Abstract:
A release assembly (200) for releasing a portion of a tool string in a wellbore. The release assembly (200) includes an outer housing (202) having a fishing receptacle (206) disposed therein. The fishing receptacle (206) includes a fishing neck (208). A support assembly (214) is disposed within the housing (202). The support assembly (214) has a first position wherein the support assembly (214) engages the fishing neck (208) to prevent separation of the fishing receptacle (206) from the housing (202) and a second position wherein the support assembly (214) is disengaged from the fishing neck (208) no longer preventing separation of the fishing receptacle (206) from the housing (202). An actuator (224), disposed within the housing (202), maintains the support assembly (214) in the first position until actuation thereof allows the support assembly (214) to shift to the second position.
