Abstract: A method to design well trajectories includes determining dogleg severity as a function of inclination, and a corresponding rate of penetration performance of the tool by a hybrid model including physical modelling and machine learning correction. The method includes solving for optimal steering parameters to predict a dogleg severity as close as possible to a desired dogleg severity at a given inclination of the trajectory, which is repeated for dogleg severity and inclination combinations of interest. The rate of penetration for feasible points is also determined and a rate of penetration (or time-to-target) map can be produced. Potential trajectories are then evaluated relative to the map to estimate drilling time-to-target, and an optimal trajectory can be selected that has a lowest time-to-target while also being feasible for the tool and optionally avoiding risks or downhole obstacles.

Abstract: In a method of video decoding performed in a video decoder, coded information of a current block and neighboring blocks of the current block is received from a coded video bitstream. A most probable mode (MPM) list is generated for the current block. The MPM list includes intra modes that are determined based on intra modes of the neighboring blocks of the current block. One of gradient values and cost values of the neighboring blocks are calculated based on the intra modes of the MPM list. The intra modes of the MPM list are sorted based on the one of the gradient values and the cost values of the neighboring blocks, where each of the intra modes in the MPM list is associated with a respective one of the gradient value and the cost value. Further, the current block is reconstructed based on the MPM list.
