Best Time Wins the RACE CONTRACT!

Service Companies = Coaches

Manufacturers = Runners

We all want to be on your team but

Service Companies must remember!

• Avoid Injuries (Failures)

• No Dropped Batons (Compatibility)

• Encourage Teamwork (Innovation)

Data Acquisition (1st Leg)

A Good Start is Key to Winning Any Race

Steering Sampling Rate ("StSR")Specifies the sampling rate, in data sets/second for steering data acquisitions.

This variable is always used in conjunction with "StST"

Steering Sample Time (“StST”)Specifies the sampling time, in seconds for steering data acquisitions.

Methods:

• Mud Pulse (+Pulse Position)

• ElectroMagnetic (EM)

• Mud Pulse (Frequency/Siren)

• Wired Drill-Pipe

• Acoustic, Light, etc.

Why haven’t we (as an industry) changed the

encoding in the past 20 years?

Faster Data Requires Faster Pulsers

Pulser Response Time:

• Solenoid – Limited In Charge Time To ~0.5 Pw

• Motor Driven

• Proven Capability Of 0.07 Pw (7.14 Bps) Decoded In Flow Loop

• Successfully Decoded 0.15PW To 20,000 MD TD With Dual Agitators

• Regularly Running 0.25PW To TD (Performed With BT, HPC, RIME)

Innovations In The Space Pushing Mud-pulse Speeds:

• Bench-tree : Modified Pitch Of Their Ball-screw Enabling A Faster Response

• RIME : Drives A Petal (2-port/4-port) Which Increases Speed

• APS Technology : 8-blade Rotary Pulser Decreases Open To Close Timings

• Others (Newer Designs) Aggressively Attacking Speed!

Faster Data Requires a Revised Maintenance Program

Common maintenance cycle:

• Rebuild lower-end every 100 hours.

• Re-oil Pulser every 250 hours.

Does this still hold?

100 hours @ 1 Sec PW 7,000 pulses

100 hours @ 0.25 Sec PW 28,000 pulses

Faster Pulse Width Means Tighter Time Windows

• Sample Transducer Faster

• 10-50 Hz EDR Systems

• 50-200 Hz Common in Decoding Systems

• 2000 Hz Capable Systems 0.25 PW

Why is detection better today?

• Access to stronger PC’s (RAM, Processor)

• Access to faster sampling hardware

• Access to stronger algorithms• Adaptive Filtration (Smart-filters)• RAID Detection, forward+backward• Machine Learning

• Dual Transducers (sample rate hardware)• Pulse Direction Can Be Determined

Conclusion

▪ The winning times of today are the losing times

of tomorrow. Things change.

▪ The race is the same, but runners are getting

stronger and faster.

▪ Continuing in the comfort zone will no longer be

enough to win

▪ Innovation comes in all forms and sizes.

Assemble the right team and special things will

happen.
