Claim:
1. A method of obtaining real-time data relating to a well construction activity, the method comprising the steps of: running wellbore-lining tubing into a wellbore as releasably coupled to a tubing string that extends to a well surface location, wherein the wellbore-lining tubing provides a non-magnetic tubing section, and wherein a magnetic field generating device and a fluid pressure pulse generating device are mounted to the tubing string; positioning the wellbore-lining tubing in the wellbore at a desired location; measuring a downhole parameter at the desired location external of the wellbore-lining tubing using a sensor mounted to the non-magnetic tubing section; releasing the tubing string from the wellbore-lining tubing and advancing the tubing string into the wellbore-lining tubing; positioning the magnetic field generating device within the non-magnetic tubing section and activating the magnetic field generating device to inductively couple the magnetic field generating device to the sensor; transmitting data relating to the downhole 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 sensor to the well surface location using the fluid pressure pulse generating device.
