Abstract: Explosive cutter assemblies and methods include a liner having a single unitary body, and an explosive charge disposed within the liner. The explosive charge includes a continuous unitary body of explosive material having a first area disposed in association with an inner surface of the liner and a second area extending from the center of the assembly to the first area. A detonator can be used to ignite the second area of explosive material, causing propagation of a detonation to the first area, which in turn causes deformation of the liner and projection of the liner toward a target to form a cut. An adaptor sub having a detonator within can be inserted into the cutter assembly to secure the assembly together, position the detonator in association with the explosive material, and engage a conduit usable to raise and lower the cutter assembly and transmit a detonation signal.

Abstract: A system and method are usable as a telescoping, small-scale oil rig, having the ability to rotate tubulars in a wellbore, pull tubulars from the wellbore, and insert tubulars into the wellbore. The system comprises a telescopic derrick section, a casing jack platform, and a base section. The telescopic derrick comprises U-shaped substructure frames that can be nested together, and is connected to an adjacent substructure through hydraulic cylinders. When pressurized, the cylinders extend to separate each substructure and raise the telescopic derrick. The casing jack platform comprises a traveling casing jack and spider for holding, inserting and removing tubulars. The base section supports the telescopic derrick and comprises a rotary floor and another spider for holding, inserting and removing tubulars into and from the wellbore. The combination of the traveling spider and stationary spider can be used for inserting tubulars into the wellbore when the well is under pressure.

Abstract: An apparatus for ultrasonically inspecting a component comprises a first ultrasonic transducer for transmitting an ultrasonic signal into a component having rotational symmetry and a second ultrasonic transducer for detecting the reflected, or transmitted, ultrasonic signal. A motor and a turntable produce relative rotation between the rotationally symmetrical component and the first and second transducers. Motors, a carriage and tracks on a frame provide relative radial motion between the rotationally symmetrical component and the first and second transducers to scan the whole of a surface of the rotationally symmetrical component. An ultrasonic signal analyzer analyses the detected ultrasonic signal by monitoring for ultrasonic signals having an amplitude above a predetermined amplitude and not having rotational symmetry and a display provides an indication that any detected ultrasonic signals above the predetermined amplitude and not having rotational symmetry is a potential flaw in the component.
