An apparatus for connecting a main casing section to a lateral casing section using thermoset plastic molding. The apparatus is used to set a flexible sock made of a hardenable material at a location adjacent to an intersection between the main and lateral casing sections. The sock is inflated so that it conforms to the inner surfaces of the main and lateral casing sections. Heat is applied to the hardenable material so that the sock is cured in the inflated, operating position. Heat may be applied by releasing chemicals which provide an exothermic reaction and/or by using a heater positioned within the sock.

Apparatus and method for connecting casing to lateral casing using thermoset plastic molding

A method and apparatus using hydrajetting of fluid to cut a lateral casing window for drilling a side track. The apparatus comprises a J-sub having a J-slot therein which guides movement of a jetting nozzle such that a window may be abrasively jetted in well casing in the general shape of the J-slot. In an alternate embodiment, a hydraulically activated actuator sub is used to operate the J-sub. The actuator sub is activated by alternately pressurizing and depressurizing the actuator sub to apply longitudinal movement and torque to the J-sub.
