While LWD is uncommon on the JR, it is extremely common on oil rigs and some of the crew members have backgrounds in the oil industry and are well-versed in the operational procedure.

Other than drilling speed and pump rate limits, the set up and procedure for LWD is no different than regular drilling for the rig crew and driller. The pumping provides power to the tools located just above the bit and the tools send data in the form of sound waves up the pumping column. Otherwise the initial set up is with the LWD tools rather than with drilling pipe alone. If the seafloor sediment is expected to be soft, a camera is sent down to determine an accurate seafloor elevation.

The important things are to make sure the hole is straight, so the LWD engineers who manage the tools keep a close eye on the pressure and inclinometer readings. I was also curious about why LWD is important for the science objectives for expedition and had the opportunity to ask LWD team leader Dr. Ann Cook. Check out her interview below:. Known as "intelligent drilling," use of real-time logging information provided by LWD is enabling stronger, more successful wells both onshore and off.
