Tech Report: Direct XCD Bit Helps Parex Resources Reduce Drill Time by 17.6% Below Plan and 53% Below Nearby Offset

Drillable alloy casing bit achieves effective ROP of 301.8 ft/h in Colombian well

Direct XCD Bit Helps Parex Resources Reduce Drill Time by 17.6% Below Plan and 53% Below Nearby Offset

Publication Date: 10/13/2017

Parex Resources wanted to improve ROP while drilling a 12 1/4-in shallow section for a 9 5/8-in casing. Using the i-DRILL integrated dynamic system analysis service, a drill map was developed for the section depth from 60–726 ft [18.29–221.29 m]. While the drill time of the nearest offset was 15 hours, the plan using a Direct XCD drillable alloy casing bit predicted 8 1/2 hours of drill time.
