Radial ball injecting apparatus for wellbore operations
An apparatus for successively releasing balls into a wellbore during wellbore operations is disclosed. The apparatus has a radial housing having at least one radial ball array having two or more radial bores. Each radial bore houses a ball cartridge adapted to receive and release balls and an actuator for operably aligning or misaligning the ball cartridge with an axial bore in fluid communication with the wellbore. The ball cartridge is moveable along the radial bore and is operable between an aligned position, for releasing a ball and a misaligned position for storing the ball.
Method, apparatus and a system is provided for dry launching balls. One releases a ball from the stored balls, stages the ball in a staging or launching block for exposure to fluids and then injects the dropped ball into the wellbore. Fluid in the isolated staging block is removed by pump or by drainage, minimizing risk of fluid reaching stored dry balls thereabove. This method can then be repeated for subsequent balls to be dropped into the wellbore. Further, a system for reducing the fall energy of a dropped ball comprises providing one or more impact energy dampeners along a ball drop path including providing an angled sidewall of the path bore, one more elements to periodically engage a dropped ball, or to provide a liquid sump to receive a dropped ball.

A system and method are provided for storing and dry launching one or more balls into a wellbore having reduced ball drop height and ball drop stages relative to existing systems and methods. Balls are individually stored in cartridges of a ball launcher in communication with the wellbore via an axial bore, and are isolated from fluids and pressure in the axial bore by seals located on the cartridge. A selected ball can be injected into the wellbore by isolating the axial bore from the wellbore, establishing a launching pressure in the axial bore, actuating the cartridge of the selected ball to a launch position to stage the ball in the axial bore, retracting the cartridge to a sealing position, establishing a release pressure in the axial bore, and then re-establishing communication between the axial bore and wellbore to allow the ball to be injected.

Method, apparatus and a system is provided for injecting carrier sleeves into a wellbore. A selected carrier sleeve is aligned in an injector bore restricted therein from free fall and preventing a subsequent sleeve from indexing into the bore from a magazine of sleeves.

The staging bore is fluidly isolated from the injector bore. The pressure in the staging bore is equalized with the wellbore and then opened to the wellbore for launching the sleeve. The staging bore can be isolated from the injection bore by valve or isolation mandrel sealably moveable within the axial bore.
