20130146278 | BALL GRAB TUBULAR HANDLING - A casing running tool is provided having a central mandrel with spiral wedge grooves, an outer cage having generally horizontal slots corresponding to the spiral wedge grooves, and grabber balls disposed between the spiral wedge grooves and the horizontal slots. Each of the spiral wedge grooves has a deeper end and a shallower end, between which the respective grabber balls roll. When a grabber ball is disposed in the shallower end of the respective spiral wedge groove, the grabber ball exerts a radial force against an inner wall of a casing or liner being supported. In addition, the running tool facilitates the application of torque from the running tool to the casing or liner being supported. | 06-13-2013 |
20130146360 | RESONANT EXTRACTOR SYSTEM AND METHOD - A resonant extractor system configured to use rotational energy provided by a top drive system to apply vertical oscillating motion to attached tubular or drilling equipment. The extractor includes a rotational component, an oscillation component, and an assembly of engagement features. The top drive system may rotate the rotational component about a vertical axis. In certain embodiments, the rotational component is a housing, the oscillation component is a quill, and the engagement features include a cam disposed on a shaft. The shaft is coupled to and extends radially into the housing, and the cam disposed on the shaft, which features an eccentric geometry relative the shaft, maintains contact with a lip extending from the quill in the housing. As the housing rotates, the eccentric cam rotates, raising and lowering the quill, which is configured to couple with tubular or drilling equipment. | 06-13-2013 |
20130161965 | CIRCUMFERENTIAL CAMS FOR MECHANICAL CASE RUNNING TOOL - A casing running tool is provided having both axial and circumferentially tapered elements. In certain embodiments, the casing running tool comprises cam structures that are circumferentially tapered so as to allow an applied torque to engage and disengage the casing running tool with a casing or liner. In embodiments, the circumferential taper of the cam structures allows a mandrel or rollers disposed between the mandrel and cam structures to apply radial force to corresponding shoe structures which in turn engage or disengage the casing or liner. The cam structures may also exhibit an axial taper to allow for a self-energized fail-sage operation of the casing running tool. | 06-27-2013 |
20130168106 | PIPE DRIVE SEALING SYSTEM AND METHOD - Present embodiments are directed to a gripping device configured to couple with a pipe element. A housing of the gripping device is configured to extend over and at least partially around a distal end of the pipe element. Torsional clamp devices are configured to engage an outer circumferential surface of the pipe element with frictional engagement features that extend radially inward from the housing. A sealing mechanism is configured to shift a pipe seal relative to the housing and into engagement with the distal end of the pipe element and to facilitate fluid flow through the gripping device into the pipe element. | 07-04-2013 |
