  • Patent number: 10774637
    Abstract: Systems and methods are disclosed that provide highly accurate and controllable measurements of rock formation properties in a wellbore. The systems and methods utilize a prescribed input signal to mechanically perturb a drill string in contact with a rock formation in order to elicit a mechanical response. Based on the input signal and the mechanical response, a transfer function is computed and analyzed, wherein the analysis uses estimates of the drill string resonances to identify rock formation resonances, which are used, in turn, to determine the rock formation properties.

  • Publication number: 20200024901
    Abstract: Techniques are disclosed which acts to maintain a drillstring in dynamic friction during geo-steering operations when the drillstring is not rotating. Embodiments of the invention include a drilling system having a drillstring coupled to a top drive or a kelly, and a method of estimating a frictional torque along the drillstring to compute an oscillatory rotary input to the top drive or the kelly based on an input period or amplitude received at a human machine interface. A rotary control signal based on the oscillatory rotary input is transmitted to the top drive or the kelly via a variable-frequency drive (VFD) motor control system. The drillstring can be further coupled to a sensor and the feedback from the sensor can be monitored for proper operation to adjust the oscillatory rotary input during the geo-steering operations.

  • Patent number: 10185306
    Abstract: A method, system and computer program product for utilizing look-up tables representing all models in an automation control architecture to independently handle uncertainties in sensed data. Data is stored in a form of conditional probability tables (CPTs) or conditional probability distributions (CPDs), where the data comes from an operator, a service provider, a drilling contractor and an equipment manufacturer. Models of the drilling process domains, such as wellbore hydraulics, drill bit/rock interactions, torque and drag modeling, vibration modeling and drilling machinery operation, are received. Data is extracted from these models into the CPTs or CPDs. The CPTs or CPDs are converted to look-up tables. Data in the look-up tables are then visually displayed in graphical form. As a result, real-time troubleshooting of drilling operations occurs in an efficient manner.
