A perforating apparatus according to one or more aspects of the present disclosure comprises a carrier adapted to be deployed in a wellbore; a shaped explosive charge mounted on the carrier, the shaped charge comprising an explosive disposed inside of a case; and a conically shaped liner having an apex and a base disposed with the explosive in the case, the liner comprising an electromagnetically formed portion. The electromagnetically formed portion may comprise a thickness at the apex that is different from a thickness at the base.

Electromagnetic formed shaped charge liners

A powered dispenser is provided for cosmetic sticks. The dispenser includes a case and a cosmetic cup that is disposed within the case and that is dimensioned for holding a cosmetic stick. A powered control mechanism is provided for moving the cup upwardly and downwardly within the case so that a cosmetic stick, such as lipstick, is selectively movable between an extended position wherein it can be applied by the user and a retracted, storage position within the case.

Rod Float Mitigation (RFM) methods for rod-pumped oil wells having a variable frequency drive which controls the speed of the motor for the pump. Each method monitors rod loads or a similar condition and takes action only when rod load drops below a predefined minimum load. A first method reduces the speed of the motor to a preset level. A second method fixes the torque level on the pump downstroke by adjusting motor speed based on a calculated gearbox torque compared to a programmed fixed limit. Another method includes a program in the variable frequency drive which includes a preferred RFM Torque Curve for the pump to follow on its downstroke. When rod float occurs, the program monitors gearbox torque and adjusts the speed to follow the predetermined RFM Torque Curve thereby mitigating rod float with minimum decrease in production.

Apparatus, methods and products for monitoring/controlling a reciprocating well producing hydrocarbons from a wellbore, which determine the surface card from a well operating characteristics, determine the downhole card, and display both at the same scale for position.

An improved beam pumping unit for pumping fluids from a well having a foldable support structure to allow storage of the pumping unit in a low profile position. The beam pumping unit utilizes a walking beam pivoted on a central bearing, a drive means connected to one end of the walking beam to oscillate the walking beam and a horsehead at the other end of the walking beam for connection to the polished rod of the downhole pump. A foldable Samson post supports the central bearing of the walking beam. The foldable Samson post allows lowering of the pumping unit from a first, fixed standing position in which the walking beam is raised for normal pumping operation and a second, fixed lowered position for storage.
