Summary:

  • Gravitational attraction
    • Gravity constant
  • Gravity strength around the world
    • Flat earth
    • Round earth
    • Real earth shape – satellite image?
  • How we measure gravity
    • Lab / calibration
    • Down hole
    • Difference between gravity and movement of sensor (none)
  • Why TGF QC is important
    • Effect of scale factor error
    • Effect of bias error
    • Effect of movement
    • Effect of gravitational waves
  • Effect of movement error
    • on inclination
    • On azimuth
  • Proposed solution
    • Calibrate to standard gee
    • Survey companies who do this already
    • Reminder to ensure that tools in transition are identified

Talking Points:

  • Newton – which way is down?
  • We measure acceleration not “g”
  • Flat Earth Society – constant “g”
  • Modern view of Flat Earth from Space
  • United Nations supports this view
  • Round Earth theory
  • Newton - gravitational attraction
  • Non-gravitational attraction
  • Gravital Variations
  • Gravitational Waves
  • “g” calculation at Equator
  • General local “g” calculation
