    摘要： A ramp type frac plug device of the present invention is a simplified, short and compact frac plug device to both maintain seal to the borehole wall and prevent premature release from the borehole. The frac plug device includes a cone, an anchor assembly, a cap member, a slip device, and a sealing member. In a set configuration, the frac plug device has both the friction fit engagement of the cone and the slip device and a single direction rachet locked engagement of an anchor ring with a threaded ring portion and an anchor mandrel with an exterior threaded mandrel portion of the anchor assembly. The ratchet lock engagement between the anchor ring and the anchor mandrel prevents backward movement of the cone away from the anchor mandrel so that the cap member engaged with the anchor mandrel locks the slip device in position on the cone.

    摘要： A frac plug has a bottom shoe, a single slip ring supported by the bottom shoe, a slip wedge positioned above the slip ring and axially movable relative to the slip wedge, a radially outwardly expandable sealing element supported by the slip wedge and a deformable backup shoe fixed to the sealing element. The deformable backup shoe has a cap covering at least a portion of a top surface of the sealing element and an outer leg extending along at least a portion of an outer surface of the sealing element. A ball seat is insertable into the radially outwardly expandable sealing element.

    摘要： 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.

    摘要： A wash tool comprises a mandrel with a central annulus and one or more lateral bores and one or more ring-shaped rotary hubs positioned about the mandrel adjacent to the one or more lateral bores. The rotary hubs comprise lateral bores perpendicular to the lateral bores of the mandrel such that pressurized fluid introduced to the central annulus of the mandrel impacts the inner surface of the rotary hubs and forces them to rotate, delivering pressurized fluid to the inner surface of a wellbore or tubular. The wash tool is modular and can be attached to a top sub or bottom sub, and may be used with or without a wireline. When used with a wireline, the wireline is insulated from the wash fluid by means of a tie-back and multiple seals.

    摘要： An annular pressure activated downhole tool has a housing including an outer surface, an inner surface defining a passage, an annular projection projecting into the passage from the inner surface, and an opening. A mandrel extends into the passage. The mandrel has a first end and a second end. A power spring support is detachably connected to the second end of the mandrel in the passage. A power spring is arranged about the mandrel and extends between the power spring support and the annular projection. A trigger housing is arranged in one of the mandrel and the power spring support. A trigger arranged in the trigger housing selectively engages with the inner surface. The trigger is operable to disengage from the inner surface of the housing, releasing the power spring, and shifting the mandrel along the passage when exposed to a selected annular pressure.
