  • Patent number: 11401798
    Abstract: A method of geosteering in a wellbore construction process uses an earth model that defines boundaries between formation layers and petrophysical properties of the formation layers in a subterranean formation. Sensor measurements related to the wellbore construction process are inputted to the earth model. An estimate is obtained for a relative geometrical and geological placement of the well path with respect to a geological objective using a trained stochastic clustering and pattern matching agent. An output action based on the sensor measurement for influencing a future profile of the well path with respect to the estimate.

  • Publication number: 20210388715
    Abstract: A method for determining a depth of a target layer in a subterranean formation involves obtaining sequences of downhole and offset data. The downhole and offset data are discretized, and labels assigned to the discretized data. The sequences of labeled downhole and offset data are compared to determine a subsequence alignment. A depth for the target layer can thereby be determined.

  • Publication number: 20210310347
    Abstract: A method for autonomous geosteering for a well-boring process uses a trained function approximating agent. A geological objective is determined. Then, using the trained function approximating agent, a sequence of control inputs is determined to steer a well-boring tool towards the geological objective. The trained function approximating agent is adapted to enact the sequence of control inputs upon receiving a signal from a measurement from the well-boring process.

  • Publication number: 20210312332
    Abstract: A method for producing a simulation environment for training a function approximating agent uses an earth model that defines boundaries between formation layers and petrophysical properties of the formation layers in a subterranean formation. A toolface input corresponding to a set of model coefficients produced by the earth model is provided to a drilling attitude model, which produces a drill bit position. The drill bit position is fed to the earth model for determining an updated set of model coefficients for a predetermined interval and a set of signals representing physical properties of the subterranean formation. The signals are provided to a sensor model to produce at least one sensor output. A reward is determined from the sensor output. The simulation environment for training the function approximating agent can be used for automating a geosteering process.

  • Patent number: 9835020
    Abstract: A drilling tool in accordance to one or more aspects includes a processor and a steering device. The processor determines a demand attitude and an instantaneous drilling tool attitude, evaluates a control law to derive a control law tool face, and converts the control law tool face to an equivalent tool face. The steering device applies the equivalent tool face to control a drill attitude of the drilling tool.

  • Publication number: 20150330209
    Abstract: A feedback control system for steering a tool along a well-plan. Optimum steering instructions may be generated by a recursive optimization of multiple objectives. These objectives can include accuracy and quality. The quality objective can include the objective of drilling a smooth borehole by minimizing strain energy and torsion. The accuracy objective can include the objective of minimizing the deviation of the borehole trajectory during the real-time drilling process from a predefined well-plan. The trajectory control problem, therefore, can be a multi-objective problem where, in some embodiments, the weightings of the individual objectives can be adjusted along the process.

  • Publication number: 20150317585
    Abstract: Methods and systems for generating a well-plan with respect to geological targets. The well plan can be optimized for strain energy and torsion, to generate a smooth borehole. The resultant path can be constrained for curvature which is a design parameter and can produces a path feasible for a directional steering tool to achieve. The method can be constructed as a convex optimization problem, and/or provide a unique solution by interior point methods.
