What does mud do?
• Clean the
wellbore
• Provide wellbore
stability
• Controls
downhole
pressures
• Provides lubricity
for drill string

Low solids
What does mud look like?

6. 7 6/25/14 Confidential Information © 2011 M-I SWACO
What does high solids look like?
Laminar Transitional Turbulent
Carrying Ability
Pressures

7. 8 6/25/14 Confidential Information © 2011 M-I SWACO
What does this data look like?
Slope = Solids Control Efficiency

8. 9 6/25/14 Confidential Information © 2011 M-I SWACO
How do we control this curve
Solids Control Efficiency
How efficient are the shakers at removing
solids from the fluids?

9. 10 6/25/14 Confidential Information © 2011 M-I SWACO
New Method
Slope = Solids Control Efficiency

So what?

11. 12 6/25/14 Confidential Information © 2011 M-I SWACO
Now what?
To get to 23%
1. Use finer screens to increase our efficiency
2. Retire screens once they are past their service life
But wait lets turn it up to 11!
Lets observe the performance
of the solids control
Rig Evaluation!

Rig Evaluation? - What is that?
A rig Evaluation is an assessment of the Rig’s
strengths and weaknesses. It also assess the
performance of secondary solids control:
