希腊Energean在以色列附近气田获得新发现

据海上能源5月9日报道,希腊油气勘探和生产公司Energean在以色列海上12区块发现了一处商业天然气,增强了该公司对新定义的Olympus区域潜力的信心。

早在2021年6月,Energean就与Stena Drilling公司签订了一个钻机合同,用于其2022年-2023年以色列海上钻井项目。该公司还在2021年9月与哈里伯顿签订了一份执行钻井和完井的综合服务合同。

此次钻探活动的目标是降低超过10亿桶油当量的无风险可采资源的风险,计划于2022年3月开始。

在周一的更新中,Energean透露,在位于A、B和C砂层的12区块Athena勘探井中发现了一个商业天然气,并解释称,对Athena发现的初步分析表明,该发现单独包含80亿立方米天然气(2830亿立方英尺/ 5100万桶油当量)。

Energean首席执行官Mathios Rigas表示:“我们很高兴地宣布,在Athena发现了新的天然气,以及更广阔的Olympus区域的潜力。我们正在考虑一系列战略商业化选择,包括独立的和更广泛的Olympus区域开发,包括国内和多个出口路线。”

该公司指出,这一发现尤其重要,因为它消除了Olympus区域平均500亿立方米(相当于1.8万亿立方英尺/ 3.21亿桶油当量)的潜在资源风险,包括Athena勘探井的总共580亿立方米资源(3.72亿桶油当量),还包括12区块和邻近的Tanin Lease的未钻勘探区。

Energean拥有Athena勘探井100%的权益,该勘探井位于12区块,距离Karish井20公里,距离Tanin A井20公里,水深1769米。Stena Icemax钻井船是一艘冰级恶劣环境活动动态定位钻井船,能够在水深达10000英尺的水中进行钻井作业,耗时51天,预算低于3500万美元。

Athena井是该公司在以色列连续第五个成功钻探的井。钻井结果显示,在主要目标(A、B和C砂层)发现了156米的总烃柱。Energean打算进行额外的分析,以进一步提炼全部资源潜力——包括主要储层单元之间的薄砂中所含的体积——并确认发现的液体含量。

该井已被暂停作为未来的生产井,而在更深的次级目标D砂层中没有发现商业碳氢化合物,成功的概率为22%。

该公司还表示,Athena油田的发现可以在近期内通过回接Energean Power号浮式生产储卸油船实现商业化,该浮式生产储卸油船于本月早些时候从新加坡起航。Energean认为,回接将提高Karish-Tanin油田开发的盈利能力。Karish项目预计将于2022年第三季度生产第一批天然气。

Athena新发现将作为Olympus区域开发的一部分

作为解决方案的替代方案,Energean表示,Athena新发现可能成Olympus区域开发新的一部分,因为该公司正积极寻求更广泛的Olympus区域商业化开发方案,例如进一步的以色列国内天然气销售和出口方案。

此外,这一地区的发现和前景沿着相同的地质走向,Athena井是在与Tanin井相同的直接碳氢化合物指示物上钻探的——如地震分析所示。

在天然气销售方面,这包括新的天然气销售和购买协议,这得益于以色列电力市场和现货销售的持续增长。Energean还补充说,公司于2022年3月与以色列电气公司签署了一份现货合同。

另一方面,出口选项包括制定与埃及天然气控股公司于2021年12月签署的合同,在10年的时间内平均每年供应30亿立方米天然气,形成一项具有约束力的协议,通过管道从塞浦路斯向其他区域和欧洲市场出口液化天然气。

Energean解释道,第12区块生产和销售的天然气的经济效益不需要支付给Karish和Tanin租约的原始卖方特许权使用费,与Karish和Tanin发现的天然气相比,该区块的销售收入增加了约8%。

Rigas补充说:“这一发现以及Olympus区域勘探前景的降低,再次确认了东地中海地区作为全球天然气勘探热点的地位。它加强了我们为该地区提供竞争和供应安全的承诺,使我们能够优化以色列的投资组合,并实现了我们2022年的一个关键里程碑。”

Energean将继续其钻探活动

据Energean称,Stena IceMAX目前已转移至Karish Main-04评价井,顶部井眼已钻完。之后,该钻井平台预计将完成Karish North开发井。

该公司进一步表示,关于Hermes以及Hercules勘探井钻探的决定预计将于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.
