The discovery, made at the Charlemont-1 exploration well in the Otway Basin, reinforces the company’s position in the region’s growing gas market. This exploration success follows an earlier find, adding strength to the commercial case for further exploration in the area.
Charlemont-1 Well: A Key Gas Discovery Offshore Victoria
The Charlemont-1 well, situated about 55 kilometers off the coast of Victoria, encountered gas in the Waarre C sandstone. The gas discovery was confirmed after the successful recovery of a representative sample. The discovery is notable because it was not initially anticipated, providing an upside potential for future exploration. The gas sample’s composition revealed a carbon dioxide concentration of approximately 16 mol%, which is comparable to nearby gas fields like La Bella.
Elevated gas readings and resistivity responses were recorded in the Waarre A sandstone. These indicators suggest the probable presence of hydrocarbons, although further analysis will be required to confirm their commercial viability. The discovery’s location near existing infrastructure enhances its commercial prospects, as it will allow for easier development and integration into Australia’s gas supply chain.
The Charlemont discovery is a part of ConocoPhillips’ ongoing Otway Exploration Drilling Program, which aims to tap into the region’s untapped resources. The program focuses on identifying gas reserves close to existing offshore production facilities. This strategy allows for efficient and cost-effective exploration, reducing the time needed to bring new gas resources to market.
Impact on Australia’s Gas Market and Next Steps
This discovery significantly strengthens the case for increased gas production from the Otway Basin. With Australia’s east coast gas market tightening, new supplies such as Charlemont-1 will help address growing demand. According to Noel Newell, executive chairman of 3D Energi, the discovery enhances development options, subject to further technical and commercial evaluation.
The Charlemont-1 well is part of an effort to assess the Charlemont Trend, a gas-rich chain extending towards the La Bella discovery. This trend now shows gas charge at both ends, de-risking several nearby prospects with consistent seismic anomalies. The results validate the effectiveness of ConocoPhillips’ infrastructure-led exploration approach.
Looking ahead, no decision has been made regarding further drilling. ConocoPhillips holds a 51% operating interest in the permit, with partners Korea National Oil Corporation and 3D Energi holding the remaining stakes. The future of the Charlemont discovery will depend on additional technical assessments and the evolving gas market conditions in Australia.
