering the perforating gun assembly into the wellhead production assembly to rest the second safety clamp on the support surface.
A method of deploying a perforating gun assembly into a wellhead production assembly comprising the steps of:
- disposing a no-go landing shoulder within the wellhead production assembly that is shaped and sized to engage a safety clamp in the event that the perforating gun assembly is dropped into the wellhead production assembly;
- securing a first safety clamp to a first perforating gun;
- hanging the first perforating gun within the wellhead production assembly by resting the first safety clamp on a support surface;
- securing a second perforating gun to the first perforating gun to form a perforating gun assembly;
- securing a second safety clamp to the second perforating gun;
- removing the first safety clamp;
- and
- lowering the perforating gun assembly into the wellhead production assembly to rest the second safety clamp on the support surface.
