  4. ERD Campaign Challenges • High angle wellbores • Wellbore instability • Hole cleaning • NPT risking economic viability

  5. Current Telemetry System Desired Outcome Mud Pulse Data transferred in 2-5 sec pulses • High angle wellbores • Wellbore instability • Hole cleaning • NPT risking economic viability Sequential data Reduce geological uncertainty Identify bedding-related instability Annular pressure measurements Risk mitigation, redundancy 10 bits/sec Gamma Vibration Resistivity Pressure

  6. Broadband Drillstring Technology Mud Pulse Mud Pulse Networked Drillstring Data transferred in 2-5 sec pulses Continuous bi-directional data transfer Sequential data Reduce geological uncertainty Identify bedding-related instability Annular pressure measurements Risk mitigation, redundancy 10 bits/sec Simultaneous data 57, 600 bits/sec High bandwith High defention Highvolume Real time Tool actuation Gamma Vibration Resistivity Pressure NMR Sonic Seismic Etc., etc. Vibration Image logs

  7. Broadband Drillstring Technology 1) Armored coax cable 2) Induction coils 3) Boosters

  8. Broadband Drillstring Technology Mud Pulse Mud Pulse Networked Drillstring Data transferred in 2-5 sec pulses Continuous bi-directional data transfer Sequential data 10 bits/sec Simultaneous data 57, 600 bits/sec High bandwith High defention Highvolume Real time Tool actuation Gamma Vibration Resistivity Pressure Networked Drillstring 320 ft/hr 2 pts/ft –16 sector Image log in HD Mud Pulse 60 ft/hr 1 pt/ft –4 sector Image log “averages out” breakout. NMR Sonic Seismic Etc., etc. Vibration Image logs

  9. First Well Highlights Courtesy of Baker Hughes • Fault imaging at 100ft/hr in 17 ½” hole – Modifying well trajectory • Dip picking in real time – Improving structural understanding • Stick slip in real time – Modifying drilling parameters and extended hole section • Tool memory filled Up • Wellbore breakout imaging – Caliper in real time • Diagnosed sensor failure – Drilling Ahead • Conclusion: More data saves time to interpret
