探索的新内容:“它”能赚钱吗?

答案:好吧,如果税收拿走了所有“好处”,那就不会了。美国新的反通胀立法似乎是各国政府愚蠢行为的受害者。

答案:好吧,如果税收拿走了所有“好处”,那就不会了。美国新的反通胀立法似乎是各国政府愚蠢行为的受害者。我很清楚,当世界要求限制、征税或停止勘探时,它就走上了错误的道路。停止对传统能源(即过去 160 年来我们的机器所共有的能源)的探索与停止种植粮食是一样的。事实上,其中之一会直接导致另一个。对于那些被迫走上这条路的人来说,这不是一个好的结局。

然而,监管者或者他们的老板真的那么天真吗?当我根据研究合同在能源部工作时,我首先想到前总统奥巴马任命的领导人都是天真的业余爱好者。几年后,我不再相信他们天真了。那么为什么要制定一项故意破坏性的政策呢?不需要太多的猜测就能回答。然而,我们可能在杂草中发现了一朵花。世界石油网 7 月 22 日发表的一篇题​​为“随着工业拥抱可再生能源,全球石油地图正在重新绘制”的帖子称,“想要减少碳足迹的石油巨头将不得不将其活动转移到钻井平台可以作业的能源盆地”。一份报告指出,由可再生能源提供动力,并且有足够的碳封存空间。”  

我微笑。政府引导的油盆绿色钻探有利于CO 2注入——真的吗?嗯。不停!停止!请不要把我扔进那片荆棘丛里!这可能是我们很长一段时间以来听到的最好的消息。同样好的计划是确定废弃的孤儿气井,这些气井也可能有资格作为绿色封存的候选者。然而,过多地强调绿色可能会在你的边境附近招来一支军队。对吧,德国?经过 20 年的绿色政策,萨克森 Uniper 的电力成本与 2002 年的水平相比是多少?顺便说一句,如果海平面上升将成为一个问题,那么为什么集体主义者想要黑海附近的索洛维耶夫海滨财产呢?只是问一下”。  

今年夏天,世界海洋组织和专业协会的每日通知一直在宣扬在地球上化石能源匮乏的国家附近进行新的勘探承诺。这里没有足够的空间来列出它们。令我惊讶的是南部非洲之角周围的计划和发现。我不记得有谁描述过南非附近石油形成和迁移的地理有利条件,除了 SEG/SPE/AAPG 大会后墙小摊位上的人们。新的数据总是带来新的曙光。  

蓝色巨人预测未来几年将扩大勘探规模。勘探支出正在增加,据报道比去年增加了约 20%。嗯,去年的情况很糟糕,油价约为 100 美元,我们能期待什么?尽管如此,我每桶 14 美元的运营成本并没有吸引任何人重新完井或进行更多钻探,因为未来监管的不确定性,而不是价格差异。好吧,每个人都想要大量的储备。但大风险需要大资金。这不会改变。正在发生的变化是,作为早期钻井决策的一部分,人们越来越重视油藏知识,这种变化已经持续了一段时间。  

科学:我们知道的越多,我们知道我们不知道的就越多。在科学和商业领域,对油藏的了解始终处于生产开发风险分析的首位。“它”会产生多少以及多长时间的简单问题,已经演变为母岩的流体动力学特征是什么,与流体发生什么相互作用,以及我们是否可以从地表间接测量这些参数中的任何一个或钻孔。当然,几十年来,半校准钻孔工具和声学推断的类似物为我们提供了更好的评估方法。然而,没有一个是重复的,即使在实验室里也没有一个是 100% 的。 

目前的技术论文试图将我们推向现实的 80% 答案。(今天,即使使用流动的碳氢化合物,所有技术的回收率也都约为 60%。迄今为止,即使使用物理水平方法,也没有一个技术能够获得比约 8-13% 更好的回收率。) 8 月 29 日,在“Mage”22 上,SEG 和 AAPG 在休斯敦举行的新年度会议(图 1)展示了我们行业目前正在进行的广泛油藏讨论的示例:

What’s New in Exploration: Does “it” make money?

Answer: well, not if taxes take all “its” benefits. The new Anti-Inflation legislation in the U.S. appears to be a victim of pandemic stupidity among governments.

Answer: well, not if taxes take all “its” benefits.  The new Anti-Inflation legislation in the U.S. appears to be a victim of pandemic stupidity among governments. It is clear to me that the world is on the wrong course when it demands to limit, tax or stop exploration. Stopping exploration for traditional energy (that is, energy common to our machines for the last 160 years) is the same as saying to stop growing food. In fact, one will directly lead to the other. It’s not a good ending for those who are forced to follow that path.

However, are the regulators or their bosses really that naïve? When I worked for DOE under a research contract, I first thought that former President Obama’s installed leaders were naïve amateurs. After a couple of years, I no longer believed they were naïve. Why then create a deliberately destructive policy? One does not need much conjecture to answer. However, we may have found a flower among the weeds. A World Oil web post, July 22, titled “Global Oil Map Being Redrawn as Industry Embraces Renewables,” said, “Oil majors that want to reduce their carbon footprint will have to shift their activities to energy basins where drilling rigs can be powered by renewables and which have ample space for carbon sequestration, a report indicates.”  

I smile. Government-induced green drilling in oil basins favorable to CO2 injection— really?  Um. No, stop! Stop! Please don’t throw me in that briar patch! This may be the best news we have heard in a long time. Also good are plans to identify abandoned orphan gas wells that may be eligible, too, as candidates for green sequestration. However, too much green emphasis can invite an army next to your border. Right, Germany? After 20 years of go-green policies, what is the cost of Saxony Uniper’s electricity compared to 2002 levels? By the way—if sea level rising is going to be a problem, then why do collectivists want seashore Soloviev property near Black sea? Just askin’.  

Daily notices this summer from WO and professional societies have been trumpeting new exploration commitments near fossil energy-starving countries around this planet. There is not enough space here to list them all. Surprising to me are plans and discoveries around the southern African Horn. I cannot remember anyone describing geo-favorable conditions for oil formation and migration near South Africa, except for the people in tiny booths along the back wall at SEG/SPE/AAPG conventions. New data alway brings new light.  

Big Blue predicts expansion of exploration for the next several years. Exploration spending is gaining, reportedly up about 20% from last year. Well, last year was terrible, and at ~$100 oil, what did we expect? Still, my operating cost of $14/bbl is attracting no one for recompletions or more drilling, because of uncertainty in future regulation, not price disparity. Ok, everyone also wants big reserves. But big risk takes big money. That will not change. What is changing, and has been for a while, is the increased emphasis on reservoir knowledge, as part of early drilling decisions.  

Science: The more we know, the more we know we don’t know. Reservoir understanding has always been at the top of risk analysis, in both science and business, for production development. Simple questions of how much, and how long “it” will produce, have evolved to what the hydrodynamic characteristics of the parent rock are, what interactions are occurring with fluids, and if we can measure any of those parameters indirectly from the surface or borehole. Certainly, over the decades, analogs of semi-calibrated borehole tools and acoustic inferences have given us greater evaluation methods. However, none—I repeat, none—are 100% even in the laboratory. 

Current technical papers attempt to push us toward a realistic 80% answer. (Today, all tech is about 60%, even with flowing hydrocarbons. None, to date, have been able to get better than about 8-13% recovery, even using physical horizontal methods.)  A couple of Monday’s technical presentations on Aug. 29 at “Image ‘22,” the SEG and AAPG new annual meeting (Fig. 1) in Houston, have shown examples of the extensive reservoir discussion going on right now in our industry:  

“Using multidimensional scaling to estimate the impact of shale volume, fault seal, and fluid migration methods on 3D petroleum saturation, Norwegian Viking Graben,” Anatoly Aseev, Tapan Mukerji and Allegra Hosford Scheirer, Stanford University (INT. AUD.: 4). Speaker: Anatoly Aseev. 

“The competition of oil and gas for trap space and seal capacity,” Martin Neumaier, ArianeLogix; Jan de Jager, JdJ Geological Consultancy; and Ben Kurtenbach, ArianeLogiX (INT. AUD.: 4) Speaker: Jan de Jager. 

STEM education has never been more important to our future, as our numbers of experienced explorers continue to decline. Technical program abstracts will be available from either organization.
