Refreshing MWD Technology

Models Vs. Reality

5

Why Models?

- To maximize ROI

- To maximize ROI

- To maximize ROI

Market Approach:

- Experts from various disciplines pick a subject and optimize/model it

- Fluid/Hydraulics

- ROP/MSE optimization

- Hole Cleaning, etc.

Questions Asked When Evaluating Model Effectiveness:

▪ Did the <Insert Model Name Here> perform as expected?

▪ Did the equipment I’m using execute my plan as modeled?

▪ Can we quantify our model’s performance?

▪ Did we save money?

▪ How much money are we saving?

6

Models Vs. Reality

What about questions we fail to ask?

▪ Was the optimization of a single workflow counter productive to other processes?

▪ Are we still saving money?

▪ Is there more than one Reality?

7

Models Vs. Reality

Example Model – Hole Cleaning

8

Model Inputs - Depth, Mud (Viscosity, Weight, wall

thickness, etc,) Casing, Drill String

OD/ID, Mud Weight, Overpull, etc)

- Executing Model Recommendations- Circulation Time

- Circulating Speed

- Pipe Movement Profile

Clean Hole!

Hole Cleaning Reality Vs. MWD Reality

51.1 Circulating Hours

▪ 1 Hr @ 25-35G Peak Lateral Shock

▪ 7.2 Hr @ 25-30G Peak Lateral Shock

▪ 10.6 Hr @ 20-25G Lateral Shock

▪ 0.8 Hours @ 8-gRMS

Hole Cleaning Reality - Impact on MWD Equipment

Hole Cleaning

Drilling

14

Two Profiles– Different Impacts on ROI

15

Less Shock & Vibration = Less Tool Failures

16

Staging RPM – Measuring Impact

17

Extreme BHA Disfunction (Well Model failure?)

18

Conclusion

▪ New technology is pushing the limits of drilling

▪ Don’t lose focus on the goal: Maximizing ROI.

▪ Our models need updating. [Clean Hole] + [Broken Tool] ≠ Maximum ROI.

▪ Evidence shows we can have our cake and eat it too if we correctly identify the relationship between our various drilling models

▪ Alternate realities do exist
