预计未来十年全球天然气需求将上升,从而影响2023年至2030年间产量激增12.5%。然而,Rystad Energy预测,即使在气温升高1.9°C 2.5°C的情况下,可再生能源的快速增长,目前现有的一套气田将无法满足全球需求,需要非常规天然气供应快速增长。中东等天然气资源丰富的地区以及鲁卜哈利等盆地将在弥补这一缺口方面发挥重要作用,预计到 2040 年每年可提供 2000 万吨液化天然气。

近年来,由于技术进步和交货时间缩短,页岩气等非常规天然气的生产经历了快速增长。这种快速增长推动了非常规天然气供应在全球天然气生产中所占的份额,其速度从 2000 年的 4% 上升到 2022 年的 12% 和 2023 年的 35%,之前需要更长的时间才能实现。

来自非常规来源的廉价天然气的涌入以及俄罗斯等出口国的持续供应,抑制了常规天然气的勘探工作。显而易见的是,近 70% 已发现的常规矿藏尚未获得开发批准,这表明开发其中一些发现的障碍和不愿意。

从历史上看,俄罗斯和中东一直主导着常规天然气生产。随着中东国家将增加天然气产量作为其新能源转型战略的一部分,这一趋势不会很快放缓。

“亚洲越来越被认为是实现可持续未来的重要垫脚石。随着减少排放和区域能源安全目标的一致,天然气有望在全球能源转型中发挥关键作用。Rystad Energy 勘探副总裁 Aatisha Mahajan 表示,中东是这一转变的关键驱动力,作为新能源转型战略的一部分,该地区正在慢慢转向开发和增加天然气产量。

拥抱非传统的“Jafurah”,表明区域支点

到2030年,非常规天然气在全球产量中的份额将增至30%以上。非常规产量的预期增长主要是由于过去十年勘探成功率下降以及缺乏开发的常规天然气项目,这表明非常规天然气产量的减少在常规天然气供应总量中。

海湾合作委员会(GCC)地区历来是石油和天然气生产大国。然而,近年来,大型常规发现有所减少,促使该地区国家勘探和开发更多非常规资源。

沙特阿拉伯就是这一转变的典范,该国的目标是到 2030 年将石油从电力生产中消除,并实现 50% 的可再生能源和 50% 的天然气发电比例。这种向更加多元化的能源格局的转变得到了不断增长的天然气需求的支持预计到本十年末,该国每年的排放量将达到 1,250 亿厘米3 。

为了满足不断增长的需求,沙特阿拉伯将需要非伴生气田以及非常规气田的新产量,例如 Jafurah 气田——中东地区面积最大、富含液体的页岩气田,预计生命周期投资超过1000亿美元。Jafurah项目的推动者沙特阿美公司计划到2030年实现页岩气产量峰值达到每天20亿立方英尺。

Rystad Energy估计这一峰值产量目标将在2030年代下半叶实现。届时,该项目将占沙特天然气总产量的近15%,对沙特整体天然气供应产生重大推动作用。

资金需求——发展需要长期供应

到 2030 年代中期,全球天然气需求将上升。然而,目前正在生产和未开发的气田预计将在未来几年达到产量峰值,然后开始下降。即使考虑到所有尚未批准且目前处于发现生命周期类别的领域,在理想情况下仍远未实现峰值生产。

我们对全球变暖情景的分析表明,需要更多的天然气勘探和生产才能满足 1.9 或 2.5° 的变暖。除 1.6 度外,在每种情况下,都需要额外的天然气资源来满足需求。因此,在重要的天然气盆地或天然气资源丰富的国家进行天然气勘探和额外的资本投资是必要的。

非常规天然气将继续在世界供应结构中发挥重要作用,预计到 2030 年将增加到约三分之一。非常规产量的预期增长主要是由于过去十年勘探成功率下降以及缺乏常规天然气项目开发,导致常规天然气供应总量下降。

自 2010 年以来发现的常规天然气量中,只有 32% 正在生产,超过 50% 尚未获得开发批准。因此,依赖传统天然气来源的国家如果不增加生产投资,将不得不转向非常规产量,以实现净零排放目标并满足全球需求。

Rystad Energy: New natural gas production is needed to meet demand

Published by , Deputy Editor
Oilfield Technology,


Global gas demand is projected to rise in the next decade, thus influencing a 12.5% surge in production between 2023 and 2030. However, Rystad Energy forecasts that even in scenarios of 1.9 – 2.5°C warming, with rapid growth in renewable energy sources, the current set of existing gas fields will not meet global demand, requiring rapid growth in unconventional gas supply. Gas-rich geographies such as the Middle East, with basins such as Rub al Khali, will play an essential role in bridging that gap, providing an estimated 20 million tpy of LNG by 2040.

The production of unconventional gas, such as shale, has experienced rapid growth in recent years due to technological advancements and reduced lead times. This rapid growth has driven the global share of unconventional gas supply in global gas production at a pace that has previously required significantly more time to achieve, escalating from 4% in 2000 to 12% in 2022 and 35% in 2023.

The influx of affordable gas from unconventional sources and ongoing supply from exporting countries like Russia has tempered exploration efforts for conventional gas. This is evident in that nearly 70% of discovered conventional volumes have yet to receive sanctions for development, showcasing the hurdles and reluctance to develop some of these finds.

Historically, Russia and the Middle East have dominated conventional gas production. This is not slowing down anytime soon, with Middle Eastern countries ramping up gas volumes as part of their new energy transition strategies.

“Gas is increasingly considered a crucial stepping stone to a sustainable future. With reduced emissions and regional energy security goals aligned, gas is poised to play a pivotal role in the global energy transition. The Middle East is a key driver of this shift, slowly moving into developing and increasing gas volumes as part of their new energy transition strategies,” says Aatisha Mahajan, Vice President of Exploration with Rystad Energy.

Embrace the unconventional – Jafurah indicative of regional pivot

The share of unconventional gas in global production will increase to more than 30% by 2030. This expected increase in unconventional production is primarily due to a decline in exploration success over the past decade and the lack of developed conventional gas projects, pointing to a reduction in overall conventional gas supply.

The Gulf Cooperation Council (GCC) region has traditionally been an oil and gas production powerhouse. However, in recent years, there has been a decline in large conventional discoveries, spurring countries in the region to explore and develop more unconventional resources.

Saudi Arabia exemplifies this transition as the kingdom aims to eliminate oil from its power production and achieve an electricity generation split of 50% renewables and 50% natural gas by 2030. This shift toward a more diversified energy landscape is supported by the growing demand for gas within the country, forecast to reach 125 billion cm3 annually by the decade's end.

To match burgeoning demand, Saudi Arabia will require new production from non-associated gas fields as well as unconventional gas plays, such as the Jafurah field – the most extensive liquids-rich shale gas play in the Middle East, with estimated lifetime investments exceeding US$100 billion. Saudi Aramco, the driving force behind the Jafurah project, plans to achieve peak shale gas production of 2 billion ft3 per day by 2030.

Rystad Energy estimates that this target of peak production will be met in the second half of the 2030s. By then, the project could account for nearly 15% of Saudi Arabia’s total gas production, providing a significant boost to the nation’s overall gas supply.

Call for capital – Development needed for long-term supplies

Global gas demand will rise toward the middle of the 2030s. However, currently producing and underdeveloped gas fields are expected to peak production in the next couple of years before starting to decline. Even considering all the fields yet to be sanctioned and currently in the discovery lifecycle category, peak production is still far from realisation under ideal scenarios.

Our analysis of global warming scenarios suggests more gas exploration and production is required to meet 1.9 or 2.5° of warming. In every scenario except the 1.6 degrees, additional gas resources are needed to meet demand. Therefore, gas exploration and additional capital investment within prominent gas basins or gas-rich countries are necessary.

Unconventional gas will continue to play a prominent role in the world’s supply mix, estimated to increase to approximately a third by 2030. This expected increase in unconventional production is primarily due to a decline in exploration success over the past decade and the lack of developed conventional gas projects, leading to a drop in the overall conventional gas supply.

Only 32% of conventional gas volumes discovered since 2010 are producing, with more than 50% yet to be approved for development. As a result, countries that rely on conventional sources of gas will have to turn towards unconventional volumes to meet net-zero targets and satisfy global demand if they do not increase their investment in production.
