GOOD INFORMATION IS A CORNERSTONE 5
Is Our Drilling Data Good? • Quest stio ion n 1 — Is it a problem we need to address or is magnitude of error lost in the noise • Quest stio ion n 2 — If 1 is true, how significant are the errors • Quest stio ion n 3 — If 2 is high, can we even fix it? 6
QUESTION 1 IS ERROR > NOISE AND IS IT IMPORTANT?

SHARED FIELD OBSERVATIONS FROM ~10 DIFFERENT RIGS • Hookload is generally over-reported by hydro- mechanical gauges. ˃ This means we get less WOB than we think • Torque is generally over over-reported by flux output of VFD ˃ This means we get less torque than we think 14 14

QUESTION 3 CAN WE FIX IT? YES WE CAN!
NEW TOOLS ARE NEEDED • Had to use new tools when old ones did not satisfy requirements ˃ TTS to Measure Torque and Hookload • Had to invent new tools when none existed ˃ Iron Roughneck Calibration Tool • Recommended new types of tools when calibration is not practical with current tools ˃ Radar Pit Level Sensors ˃ Coriolis meters 28 28
CAN WE CALIBRATE EXISTING TOOLS? Rig F TOP-DRIVE WAS CALIBRATED TO MATCH TTS SUB 29 29
