Refiner and marketer Caltex Australia has started the extended maintenance at its 109,000 b/d Lytton refinery in Brisbane, Queensland.
Maintenance at Lytton was originally planned to start in July. The work is likely to continue until mid-August as with the original plan, effectively more than doubling the length of the turnaround. But Caltex has not provided an actual restart deadline, with it dependent on market conditions.
Global fuel demand erosion caused by the inmpact of Covid-19 is expected to affect refining conditions for at least several months, said Caltex Australia interim chief executive Matt Halliday.
The demand and broader impacts of Covid-19 on its business have become more acute into the April-June quarter, Halliday said. "In the current environment we are seeing a weakened crude oil market, with increase in storage on water lifting crude and product freight rates."
Australian jet fuel demand is expected to be down 80-90pc during the period that travel restrictions remain in place, Halliday said. Preliminary data released this week showed passenger volumes almost 99pc below levels a year earlier.
Retail fuel sales volumes are down by 16pc for the year to April compared with the same period in 2019, he said. Caltex accounts for around a third of all retail fuel sales volumes in Australia.
Caltex reported a slight rise in refinery margins at Lytton, which is the firm's only refinery, to $4.83/bl in April, up from $4.62/bl in March and down from $10.96/bl in March 2019.
Sales from Lytton's production fell to 95,000 b/d in April from 104,000 b/d in March and down from 92,000 b/d in April 2019. The reduced production was a result of decisions to reduce the economic impact of the coronavirus because of weaker margins, Caltex said.
The average Caltex refinery margin was $4.86/bl during January-April, down from $8.32/bl in the same period in 2019. Sales from Lytton's production rose to 106,000 b/d during January-April compared with 101,000 b/d a year earlier.
