Vancouver, British Columbia--(Newsfile Corp. - October 28, 2026) - Dune Oil Corp. (formerly Trillion Energy International Inc.) (CSE: DUNE) (OTCQB: DUNXF) (FSE: Z621) ("Dune" or the "Company") is pleased to announce the appointment of Allan Albertson, P.Eng., and Dean Casorso, MBA, CET, as technical advisors to support the planning and evaluation of potential well re-entry, completion and production operations on the Company's M47 oil exploration block in southeastern Türkiye.

The appointments bring together international experience in petroleum engineering, drilling, well completions, reservoir evaluation and oilfield operations, with particular relevance to the fractured carbonate reservoirs encountered on the M47 Block.

Advancing the C-1 and C-2 Well Programs

The initial focus of the advisory team will be the technical evaluation and planning of potential re-entry and completion programs for the Çetinkaya-1 ("C-1") and Çetinkaya-2 ("C-2") wells, together with strategies to evaluate reservoir deliverability, water management strategies and potential commercial production.

The C-1 well, drilled in 2025, encountered light crude oil with gravity of 32.4° API. Previous drilling operations encountered significant lost circulation, highlighting the technical challenges associated with drilling and completing naturally fractured carbonate formations.

The advisors will assist Dune in assessing well conditions, reviewing available drilling and geological information, evaluating appropriate drilling and completion methods, and developing recommendations intended to preserve reservoir productivity while managing operational risks and costs.

Initial technical priorities are expected to include:

• Well re-entry planning: Reviewing the C-1 and C-2 wellbores and assessing potential re-entry, deepening and completion options.
• Reservoir protection: Evaluating drilling-fluid, lost-circulation and completion strategies suitable for naturally fractured carbonate formations, with emphasis on limiting formation damage.
• Production evaluation: Assessing well-testing, stimulation and production strategies to better characterize reservoir performance and potential commercial deliverability.
• Operational planning: Supporting development of practical well programs, contractor evaluations, operating procedures and preliminary cost estimates.
• The advisors' recommendations will support the Company's evaluation of potential well operations and future development planning in coordination with its local operating partners.
