该项目位于Kepala Burung生产分成合同（PSC）范围内，具体位于Arar区块，距离公司现有的Arar生产集群以东约23公里。该井正在陆上钻探，钻井区域勘探程度相对较低，钻井作业将使用集团自有钻机。Karim-1井的计划钻井轨迹为垂直井，总深度约为4300英尺（1311米）。RH Petrogas表示，钻井和完井作业预计将持续40多天。

Karim-1 井的主要目标是评估中新世 Kais 油藏的石油潜力，该油藏位于早期 Klaifi-1 油田发现地层上倾的构造封闭区域内。

Klaifi-1 油田位于 Karim-1 油井位置西北约 7 公里处。

RH Petrogas公司表示，中新世Kais组是一套碳酸盐岩地层，形成了一个浅海台地，其中分布着“局部礁体复合体”。它被认为是Kepala Burung PSC区块的主要产油储层。

Karim-1井钻探工作完成后，钻机将调往西北Klagagi-1勘探井进行钻探。

该井位于 Arar 生产集群东北方向约 15 公里处，距离 Karim-1 井区约 12 公里。

RH Petrogas 集团首席执行官兼执行董事 Francis Chang 表示：“我们很高兴开始在 Kepala Burung PSC 钻探我们的两口背靠背勘探井。”

“自 2024 年以来，修复工作一直在进行中，包括获得必要的环境和林业许可证、采购和场地准备，以及升级钻井平台以提高其能力和可靠性。”

张补充道：“这两口井位于阿拉尔区块东部偏远但前景广阔的区域，连续钻探将显著降低钻机调动和辅助物流成本。”

RH Petrogas 是一家总部位于新加坡的独立上游油气公司，从事资源开发和生产，重点关注东南亚国家联盟地区。

The project is located within the Kepala Burung production sharing contract (PSC), specifically in the Arar block, approximately 23 km east of the company’s existing Arar production cluster. The well is being drilled onshore in a “relatively under-explored area” using the group’s own rig. The planned trajectory for Karim-1 is a vertical well with a total depth of around 4300 ft (1311 m). RH Petrogas said that drilling and completion activities are expected to take more than 40 days.

The main objective of the Karim-1 well is to evaluate the oil potential of the Miocene Kais reservoir, which is located within a structural closure up-dip of the earlier Klaifi-1 oil discovery.

The Klaifi-1 oil discovery is located approximately 7 km north-west of the Karim-1 well location.

RH Petrogas said that the Miocene Kais formation is a carbonate sequence that forms a shallow marine platform with “localised reefal complexes”. It is recognised as the main producing reservoir in the Kepala Burung PSC.

Upon completion of drilling at Karim-1, the rig will be mobilised for drilling the Northwest Klagagi-1 exploration well.

This well is situated roughly 15 km north-east of the Arar production cluster and around 12 km from the Karim-1 well area.

RH Petrogas group CEO and executive director Francis Chang said: “We are excited to commence the drilling of our two back-to-back exploration wells in the Kepala Burung PSC.

“Preparations have been under way since 2024, including securing the requisite environmental and forestry permits, procurement and site preparation, and upgrading of the drilling rig to enhance its capacity and reliability."

Chang added: “The two wells are located in a remote but prospective area in the eastern part of the Arar block, and drilling them back-to-back will significantly reduce rig mobilisation and ancillary logistics costs.”

RH Petrogas is a Singapore-based independent upstream oil and gas company involved in resource development and production, with a focus on the Association of Southeast Asian Nations region.
