Abstract: A shaped charge having a liner with three frustoconical segments and a bottom portion configured to provide consistent perforating holes over a range of distances from the shaped charge.

Abstract: A method and apparatus for perforating a wellbore by firing one or more projectiles into a casing and formation using a single source of energy.

Abstract: Methods for providing wellbores for electromagnetic heating of a hydrocarbon formation positioned below a ground surface and apparatus thereof are provided. The apparatus includes two or more wellbore casings positioned within two or more wellbores. The two or more wellbores extend from a proximal end at the ground surface to a distal end at the underground hydrocarbon formation. Each of the two or more wellbore casings have a proximal portion and a distal portion. The two or more wellbores are in proximity to one another at a junction. The apparatus also includes a first electrical connection between the proximal portions of the two or more wellbore casings for grounding the two or more wellbore casings and a second electrical connection between the distal portions of the two or more wellbore casings. The second electrical connection is located at the junction and provides a short circuit that reduces current traveling on the two or more wellbore casings to the ground surface.

Abstract: The device disclosed herein is suitable for simultaneously cleaning opposing surfaces of the Juliette-style balcony windows. The device is constructed to have dimension that, when in a compact form, it can be inserted into the gap formed between a balcony or patio door and a balcony facade and hand rail. A pair of cleaning heads, situated on opposite sides of an expandable or inflatable member, can be positioned to contact the opposing glass surfaces by actuation of the expandable or inflatable member from the compact to the expanded position. Subsequent manual movement of the opposing pair of cleaning heads, in combination with the application of water and optional cleaning products, resulting in the cleaning of the opposing surfaces of the Juliette balcony window.

Abstract: A tubing string, such as a coiled tubing or jointed tubing string, has an agitator mounted within an interior of the tubing string at an intermediate position between an uphole end and a downhole end of the tubing string. A tubing agitator is structured to be installed within a tubing string. A method includes: forming or installing a seat within an interior of a tubing string at an intermediate position between an uphole end and a downhole end of the tubing string; and conveying an agitator through the interior of the tubing string until the agitator contacts the seat. A hammer drift tool is also described.

Abstract: A method and apparatus for containing one or more shaped charges in a single plane, using a shaped charge housing containing a cluster of one or more shaped charges, with the apex ends facing each other, arrayed about the center axis of a gun body, and detonated from a single initiator located in the middle of the cluster of the one or more shaped charges, the shaped charge housing can be one of many shaped charge housings coupled together to perforate in a plurality of single planes.

Abstract: A firearm accessory is operable in two modes. A first mode in which the firearm accessory is coupled, at least indirectly, to a firearm to define a foregrip. In the first mode, a blade on the accessory is in a sheathed position. A second mode in which the firearm is disconnected from the firearm to define a knife. In the second mode, the blade is in an extended position. In each mode and position, the tip of the blade is vertically above the upper end of the grip body. The firearm accessory has prongs that connect the grip body to an attachment mechanism or coupler. Within the coupler are flexible liner locks that have sloped protrusions that engage recess in the blade to lock the blade in the extend position. The liner locks may be flexibly unlocked by depressing a button carried by the grip body.

Abstract: An apparatus and method for connecting a shaped charge retainer to a shaped charge and connecting that to a charged tube in a perforating gun for use downhole.

Abstract: An apparatus may have a drill string located in a well that penetrates a formation within the earth; and a downhole tool located as part of the drill string, the downhole tool comprising a landable and/or retrievable agitator. A downhole tool has a housing and a landable or retrievable agitator. An apparatus has plural retrievable and/or landable agitators positioned in series in a tubing string downhole.

Abstract: Examples are disclosed for configuring a solid state drive (SSD) to operate in a storage mode or a memory mode. In some examples, one or more configuration commands may be received at a controller for an SSD having one or more non-volatile memory arrays. The SSD may be configured to operate in at least one of a storage mode, a memory mode or a combination of the storage mode or the memory mode based on the one or more configuration commands. Other examples are described and claimed.
