Oil and Gas, Property and Equipment [Text Block]	5. OIL AND NATURAL GAS PRODUCING ACTIVITIES Unevaluated Properties As of December 31, 2025 and 2024, the Company had no unevaluated oil and natural gas properties. Ceiling Test and Impairment For the year ended December 31, 2025 and 2024, the Company recorded $3.6 million and $11.9 million, respectively, of ceiling test write-downs of its oil and natural gas properties. The impairment resulted from declines in commodity prices used in the ceiling test calculation and reduced the carrying value of oil and natural gas properties. The reserves used in the ceiling test incorporate assumptions regarding pricing and discount rates over which management has no influence in the determination of present value. In the calculation of the ceiling test as of December 31, 2025, the Company used $65.34 per barrel for oil and $3.39 per one million British Thermal Units (MMbtu) for natural gas (as further adjusted for property, specific gravity, quality, local markets and distance from markets) to compute the future cash flows of the Company’s producing properties. In the calculation of the ceiling test as of December 31, 2024, the Company used $75.48 per barrel for oil and $2.13 per one million British Thermal Units (MMbtu) for natural gas (as further adjusted for property, specific gravity, quality, local markets and distance from markets) to compute the future cash flows of the Company’s producing properties. The discount factor used for both years was 10%.
