據(jù)海上能源5月9日?qǐng)?bào)道，希臘油氣勘探和生產(chǎn)公司Energean在以色列海上12區(qū)塊發(fā)現(xiàn)了一處商業(yè)天然氣，增強(qiáng)了該公司對(duì)新定義的Olympus區(qū)域潛力的信心。

早在2021年6月，Energean就與Stena Drilling公司簽訂了一個(gè)鉆機(jī)合同，用于其2022年-2023年以色列海上鉆井項(xiàng)目。該公司還在2021年9月與哈里伯頓簽訂了一份執(zhí)行鉆井和完井的綜合服務(wù)合同。

此次鉆探活動(dòng)的目標(biāo)是降低超過10億桶油當(dāng)量的無風(fēng)險(xiǎn)可采資源的風(fēng)險(xiǎn)，計(jì)劃于2022年3月開始。

在周一的更新中，Energean透露，在位于A、B和C砂層的12區(qū)塊Athena勘探井中發(fā)現(xiàn)了一個(gè)商業(yè)天然氣，并解釋稱，對(duì)Athena發(fā)現(xiàn)的初步分析表明，該發(fā)現(xiàn)單獨(dú)包含80億立方米天然氣(2830億立方英尺/ 5100萬桶油當(dāng)量)。

Energean首席執(zhí)行官M(fèi)athios Rigas表示：“我們很高興地宣布，在Athena發(fā)現(xiàn)了新的天然氣，以及更廣闊的Olympus區(qū)域的潛力。我們正在考慮一系列戰(zhàn)略商業(yè)化選擇，包括獨(dú)立的和更廣泛的Olympus區(qū)域開發(fā)，包括國(guó)內(nèi)和多個(gè)出口路線。”

該公司指出，這一發(fā)現(xiàn)尤其重要，因?yàn)樗薕lympus區(qū)域平均500億立方米(相當(dāng)于1.8萬億立方英尺/ 3.21億桶油當(dāng)量)的潛在資源風(fēng)險(xiǎn)，包括Athena勘探井的總共580億立方米資源（3.72億桶油當(dāng)量），還包括12區(qū)塊和鄰近的Tanin Lease的未鉆勘探區(qū)。

Energean擁有Athena勘探井100%的權(quán)益，該勘探井位于12區(qū)塊，距離Karish井20公里，距離Tanin A井20公里，水深1769米。Stena Icemax鉆井船是一艘冰級(jí)惡劣環(huán)境活動(dòng)動(dòng)態(tài)定位鉆井船，能夠在水深達(dá)10000英尺的水中進(jìn)行鉆井作業(yè)，耗時(shí)51天，預(yù)算低于3500萬美元。

Athena井是該公司在以色列連續(xù)第五個(gè)成功鉆探的井。鉆井結(jié)果顯示，在主要目標(biāo)(A、B和C砂層)發(fā)現(xiàn)了156米的總烴柱。Energean打算進(jìn)行額外的分析，以進(jìn)一步提煉全部資源潛力——包括主要儲(chǔ)層單元之間的薄砂中所含的體積——并確認(rèn)發(fā)現(xiàn)的液體含量。

該井已被暫停作為未來的生產(chǎn)井，而在更深的次級(jí)目標(biāo)D砂層中沒有發(fā)現(xiàn)商業(yè)碳?xì)浠衔?，成功的概率?2%。

該公司還表示，Athena油田的發(fā)現(xiàn)可以在近期內(nèi)通過回接Energean Power號(hào)浮式生產(chǎn)儲(chǔ)卸油船實(shí)現(xiàn)商業(yè)化，該浮式生產(chǎn)儲(chǔ)卸油船于本月早些時(shí)候從新加坡起航。Energean認(rèn)為，回接將提高Karish-Tanin油田開發(fā)的盈利能力。Karish項(xiàng)目預(yù)計(jì)將于2022年第三季度生產(chǎn)第一批天然氣。

Athena新發(fā)現(xiàn)將作為Olympus區(qū)域開發(fā)的一部分

作為解決方案的替代方案，Energean表示，Athena新發(fā)現(xiàn)可能成Olympus區(qū)域開發(fā)新的一部分，因?yàn)樵摴菊e極尋求更廣泛的Olympus區(qū)域商業(yè)化開發(fā)方案，例如進(jìn)一步的以色列國(guó)內(nèi)天然氣銷售和出口方案。

此外，這一地區(qū)的發(fā)現(xiàn)和前景沿著相同的地質(zhì)走向，Athena井是在與Tanin井相同的直接碳?xì)浠衔镏甘疚锷香@探的——如地震分析所示。

在天然氣銷售方面，這包括新的天然氣銷售和購(gòu)買協(xié)議，這得益于以色列電力市場(chǎng)和現(xiàn)貨銷售的持續(xù)增長(zhǎng)。Energean還補(bǔ)充說，公司于2022年3月與以色列電氣公司簽署了一份現(xiàn)貨合同。

另一方面，出口選項(xiàng)包括制定與埃及天然氣控股公司于2021年12月簽署的合同，在10年的時(shí)間內(nèi)平均每年供應(yīng)30億立方米天然氣，形成一項(xiàng)具有約束力的協(xié)議，通過管道從塞浦路斯向其他區(qū)域和歐洲市場(chǎng)出口液化天然氣。

Energean解釋道，第12區(qū)塊生產(chǎn)和銷售的天然氣的經(jīng)濟(jì)效益不需要支付給Karish和Tanin租約的原始賣方特許權(quán)使用費(fèi)，與Karish和Tanin發(fā)現(xiàn)的天然氣相比，該區(qū)塊的銷售收入增加了約8%。

Rigas補(bǔ)充說：“這一發(fā)現(xiàn)以及Olympus區(qū)域勘探前景的降低，再次確認(rèn)了東地中海地區(qū)作為全球天然氣勘探熱點(diǎn)的地位。它加強(qiáng)了我們?yōu)樵摰貐^(qū)提供競(jìng)爭(zhēng)和供應(yīng)安全的承諾，使我們能夠優(yōu)化以色列的投資組合，并實(shí)現(xiàn)了我們2022年的一個(gè)關(guān)鍵里程碑?！?/p>

Energean將繼續(xù)其鉆探活動(dòng)

據(jù)Energean稱，Stena IceMAX目前已轉(zhuǎn)移至Karish Main-04評(píng)價(jià)井，頂部井眼已鉆完。之后，該鉆井平臺(tái)預(yù)計(jì)將完成Karish North開發(fā)井。

該公司進(jìn)一步表示，關(guān)于Hermes以及Hercules勘探井鉆探的決定預(yù)計(jì)將于2022年第二季度末做出。

New gas discovery for Energean off Israel

Hydrocarbon exploration and production company Energean has made a commercial gas discovery in Block 12 offshore Israel, bolstering its beliefs in the potential of the newly defined Olympus Area.

Back in June 2021, Energean contracted a rig from Stena Drilling for its 2022 – 2023 growth drilling programme offshore Israel. The firm also booked Halliburton in September 2021 under an integrated services contract to execute the well drilling and completions.

The beginning of this drilling campaign, targeting the derisking of unrisked prospective recoverable resources of over 1 billion barrels of oil equivalent (boe), was scheduled for March 2022.

n an update on Monday, Energean revealed that a commercial gas discovery has been made within the Athena exploration well in Block 12, in the A, B and C sands, explaining that the preliminary analysis of the Athena discovery indicates that it contains recoverable gas volumes of 8 bcm (283 bcf/51 mmboe) on a standalone basis.

Mathios Rigas, Chief Executive of Energean, commented: “We are delighted to announce this new gas discovery at Athena and the potential of the wider Olympus Area. We are considering a range of strategic commercialisation options both for a standalone and wider Olympus Area development, including domestic and multiple export routes.”

The company pointed out that this discovery is particularly significant as it de-risks an additional 50 bcm (1.8 tcf/321 mmboe) of mean unrisked prospective resources across its Olympus Area – total 58 bcm/372mmboe including Athena – which includes not only Athena but also the undrilled prospects on Block 12 and the adjacent Tanin Lease.

Energean holds 100 per cent interest in the Athena exploration well, which was drilled on Block 12, located 20 kilometres from Karish and 20 kilometres from Tanin A, in a water depth of 1,769 metres. The Stena Icemax drillship – an ice-class harsh environment dual-activity dynamically positioned drillship, capable of drilling in water depths of up to 10,000 ft – carried out the drilling operations, which took 51 days and came in below the budget of $35 million.

The Athena well is the fifth one in a row that the company drilled successfully in Israel. The well results show a gross hydrocarbon column of 156 metres was encountered in the primary target (the A, B and C sands). Energean intends to undertake additional analysis to further refine the full resource potential – including volumes contained within thinner sands between the main reservoir units – and to confirm the liquids content of the discovery.

The well has been suspended as a future production well while no commercial hydrocarbons were discovered in the deeper secondary target D sands with a 22 per cent probability of success.

The firm also informed that the Athena discovery can be commercialised in the near term via tie-back to the Energean Power FPSO, which sailed away from Singapore earlier this month. Energean believes that the tie-back would enhance the profitability of the Karish-Tanin development. The Karish project is expected to produce the first gas in the third quarter of 2022.

Athena discovery as part of Olympus Area development

As an alternative to the tie-back solution, Energean stated that the Athena discovery could form part of a new Olympus Area development, as the firm is actively pursuing development options for the commercialisation of the wider Olympus Area, such as further domestic Israeli gas sales and export options.

Furthermore, the discoveries and prospects in this area lie along the same geological trend and Athena was drilled on the same direct hydrocarbon indicator – shown in the seismic analysis – as Tanin.

When it comes to gas sales, this includes new gas sales and purchase agreements (GSPA) underpinned by the continued growth of the Israeli power market and spot sales. Energean further added a spot contract was signed with the Israel Electric Corporation (IEC) in March 2022.

On the other hand, export options entail developing the Memorandum of Understanding (MoU) signed with the Egyptian Natural Gas Holding Company (EGAS) in December 2021 for the supply of up to 3 Bcm/yr of natural gas on average for a period of 10 years into a binding agreement along with exports to other regional and European markets via pipeline and LNG via Cyprus and/or Egypt.

Energean elaborated that the economics of gas produced and sold from Block 12 are not subject to royalties payable to the original sellers of the Karish and Tanin leases, leading to an approximate 8 per cent increase in revenue for the same volumes sold, when compared with the Karish and Tanin discoveries.

“This discovery and the broader de-risking of a number of prospects in the Olympus Area reaffirms the role of the East Mediterranean as a global gas exploration hotspot. It strengthens our commitment to provide competition and security of supply to the region, enables the optimisation of our Israel portfolio and fulfils one of our key milestones for 2022,” added Rigas.

Energean continues its drilling campaign

According to Energean, the Stena IceMAX has now moved to the Karish Main-04 appraisal well, and the top hole has already been drilled. Afterwards, the rig is expected to complete the Karish North development well.

The company further stated that a decision regarding the drilling of the optional exploration wells – Hermes and/or Hercules – is expected to be made by the end of the second quarter of 2022.
