The present invention provides a casing connection device allowing both bending and rotating motion and that provides three separate sealing areas for leak prevention.
E21B 17/042 - CouplingsJoints between rod and bit, or between rod and rod threaded
F16L 19/02 - Pipe ends provided with collars or flanges, integral with the pipe or not, pressed together by a screwed member
F16L 25/00 - Construction or details of pipe joints not provided for in, or of interest apart from, groups
F16L 27/113 - Adjustable jointsJoints allowing movement comprising a flexible connection only the ends of the pipe being interconnected by a rigid sleeve
The present invention provides a casing connection allowing both bending and rotating motion. The casing connection has a top face sub, a bottom face sub, an adjusting collar threadably connecting said top face sub to said bottom face sub; and three sealing areas formed at connections between the top face sub, the bottom face sub and the adjusting collar for leak prevention. The degree of bending and rotation of the casing connection is controllable by tightening or loosening said threadable connection of said adjustable collar.
A top drive-pumpable cement head is provided for cementing a casing into a wellbore comprising a top sub portion with a top drive connection connectable to a top drive shaft to receive cement and impart translational and rotational forces to the casing simultaneously during cementing, and a ball launching assembly for housing and launching one or more launching balls. A bottom sub portion comprises a casing sleeve for housing one or more hollow wiper plugs and a tattle tale wire. The cement head also comprises a hammer union. The ball launching assembly is pre- loadable with the launching balls, the bottom sub is pre- loadable with the one or more hollow wiper plugs and a tattle tale wire and the top sub and the bottom sub are connectable via the hammer union for storage, prior to cementing operations. A method is also provided for assembling a cement head for completing a casing in a wellbore.

A device is provided for delivering and distributing injection fluids into a subsurface formation from a horizontal wellbore. The device includes one or more steam pups having an outer sleeve and an inner sliding sleeve in concentric relationship. One or more sets of nozzles are arranged on the outer sleeve. A means is provided for actuating movement of the inner sliding sleeve within the outer sleeve, to at least partially cover one or more sets of nozzles on the outer sleeve. A method is also provided for delivering injection fluids into a subsurface formation from a horizontal wellbore. First, one or more steam pups are introduced into the horizontal well, said steam pups having an outer sleeve and an inner sliding sleeve with one or more sets of nozzles arranged on the outer sleeve. Next the inner sliding sleeve is moved inside the outer sleeve to at least partially cover one or more sets of nozzles on the outer sleeve. Finally, injection fluid is injected through the steam pup nozzles into formation. A further method is provided that comprises introducing into a heel location of the wellbore a first and second pairs of flow control hangers and polished bore receptacles, connected to an intermediate casing and cemented in place. The the first pair of flow control hanger and polished bore receptacle are connected to an injection/prodcution liner and one or more steam pups are then connected to the second pair of flow control hanger and polished bore receptacle.
