Abstract: A wireline conveyed, gas driven setting tool configured to set downhole tools including, without limitation, frac plugs, bridge plugs, cement retainers and packers. The setting tool is functioned by selectively igniting a power charge inside of a firing head. As the power charge burns, it generates gas that acts upon a piston area to stroke the setting tool. A dampening media, as well an optimized flow area at or near the distal end of the setting tool, act to slow the setting stroke.

The tool section can be in the form of a signal valve section of a mud pulse telemetry valve, a reamer, a vertical steerable tool, a rotary steerable tool, a by-pass valve, a packer, a whipstock, or stabilizer.

Abstract: This disclosure presents an apparatus to improve the indication of an amount that a fluid valve is opened. The fluid control assembly includes an improved position sensor assembly (PSA), where the PSA uses rollers rather than sliding within the PSA housing. The rollers, which can be wheels, ball bearings, and other types of rolling devices, can reduce the friction experienced by the moving component within the PSA. Since the PSA mechanism can move with less friction, the coupled valve magnetic assembly (VMA) can also be enhanced. The VMA can utilize magnets in orientations that enhance the magnetic tensile and compressive forces. For example, some magnets in the VMA can be in a perpendicular orientation to improve directional control and some magnets can be in an angled orientation to reduce the spread of the magnetic field flux lines between the magnets of the VMA and the magnets of the PSA.

The composite shock absorber can weaken damage of the slippage effect to polycrystalline diamond compact cutting teeth, absorb axial vibration from a drill stem and prolong the service life of the bit.
