Abstract:
1. A computer implemented method for positioning a pad, comprising: computing a slot template geometry for the pad based on a predetermined number and position of slots on the pad using a computer processor; computing nudge parameters for each plan assigned to a respective slot based on the slot template geometry using the computer processor; adjusting a nudge for each plan based on the nudge parameters for each respective plan; moving each nudge by a predetermined angle toward a target azimuth if a difference between an azimuth from each nudge to a respective slot and another azimuth from each nudge to a respective target does not meet a predetermined allowable value; repeating the steps of adjusting a nudge for each plan and moving each nudge until each plan is in a position that meets a minimum separation distance at a final kick-off depth and the difference between the azimuth and the another azimuth for each respective nudge meets the predetermined allowable value; and applying the nudge for each respective plan.
