ULTRALUBE II

1

• ULTRALUBE II
• Lubricant for Drilling Muds, Brines, Diesel and
  Crude Oil.

2
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.
