  • Publication number: 20200217160
    Abstract: An agitator for vibrating a drill string includes an agitator housing, a rotor and an agitation mass. The drill string has a central axis. The rotor is coupled to the agitator housing and being rotatable about an agitator axis. The agitation mass is coupled to the rotor and is rotatable about the agitator axis.

  • Publication number: 20200190957
    Abstract: A system and method for controlling a drilling tool inside a wellbore makes use of projection of optimal rate of penetration (ROP) and optimal controllable parameters such as weight-on-bit (WOB), and rotations-per-minute (RPM) for drilling operations. Optimum controllable parameters for drilling optimization can be predicted using a data generation model to produced synthesized data based on model physics, an ROP model, and stochastic optimization. The synthetic data can be combined with real-time data to extrapolate the data across the WOB and RPM space. The values for WOB an RPM can be controlled to steer a drilling tool. Examples of models used include a non-linear model, a linear model, a recurrent generative adversarial network (RGAN) model, and a deep neural network model.

  • Publication number: 20200173269
    Abstract: A system for real-time steering of a drill bit includes a drilling arrangement and a computing device in communication with the drilling arrangement. The system iteratively, or repeatedly, receives new data associated the wellbore. At each iteration, a model, for example an engineering model, is applied to the new data to produce an objective function defining the selected drilling parameter. The objective function is modified at each iteration to provide an updated value for the selected drilling parameter and an updated value for at least one controllable parameter. In one example, the function is modified using Bayesian optimization The system iteratively steers the drill bit to obtain the updated value for the selected drilling parameter by applying the updated value for at least one controllable parameter over the period of time that the wellbore is being formed.

  • Patent number: 10669845
    Abstract: Tubular stretch correction for different operational conditions is applied to determine tubular wear volume. The tubular stretch correction is applied as a function of a stretch factor comprising a varying shift factor, axial load on the tubular string, pressure effects on the tubular string, buckling of the tubular string and/or temperature effects on the tubular string. Stretch factors are taken into account to determine the correct position of wear factors along the casing string, which are ultimately used to determine the casing wear volume.

  • Patent number: 10570703
    Abstract: System and methods for monitoring casing wear for a well during a drilling operation are provided. Casing design parameters for a planned well are determined during a planning phase of the drilling operation. A wear factor along a length of the planned well is computed based on the casing design parameters. A casing wear map is generated based on the computed wear factor along the length of the planned well relative to one or more of the casing design parameters. The generated casing wear map is visualized via a display of a computing device. The visualized casing wear map enables a user of the computing device to estimate casing wear for the planned well and determine an appropriate casing design for the planned well based on the estimated casing wear.

  • Publication number: 20200011146
    Abstract: This disclosure provides an agitator system that includes an agitator assembly of concentric power-sections, (one power-section inside another power-section both of which comprise stators and rotors). The agitator system includes a controller configured to control a valve assembly of the agitator assembly to selectively open and close the valve assembly to allow fluid to selectively flow between the power-sections of the agitator assembly that generates pressure fluctuations or pressure pluses in the fluid pressure, which increases the speed of the rotor or rotors, and thus, the vibrational frequency of the agitator. The controller can be used to increase the vibrational frequency of the agitator assembly when necessary to prevent the drill string from becoming lodged in a wellbore.

  • Patent number: 10428639
    Abstract: Damage to a casing string in a wellbore resulting from a wellbore operation can be predicted. For example, a stiff string model can be used to determine a contact point between the casing string and a well tool positionable within the casing string for performing the wellbore operation. The stiff string model can be used to determine a force of the well tool against the casing string at the contact point. The force can be used to determine a volume of damage to the casing string proximate to the contact point. A depth of a groove formed in the casing string proximate to the contact point can be determined based on the volume of damage.
