Australian energy stocks, specifically the sub-index, are experiencing a rise as much as 2.5 percent, possibly marking their best day since June 16, if the gains maintain.

The sub-index has reached its highest level since September 20.

This rise in energy stocks may be attributed to the increase in oil prices, which have been lifted due to a steep drop in U.S.

crude stocks, which in turn is causing global supply worries.

Major contributors to the sub-index are Woodside Energy (ASX:WDS) and Santos (ASX:STO), showing gains as much as 3.0 percent and 2.7 percent, respectively.

Woodside shares have the potential to mark their best day since July 12 if the current trend persists.

Concurrently, Santos is witnessing its biggest intraday percentage jump since June 16.

As of the last close, energy stocks have been up 3.6 percent this year.

Woodside Energy (ASX:WDS) is a major player in the Australian energy sector, focusing on the exploration, development and production of petroleum.
