摘要： The invention relates to techniques for severing a tubular. A blowout preventer is provided with a housing (12) having a bore (32) therethrough for receiving the tubular, an actuator (152) positionable in the housing, and a plurality of cutting tools (248) positionable in the housing and selectively movable into an actuated position with the actuator. Each of the cutting tools (248) have a base (404) supportable by the actuator and selectively movable thereby, and a cutting head (400) supported by the base. The cutting head comprising a tip having a piecing point (200) at an end thereof and at least one cutting surface (406). The piercing point pierces the tubular and the cutting surfaces taper away from the piercing point for cutting through the tubular whereby the cutting head passes through tubular.

摘要： A system for producing mechanical energy. In some embodiments, the system includes a first source providing a first fluid, a fluid pressurization device, a second source supplying a second fluid, a first motor, and a second motor. The fluid pressurization device draws in the first fluid from the first source and increases the pressure of the first fluid. The first motor is driven by the second fluid, the second fluid decreasing in pressure and the first motor powering the fluid pressurization device as the second fluid passes through the first motor. The second motor receives a mixture of the first fluid from the first motor and the second fluid from the fluid pressurization device, whereby the second motor produces the mechanical energy.
