Abstract
A method of preventing a collision of a subject wellbore in a downhole environment includes receiving offset wellbore data corresponding with one or more offset wellbores and identifying, based on the offset wellbore data, one or more no-go zones for each of the one or more offset wellbores. The method further includes determining a plurality of safe points corresponding with a potential intersection of the subject wellbore with the one or more no-go zones and, defining an escape zone within the plurality of safe points. The method further includes determining a trajectory for the subject wellbore within the escape zone.
