Gravity tool face
WebMore particularly, this invention relates to the use of gravity measurement sensors, such as accelerometers, to determine a change in tool face between first and second longitudinal positions... WebThe angle of inclination and gravity tool face are calculated from the signals of the accelerometer. Due to its operation being based on the angular velocity of the Earth and not on magnetism, Navibore™ technology has multiple applications in geology, civil engineering, mining, oil and gas. How to ensure project success?
