Abstract:
A fill-up and circulation tool includes a mandrel; a packer assembly is disposed around the mandrel; and a valve assembly connected to the mandrel, wherein the valve assembly is configured to selectively control fluid flow into the tool and out of the tool.
Abstract:
The present invention generally relates to an apparatus and method for compensating a landing string due to movement of a floating rig platform. In one aspect, a compensation system for use with a landing string is provided. The compensation system includes a slip joint member attachable to the landing string, the slip joint member having an upper portion and a lower portion. The compensation system further includes a first lock assembly configured to connect the upper portion of the slip joint member to a floating rig. Additionally, the compensation system includes a second lock assembly configured to connect the lower portion of the slip joint member to a riser disposed below the floating rig. In another aspect, a method for compensating a landing string due to movement of a floating rig is provided.

The present invention generally relates to an apparatus (100) and method for compensating a landing string (50) due to movement of a floating rig platform. In one aspect, a compensation system for use with a landing string is provided. The compensation system includes a slip joint member attachable to the landing string, the slip joint member having an upper portion and a lower portion. The compensation system further includes a first lock assembly configured to connect the upper portion of the slip joint member to a floating rig. Additionally, the compensation system includes a second lock assembly configured to connect the lower portion of the slip joint (20) member to a riser (40) disposed below the floating rig (5). In another aspect, a method for compensating a landing string due to movement of a floating rig is provided.
Abstract:
A fill up tool includes a mandrel; a primary sealing member disposed around the mandrel; and a selectively operable secondary sealing member activated by rotation of the mandrel. In another embodiment, the selectively operable secondary sealing member is activated using hydraulic pressure.

A fill -up and circulation tool (100) includes a mandrel (105); a packer assembly (150) is disposed around the mandrel; and a valve assembly (200) connected to the mandrel, wherein the valve assembly is configured to selectively control fluid flow into the tool and out of the tool.
Abstract:
A conventional mud saver valve (9) used to inhibit leakage from fill tubes (7) onto the working platform while new stands of casing are being fitted is replaced by a valve having a metal valve member (109') and a vulcanized rubber seat (120). In addition, a pressure gauge (128) is fitted to the cover (2) of the filling and circulating head (1) to detect excess pressure after circulation. A part (210) is also provided to release the filling and circulating head (1) from 'lock-up'. Further described is an extension sub which is installed above the filling and circulating head (1) to prevent 'lock-ups' of the top drive (6) fixed to elevator (13). The sub is locked in an extended position by hydraulic fluid in a lower chamber. In the case of a 'lock-up' the fluid is released into an upper chamber so that the length of the sub is shortened. The top drive can be lowered with respect to the casing (12) to release the elevator (13).
