Abstract: A portable linear fastener driving tool is provided that drive staples, nails, or other linearly driven fasteners. The tool uses a gas spring principle, in which a cylinder filled with compressed gas is used to quickly force a piston through a driving stroke movement, while a driver also drives a fastener into a workpiece. The piston/driver is then moved back to its starting position by use of a rotary-to-linear lifter, and the piston again compresses the gas above the piston, thereby preparing the tool for another driving stroke. The driver has protrusions along its edges that contact the lifter, which lifts the driver during a return stroke. A pivotable latch is controlled to move into either an interfering position or a non-interfering position with respect to the driver protrusions, and acts as a safety device, by preventing the driver from making a full driving stroke at an improper time.

Abstract: Embodiments of this disclosure provide a method and apparatus to inject an abrasive fluid mixture into a high-pressure fluid flow using a clear fluid pump. The high-pressure fluid flow may be used in abrasive jet perforating and hydraulic fracturing applications in oil and gas wells, and other oilfield related work that uses high pressure fluids containing abrasive material. The embodiments include inserting abrasive material downstream of a high-pressure pump, such that a pump without specialized capability for abrasives (e.g., a clear fluid pump) can be used instead of a specialized pump that can withstand abrasives (e.g., hydraulic fracturing pump, oilfield cementing pump).

Abstract: A frac plug with lower slips and a lower cone. In embodiments, a lower cone ramp angle is greater than or equal to a cone bevel angle and a slip inner cut angle. This geometry enables the fins of the cone to not interact with the lower slips, which may not break the lower slips as the lower slips move over the cone. Instead, the lower slips may break due to stresses caused by the tendency of the lower slips to expand as they lower slips interact with the ramp of the lower cone.
