Key Highlights

Santos is a major Australian Natural Gas and LNG producer, with operations spanning Australia and Papua New Guinea and a portfolio supported by projects including Barossa and Pikka.
Q2 2026 delivered stronger operating performance, with production increasing 3% to 23.1 million barrels of oil equivalent and sales Revenue rising 6% to $1.349 billion.
Barossa is approaching planned production levels, operating at approximately 97% of planned rates in the latest quarterly update, while Pikka Phase 1 continues progressing toward plateau production.
Technically, STO has broken above the $8.09 neckline of an Inverse Head & Shoulders pattern following its recovery from the June 2026 low, confirming the bullish Reversal setup.
The decisive breakout above $8.09 strengthens the medium-term bullish outlook and points toward a measured-move target near $9.23, based on the pattern shown on the chart.
The former $8.09 resistance level is now an important near-term support level for the stock following the breakout.

Following a period of consolidation, Santos Limited (ASX: STO) has moved through an important technical inflection point. The Daily Chart shows STO closing at $8.31, breaking above the $8.09 neckline and the descending Trendline that previously capped the recovery. The breakout confirms the potential Inverse Head & Shoulders structure that developed after the stock declined toward approximately $7.00 in June 2026. A sustained move above the breakout zone could signal the beginning of a new medium-term recovery phase.

The LNG and Gas Growth Story

Santos is one of Australia's major oil and gas producers, with its Investment case increasingly supported by LNG and gas production from major projects. The company's latest operating update showed improving production and revenue momentum.

Higher Production: Santos produced 23.1 million barrels of oil equivalent in Q2 2026, representing a 3% increase from the previous quarter.
Improving Revenue: Sales revenue increased 6% quarter-on-quarter to $1.349 billion, reflecting stronger operating performance.
Barossa Progress: The Barossa project was reported to be producing at approximately 97% of planned rates, an important milestone as the project moves toward steady-state production.
Pikka Development: Pikka Phase 1 continues to progress toward plateau production, providing another potential source of production growth.
Strong Cash Generation: Santos reported approximately $378 million of free Cash Flow from operations for the first half of 2026.
Gas Sales Agreement: The company also executed a 10-year gas sales agreement with the South Australian Government, supporting the longer-term outlook for its domestic gas business.

Associated Risks

While the technical structure has improved, several risks remain.

The Inverse Head & Shoulders breakout needs to hold above the $8.09 neckline to maintain the bullish scenario. Failure to sustain the breakout could result in another period of consolidation or a pullback toward the right-shoulder area around $7.40–$7.60, with the June low near $7.00 providing a more important support reference.

Santos also remains exposed to movements in global oil and LNG prices. Commodity-price Volatility can materially affect realised prices, revenue and cash flow. Recent market volatility reinforces the sensitivity of energy stocks to changing supply, Demand and geopolitical conditions.

Project execution also remains important. Santos is continuing to ramp up major projects, and delays, commissioning issues or weaker-than-expected production could affect the anticipated improvement in operating performance.

Technical Outlook

STO's daily chart has moved through an important technical inflection point, with the share price breaking above the $8.09 neckline of the Inverse Head & Shoulders pattern.

STO's Daily Price Chart (at the closing price of 19/08/2026). Powered by: tradingview.com.

STO has developed an Inverse Head & Shoulders pattern following the decline from its earlier 2026 highs. The recent breakout suggests that bearish momentum has weakened and buyers have regained control.
The neckline was positioned around $8.09. STO has now closed above $8.09 at $8.31, confirming the bullish technical breakout. The move above the descending trendline provides additional confirmation of the reversal.
The measured-move projection shown on the chart points toward approximately $9.23. This represents potential upside of around 11.1% from the latest closing price of $8.31.
The former $8.09 neckline is now an important near-term support level. Failure to hold this level could trigger further consolidation toward the $7.40–$7.50 right-shoulder region, followed by the broader $7.00 region.

Bottom Line

Santos' improving production profile and progress across its major LNG and oil projects provide a supportive fundamental backdrop, with Barossa approaching planned production levels and Pikka Phase 1 continuing to progress toward plateau production.

Technically, STO has broken above the key $8.09 neckline of the Inverse Head & Shoulders pattern and closed at $8.31. A sustained breakout above this level strengthens the bullish reversal and places the $9.23 measured-move target in focus, while a move back below $8.09 would weaken the breakout and could lead to consolidation toward the $7.40–$7.50 support area.
