  • Publication number: 20200337575
    Abstract: Methods and systems for conditioning a signal indicative of electrosurgical unit activity are described. A hardware circuit acquires AC current from an electrosurgical unit on patient isolated circuitry and conditions the signal in either of two alternate processing methods. The processed signal is routed as input to an analog to digital converter circuit. A method for determining saturation on referential inputs and recovering inputs to an unsaturated state is also described.

  • Publication number: 20200102814
    Abstract: Embodiments of the present disclosure include a method for fabricating a perforating gun including forming an expendable hollow carrier (EHC) via a drawing process. The method also includes determining a wall thickness of the EHC is above a threshold. The method includes machining a coupling component to at least one end of the EHC. The method further includes installing perforating components within an interior of the EHC.

  • Patent number: 10422204
    Abstract: A system and method for stimulating hydrocarbon production from a wellbore that perforates the formation around the wellbore in strategic locations so that fractures can be formed in the formation having specific orientations. The system includes deep penetration perforators that extend past a portion of the formation adjacent the wellbore having locally high internal stresses (a stress cage); and big hole perforators that form perforations with a larger entrance diameter. The perforators form perforations in the formation that are axially consolidated along the wellbore. After perforating, the wellbore is hydraulically fractured with high pressure fluid, which creates fractures in a formation surrounding the wellbore that extend radially outward from the perforations. Creating perforations that are axially consolidated reduces the chances of forming competing fractures in the formation during fracturing.

  • Publication number: 20170328134
    Abstract: A method and system for downhole operations that includes an energetic material with a reduced sensitivity to temperature, and a temperature rating that is higher than other energetic materials. Downhole tools that use energetic material thus can have a higher temperature rating with the reduced sensitivity energetic material. One embodiment of the energetic material includes an energetic heterocycle compound, such as 2,6-diamino-3,5-dinitropyrazine-1-oxide.

  • Patent number: 9080433
    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.

  • Publication number: 20140000908
    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.

  • Publication number: 20130048302
    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.

  • Patent number: 8347962
    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.
