  • High resolution continuous depth positioning in a well bore using persistent casing properties
    Patent number: 9540927
    Abstract: Continuous measurement indicia between casing collars of a pipe segment of a well bore casing is obtained from signals obtained by sensing innate, persistent and unaltered characteristics, e.g. magnetic permeability, of the pipe segment along its length, and using the signals to perform a downhole function, e.g. a gravity measurement, at an indicated location.
    Type: Grant

  • Continuous gravity survey of a borehole
    Patent number: 8594937
    Abstract: Gravity measurements from a borehole gravity survey are obtained by continuously moving the gravity meter within the borehole. Movement-induced acceleration errors are quantified and subtracted from the gross measurements from the gravity meter to obtain actual gravity values at a multitude of measurement points within the borehole. Acceleration errors are calculated from the second differential of the true vertical depth of the gravity meter, which is computed measured length and weight and elongation characteristics of a cable which suspends the gravity meter in the borehole, upper and lower tension measurements in the cable, and the topography of the borehole.
