Equinor在北海發(fā)現(xiàn)天然氣和凝析油

據(jù)OE網(wǎng)站7月8日?qǐng)?bào)道，挪威油氣公司Equinor在位于挪威近海的北海亞特蘭蒂斯30/2-5S號(hào)探井中發(fā)現(xiàn)了天然氣和凝析油。

該發(fā)現(xiàn)是在北海Kvitebj?rn油田以南約17公里，卑爾根西北160公里處發(fā)現(xiàn)的。

根據(jù)初步估計(jì)，探明儲(chǔ)量在300萬(wàn)-1000萬(wàn)標(biāo)準(zhǔn)立方米的可采石油當(dāng)量，相當(dāng)于1900萬(wàn)-6300萬(wàn)桶石油當(dāng)量。

Equinor負(fù)責(zé)挪威和英國(guó)勘探的高級(jí)副總裁尼克?阿什頓（Nick Ashton）表示，看到我們能夠在挪威大陸架最成熟的區(qū)域之一繼續(xù)探明更多資源，這是令人鼓舞的。現(xiàn)在，我們將致力于評(píng)估盈利和二氧化碳高效回收的潛力。

30/2-5 S探井的主要勘探目的是探明Brent組中侏羅系儲(chǔ)層的油氣。該井遇到了160米高的氣柱，其中60米代表了有效的中侏羅世儲(chǔ)層巖石。Ness、Etive、Tarbert組儲(chǔ)層質(zhì)量欠佳，Rannoch組儲(chǔ)層質(zhì)量較差。

雖然沒(méi)有對(duì)該井進(jìn)行地層測(cè)試，但是已經(jīng)獲得了大量的數(shù)據(jù)并采集了樣本。這口井鉆探到海平面以下4359米的垂直深度。該地區(qū)的水深為142米。這口井被永久地堵住并廢棄了。

這是生產(chǎn)許可區(qū)878中要鉆的首個(gè)勘探井。 該許可證在2016年預(yù)定地區(qū)授予(APA2016)中獲得。 該許可持有單位會(huì)在整體評(píng)估該地區(qū)時(shí)，考慮是否繼續(xù)進(jìn)行有關(guān)發(fā)現(xiàn)。

該井是由西赫拉克勒斯（West Hercules）鉆機(jī)鉆探的，該鉆機(jī)正繼續(xù)在生產(chǎn)許可區(qū)248 C鉆探35 / 11-24 S勘探井，這是一個(gè)名為Swisher的勘探區(qū)。

生產(chǎn)許可區(qū)878的所有者是Equinor Energy(60%)、Source Energy(20%)和Wellesley Petroleum(20%)。

Equinor Finds Gas and Condensate at Atlantis Well in North Sea

Norwegian oil and gas company Equinor has discovered gas and condensate in the exploration well 30/2-5 S Atlantis, in the North Sea, offshore Norway.

The discovery was made about 17 kilometers south of the Kvitebj?rn field in the North Sea and 160 kilometers northwest of Bergen.

Based on preliminary estimates the proven reserves are between 3 and 10 million standard cubic meters of recoverable oil equivalent, corresponding to 19-63 million barrels of oil equivalent.

Nick Ashton, Equinor’s senior vice president for exploration in Norway and the UK: “It is encouraging to see that we are able to keep proving more resources in one of the most mature areas on the Norwegian continental shelf. Now we will work on evaluating the potential for profitable and CO2 efficient recovery.

The primary exploration target of exploration well 30/2-5 S was to prove hydrocarbons in the Middle Jurassic reservoir of the Brent Group. The well encountered about a 160-meter high gas column, of which 60 meters represent an effective Middle Jurassic reservoir rock. Poor to satisfactory reservoir quality was encountered in the Ness, Etive, and Tarbert formation, while the Rannoch formation had poor reservoir quality.

The well was not formation tested however extensive amounts of data have been acquired and samples have been taken. The well was drilled to a vertical depth of 4359 meters below sea level. Water depth in the area is 142 meters. The well was permanently plugged and abandoned.

This is the first exploration well to be drilled in production license 878. The license was awarded in the Awards in Predefined Areas 2016 (APA 2016). The licence owners will consider whether to pursue the discovery in an overall assessment of the area.

The well was drilled by the West Hercules drilling rig, which is moving on to drill the exploration well 35/11-24 S, a prospect named Swisher, in production license 248 C.

The license owners of production license 878 are Equinor Energy AS (60%), Source Energy (20%), and Wellesley Petroleum AS (20%).
