Abstract: Wellbore systems containing a hydraulically regulated primary safety valve may have their hydraulic regulation transferred to an insert safety valve disposed in a nipple. Transfer of the hydraulic regulation may take place mechanically, such as through axial displacement of a sliding sleeve or by replacement of a hydraulic spool. Wellbore systems configured for axial displacement of a switching mechanism may comprise: a tubing string comprising a nipple and a primary safety valve, the primary safety valve being disposed in the tubing string above or below the nipple; a control line and a balance line in hydraulic communication with the primary safety valve and in latent hydraulic communication with an internal flow pathway within the nipple; and a switching mechanism that is axially displaceable to establish hydraulic communication between an insert safety valve positioned in a bore of the nipple and both the control line and the balance line.

Abstract: In accordance with presently disclosed embodiments, systems and methods for managing dry bulk material efficiently at a well site or other location are provided. Present embodiments are directed to a rotary clamshell gate actuation system and method, where the gate is separate from the one or more actuators used to open/close the gate. The disclosed system may include a portable bulk material container with a clamshell gate for easily dispensing material from the container. The system also includes a support structure equipped with one or more rotary actuators used to actuate the clamshell gate of the container between a closed and open position when the container is positioned on the support structure. The disclosed clamshell gate actuation system is easy to operate, low cost to manufacture, and reliable even when the portable container is not precisely aligned on the support structure.

Abstract: Certain aspects of the present disclosure are directed to tools actuated by pipe swell. A downhole assembly for a wellbore may be provided. The downhole assembly can include a first sleeve and a second sleeve. The first sleeve can expand from a first position to a second position in response to a first pressure applied to the first sleeve. The first sleeve can contract to the first position in response to a cessation of the first pressure. The second sleeve can be positioned adjacent to the first sleeve to define a swell chamber. The swell chamber can actuate a downhole tool by a pressure stored in the swell chamber by the expansion of the first sleeve.

Abstract: A device for reducing the catch of unwanted species of organisms in fishing trawls which allows the retention of shrimp and the escape of fish from the trawl. The device features a longer, smaller diameter cylinder nested within a shorter, larger diameter cylinder in such a way as to create a continuous escape opening around the entire circumference of the net. The trawl bag is attached to the downstream end of the outer cylinder and the trawl body is attached to the upstream end of the inner cylinder. Flow blocking plates, set at an approximate 45° angle ahead of the escape opening, create an area of reduced water flow in and around the escape opening. Fish naturally move into the slower water flow and into the escape opening. Fish then move out of the trawl. Shrimp, being weaker in their swimming abilities are unable to move into the slower water areas and are therefore carried into the trawl bag and are captured.

Abstract: A support system that is portable. The support is made up of two pieces of tubular steel where one is smaller and can fit inside the other. While in this condition the steel pieces are held together by a nut and bolt that are placed through a hole on one end of the tubes. There is a square hole machined on the other end of the large tube and perpendicular to the first hole. This hole allows the smaller to tube to fit in perpendicular to the large tube. To complete the assembly the two tubes are held in place by the same nut and bolt. There is a piece of angle iron welded on the large tube, at the same end and parallel to the square hole. One unit will have two support assemblies held together with a chain and clevis system. The final product will use two units placed at either end of a set of horizontal utility poles to keep them in place during storms or high winds.
