The locating sub system and method for orienting and/or positioning a tool within a well-bore allow for orientation and positioning of one or more tools within a well-bore to perform precise operations within a well-bore. The locating sub apparatus can include a latching member that engages and causes a tubular member to rotate to a desired orientation and/or position for down-hole operations. The locating sub apparatus can further include a sacrificial sub that houses a latching member and a tubular member to traverse the well-bore to the site for down-hole operations. Upon completion of down-hole operations as desired or in an emergency, an upward force can be exerted upon the tubular member thereby disengaging an frangible member causing the tubular member to disengage from the latching member allowing for retrieval of the tubular member through the well-bore.
