Abstract: A wireline delivery tool for an underground well having a pipe, a surface seal for the pipe, and a wireline extending from the surface into the pipe. The wireline delivery tool includes a body having a diameter less than the interior diameter of the pipe and a cup extending from the body to create a seal with the interior of the pipe. A longitudinal bore within at least a portion of the body has a port through the body on each side of the cup, so that the ports are in communication with the interior of the pipe. A pressure valve within the bore is normally in the closed position. Pressure supplied into the pipe between the surface seal and the cup will move the delivery tool within the pipe.

Abstract: A device for positioning a tool or instrument in a duct and recovering the tool or instrument therefrom by causing a vector fluid to flow through the device. The device includes a tubular element adapted to be connected to the tool or instrument and an annular sealing arrangement mounted on the tubular element for sealing the tubular element in the duct. The tubular element includes an arrangement for selecting a direction of movement of the tool or instrument which includes a closing device for cooperating with a resilient conjugate piece and a device for reversing a direction of movement of the closing device. The cooperation of the closing device with the resilient conjugate piece occurs in at least three states. In the first state, the fluid flows through the tubular element in a first direction; in the second state, the fluid flow is stopped in a direction opposite to the first direction of fluid flow; and, in the third state, the fluid is stopped in the first direction. The reversal device is adapted for holding the closure device either in the first and second state while excluding the third state, or in the third state.

Abstract: In drilling a well, sections of casing are run down a borehole, preferably with a float shoe at the lower end which is equipped with a double valve enabling the casing to fill with drilling mud both while the casing is moving down and also while it is stationary. Within the casing is a baffle collar which defines a socket for a latching dart carried by a plug. The plug and dart are driven down to the collar, when the pumping of cement into the casing has been completed, by a launching dart which also closes the passageway through the plug.

Abstract: For use in a drilling string including drill collars, a safety joint which enables the string of drill pipe to be unthreaded from the drill collars at the safety joint is disclosed. A safety joint utilizes a collet telescoped within and threaded to an outer tubular member connected in the drill string. They are held together by a releasable lock pin which is inserted and retracted to thereby enable the drill string to be separated at the safety joint so that remedial steps can be taken to free the remainder of the drill string. The safety joint is also capable of being actuated mechanically under control from the surface.Particular valve and signal receivers are disclosed herein including frequency responsive structural components which vibrate on being inflicted with a particular ultrasonic signal. The vibratory components oscillate and thereby initiate leakage of hydraulic oil from a pin locking system. Several alternate forms are disclosed.

Abstract: Disclosed is a surface controlled subsurface safety valve adapted to be landed in a dual line landing nipple. The safety valve is used to control well fluids conducted through the bore of a well tubing string. The valve has a control fluid pressure chamber and a balance pressure chamber along with a zone in the valve exposed to balance fluid pressure. The control fluid pressure chamber is interspersed between the balance fluid pressure chamber and the balance pressure zone, and has a system of seals associated therewith, that provide a fail-closed safety system. Tubing bore pressure, in the event of seal failure, enters the balance pressure chamber, causing the safety valve to close. This abstract of the disclosure is neither intended to define the scope of the invention which, of course, is measured by the claims nor is it intended to limit the invention in any way.

Abstract: A self-propelling apparatus for well logging tools includes a housing which is secured to the housing of a well logging tool and which defines a cylinder. A piston is slidably received in the cylinder, and a powder charge is mounted in the housing for electrical actuation. The cylinder is initially filled with a weighted fluid to establish a negative buoyancy whereby the well logging tool moves downwardly in a well to effect a logging operation. Upon completion of the well logging operation, a signal from the well logging tool actuates the powder charge whereby the piston forces the weighted fluid out of the cylinder and thereby establishes a positive buoyancy. This positive buoyancy together with the flow of the weighted fluid and the flow of gases resulting from the burning of the powder charge out of the housing combine to propel the well logging tool upwardly. At the top of the well the apparatus is siezed by latching apparatus and is retained thereby for subsequent retrieval.
