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).
