Abstract
A method and apparatus for oil and gas operations according to which a bottom hole trajectory of a drilling well is surveyed using a survey tool located uphole from a drill bit positioned at a bottom hole location. One or more offset wells are identified having a trajectory, or respective trajectories, closing on the bottom hole trajectory of the drilling well. An anti-collision steering strategy for the drilling well to avoid the one or more offset wells is determined.
