Abstract: An apparatus for enhancing production from a wellbore hole may include a body member having at least one cutting assembly. Each cutting assembly may have an upper, middle, and lower cutting arm. The cutting arms are hingedly connected to one another. An upper end of each upper cutting arm is hingedly connected to the body member. A lower end of each lower cutting arm is hingedly connected to a corresponding beveled attachment that is slidably received within a corresponding beveled groove in the body member. The body member includes an interior longitudinal bore in fluid communication with a jet nozzle that is located beneath each cutting assembly. The apparatus is connected to a drill string. As the drill string is rotated, each cutting assembly is moved to a fully-deployed position under centrifugal force, thereby enlarging the wellbore hole. Drilling fluid may be pumped into the apparatus to generate hydraulic power to carry loose cuttings to the surface.

The second end of a connector member is connected to the first end of the other anchor plate.

Abstract: A compact oven assembly has a housing and a high power density, low mass heating element. The housing defines a cooking cavity and a slot which permits access to the cooking cavity. The high power density, low mass heating element is supported by the housing above the cooking cavity. The compact oven assembly may include a food support which is arranged so that, when the food support is inserted into the cooking cavity through the slot, the slot of the housing is substantially closed off. The compact oven may also include a switch operated by the food support when the food support is inserted into the cooking cavity through the slot in order to energize the high power density, low mass heating element. Each high power density heating element has a formed parabolic reflector located above it and opposite to the cooking plane. Accordingly, the energy from the high power density heating elements is directed toward the cooking plane.

Abstract: An improved method and apparatus for sealing a junction between a central and lateral wellbore is provided. In a broad aspect, the method of the present invention includes installing a polymerizable sealing sleeve within a first casing in a central wellbore at a junction between the first casing and a second casing in a lateral wellbore. After the sealing sleeve has been installed and allowed to cure, a milling tool is used to mill a window through a sidewall of the sealing sleeve and flush with the inner diameter of the second casing. The sealing sleeve may be used alone to establish a primary seal, or in combination with cement or other sealing substance, as used heretofore in prior art sealing methods, as a back-up seal. The sealing sleeve of the present invention may be provided with at least one orienting means to enable the second casing to be located and to direct a well tool thereinto.

Abstract: An improved downhole explosive charge carrier is disclosed. The invention uses a unique staggered charge pattern and a mounting configuration which allows the use of a straight, axially-located detonator in order to achieve a greater number of shots per unit length over conventional carriers. The invention also reduces the interference caused by the detonator and the closeness of the shots and thereby increases the performance of the individual charges, allowing smaller charges to be used to achieve the same perforation size.
