  • Self-orienting selective lockable assembly to regulate subsurface depth and positioning
    Patent number: 11634955
    Abstract: A well tool to be oriented and secured in a wellbore without the external application of torque, and a well system incorporating the same. After installation of orientation casing and universal latch coupling casing, the self-orienting selective lockable latch well tool is run downhole to the target depth, picked up to free the internal locking mechanism, and then loaded with downhole stress to engage the locking mechanism.
    Type: Grant
