Kosmos在毛里塔尼亚附近发现大量天然气

据世界天然气10月28日消息，总部位于达拉斯的Kosmos能源公司表示，Orca-1探井在毛里塔尼亚近海的BirAllah地区获得了一个重要的天然气发现。

Kosmos在周一的声明中表示，在毛里塔尼亚/塞内加尔，针对船内天然气趋势的9口井取得了100%的成功率。

Orca-1探井针对的是此前未经测试的Albian前景区，在优质储层中发现了36米的天然气净产量，超出了钻探前的预期。此外，该井相对于原先在背斜顶部钻凿的Marsouin-1发现井，在下部构造位置确定了11米的净气产层，从而扩展了Cenomanian 前景区。

Orca-1的位置距离背斜顶部约7.5公里，证明了Orca远景的构造和地层圈闭，Kosmos估计Orca远景的初始平均天然气储量(GIIP)为13万亿立方英尺。

总体而言，Kosmos相信Orca-1和Marsouin-1已经从Cenomanian和Albian前景区的BirAllah地区解锁了50万亿立方英尺的GIIP，这足以支持一个世界级的LNG项目。

此外，在该区域和周围结构中，还发现了更深的未经测试的Aptian前景区。

在评价Orca-1探井的结果时，公司董事长兼首席执行官Andrew Inglis 说道：“Orca-1探井在毛里塔尼亚和塞内加尔的勘探和评估结果证明了这是收获颇丰的一年。我们认为，Orca-1是今年迄今为止世界上最大的深水油气发现，进一步证明了毛里塔尼亚天然气盆地的世界级品质。”

根据钻探结果和Orca-1发现的规模和重要性，Kosmos将其毛里塔尼亚/塞内加尔区块出售过程的时间表延长至2020年，为潜在竞标者提供了更多时间来分析新数据。

Orca-1探井位于毛里塔尼亚近海约125公里处，井深约2510米，总测量水深约5266米。

位于毛里塔尼亚近海的BirAllah天然气枢纽的合作伙伴包括SMHPM、BP和Kosmos。

Kosmos makes major gas find off Mauritania

Dallas-based Kosmos Energy said that the Orca-1 exploration well has made a major gas discovery offshore Mauritania in the BirAllah area.

The results continue the 100 percent success rate from nine wells targeting the inboard gas trend in Mauritania/Senegal, Kosmos said in its statement align="justify">The Orca-1 well, which targeted a previously untested Albian play, exceeded pre-drill expectations encountering 36 meters of net gas pay in excellent quality reservoirs. In addition, the well extended the Cenomanian play fairway by confirming 11 meters of net gas pay in a down-structure position relative to the original Marsouin-1 discovery well, which was drilled align="justify">The location of Orca-1, approximately 7.5 kilometers from the crest of the anticline, proved both the structural and stratigraphic trap of the Orca prospect, which Kosmos estimates has a mean gas initially in place (GIIP) of 13 TCF.

In total, Kosmos believes that Orca-1 and Marsouin-1 have de-risked up to 50 TCF of GIIP from the Cenomanian and Albian plays in the BirAllah area, more than sufficient resource to support a world-scale LNG project.

In addition, a deeper, untested Aptian play has also been identified within the area and surrounding structures.

Following the drilling results and due to the scale and materiality of the Orca-1 discovery, Kosmos is extending the timeline of its Mauritania/Senegal sell-down process into 2020, giving potential bidders additional time to analyze the new data.

Located approximately 125 kilometers offshore Mauritania, the Orca-1 well was drilled in approximately 2,510 meters of water to a total measured depth of around 5,266 meters.

Partners in the BirAllah gas hub, located offshore Mauritania, include SMHPM, BP, and Kosmos.
