  • Multi-phase charge holder
    Patent number: 4694754
    Abstract: A shaped charge carrier assembly apparatus includes a carrier having a plurality of carrier segments integrally formed from a single substantially flat elongated sheet of structural material. An interconnecting portion is located between each two adjacent segments and is integrally connected therewith. The interconnecting portion provides a rigid and precise angular offset between adjacent segments through a permanent deformation of the interconnecting portion. Each carrier segment has a charge receiving opening therein and includes a pair of diametrically opposed wedges for snugly enaging a pair of elastomeric lugs of a shaped charge.

  • Back-off tool
    Patent number: 4537255
    Abstract: A back-off tool comprising an explosive contained in a tubular housing which will disintegrate into fine particles upon detonation of the explosive. The explosive may be in the form of pellets so as to have the capability to vary the amount of explosive force by employing different diameter pellets and different numbers of pellets in the housing. A pressure compensation arrangement may be employed.

  • Method and apparatus for forming internal recesses in a hollow body
    Patent number: 4116110
    Abstract: Apparatus for forming a recess in an internal surface of an elongated hollow body comprised of a housing having a rotary mill and means for rigidly clamping the housing at a desired position within the interior of the body attached thereto. Means operable from the exterior of the body are provided for clamping the housing within the interior of the body and selectively moving the mill into contact wth an interior surface of the body whereby a recess is formed therein.

  • Shaped charge well perforating apparatus
    Patent number: 4071096
    Abstract: Apparatus for perforating a well comprised of a closed retrievable carrier formed in an elliptic cylindrical shape and having shaped charge perforating means disposed therein. Upon actuation of the shaped charge perforating means the ellipticity of the carrier is reduced.
