1. VEN-LUBE II
A SPECIALIZED “SEALING” LUBRICANT

2. VEN-LUBE II
A drilling fluid lubricant used in water based
mud systems
Nonpolluting
Readily biodegradable
Solid
Nontoxic
(LC50 on Mysid Shrimp = 960,000 ppm)

3. VEN-LUBE II
Is primarily a “solid” drilling fluid lubricant
Has good secondary properties for seepage
loss control
Novel in that it filters and concentrates in
the wall cake where a lubricant is needed

4. VEN LUBE II PATENT
U.S. Patent No. 4,356,096
Assigned to Venture Chemicals, Inc.

5. What Is
VEN-LUBE II?
Surface modified,micronized
cellulose fibers, which
have been pre-treated with
an environmentally safe,
oil lubricant

6. VEN-LUBE II
Allows the lubricant to be carried to and
concentrated in the wall cake as the fibers
are filtered

7. VEN-LUBE II
The cellulose fibers provide the additional
property of seepage loss control in depleted
sands where di erential sticking is a
potential problem.

8. VEN-LUBE II
Benefit:
The ability to place the lubricant into the
interface area of the borehole where it will
provide the most benefit

9. VEN-LUBE II
Will concentrate into
the critical interface
between the formation
and the mud column.

10. APPLICATIONS
Elimination of Di erential Sticking
Problems

11. APPLICATIONS
Control Of Torque & Drag Problems

12. APPLICATIONS
E ective in Freeing Stuck Pipe when
Mixed with Oil or Spotting Fluids

13. APPLICATIONS
Wall Cake Conditioner
– Reduces Surface Permeability
– Increases Strength
– Increases Flexibility
– Reduces Thickness

14. APPLICATIONS
Reduces Collar & Stabilizer Balling

15. ECONOMICAL
Seepage Loss Additive

16. TREATING METHODS
Pretreatment: 4-8 lb/bbl to entire systems
Periodic slug treatments: 10-30 lb/bbl
High liquid loss LCM pills: 80-100 lb/bbl
Hole Sweeps: 10-30 lb/bbl

17. E ect of Heat Aging on the Sealing
Characteristics of VEN-LUBE II
125 lb/bbl Slurries of VEN-LUBE II were hot-rolled
In Tap water at 400 o F
After hot-rolling 84 ml of aged VEN-LUBE II were
to 235 ml of prehydrated bentonite slurry

19. VEN-LUBE II
Utilized in most drilling areas
throughout the world

20. Case History
Location: O shore Louisiana
Depth, ft.: 5,100' vertical depth with angle built at 4° per 100' to a
total angle of 65 o
Problem: Excessive Torque and Drag
Solution: Utilize 3 lb/bbl of VEN-LUBE II through the Mud
System. In addition, occasionally a 25 lb/bbl (25 bbl)
sweep was run.
Results: Well was logged and casing was set with minimal
torque and drag. As a result, the operator has decided to
incorporate VEN-LUBE II into the mud program of all
future wells as a preventive measure.

21. Case History
Location: Upper TexasGulf Coast
Depth, ft.: 12,300
Problem: Low pore pressure, Frio sand formation at 12,300 (As
determined by 2 reference wells in the area.)
Solution: Utilize 20 lb/bbl sweeps of VEN-LUBE II. In addition,
a 40 bbl sweep as soon as the sand was encountered,
and 40 bbl sweep after drilling through the problem
sand area.
Results: Successfully drilled through the problem sand
area.A dynamic leak-o test to 17 ppg. Equivalent was
then run. Pressure and circulation was maintained for
ten minutes with no loss of mud. Normal drilling was
continued. The mud was weighted up to control pore
pressures encountered.

22. Case History
Location: Upper Texas Gulf Coast
Depth, ft.: 11,525
Problem: Di erential Sticking while making a connection. Three
joints of drill pipe and eight drill collars were left in
hole.
Solution: Utilize 10 lb/bbl sweep of VEN-LUBE II (25 bbl pills)
during washover operations. In addition, 25 bbl sweeps
per tour while drilling to prevent future problems
Results: Drill string was recovered. Sweeps were run for 3 days
with no problems. After the sweeps, of VEN-LUBE II,
were discounted the pipe became stuck at 11,782’.
Once the pipe was jarred free, sweeps were reinstated
and the well was drilled to T.D. (13,000’) without any
further di culties.

23. VEN-LUBE II
Summary

24. Summary
Ven-Lube II is a novel, nonpolluting, solid drilling fluid
lubricant used in water based mud systems.
Ven-Lube II can reduce hole problems:
– Lubricity
– Seepage loss/Fluid Loss
– Stuck pipe
– Wall Cake Conditioner
Improve your next well profitability
