Ilmenite

Ilmenite was used in drilling operations in the North Sea in 1979 and 1980. The ilmenite was a fairly coarse ground material compared to the presently used ilmenite. The drilling fluid properties were easier to control compared to drilling with barite. Again, this was because ilmenite has a lower tendency of being ground down to finer particles.
