Abstract: A joint spacer therapeutically maintains separation of bones of a joint. A carriage is slideably retained within the frame and has at least one ramped surface. An actuator screw is threadably engaged with the frame, and rotatably connected to the carriage, to cause the carriage to slideably move within the frame when the actuator screw is rotated. First and second endplates engage the bones of the joint, and each has at least one ramped surface that is mateable with the ramped surface of the carriage, whereby when the carriage is slideably moved by rotation of the actuator screw, the endplates ramped surface slides against the carriage ramped surface to cause the endplates to move along an axis transverse to the longitudinal axis of the frame, to increase the height of the spacer. Piercing elements are connected to the carriage to pierce bone of the joint when the carriage is moved.

Abstract: An in-field powered distributed pumping system and method are provided. The system includes a pump unit disposed at a first location and a slurry pump unit disposed at a second location. The system also includes at least one grid power supply, wherein at least one of the pump unit and the slurry pump unit is powered by the at least one grid power supply. The system further includes a first flow path fluidly connected to the pump unit at the first location and configured to fluidly connect the pump unit to a well bore, and a second flow path fluidly connected to the slurry pump at the second location and configured to fluidly connect the slurry pump unit to the well bore.

Abstract: Disclosed are systems and methods for detecting the beginning of a flush volume. A blended fluid is output by a fluid blending apparatus and pumped into a wellbore. The blended fluid transitions from a first composition to a second composition. A blending signal comprising time-varying data relating to characteristics of the blending apparatus or measured from sensors associated with the blending apparatus is received. Based on a first portion of the blending signal corresponding to the first composition, a calibration profile is generated. Based on the calibration profile and a second portion of the blending signal corresponding to the second composition, a transition indicator corresponding to a change in the blended fluid from the first composition to the second composition is determined. Based on the transition indicator, a flush signal indicating the beginning of a flush volume being output by the blending apparatus and pumped into the wellbore is generated.

Abstract: A method of conducting fracturing operations at multiple wellsites in a field. The method may include manufacturing a first fracturing fluid concentrate at a fluid manufacturing plant located at a sand mine of the field using sand produced from the sand mine. The method may also include pumping the first fracturing fluid concentrate from the fluid manufacturing plant to a first well and a second well of the multiple wellsites.

Abstract: A load sense pump can be used as a backup for a pressure-compensated pump in a wellbore operation. A pumping system can include a first pump, a second pump, a check valve, and a directional control valve. The first pump, which can be a load sense pump, can be used to provide pressure to a first hydraulic load. The second pump, which can be a pressure-compensated pump, can be used to provide pressure to a second hydraulic load. The directional control valve can be controllable to cause the first pump to change operation to provide pressure to the first hydraulic load and through the check valve to the second hydraulic load.

Abstract: A method of delivering a treatment fluid into a subterranean formation and system therefor are provided herein.

Abstract: Controlling the dust emissions from the discharge of bulk materials from a container provides many benefits. A support structure may include a plurality of outlets or chutes for discharging the bulk material. A dust control damper coupled to the outlets not currently in use for the discharge of bulk material may prevent dust from escaping into the surrounding air. The dust control dampers may automatically transition between a closed position and an open position. A flexibly collapsible shroud may also be coupled to a discharge gate of a container. The shroud may expand to seal against the outlet when bulk material is discharge. A vacuum system at or near an outlet may reclaim any dust that escapes during discharge of the bulk material.
