Abstract: Methods, drilling systems, and computer-readable media for evaluating candidate correctional trajectories for a directional drilling well. If the user wishes to investigate alternatives trajectories or trajectories to get a BHA back to a planned trajectory, the computing system allows the user to enter one or more intermediate targets. The computing system generates drilling parameters for the alternative targets and displays them to the user. The user can adjust parameters and intermediate targets, as well as drilling parameters, to investigate a range of possible solutions before selecting an update to the planned trajectory.

Abstract: An electromagnetic valve includes an extra-high pressure injection system control valve having soft metal powder particles in a magnetic stator core. Electroless nickel plating is applied to the stator core to provide an intermediate surface to absorb grinding wheel stress as a working face is exposed during manufacturing, as well as an external compression layer or casing to hold or encapsulate the powder particles in place and together during assembly and use.
