Patent number: 9297205Abstract: A method includes receiving toolface information corresponding to a location of the bottom hole assembly (BHA) with respect to a target drilling path and drift information. The surface steerable system calculates a first toolface vector from a first location of the BHA to the target drilling path to create a convergence path to the target drilling path and calculates an adjustment of the first toolface vector to a second toolface vector to account for system drift defined by the drift information such that the BHA will converge with the target drilling path by drilling in accordance with the second toolface vector. The surface steerable system modifies at least one drilling parameter to alter a drilling direction of the BHA based on the calculated second toolface vector and transmits the at least one drilling parameter to the drilling rig to target the BHA in accordance with the second toolface vector.Type: GrantFiled: April 2, 2015Date of Patent: March 29, 2016Assignees: Hunt Advanced Drilling Technologies, LLC, Board of Regents, The University of Texas SystemInventors: Todd W. Benson, Teddy Chen, Sashmit Bhaduri

Publication number: 20160032705Abstract: A system and method for surface steerable drilling are provided. In one example, the system receives feedback information from a drilling rig and calculates an estimated position of a drill bit in a formation based on the feedback information. The system compares the estimated position to a desired position along a planned path of a borehole. The system calculates multiple solutions if the comparison indicates that the estimated position is outside a defined margin of error relative to the desired position. Each solution defines a path from the estimated position to the planned path. The system calculates a cost of each solution and selects one of the solutions based at least partly on the cost. The system produces control information representing the selected solution and outputs the control information for the drilling rig.Type: ApplicationFiled: October 13, 2015Publication date: February 4, 2016Inventors: TODD W. BENSON, TEDDY CHEN

Publication number: 20150193705Abstract: Provided are a system and method for calculating and selecting a convergence path based on cost. In one example, the method includes identifying multiple geometric convergence paths that each provides a convergence solution from a defined bottom hole assembly (BHA) location to a target path. A total monetary cost is calculated for each of the geometric convergence paths using an offset cost based on a distance of the geometric convergence path from the target path, a curvature cost based on an amount of curvature of the geometric convergence path, and a time cost based on an estimated amount of time needed to drill the geometric convergence path. The total monetary costs of the geometric convergence paths are compared and one of the geometric convergence paths is selected based on the total monetary cost of that geometric convergence path relative to the total monetary costs of the other geometric convergence paths.Type: ApplicationFiled: March 17, 2015Publication date: July 9, 2015Inventors: TODD BENSON, JOHN BURKHART, TEDDY CHEN
