2023年初，作為位于設(shè)得蘭西部206/05c區(qū)塊的Benriach油井的運(yùn)營(yíng)商，TotalEnergies確認(rèn)了在2023年第2季度初開鉆該井的決定。為此，簽訂了一份鉆機(jī)合同，預(yù)計(jì)該鉆機(jī)將在初夏鉆探。
在2023年3月29日星期三的最新消息中，TotalEnergies的合作伙伴Kistos透露，Benriach探井是由Transocean的Transocean Barents半潛式鉆井平臺(tái)開鉆的。該井的目標(biāo)P50遠(yuǎn)景資源量為638 Bcf(160 Bcf或Kistos凈2800萬(wàn)桶油當(dāng)量)。
據(jù)Kistos介紹，該井預(yù)計(jì)將于2023年第三季度完工。Kistos的稅后凈干孔成本預(yù)計(jì)約為250萬(wàn)英鎊，這是由于該公司的納稅狀況和能源利潤(rùn)稅提高的投資補(bǔ)貼。
Kistos執(zhí)行主席Andrew Austin表示：“我們對(duì)Benriach油井正在進(jìn)行感到興奮。這對(duì)公司來(lái)說(shuō)是一個(gè)重要的里程碑，有可能增加大量?jī)?chǔ)量。我期待著在適當(dāng)?shù)臅r(shí)候向利益相關(guān)者更新油井的結(jié)果。”
2009年建造的Transocean Barents鉆井平臺(tái)采用Aker H-6e設(shè)計(jì)。它是在阿克-克瓦納-斯托德建造的，可容納140人。該鉆機(jī)能夠在高達(dá)10000英尺的水深下作業(yè)，最大鉆井深度為30000英尺。
作為提醒，TotalEnergies于2022年1月披露了將其在多個(gè)氣田的部分權(quán)益出售給Kistos的決定。該交易于2022年7月完成，當(dāng)時(shí)Kistos透露，它已經(jīng)收購(gòu)了大拉格根地區(qū)(GLA)和相關(guān)基礎(chǔ)設(shè)施20%的權(quán)益，以及某些其他勘探許可證的各種權(quán)益，包括Benriach油田25%的權(quán)益。
位于設(shè)得蘭群島西北125公里處的大拉格根地區(qū)油田——拉格根、托莫爾、埃德拉多爾和格倫利特——位于約300至625米的水深。
另一方面，之前預(yù)計(jì)將于2022年底做出關(guān)于格倫德羅納赫油田的開發(fā)決定，預(yù)計(jì)將于2023年晚些時(shí)候做出，以便進(jìn)行進(jìn)一步的技術(shù)審查，以降低成本。

French energy giant TotalEnergies has started drilling a prospect off the coast of the United Kingdom (UK), using one of Transocean’s semi-submersible rigs.
At the start of 2023, TotalEnergies, as the operator of the Benriach well located in Block 206/05c West of Shetland, confirmed the decision to spud the well early in 2Q 2023. To this end, a contract for a rig, which was expected to drill the well in early summer, was inked.
In an update on Wednesday, 29 March 2023, TotalEnergies’ partner, Kistos, disclosed that the Benriach exploration well was spudded by Transocean’s Transocean Barents semi-submersible rig. The well is targeting P50 prospective resources of 638 Bcf (160 Bcf or 28mmboe net to Kistos).
According to Kistos, the well is expected to complete in 3Q 2023. The dry hole post-tax cost net to Kistos is forecast to be about £2.5 million as a result of the firm’s tax-paying position and the enhanced investment allowances from the Energy Profits Levy.
Andrew Austin, Kistos’ Executive Chairman, remarked: “We are excited that the Benriach well is underway. It is an important milestone for the company with the potential to add significant reserves. I look forward to updating stakeholders with the results of the well in due course.”
The 2009-built Transocean Barents rig is of Aker H-6e design. It was constructed at Aker Kvaerner Stord and can accommodate 140 people. The rig is capable of operating in water depths of up to 10,000 ft and its maximum drilling depth is 30,000 ft.
As a reminder, TotalEnergies’ decision to sell some of its interests in multiple gas fields to Kistos was disclosed in January 2022. The deal was completed in July 2022 when Kistos revealed that it had acquired a 20 per cent interest in the Greater Laggan Area (GLA) and associated infrastructure alongside various interests in certain other exploration licences, including a 25 per cent interest in the Benriach prospect.
Located up to 125 km northwest of the Shetland Islands, the producing Greater Laggan Area fields – Laggan, Tormore, Edradour and Glenlivet – are situated in water depths of approximately 300 to 625 metres.
On the other hand, the development decision regarding the Glendronach field, which was previously anticipated by the end of 2022, is expected to be taken later in 2023 to allow further technical reviews to be undertaken with the aim of reducing costs.
