13-20 最新消息
公司很高兴地宣布，Blythe 13-20 井的钻探总深度为 5,300 英尺 mDKB（1,615 米），按时、按预算完成，且未发生任何 HSE 事故。该井钻穿了大约 3,028 英尺（923 米）的沉积岩和 2,272 英尺（692 米）的前寒武纪基底。Blythe 13-20 井钻入了公司土地上的一个新地质远景区。 Blythe 13-20井场位于1982年钻探的历史悠久的Scott-1井以东约1,400米处，该井报告沉积层段的氢浓度高达56%。钻井深度比Scott-1井深3,100英尺（945米）。该公司在井场附近拥有6,860净英亩的土地。

斯伦贝谢 (SLB) 实施了一项广泛的地层评估计划。该计划包括在钻井过程中实时记录泥浆气体测井数据、在地面采集泥浆气体样品、进行广泛的电缆测井以及岩屑采集。从 Sue Duroche 3 项目中汲取的经验教训以及详细的预先规划，最终确保了数据采集计划的成功。

钻井时，实时泥浆气体测井在不同时间间隔记录了氢气和氦气读数，表明该地区存在氢气和氦气2 。地面收集的泥浆气体样品现在正送往独立实验室（Isotech Laboratories Inc.）进行验证和量化，届时将向市场发布结果。

运营展望
根据对 Sue Duroche 3 的初步观察，公司已决定将第三口井 McCoy 1 添加到该钻井计划中。独立实验室分析证实，Sue Duroche 3 泥浆气体样品2 中的氢气浓度高达 96%，氦气浓度高达 5%。早在 5 月份，该井就立即转换为评价井。该井距离 McCoy 1 现场位置 9 公里。Murfin

116 钻井平台将准备在 6 月份调动到 McCoy 1。现场工作人员现在将短暂休息，以避免人员更换，并作为最佳实践保持整个勘探井活动的连续性。 McCoy 1 预计将于 2025 年 6 月底开钻。

根据对Sue Duroche 3井和Blythe 13-20井的初步观察，公司将在未来几周内开始规划Blythe 13-20井的重新入井作业，并将其改造为评估井。本公告已获董事会授权发布。

• Blythe 13-20 well was completed on time, on budget, with no HSE incidents. The wireline logging operations were completed over the weekend. The total depth of the well is almost two and half times deeper than the nearby historic Scott-1 (1982) which reported hydrogen concentrations of up to 56%1 in the sedimentary section.
• The well was targeting a new geological play for both hydrogen and helium within HyTerra’s 100% owned and operated Nemaha Project acreage.
• Mud gas log readings at various depths in Blythe 13-20 indicate the presence of a hydrogen and helium play in this area2 . Mud gas samples from surface are being sent to IsoTech Laboratories Inc. for independent verification and compositional analysis.
• Blythe 13-20 will now be converted to an appraisal well in coming weeks based on initial observations from both Sue Duroche 3 and Blythe 13-20.
• The Company has also decided to add a third well, McCoy 1, to this drilling programme based on the initial observations from the first well, Sue Duroche 3, located 9 km to the west. This well was converted immediately into an appraisal back in May.
• Murfin 116 drilling rig will mobilise to the McCoy 1 well site following a scheduled crew break.

HyTerra Limited (HyTerra or the Company) has increased the firm wells in the drilling sequence to a total of three wells to be drilled between April and July 2025 at the Nemaha Project in Kansas, USA. These wells are the first steps for the Company in executing a comprehensive 12-month exploration work program designed to unlock the potential of natural (white) hydrogen in Kansas through its 100% owned and operating subsidiary HYT Operating LLC. This exploration program funding is sourced from an investment in the Company by Fortescue Future Industries Technologies Pty Ltd.

Blythe 13-20 Update
The Company is pleased to announce that Blythe 13-20 was drilled to a total depth of 5,300ft mDKB (1,615m) on time, on budget, with no HSE incidents. The well drilled through approximately 3,028ft (923m) of sedimentary rocks and 2,272ft (692m) of Pre-Cambrian basement. Blythe 13-20 well was drilled into a new geological play in the Company’s acreage. The Blythe 13-20 well site is located around 1,400m east of the historic Scott-1 well drilled in 1982, which reported hydrogen concentrations of up to 56% in the sedimentary section1 . The drilling depth reached was 3,100 ft (945m) mDKB deeper than Scott-1 well. The Company has 6,860 net acres in close vicinity to the well site.

An extensive formation evaluation program was executed by Schlumberger (SLB). This program entailed recording mud gas log data in real time during drilling, mud gas samples collected at surface, extensive wireline logging, and cuttings. The learnings from Sue Duroche 3 and detailed pre-planning resulted in a successful data acquisition program.

The real time mud gas log recorded hydrogen and helium gas readings at different intervals when drilling, indicating the presence of a hydrogen and helium play in this area2 . The mud gas samples collected at surface are now being sent to an independent laboratory (Isotech Laboratories Inc.) for verification and quantification at which time the results will be released to the market.

Operations Lookahead
The Company has decided to add a third well McCoy 1 to this drilling programme based on the initial observations from Sue Duroche 3. Independent laboratory analyses verified concentrations of up to 96% hydrogen and 5% helium from Sue Duroche 3 mud gas samples2 . The well was converted immediately into an appraisal well back in May. The well is located 9km from the McCoy 1 site location.

The Murfin 116 drilling rig will then be prepared to mobilise to McCoy 1 in June. The field crew will now take a short break to avoid crew change out and maintain continuity across the entire exploration well campaign as best practice. McCoy 1 is expected to spud by end-June 2025.

Based on initial observations from both Sue Duroche 3 and Blythe 13-20, the Company will start planning a re-entry of the Blythe 13-20 to convert it to an appraisal well in coming weeks. This announcement has been authorised for release by the Board of Directors.
