US Patent:

20210355797, Nov 18, 2021

Filed:

May 18, 2020

Appl. No.:

16/877386

Inventors:

- Houston TX, US
Richard Ellis ROBEY - Mansfield TX, US
Christopher C. HOELSCHER - Arlington TX, US
Joseph T. MACGILLIVRAY - Fort Worth TX, US

International Classification:

E21B 43/119
E21B 17/042
E21B 43/116

Abstract:

The disclosed embodiments include bulkheads for perforating guns and perforating gun assemblies. A bulkhead includes a threadless exterior surface that spans a length of a threaded connection of adjacent first and second perforating guns. The bulkhead also includes a first exterior groove having a first sealing element partially disposed in the first exterior groove. The bulkhead further includes a second exterior groove having a second sealing element partially disposed in the second exterior groove, where the first sealing element and the second sealing element are positioned around the threaded connection.

Christopher C. Hoelscher - Arlington TX, US

International Classification:

E21B 43/116

Abstract:

An apparatus and method according to which a perforating gun includes a volume fill body. The volume fill body is positioned in the space between a charge tube and a carrier tube. The fill body occupies at least part, and sometimes all, of the free volume space between the charge tube and carrier tube thereby reducing the free volume space. In certain downhole applications, large free volume space can lead to significant reductions in wellbore pressure, causing dynamic underbalance, which is undesirable. The presence of the volume fill body prevents, or at least reduces, dynamic underbalance and its effects. Also, the volume fill body aligns the charge tube with the carrier tube, further assisting perforation.

Assignee:

Halliburton Energy Services, Inc. - Houston TX

International Classification:

E21B 43/119
E21B 43/116

Abstract:

A perforating system and method includes a perforating gun with shaped charges and an orientation device. The orientation device provides an orientation datum. Sensors associated with the perforating gun detect relative alignment of each perforating gun as compared to the orientation datum. A detonation signal can be either sent or not sent to the perforating gun in response to the signal received from the orientation sensor.

Appl. No.:

16/908053

Inventors:

- Houston TX, US
Richard Ellis Robey - Mansfield TX, US

International Classification:

E21B 43/117

Abstract:

A perforating tool assembly may be modularized by providing modular charge segments to provide for multiple configurations of shaped charges without the requirement of excess inventory. The modular charge segments may comprise any number of modular charge holder segments and modular charge spacer segments which are configured to provide for different spacings and offsets of shaped charges disposed within the modular charge holder segments. The modular charge holder segments include slots and locking tabs to allow for the differing offsets between charges. The modular charge holder segments may comprise a slit that allows the modular holder segment to be flexed or deflected to permit the loading and downloading of shaped charges. The modular charge segments may comprise a plastic or rubber material to provide for safer deployment of shaped charges downhole.

International Classification:

E21B 43/119
E21B 43/117

Abstract:

This disclosure may generally relate to subterranean operations. A ballistic transfer apparatus may include a detonation transfer line, wherein the detonation transfer line comprises a first end and a second end; a first holder in engagement with the first end of the detonation transfer line to retain the detonation transfer line in the ballistic transfer apparatus; a second holder in engagement with the second end of the detonation transfer line to retain the detonation transfer line in the ballistic transfer apparatus; and a shroud extending between the first holder and the second holder that covers the detonation transfer line.

Inventors:

- Houston TX, US
Richard Ellis Robey - Mansfield TX, US

International Classification:

E21B 43/119
E21B 43/117

Abstract:

An apparatus comprises a first cluster of perforator guns positioned circumferentially around a central longitudinal axis at a first axial position, wherein the first cluster is configured in a closed position while the apparatus is being lowered to a perforator position in a wellbore. After the apparatus is lowered to the perforator position, the first cluster is to move to an expanded position such that the perforator guns are moved closer to a target that is to be perforated.
