Pantheon Resources宣布，在阿拉斯加北坡靠近管道和运输基础设施的Kodiak和Ahpun油田成功钻探了Dubhe-1评估井水平段。该水平段成功落入顶层位(SMD-B)，这是Dubhe-1导孔确认的主要目标层位。

Dubhe-1井项目的第二阶段包括封堵导向孔，并在主要的SMD-B储层钻探侧钻井，进入导向孔东北约550英尺的目标层位。该井由Nabors 105AC钻机钻探，总测量深度达15,800英尺，其中约5,200英尺位于SMD-B储层内，超出钻探前的预期。

生产测试水平段计划长度为 3,000 至 4,000 英尺，根据先导孔结果优化轨迹，结合良好的钻井性能，实现了这一良好结果。

在侧钻过程中再次发现了额外的浅层含油气层。所有层段均采用全套随钻测井 (LWD) 工具和挥发物分析服务 (VAS) 对密封和未密封岩屑样品进行记录。

Pantheon Resources announced the successful drilling of the Dubhe-1 appraisal well lateral at the Kodiak and Ahpun oil fields near pipeline and transportation infrastructure on Alaska’s North Slope. The lateral was successfully landed in the topset horizon (SMD-B), the primary target confirmed in the Dubhe-1 pilot hole.

The second phase of the Dubhe-1 well program consisted of plugging back the pilot hole and drilling the lateral sidetrack into the primary SMD-B zone, entering the target horizon approximately 550 ft northeast of the pilot hole. The well, drilled by the Nabors 105AC rig, achieved a total measured depth of 15,800 ft with approximately 5,200 ft within the SMD-B reservoir, exceeding pre-drill expectations.

The production test lateral was planned for 3,000—4,000 ft and optimization of the trajectory based on the pilot hole results, combined with good drilling performance, achieved this upside outcome.

The additional shallow hydrocarbon bearing zones were encountered again in the sidetrack. All intervals were logged with a full suite of Logging While Drilling (LWD) tools and Volatiles Analysis Service (VAS) of both sealed and unsealed cuttings samples.
