Abstract: A site may require that multiple containers, such as bulk material containers, may be utilized to provide a required composition or mixture of materials at a required discharge rate. An arrangement of four or more containers on a frame disposed on a support platform where two faces of each container proximate or adjacent to a face of two other containers to form a rectangle provides a configuration that allows for safe and efficient removal and replacement of containers A rotary table coupled to a motor disposed on the support platform rotates the frame such that each container transitions to different positions. The containers discharge material through an opening of support platform. Containers may be retrieved from one position and replaced at another position or retrieved and replaced from a single position. Such a configuration allows for multiple transport devices to operate without interfering with the operations of each other.

Abstract: A valve poppet assembly comprising a valve stem, a poppet insert retainer, and a poppet seat, wherein, in an assembled configuration, the valve stem extends along a central axis through the poppet insert retainer and the poppet seat, and wherein the valve stem, the poppet insert retainer, and the poppet seat are not a single, integral component.

Abstract: Certain conditions require powering down an engine driving a pump. During the down sequence the pump may continue pumping servicing fluid which may not be desirable. Activating one or more control valves may throttle or prevent the servicing fluid from being pumped from the pump during the power down sequence. Activation of an input control valve may introduce pressurized fluid into a cylinder of the pump extending a rod to force or maintain a suction valve in an open position. While the suction valve is in the open position, the stroke of the plunger may not create enough pressure to pump the servicing fluid causing the servicing fluid to flow between a fluid header and a chamber of the pump. Activation of an output control valve may divert servicing fluid pumped from the pump to a reservoir instead of to the desired location.

Abstract: A flow exchanger (FE) system comprising: a supplement pump receiving a supplement first fluid stream and outputting a pressurized supplement first fluid stream; a flow splitter comprising a flow restrictor, wherein the flow splitter receives the pressurized supplement first fluid stream and outputs a power stream and a treatment stream; a main flow manifold, wherein the treatment stream enters the main flow manifold subsequent to passing through the flow restrictor; and an FE cylinder filled downstream with a second fluid and having a fluid interface separator (FIS), wherein the power stream enters the FE cylinder upstream; wherein the power stream engages and pushes FIS downstream, thereby providing for a second fluid stream entering the main flow manifold; wherein a second fluid stream VFR=a power stream VFR; and wherein the main flow manifold provides for a manifold output fluid stream VFR=a pressurized supplement first fluid stream VFR.

Abstract: Certain conditions or triggering events require preventing or throttling the discharge of a servicing fluid from a pump to a wellhead or a borehole. Powering down may not be desirable or may require a duration that allows the condition or triggering event to persist. Selectively and automatically activating one or more pressure control valves may throttle or prevent the servicing fluid from being pumped from the pump during the power down sequence or without requiring a power down sequence. Selective activation of a pressure control valve may introduce pressurized fluid into a cylinder of the pump extending a rod to force or maintain a suction valve in an open position. While the suction valve is in the open position, the stroke of the plunger may not create enough pressure to pump the servicing fluid causing the servicing fluid to flow between a fluid header and a chamber of the pump.

Abstract: A containment apparatus is provided having a container body enclosing an inner cavity for containing fluids. The container body has a mouth and a metering aperture each passing through the container body permitting fluidic communication from the inner cavity to outside the container body. A flexible inert barrier is provided within the inner cavity and fluidically separating the mouth and the metering aperture, the flexible inert barrier forming a protective liner along the surface of the inner cavity when filled with a harsh fluid introduced from the mouth, and collapsible toward the mouth upon a greater differential pressure experienced from a benign fluid introduced from the metering aperture whereby the harsh fluid is forced out of the mouth, a portion of the surface of the inner cavity being exposed to the benign fluid upon collapse of the flexible inert barrier.

Abstract: Systems and methods for managing bulk material efficiently at a well site are provided. The disclosure is directed to a container support frame that is integrated into a blender unit. The support frame is used to receive one or more portable containers of bulk material, and the blender unit may include a gravity feed outlet for outputting bulk material from the containers directly into a mixer of the blender unit. The blender unit with integrated support frame may eliminate the need for any subsequent mechanical conveyance of the bulk material (e.g., via a separate mechanical conveying system or on-blender sand screws) from the containers to the mixer. As such, the integrated blender unit may be lighter weight, take up less space, and have a lower cost and complexity than existing blenders.

Abstract: In accordance with presently disclosed embodiments, systems and methods for using containers, instead of pneumatic transfer, to move bulk material from a transportation unit to a blender receptacle (e.g., hopper or mixer of a blender) are provided. A transportation unit may deliver multiple containers of bulk material to the well site, where multiple conveyors may deliver the containers to a location proximate the blender receptacle. Openings at the bottom of the containers are arranged adjacent one another so that the load of two containers may be delivered to the tight space occupied by the blender receptacle. Since the transportation unit is able to unload the containers of bulk material without pneumatic transfer, the containers may enable a cleaner and more efficient bulk material transfer at the site.

Abstract: Electrically ignitable and electrically controllable explosive material (EIECEM) may be disposed within a shaped charge for deployment downhole. An explosion of the EIECEM is controlled by limiting the duration of excitation at the EIECEM, for example, the duration that an electrical source provides an electrical charge, electrical current or electrical signal. The shaped charge may be insulated from an electrical source to prevent explosion of the EIECEM and coupled to the electrical source to create ignite or explode the EIECEM. A plurality of shaped charges may be disposed downhole and may be ignited or exploded in any suitable order. The EIECEM may be ignited multiple times such that multiple explosions are created. The explosion of the EIECEM creates or extends a perforation or fracture in a formation. The shaped charges may be excited in a predetermined sequence and for a predetermined duration of time.

Abstract: Methods for creating vertical mini-holes in a subterranean formation while creating multi-directional Bernoulli-induced fractures therein are provided. These methods are particularly useful in horizontal or deviated wells. In some embodiments, the method includes forming a mini-hole in the subterranean formation perpendicular to the deviated wellbore.

The method further includes injecting fluid into the mini-hole with a maximum pressure forming at the tip so as to initiate a fracture along local formation stresses proximate the tip of the mini-hole.
