Sintef test of Ultralube II
- Friction tested by Statoil using a modified
Bariod lubricity tester - Tested in Novatec mud, weight 1.60 SG
- Tested in Glydril field mud, weight 1.60 SG
- Tested Ultralubes ability to stay on the steel

Conclusions for Novatec test
- Friction reduction with 4.95g/100ml (3.1
weight/weight ) average 38 - Friction reduction with 3.74g/100ml (2.3 w/w )
average 34 - Reduced average friction factor from
- 0,184 to 0,114

Comparison to Sintef Tests in Water based Mud
- Friction factor for the four best commercial
lubricants (0.15 - 0.18) in 1.44 SG mud. - The best polymer beads reduced friction from 0.20
to 0.11-0.13 - Friction reduction 27 with Ultralube II, down to
0.143. Mudweight 1.60 SG - Proved lubrication effect after lubricant was
removed from mud and until it was mechanically
worn off from lubrisimeter.
