Patents by Inventor Kees Langeveld

Kees Langeveld has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Drill bit instrumentation and method for controlling drilling or core-drilling
    Patent number: 5720355
    Abstract: Bit instrumentation and method for controlling drilling are disclosed that include multiple resistivity sensors 5B and accelerometer sensors 4 disposed within an insert portion 1B of the drill bit 1. The resistivity sensors have a beveled portion to provide an interference fit with a cavity formed within the insert portion 1B of the drill bit. Resistivity sensors 5B may be used to determine the motion of the bit 1 within the wellbore 106 including unstable bit operation such as bit whirling and bit tilting. As well, accelerometer sensors 4 may also be provided in conjunction with the resistivity sensors 5B to provide information concerning motion, accelerations and stresses applied to or within the drill bit 1.

  • Method for controlling the head of a drilling or core-drilling device and apparatus for carrying out this method
    Patent number: 5501285
    Abstract: Electrodes are provided in a drill bit, or alternatively, in a coring bit, to measure variations in formation resistivity surrounding an earth borehole. Three orthoganal accelerometers are also provided in the drill bit, or in the coring bit, to monitor the dynamic behavior of the bit as functions of radial, axial and tangential accelerations.
