   据海上工程师网2021年10月26日报道,挪威石油和天然气公司Equinor日前在其位于挪威海的Egyptian Vulture海上井获得了一个石油和天然气发现。

  Equinor的合作伙伴Longboat能源公司表示,他们部署在挪威海6407/1-9号勘探井在下白垩统纪森诺曼阶Intra-Lange地层的主要目标区内发现了轻质原油。 这个油藏的顶部在海平面以下3684米,其垂直深度接近预测,在37米厚的总含油层中有13米的净砂层。

  Lange砂岩层孔隙度约为16%。合作伙伴在发现井中进行了大量的数据采集和采样过程,对油样的初步分析表明,这种原油API度非常轻。

  Longboat能源公司说,钻进过程中没有遇到油水接触面。

  Equinor初步估计Egyptian Vulture发现井的可采资源量为1900 万~ 6300万桶油当量,而地质储量估计为2.2亿 ~ 4.4亿桶油当量。

  Equinor Makes Light Oil Discovery in Norwegian Sea

  Norwegian oil and gas company Equinor has made an oil and gas discovery at its Egyptian Vulture offshore well in the Norwegian Sea, off Norway.

  Equinor's partner Longboat Energy said the exploration well 6407/1-9 in the Norwegian Sea encountered light oil in the primary target in the Lower Cretaceous (Cenomanian) Intra-Lange Formation. The top of the reservoir was reached close to prognosis at a vertical depth of 3,684 meters below sea level with 13 meters net sand in a 37-meter oil-filled gross interval.

  The upper part of the Lange sand interval has a high net to gross ratio and porosities in the order of 16 percent. An extensive program of data acquisition and sampling has been carried out and the preliminary analysis of the oil sample indicates a very light oil. The oil-water contact was not encountered, Longboat said.

  Equinor's preliminary estimate of recoverable resources in the Egyptian Vulture discovery is 19 to 63 MMboe (gross) and the oil-in-place volume has been estimated at 220 to 440 MMboe (gross).
