The Direct XCD bit reached target depth within 7 hours of drilling time.
The Direct XCD bit reached target depth within 7 hours of drilling time, which is 1.5 hours less than the planned drilling time and 53% less than the drilling time required on a nearby offset. This represents an average ROP of 132.8 ft/h.

Background
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.
