A method of predicting behavior of a drilling assembly includes: generating a mathematical representation of a geometry of each of a plurality of components of a drilling assembly, the plurality of components including a plurality of cutters and one or more additional components configured to at least one of: support the plurality of cutters and operably connect the plurality of cutters to the drill string, the one or more additional components including a drill bit crown; simulating one or more operating conditions incident on the drilling assembly representation, and simulating an interaction between the plurality of components and an earth formation; and predicting physical responses of the drilling assembly representation to the one or more conditions.

Modeling and simulation of complete drill strings

An apparatus for reducing vibration includes a damping assembly configured to be fixedly attached to a downhole component. The downhole component is configured to rotate within a borehole in an earth formation, and the damping assembly has a damping frequency that is tuned relative to a selected natural vibration frequency of the rotating downhole component to reduce vibration due to component rotation.

Mitigation of rotational vibration using a torsional tuned mass damper

A method for estimating drilling parameters for drilling a borehole in the earth includes: drilling the borehole with a drill string having a mud motor and a drill bit; constructing a mathematical model of a system including the drill string, the mud motor, and a borehole geometry; calculating a mud motor lateral excitation force imposed on the drill string by the mud motor for one or more combinations of drill string rotational speed and mud motor rotational speed; calculating lateral motion of the drill string and a force imposed on the drill string at positions along the drill string for the one or more of combinations using the model and the excitation force; selecting a range of combinations of drill string rotational speed and mud motor rotational speed that result in the force imposed upon the drill string being less than a threshold value; and displaying the range of combinations.

Method to predict, illustrate, and select drilling parameters to avoid severe lateral vibrations

A method of operating a drill string includes receiving signals indicative of rotation of a bottom hole assembly (BHA) of the drill string; receiving signals indicative of the torque experience by the BHA; determining from the received signals an average slipping torque and a maximum sticking torque; determining a friction ratio based on the maximum sticking torque and the average slipping torque; and generating an indication that the friction ratio exceeds a limit.

Drilling control system and method

A method for presenting drilling information includes presenting a display including a graph having a first axis and a second axis. The first axis represents a rate of penetration (ROP) of a drill bit into a borehole and the second axis representing a mechanical specific energy (MSE) of a drilling system that includes the drill bit. The method also includes plotting time based or foot based data with a computing device for one or more drilling runs on the graph and overlaying the graph with lines of constant power.
