Latest Patents

One of his notable patents is titled "Nonlinear model predictive control for directional drilling applications." This invention utilizes a nonlinear Delay Differential Equation (DDE) model to predict borehole drilling according to a well plan. To tackle the challenges of real-time control in drilling, Tian employs techniques such as generalized feedback linearization and finite element concepts. This approach transforms the nonlinear DDE model into a linear Ordinary Differential Equation (ODE) form, allowing for the optimization of control inputs. The effectiveness of this model has been validated through closed-loop simulations, demonstrating its capability to maintain drill string alignment with planned trajectories amidst disturbances.

Another significant patent is focused on "Systems and methods to determine the steering of a bit." This method involves analyzing a bottomhole assembly model, which includes a housing and a shaft. By estimating forces and moments at the contact point between the shaft and housing, Tian's method determines deflections and provides outputs indicative of bit steering. This innovation is crucial for improving the accuracy of directional drilling.
