Highlights

Geelong refines crude oil into transport fuels and other petroleum products.
Refinery operations combine separation and conversion of crude-derived streams.
A fire in the gasoline complex disrupted production in April 2026.
The residue catalytic cracking unit restarted in June 2026.
H1 2026 Geelong Refining Margin averaged US$21.1/bbl.

Viva Energy Group Limited (ASX:VEA) operates fuel, convenience retail and energy infrastructure businesses across Australia, including the Geelong Refinery in Victoria. The refinery processes crude oil into products serving transport and commercial customers. Its 2026 operations illustrate how refinery distillation and downstream conversion units work together, and how an April incident affected output before key processing equipment returned to service.

From Crude Oil to Different Fuel Streams

Refining starts by preparing crude oil and separating it into fractions based on boiling characteristics. Atmospheric distillation is the principal first separation stage; lighter components are recovered apart from heavier streams. Additional processing can convert or treat these streams to make finished products with the required specifications.

At Geelong, Viva Energy Group Limited (ASX:VEA) manufactures petrol, diesel and aviation fuels, alongside specialty products.

Catalytic Cracking and Product Yields

Catalytic cracking converts heavier refinery streams into more valuable lighter products, including components used in transport fuels. Viva Energy Group Limited (ASX:VEA) identifies its Residue Catalytic Cracking Unit (RCCU) as a key Geelong processing unit. Its June 2026 announcement explained that restarting the RCCU and associated equipment would improve finished-product yields by converting a greater share of lower-value intermediate streams.

The refinery also has an Alkylation unit associated with its gasoline complex. That unit converts certain refinery by-products into gasoline components. The company said in June that the damaged unit had been isolated and would remain offline, while repair or replacement options were examined. It expected the refinery to operate without the unit throughout 2027, based on its assessment at the time.

April Fire and June Restart

A fire occurred in the Geelong gasoline complex on 15 April 2026. Viva Energy Group Limited (ASX:VEA) reported that personnel were accounted for and there were no injuries. On 20 April, it expected reduced production of diesel and jet fuel at approximately 80% of capacity and petrol at approximately 60%, while inspection and restoration works continued.

On 23 June 2026, the company announced completion of restart works for the RCCU. With the unit and associated facilities returning to service, it expected production to exceed 90% of normal capacity.

First-Half Refining Performance

In H1 2026, Viva Energy Group Limited (ASX:VEA) recorded a Geelong Refining Margin of US$21.1/bbl on crude intake of 19.7MMbbl. The group reported Energy & Infrastructure replacement-cost EBITDA of $353.7M. Regional refining margins were elevated, more than offsetting the effect of the April incident on segment earnings, according to its half-year reporting.

Geelong’s April and May 2026 refining margin was US$23.9/bbl from 6.5MMbbl of intake. The company linked this performance to reduced output and lower-margin yields after the fire, alongside changes in crude premia.

Operating Safety and Environmental Oversight

Refinery processing involves flammable hydrocarbons, high-temperature equipment and emissions management. In September 2026, Victoria’s environmental regulator granted a temporary exemption relating to summer petrol specifications because equipment damaged in April remained unavailable. It assessed the exemption as posing low risk of harm and reiterated the refinery’s continuing environmental obligations.

For Viva Energy Group Limited (ASX:VEA), ongoing operational reporting can clarify production rates, unit availability, repairs, refining margins and compliance outcomes.

Key Insights

Geelong’s 2026 experience demonstrates the dependence of finished-fuel production on both initial separation and downstream conversion capacity. Viva Energy Group Limited (ASX:VEA) restored its RCCU after the April fire, while the Alkylation unit remained unavailable. Reported H1 2026 margins and intake provide financial and operating context without implying that all equipment had returned to normal.
