Highlights

  • Winchester Energy has drilled the JVU-4 water-injection well at the Varn oil field in Texas.
  • The well forms part of a planned 10-well waterflood development.
  • The program follows completion of the JVU-5 producing well in October 2025.
  • Future production gains will depend on injection performance and continued project execution.

Winchester Energy Limited (ASX:WEL) continues progressing its secondary recovery strategy at the Varn oil field in Texas after drilling a new water-injection well designed to support oil production from the mature reservoir. The latest operational milestone extends the company's staged waterflood development following the addition of a new producing well in late 2025. While the initiative is intended to improve reservoir performance over time, its commercial impact will depend on operational results and the company's ability to continue funding the broader development program.

Waterflood Development Moves Forward

Winchester commenced drilling the JVU-4 water-injection well at its Jocelyn-Varn Joint Venture in Taylor County, Texas.

The well targets a planned depth of approximately 4,900 feet and is intended to become part of a broader 10-well producer-injector configuration designed to maintain reservoir pressure and improve oil recovery.

Once completed, JVU-4 is expected to be connected to the existing water supply system before injection operations begin.

The company has described the project as another step in optimising production from the mature Varn oil field.

Program Builds on Earlier Production Well

The injection well follows completion of the JVU-5 producing well, which entered production during October 2025.

According to the company, JVU-5 initially produced approximately 14 barrels of oil and 48 barrels of water per day.

Together, the producing and injection wells form part of Winchester's longer-term strategy to improve recovery from existing oil reservoirs rather than relying solely on new field acquisitions.

The effectiveness of the waterflood program will become clearer through future production data released by the company.

Texas Assets Anchor Operations

Winchester Energy focuses on conventional oil and gas production across Taylor County and Nolan County in West Texas.

In addition to the Varn project, the company operates approximately 20 wells in Nolan County, where periodic workovers are undertaken to maintain production.

For the year ended 31 December 2025, Winchester reported revenue of USD 1.44 million, a net loss of USD 1.50 million, and cash of USD 466,104. The company also reported a working capital deficit of USD 482,857, highlighting its continued reliance on disciplined capital management.

Funding and Execution Remain Key

Alongside operational activities, Winchester has undertaken several capital management initiatives during 2026, including applying to quote new shares and issuing broker options following shareholder approvals obtained at its annual general meeting.

As a micro-cap oil producer, future progress is expected to depend on successful execution of the Varn waterflood, stable oil prices and continued access to funding.

Upcoming quarterly reports are expected to provide updates on injection performance, production levels and operational progress across the Texas portfolio.

What Investors May Watch

Investors may monitor completion of the JVU-4 well, production updates from the Varn waterflood, quarterly operating results, funding initiatives and future ASX announcements.

Risks

Winchester Energy remains exposed to oil price volatility, operational execution risk, funding requirements, working capital constraints, shareholder dilution, production uncertainty and the possibility that the waterflood program may not deliver the expected improvement in oil recovery.
