Monitor current rig operations, paying particular attention to nature of bottom hole assembly in the hole (slick, stiff, pendulum, directional, etc.).

Although this is a drilling matter, the remote geologist must understand all operations, and recognize any deviations from the drilling program.

If any deviations are observed, Client’s personnel are notified as per protocol.
