overflow image
Using a jetting BHA, the operator successfully initiated the A-15 sidetrack and kickoff from the cement plug with a 1.83° bent jetting BHA, which safely eliminated tracking A-16 casing and positioned the well to the right azimuth. The 1.5° bent motor executed an average of –26°/100-ft turn rate with good directional control. In addition to saving the slot, the operator ran the casing to bottom and successfully cemented the casing.
