Abstract: The invention relates to a method for obtaining real-time data relating to a well construction activity, and to a corresponding downhole assembly. The invention also relates to a downhole tool assembly for such a use. In one embodiment, a method of obtaining real-time data relating to a well construction activity is disclosed, the method comprising the steps of: locating wellbore-lining tubing (18) comprising at least one non-magnetic tubing section (38) in a wellbore (12) of a well; measuring at least one downhole parameter at a location (43) external of the wellbore-lining tubing using at least one sensor (40, 42) associated with the non-magnetic tubing section; positioning a magnetic field generating device (44) within the non-magnetic tubing section and activating the device to inductively couple the device to the at least one sensor; transmitting data relating to the at least measured parameter through the non-magnetic tubing section to the magnetic field generating device by means of the inductive coupling; and transmitting the data retrieved from the at least one sensor to surface using a fluid pressure pulse generating device (46) associated with the magnetic field generating device. A subsea connector assembly is provided for automatically coupling a movable subsea structure to a tubular fixed subsea structure. The connector assembly comprises a male connector assembly, removably mountable to the movable subsea structure, and further comprising a throughbore, at least one first actuator member and at least one second actuator member. The connector assembly further comprises an adapter assembly, removably mountable to an end-fitting of a string of tubulars, comprising at least one first engagement member and at least one second engagement member, each of said at least one first and second engagement member are operable to be acted upon by said first and/or second actuator member so as to selectively release a locked engagement with said male connector assembly, allowing said adapter assembly to be moved through said throughbore of said male connector assembly. The invention relates to a method for obtaining real-time data relating to a well construction activity, and to a corresponding downhole assembly. The invention also relates to a downhole tool assembly for such a use.
