PX ENERGY COMPLETES EMERGENCY MAINTENANCE ON SCHEDULE

Questerre Energy Corp. has noted the emergency turnaround at the PX Energy oil shale processing facility in southern Brazil was completed last week. The plant has been on-line since late Aug. 18, 2026.

The turnaround was completed on budget and on schedule with zero recordable safety incidents. The maintenance was to repair a critical pipe failure in the furnace that supplies heat to the main processing facility, also known as the retort. The company also completed additional maintenance work on the retort to restore operating efficiency. For the past six days, the retort has been operating at over 90-per-cent efficiency. The company was able to maintain continuous operation of the atmospheric distillation unit during the turnaround. It anticipates meeting its minimum sales commitments under long-term contracts for the month of August despite the unexpected turnaround.

Michael Binnion, president and chief executive officer of Questerre, commented: "We are pleased the team completed this unscheduled turnaround according to plan. We are looking forward to applying the learnings to mitigate the root cause of this shutdown and to optimize our scheduled turnaround next spring."
