The male conversion means and/or external/internal fishing neck is disposed at the lower end of the hydraulic release tool, and is released when the work string tools become stuck, thus allowing the stuck work string tools to become relieved by any conventional standardized overshot fishing tool; while also allowing the retrieval of the tubing above the released hydraulic release tool.

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.

Abstract: A mechanical down jar and method for its use in releasing stuck objects within a well bore and for conducting other downhole servicing operations. The mechanical down jar mechanism incorporates a tubular body having fixed anvils and telescoping mandrels at each end, the lower of which is connected to the stuck object. An internal load spring is released upon application of predetermined downward force to the housing by a firing lug and firing ring release mechanism having an adjustable release force. When released the lower anvil of the housing is rapidly moved downwardly by the force of the load spring and impacts with significant force against the force transmitting sub of the lower mandrel thus transmitting downwardly directed shock force to the stuck object.

Abstract: A ratcheting fishing tool having a generally cylindrical body connected with and housing a rotary ratcheting device along with an operating shaft axially mounted to reciprocate within the body and also connected to the ratcheting device. A fish grappling apparatus, having a first element connected to the housing and a second element connected to the shaft, operates to grasp a fish with the operating shaft being in a first axial position with respect to the housing and to be free of the fish with the operating shaft being in a second axial position. The ratcheting mechanism is adapted to be axially moved successively against a spring return with each movement actuating the rotary ratchet to latch the operating shaft alternately in a first axial position and in a second axial position. Ratcheting fishing tool is disclosed in an overshot fishing tool embodiment and a spear fishing tool embodiment.

Abstract: A mechanical down jar and method for its use in connection with coil tubing and with jointed tubing for releasing stuck objects within a well bore for installing coil tubing within deviated and horizontal well bores and for conducting other downhole servicing operations. The mechanical down jar mechanism incorporates a tubular body of significant mass having fixed anvils and telescoping mandrels at each end. The lower mandrel is adapted for connection to the stuck object. An internal load spring is released upon application of predetermined downward force to the housing by a firing lug and firing ring release mechanism having an adjustable release force. When released the housing with its lower anvil is rapidly moved downwardly by the force of the load spring and an accelerator spring impacts with signficant force against the force transmitting sub of the lower mandrel thus transmitting downwardly directed shock force to the stuck object or to tubing to be moved downwardly.

Abstract: A jar tool for inclusion into a well fishing operating string which provides resilient tensional stretch to operate the tool. The tool is adapted to compress an upper release spring to store energy corresponding to tensional force in the operating string force. A release latching lug array connects the spring to a central mandrel having an impact hammer. The tool housing forms an impact anvil. The spring is compressed to a designated compressional force by the distance that the latch lug array is moved in an adjustable latch release sleeve before suddenly releasing the spring from the mandrel. The tension in the operating string then pulls the mandrel hammer into jarring impact with the housing anvil. Provision is made for designating this pre-release movement of the latching lug array and also provides apparatus for adjusting the distance of the pre-release movement and thereby the compressional force imparted into the spring.

Abstract: A downhole fishing jar mechanism for freeing stuck objects within a well bore which incorporates a housing structure defining an internal anvil element through which an upwardly-directly impact force is adapted to be transmitted to the body structure. A striker element, incorporated with an elongated operator element is adapted to strike the anvil with an impact force that is controlled by means of an adjustable compression spring. A spherical detente-type latching mechanism is adapted to establish a releasable interconnection with the operator element and further is operative to transmit the compression of the spring to the operator element. The latch mechanism releases automatically upon predetermined upward movement of the operator element and latch mechanism within the body structure, thereby allowing the operator element to move upwardly and cause the striker to impart a predetermined impact force to the anvil.
