Discoverer Clear Leader Breaks World Record with Technical Partnership


During its drilling campaign in the U.S. Gulf of Mexico, the Discoverer Clear Leader worked with partners Chevron U.S.A. Inc. and Schlumberger to break a new world record. On the Jack PS005 well, the DCL team set the new world record for the longest perforating interval at measured depth and pressure.

Perforating is a stage of the completion process where explosive charges are fired at depth to create holes through the casing. Perforating connects the well to the reservoir, allowing oil and gas fluids to flow through the holes and up the well. The 1,350-foot gross interval broke the previous record set on the St. Malo PS003 well, which was a 1,288-foot gross interval.

The DCL team’s achievement was supported and congratulated by Chevron, recognizing the DCL team and Schlumberger TCP crew for a job well done. The team stayed focused on the tasks at hand after a long period of other equipment downtime. This is a milestone to be proud of!
