活动头条

中石化在四川盆地发现页岩气

中国石化宣布四川盆地綦江页岩气田取得重大发现,探明储量145968MMcm。这一发现是由中国石化勘探公司和中国石化西南油气公司发现的。

綦江页岩气田是盆地边缘复杂构造带中、深层发现的第一个页岩气田。埋藏深度超过3500m的页岩气为深层页岩;綦江页岩地层埋深1900~4500m,以深层页岩为主。

为了解决地表和地下条件复杂的盆地边缘页岩气藏是如何形成的问题,中国石化团队在1320m深度进行了10000余次岩心室内分析测试。测试表明,深层页岩可以发育高孔隙度的广阔储层,包括甜点区。

该团队收集了四川盆地东南缘3662平方公里范围内的3D地震数据以及川南现有井的钻井数据。

中国石化表示,已开发出深层页岩气地震预测技术,通过压力系数和含气量、裂缝预测和地面水平应力差来预测深层页岩气甜点。中石化还表示,开发了深层页岩精准切割、增压膨胀、平衡膨胀、保证充注的3D压裂技术,提高了页岩气井日产量。

Westwood:2023 年北海半利用“鼓舞人心”

在 7 月达到峰值后,北海的半利用率已降至 78%。即便如此,尽管 Westwood 称 2023 年的需求前景“令人鼓舞”,但今年的奖励活动还是有所增加。

韦斯特伍德表示,总体而言,北海半基础设施正在改善,但更多钻井平台仍可能离开该地区。

根据 Westwood 的 RigLogix 的数据,2015 年 1 月至 2022 年 11 月期间,北海半成品供应量减少了 36%,即 17 台,原因是这些设备的需求长期缺乏,尤其是在更成熟的英国行业。半成品市场仍然具有季节性,春季和夏季的利用率较高,而恶劣天气期间的利用率较低。

然而,到 2022 年 7 月,钻机部分的承诺利用率达到 90%,这是该地区自 2015 年 6 月以来记录的最高数字。进入冬季,需求随后下降,利用率降至 78%,目前有 9 台设备闲置该公司表示,包括两个冷堆单元。

Westwood 表示,由于世界上许多其他地区目前承诺的钻机利用率持续保持在 90% 左右的高位,而西北欧则落后,因此越来越多的设备正在离开欧洲或在该地区之外投标,以获得期限更长、日费潜力更高的新合同。该公司表示,北海自升式钻井平台也是如此。

2022年第三季度,北海半成品市场固定合同积压天数为3,899天,这是自2012年以来单季度固定天数最高的。平均合同持续时间也在上升,目前为264天今年迄今为止,这也是自 2012 年以来最长的一次。

然而,该公司指出,今年迄今已批准的 37% 的积压订单至少要到 2024 年才会开始,而目前 2023 年北海半成品的明显需求看起来并不那么有希望。

RigLogix 目前记录了 2023 年可能授予的工作的未完成需求近 2,000 天,包括预招标、招标和直接谈判。此外,预计还有大约 2,300 天的工作需求尚未招标。

这一未完成需求相当于总共超过 4,260 天的潜在工作时间,比 2024 年可见需求前景减少了近 64%。此外,该未完成需求的平均合同期限仅为 171 天,比 2024 年的可见需求前景短了约 43%。今年的当前数字。

由于政府在 2020 年实施的税收激励措施,Westwood 预计 2024 年挪威的几项新开发项目将取得进展。与此同时,英国可能会启动各种长期活动,包括堵塞和废弃(P&A) 工作以及开发项目。

该细分市场的市场基本面显示出市场趋紧的潜力,但可能要到 2024 年才会出现,除非 2023 年出现进一步的需求。当然,这将取决于其他因素,例如对英国石油和天然气利润额外增加暴利税的反应,以及挪威政府计划逐步取消作为其税收减免计划的一部分而推出的税收减免计划。 2020 年应对 COVID-19 危机。

韦斯特伍德相信,在市场收缩之前,钻井承包商将继续评估其在其他地区的恶劣环境资产的机会。

Naftogaz 与哈里伯顿加强合作

Naftogaz 集团在与哈里伯顿举行会晤后宣布,将加强与哈里伯顿的合作,以释放乌克兰油田的潜力。

2018年,哈里伯顿开始为Naftogaz Group的Ukrgasvydobuvannya提供侧线服务,帮助该公司实现了显着的额外产量,主要是在老油井和枯竭油田。

Naftogaz 表示,现在,Ukrgasvydobuvannya 对水平钻井技术感兴趣。

监管更新

NSTA 在英国北海启动火炬燃烧调查

北海过渡管理局(NSTA)宣布,已对一家石油和天然气公司在未经同意的情况下在英国北海燃烧和排放的行为展开调查。

NSTA表示,调查结束后,该公司可能会被罚款或吊销相关生产许可证。

2018-20 年间,火炬燃烧和放空占英国北海石油和天然气生产活动排放量的 26%,减少这些排放将有助于实现北海过渡协议中商定的减排目标并减少天然气浪费。

《北海过渡协议》承诺,到 2030 年,行业生产运营排放量将比 2018 年基准减少至少 50%,并在 2050 年实现净零排放。

NSTA 于 2021 年 3 月提出了净零管理期望,要求运营商在整个项目生命周期中表明其减少温室气体排放的承诺。

随后在更新的指南中提出了更严格的燃烧和排放方法,其中详细说明了 NSTA 打算利用其同意制度来推动减排,并在可能的情况下消除这两个过程。

“在我们的支持下,北海运营商去年将火炬燃烧量减少了 20%,排放量减少了 22%,”NSTA 临时监管主任 Jane de Lozey 表示。“NSTA 致力于让行业对排放负责,以确保持续取得进展,并准备在我们怀疑一家公司的行为可能会损害达到和超越商定目标的努力时采取行动。”

NSTA 表示,根据 NSTA 的战略,被许可人有义务协助国务卿实现净零目标,同时优化石油和天然气生产以增强供应安全,未经授权的燃烧和排放违反了这一义务。

BSEE 延长太平洋 OCS 退役反馈期限

美国安全与环境执法局 (BSEE) 延长了针对太平洋外大陆架 (OCS) 石油和天然气退役活动起草的计划性环境影响报告书 (PEIS) 的征求意见期。 

“鉴于要求额外时间审查和评估太平洋地区预期海上石油和天然气退役方案的请求数量众多,BSEE 将意见征询期再延长 29 天至 2023 年 1 月 10 日,”Bruce 表示。 Hesson,BSEE 太平洋地区总监。“我们收到的评论将为我们未来在该地区退役的决定提供依据。因此,我们必须给公众充足的时间提供反馈,以帮助确保进行可靠的分析。”

PEIS 将为有关南加州联邦水域海上石油和天然气平台退役申请的决定提供信息。23 23 个 20 世纪 60 年代末至 1990 年间安装的加州 OCS 石油和天然气平台最终将退役。

您可以在 2023 年 1 月 10 日之前通过Regulations.gov或发送电子邮件至BOEM.PAC.decomm.PEIS@boem.gov就 BOEM-2021-0043 提出书面意见。原定截止日期为 11 月 28 日。

From collaborations to new contracts, below is a compilation of the latest headlines in the E&P space within the past week. 

Activity headlines

Sinopec finds shale gas at Sichuan Basin

Sinopec announced a major discovery in the Qijiang shale gas field in the Sichuan Basin, finding 145,968 MMcm of proven reserves. The discovery was by Sinopec Exploration Co. and Sinopec Southwest Oil & Gas Co.

The Qijiang shale gas field is the first shale gas field discovered in medium-deep and deep strata in a complex tectonic zone at the basin margin. Shale gas buried deeper than 3,500 m is considered to be deep shale; the burial depth of Qijiang shale formations ranges from 1,900 m to 4,500 m, with most being deep shale.

To address the question of how a shale gas reservoir was formed at the basin margin with such complex surface and underground conditions, the Sinopec team conducted more than 10,000 core laboratory analysis tests at a depth of 1,320 m. The tests revealed that deep shale can develop broad reservoirs with high porosity, including sweet spots.

The team collected 3D seismic data over an area of 3,662 sq km in the southeastern margin of the Sichuan Basin, as well as drilling data from existing wells in southern Sichuan.

Sinopec said it has devised a deep shale gas seismic prediction technology with pressure coefficient and gas content, fracture prediction and horizontal stress difference in the ground to predict the sweet spots of deep shale gas. Sinopec also said it has developed 3D fracturing technology with precision cutting, pressurization and expansion, balanced expansion and guaranteed filling for deep shale, which it claims has improved daily shale gas production wells.

The contract is expected to begin late in the third quarter or early in the fourth quarter 2023 and has an estimated duration of 320 days. The estimated total contract value, including mobilization fee, is $136.4 million.

Westwood: North Sea semi utilization for 2023 ‘uninspiring’

After peaking in July, semi utilization in the North Sea has dropped to 78%. Even so, award activity this year was up although Westwood called the 2023 demand outlook “uninspiring.”

Overall, North Sea semi fundamentals are improving, but more rigs could still leave the region, according to Westwood.

According to Westwood’s RigLogix, North Sea semi supply shrank by 36%, or by 17 units, between January 2015 and November 2022, following a prolonged lack of demand for these units, especially in the more mature U.K. sector. The semi market remains seasonal, with higher utilization in the spring and summer months and lower utilization during harsher weather.

In July of 2022 however, the rig segment hit committed utilization of 90%, which is the region’s highest figure recorded since June 2015. Moving toward winter, demand has subsequently declined and utilization has dropped to 78%, with nine units currently idle, including two cold stacked units, the firm said.

Because many other regions in the world are now recording consistent committed rig utilization highs around 90%, while Northwest Europe lags, more units are leaving Europe or being bid outside the region for new contracts with longer terms and higher day rate potential, Westwood said. The same can be said for the North Sea jackup segment as well, according to the firm.

During the third quarter of 2022, the North Sea semi market fixed 3,899 days of contract backlog, which is the highest number of days fixed during a single quarter since 2012. The average contact duration is also on the rise and is currently sitting at 264 days year to date, which is also the longest it has been since 2012.

However, 37% of backlog awarded so far this year will not begin until at least 2024 and the current visible outstanding demand for North Sea semis in 2023 doesn’t look quite so promising, the firm noted.

RigLogix currently records just under 2,000 days of demand outstanding for work likely to be awarded in 2023, consisting of pre-tenders, tenders, and direct negotiations. Additionally, there is prospective demand for approximately 2,300 further days of work yet to be tendered.

This outstanding demand equates to a total of just over 4,260 days of potential work, which is almost 64% less than the visible demand outlook for 2024. Additionally, average contract duration of this outstanding demand is just 171 days, around 43% lower than this year’s current figure.

During 2024, Westwood expects to see several new Norwegian developments move ahead because of the tax incentives that were implemented by the government during 2020. Meanwhile, there are a variety of longer-term U.K. campaigns likely to start-up, consisting of plugging and abandonment (P&A) work as well as development projects.

The market fundamentals within this segment are showing potential for a tighter market, but likely not until 2024 unless further demand for 2023 emerges. This will of course depend on other factors, such as the response to the additional hike in windfall tax on U.K. oil and gas profits, as well as the Norwegian government’s plans to phase out its tax relief package that was introduced as part of its response to the COVID-19 crisis in 2020.

Until the market constricts, Westwood believes drilling contractors will continue to assess opportunities for their harsh-environment assets in other regions.

Naftogaz, Halliburton boost cooperation

Naftogaz Group announced it is strengthening its cooperation with Halliburton to unlock the potential of Ukraine’s fields, following a meeting between the two.

In 2018, Halliburton started providing Naftogaz Group’s Ukrgasvydobuvannya with sidetrack services, which helped the company to achieve significant additional production, primarily at old wells and depleted fields.

Now, Ukrgasvydobuvannya is interested in horizontal drilling technology, Naftogaz said.

Regulatory updates

NSTA launches flaring investigation in UK North Sea

The North Sea Transition Authority (NSTA) announced it had launched an investigation into an oil and gas company for flaring and venting in the U.K. North Sea without consent.

Following the investigation, the company could be fined or lose the relevant production license, the NSTA said.

Flaring and venting made up 26% of emissions from oil and gas production activities in the U.K. North Sea between 2018-20—and reducing them will help to meet reduction targets agreed in the North Sea Transition Deal and lower gas waste.

The North Sea Transition Deal commits industry to reduce emissions from production operations by at least 50% by 2030, against a 2018 baseline, on the path to net-zero by 2050.

The NSTA introduced a net-zero stewardship expectation in March 2021, requiring operators to show their commitment to reducing greenhouse gasses throughout the project lifecycle.

A tougher approach to flaring and venting was subsequently set out in updated guidance, which provided details of the NSTA’s intent to use its consenting regime to drive reductions and, where possible, eliminate both processes.

“With our support, North Sea operators cut flaring by 20% and venting by 22% last year,” said Jane de Lozey, NSTA Interim Director of Regulation. “The NSTA is committed to holding industry to account on emissions to ensure progress continues and is prepared to take action where we suspect a company’s actions risk compromising efforts to meet and surpass agreed targets.”

Under the NSTA’s strategy, licensees are obligated to assist the Secretary of State to meet the net zero target while optimizing oil and gas production to bolster supply security, NSTA said, and unauthorized flaring and venting go against this obligation.

BSEE extends Pacific OCS decommissioning feedback deadline

The U.S. Bureau of Safety and Environmental Enforcement (BSEE) has extended the comment period for the drafted programmatic environmental impact statement (PEIS) for oil and gas decommissioning activities on the Pacific Outer Continental Shelf (OCS). 

“Given the number of requests for additional time to review and evaluate options for the anticipated offshore oil and gas decommissioning in the Pacific Region, BSEE is extending the comment period by an additional 29 days to Jan. 10, 2023,” said Bruce Hesson, BSEE Pacific Region Director. “The comments we receive will inform our decisions on future decommissioning in the region. We must therefore give the public ample time to provide feedback, helping to ensure a robust analysis.”

The PEIS will inform decisions on decommissioning applications for offshore oil and gas platforms in federal waters off southern California. 23 California OCS oil and gas platforms installed between the late 1960s and 1990 are subject to eventual decommissioning.

Written comments can be made regarding BOEM-2021-0043 at Regulations.gov or by emailing BOEM.PAC.decomm.PEIS@boem.gov through Jan. 10, 2023. The original deadline was Nov. 28.
