俄罗斯石油公司在萨哈林岛近海发现石油

据油气新闻10月8消息称，俄罗斯综合能源公司俄罗斯石油公司表示，它已在俄罗斯近海萨哈林岛架子上的沃斯托奇诺-普里布雷日尼许可证区完成了第一口探井和评估井的钻探工作。

该井是由俄罗斯石油公司自己的钻井承包商RN-Burenie如期钻探，测量深度为3047米；垂直偏差为1450米。俄罗斯石油公司表示，在困难的地质条件下钻探过程中，为了最优地发现所有预定目标，他们设计了一个S形路径的井，可以钻两个孔。在井孔中进行的一系列地球物理研究证实了生产层的油饱和度。

俄罗斯石油公司表示，它正准备对油井进行套管测试，初步估计储量最高可达200万吨石油，这些石油将列入2019年的国家资产负债表。

俄罗斯石油公司表示，在许可区钻的第一口井证实了该公司地质学家早些时候对整个区域1100万吨油当量资源潜力的预测。

该公司拥有在俄罗斯勘探55个离岸油田的许可证。该公司表示，计划晚些时候决定新油田的开发和投产时间。

沃斯托奇诺-普里布雷日尼许可证位于鄂霍次克海的纳比尔斯基湾。2016年12月，区块内油气勘探开发生产许可证正式颁发。

Rosneft Makes Discovery Offshore Sakhalin

Russian integrated energy company Rosneft said it has completed drilling the first prospecting and appraisal well at the Vostochno-Pribrezhny license block on the shelf of Sakhalin Island, offshore Russia.

The well was drilled on-schedule by Rosneft’s own drilling contractor RN-Burenie to a measured depth of 3,047 meters; the vertical deviation was 1,450 meters. A well design that provided for drilling two holes with S-shaped paths was developed for optimal discovery of all intended targets in the course of drilling in difficult geological conditions, Rosneft said. A set of geophysical studies in the open hole confirmed the oil saturation of productive formations.

Rosneft said it is preparing to test the well in casing, and preliminary estimates indicate reserves up to 2 million metric tons of oil, which will be included in the 2019 state balance sheet.

The first well drilled in the license area confirms the forecast made earlier by the company’s geologists for the resource potential of the entire area of 11 million metric tons of oil equivalent, Rosneft said.

The company, which possesses licenses for the exploration of 55 offshore sites in Russia, said it plans to decide on the timing of development and commissioning of the new field at a later date.

Vostochno-Pribrezhny is located in the Nabilsky Bay of the Sea of Okhotsk. The license for geological exploration, development, and production of hydrocarbons in the license block was issued in December 2016.
