Equinor 在巴伦支海“Naseras”勘探区的 7220/2-2 号井目前处于干涸状态。

该井由 Transocean Enabler 钻井平台钻探，位于 1080 号生产许可证内，该许可证于 2020 年在预定义区域 (APA) 奖项中获奖。2014

年，Equinor 及其合作伙伴在“Naseras”井以北发现了“Sfjell”(7220/2-1) 天然气。

在“Naseras”以南的 532 号生产许可证内，同一合作伙伴也发现了多个天然气。这些发现正在考虑与 Johan Castberg 油田进行整合，后者计划于 2024 年底开始生产。

地质信息

该探井的目标是探明 St 酶地层中侏罗纪早期储层岩石中的石油。

该井遇到了总厚度约为 66 米的 St 酶地层，其中 63 米为砂岩，储层质量非常好。该井被归类为干井，含有碳氢化合物痕迹。

7220/2-2 井的垂直深度为海平面以下 821 米，终止于早侏罗世的 Nordmela 地层。

现场水深为 427 米。该井将被永久封堵并废弃。

Equinor’s well 7220/2-2 in the “Snøras” prospect in the Barents Sea is dry.

The well, drilled by the Transocean Enabler rig, is located in production licence 1080, which was awarded in the Awards in Predefined Area (APA) in 2020.

In 2014, Equinor and the partners made the “Isfjell” (7220/2-1) gas discovery, just to the north of the “Snøras” well.

In production licence 532, south of “Snøras”, the same partnership has made multiple discoveries. These discoveries are being considered for tie-back to the Johan Castberg field, where production start is planned for late 2024.

Geological information

The objective of the wildcat well was to prove petroleum in Early Jurassic reservoir rocks in the Stø Formation.

The well encountered the Stø Formation with a total thickness of around 66 metres, 63 metres of which was sandstone with very good reservoir quality. The well is classified as dry with traces of hydrocarbons.

Well 7220/2-2 was drilled to a vertical depth of 821 metres below sea level, and was terminated in the Nordmela Formation in the Early Jurassic.

Water depth at the site is 427 metres. The well will be permanently plugged and abandoned.
