ABSTRACT:
This invention relates to the method and apparatus for locating and indicating collars and tubing ends through the use of a locator capable of repetitive use in a number of runs downhole in any given tubing situation. Specifically, this invention relates to a series of compressive springs and bows protruding radially outward from the locator and coming into contact with the inner bore of the tubing, thereby indicating upon contact with the collar or tubing end when run downhole. Therefore, this invention relates to a new and improved tubing end locator capable of running a number of times downhole to locate collars and tubing ends without the necessity of removal of the tubing end locator uphole and re-working or re-tooling. Alternatively, this locator may be used as a centralizer to center any object within the tubing that is connected to the locator.
