Baker Hughes Incorporated - Houston TX

International Classification:

E21B 43/116

US Classification:

166297, 166298, 89 115, 102310

Abstract:

A perforating system having a perforating gun with a pressurizable gun body. The gun body can be pressurized prior to deployment in a wellbore, or while in the wellbore.

Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

E21B 33/12

US Classification:

166387, 166118, 166196

Abstract:

Disclosed herein are sealing assemblies which include a mandrel; an inner element formed around the mandrel; an outer element formed around the inner element; and a plurality of slats arranged between the inner and outer elements. The slats have a friction-reducing agent on the surface of the slats. Also disclosed herein are methods for zonal isolation within a wellbore. The methods include providing a mandrel; providing an inner element formed around the mandrel; providing an outer element formed around the inner element; providing a plurality of slats arranged between the inner and outer elements; and axially compressing the inner element and the outer element to radially expand the inner element and outer element. The slats have a friction-reducing agent on their surface.

International Classification:

E21B 43/11

US Classification:

166297, 166 55, 102312

Abstract:

A shaped charge assembly for use in a perforating gun that further comprises a charge carrier, and gun housing. The charge carrier substantially encapsulates the closed portion of the shaped charge and extends from the outer periphery of the shaped charge to the inner diameter of the associated gun housing. Encapsulating the shaped charge substantially reduces the introduction of debris into the wellbore resulting from detonation of the perforating gun shaped charges. The charge carrier can include a multiplicity of shaped charges therein.

International Classification:

E21B 7/00

US Classification:

175004600

Abstract:

A shaped charge assembly for use in a perforating gun that comprises a shaped charge holder, two or more shaped charges, slots formed to receive the shaped charges, and an impedance barrier disposed between adjacent shaped charges. The impedance barrier can comprise a gap formed in the shaped charge holder, where the impedance barrier runs across the shaped charge holder. The impedance barrier can be a void formed on the surface of the shaped charge holder, or can include shock attenuating material therein, such as wood, cork, cotton, polymeric materials, and combinations thereof, to name a few.

H01R 13/62

US Classification:

166297, 166 551, 166 55, 439312

Abstract:

A perforating system having annular connectors for attachment between adjacent perforating guns and connectors. The connectors include male and female connectors with respective outer and inner contact surfaces. The connectors also include attachment for electrical detonators and/or booster charges for transferring ballistic detonations between the perforating gun and connector sub.

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 43/11
E21B 43/00

US Classification:

166297, 166 55, 166 651

Abstract:

A cartridge assembly for use with a perforating system having a contact terminal that connects to a perforating signal line when inserted into a receptacle end of a perforating gun. A detonator may be included in an end of the cartridge assembly for initiating a detonating cord in the perforating gun. The cartridge assembly is a modular unit that replaces the manual connections made when assembling a string of perforating guns. The cartridge assembly may optionally include a controller switch for controlling current flow through the cartridge assembly.

International Classification:

E21B 34/16
E21B 34/06
E21B 34/00

US Classification:

166373, 1663324, 1663328

Abstract:

A safety valve for subsurface disposal equipped with an interfacing element of elastomeric and non-elastomeric components. The components include an elastomeric energizing component and a non-elastomeric seal ring configured to work together in attaining an internal seal sufficient for allowing the valve to remain consistently closed. Indeed, the aid afforded by the interfacing element may allow the valve to remain consistently and effectively closed even in particularly low pressure well environments or those of widely varying temperatures.

International Classification:

E21B 34/06

US Classification:

166373, 166319

Abstract:

An actuating method includes applying an input pressure to a first side of a tool operator and to a second side of the tool operator and moving the tool operator from a first position to a second position in response to depleting the input pressure applied to the second side. A state of a tool element can be changed in response to moving the tool operator from the first position to the second position. The input pressure may be depleted from the second side of the tool operator by transferring hydraulic fluid to a confined diameter container disposed in an annular region of the actuating device or to the first side of the tool operator.
