油藏采收:数字化转型的机遇
Peter Zornio / 艾默生自动化解决方案

随着石油和天然气公司不断适应油价长期较低的新常态,人们对数字化及其推动更好业绩的潜力进行了很多讨论。人们普遍预计工业物联网、机器学习、增强现实和人工智能等数字创新将在未来十年的行业发展中发挥主导作用。但数字化何时才能迎来黄金时段呢?它真的会成为上游企业一直希望的变革推动者,帮助他们追回经济低迷期间损失的利润吗?

为了探讨这个问题,让我们看看生产商最大的收入和利润机会之一——最大限度地提高油藏采收率。

最大限度地恢复。由于 2010 年代初期的市场衰退大幅减缓了新的资本投资,因此重点主要放在优化上:尽可能提高现有油井和油藏的采收率,同时降低生产成本。这种方法通常在两个不同但很大程度上相互依赖的领域内实施,我们称之为“水库循环”和“生产循环”。它们可以而且通常是两个完全离散的组织。特别是对于大型跨国公司而言。
问题就在这里。

油藏环路包括地质学家和岩石物理学家,他们分析地震数据、开发油藏模型并帮助规划钻井活动。由于需要时间和计算能力,油藏模型不会定期根据实际生产数据进行更新。因此,该模型本质上只是对储层真实地质结构的最佳估计,数据中存在显着的方差和不确定性。 

在生产环路中,操作和生产人员执行现场操作的日常任务,努力提高油井性能并降低生产成本。他们决定在哪里应用人工举升、何时安排维护、如何解决活跃井的问题以及确保合规性所需的内容。

这些操作决策是在没有考虑油藏模型的情况下做出的,通常是因为生产人员无法以允许他们在日常事件背景下查看模型数据的方式访问模型数据。相反,由于油藏模型没有根据现场的真实地质数据进行更新,因此井位和轨迹等内容不太准确,并且需要更长的时间来规划。所有这些都会对从油田提取最多产品的能力产生巨大影响。

打破油藏和生产循环之间的隔阂是数字化有可能成为真正的游戏规则改变者的一种方式。

在这种情况下,生产决策将由油藏模型驱动,该模型可以根据现场信息快速更新,而不是根据初始地震数据进行概率预测。地面上的工程师将能够在任何有 WiFi 或蜂窝连接的地方访问模型数据。算法和机器学习会将来自现场的大量信息转化为可以指导操作并识别优化机会的见解。领域专家会将机器学习结果置于适当的背景下,应用“合理性检查”,并将各种应用程序(油藏、可靠性、成本、业务目标)的不同方向和策略协调为正确的行动。

现在就可以做到。这只是对未来的一些不切实际的愿景。实现这一目标所需的工具已经存在,现在就是使用它们的时候了。为什么?首先,油价每桶 50 至 60 美元的新现实迫使该行业专注于现有资产的最大化。与此同时,更多的井正在更短的时间内钻探,页岩的情况就是如此。云计算和更好的工业物联网连接的突破使得连接各种必要的系统成为可能,并提供现场和任何其他需要的油藏数据的集成视图。与新的建模技术相结合,模型可以更快地更新,以便根据尽可能最佳的信息做出生产决策。

诚然,如此大规模地实施整合所涉及的问题并不简单。在正确的背景下共享信息是最大的问题之一。传统上,建立模型的油藏专家和抽油的操作团队只是不说话。这显然必须改变。但当然,总的来说,变革管理本身就是一个问题。为了充分利用正在出现的机遇,组织需要专注于适应新技术的功能。理想情况下,此类项目应作为更大的数字化转型战略的一部分,包括文化变革、工作流程和流程变革以及物联网部署。

利用数字解决方案合并两个历史上独立的油藏和生产循环,将为新油藏和现有油藏迎来最大采收率的新时代大有帮助。技术就在这里。运营商有责任承诺进行必要的变革,以实现这一切。 wo-box_blue.gif

Reservoir recovery: An opportunity for digital transformation
Peter Zornio / Emerson Automation Solutions

As oil and gas companies continue to adapt to the new normal of lower-for-longer oil prices, there’s been a lot of talk about digitization and its potential to drive better performance. Digital innovations like the Industrial IoT, machine learning, augmented reality, and artificial intelligence are widely expected to play leading roles in the industry’s evolution over the next decade. But when will digital be ready for prime time? And will it really be the change agent that upstream players have been hoping for, to help them claw back profits lost during the downturn?

To explore this question, let’s look at one of the biggest revenue and profit opportunities that producers have—maximizing reservoir recovery.

Maximizing recovery. Since the market decline in the early 2010s dramatically slowed new capital investments, the focus has been primarily on optimization: maximizing recovery from existing wells and reservoirs while lowering production costs, wherever and whenever, possible. This approach is often carried out within two different but largely interdependent domains, which we’ll call the “reservoir loop” and the “production loop.” These can be, and often are, two entirely discrete organizations—especially in the case of major multinational companies. And therein lies
the problem.

The reservoir loop includes the geologists and petrophysicists, who analyze seismic data, develop reservoir models, and help plan drilling activities. Because of the time and computational power required, reservoir models aren’t updated with actual production data on a regular basis. As a result, the model is essentially just a best estimation of the reservoirs’ true geologic structure, with significant variances and uncertainties built into the data. 

Over in the production loop, operations and production staff carry out the day-to-day tasks of field operation, working to increase well performance and bring down production costs. They determine where to apply artificial lift, when to schedule maintenance, how to fix problems with active wells, and what’s needed to ensure regulatory compliance.

These operational decisions are made without taking the reservoir model into account, usually because production crews can’t access the model data in a way that allows them to view it in the context of day-to-day events. Conversely, because the reservoir models aren’t updated with real geologic data from the field, things like well placement and trajectory are less accurate and take longer to plan. All of this can have a huge impact on the ability to extract the most product from the field.

Breaking down the silos that separate the reservoir and production loops is one way that digitization has the potential to be a real game-changer.

In this scenario, production decisions would be driven by reservoir models that can be updated quickly with information from the field, instead of probabilistic projections from initial seismic data. Engineers on the surface would be able to access model data anywhere there’s a WiFi or cellular connection. Algorithms and machine learning would boil the flood of information from the field into insight that can guide operations and identify opportunities for optimization. And domain experts would put machine learning outcomes in the appropriate context, apply “sanity checks,” and harmonize the various directions and strategies of various applications (reservoir, reliability, costs, business goals) into the right actions.

It can be done now. This isn’t just some pie-in-the-sky vision of the future. The tools needed to make it happen are available—and the time to use them is now. Why? First, the new reality of $50-to-$60/bbl oil prices has forced the industry to focus on maximizing existing assets. At the same time, more wells are being drilled in shorter time, as is the case with shales. Breakthroughs in cloud computing and better Industrial IoT connectivity have made it possible to link the various necessary systems, and provide integrated views of reservoir data in the field and anywhere else they’re needed. Combined with new modeling technology, models can be updated much faster, so that production decisions are made with the best possible information.

To be sure, the problems involved with implementing integration on such a wide scale aren’t simple ones. Sharing information in the right context is one of the biggest issues. Traditionally, the reservoir experts building the models and the operations team pumping the oil just don’t talk much. This obviously has to change. But of course, change management, in general, is a problem of its own. To take full advantage of the opportunities afoot, organizations are going to need to focus on adapting to the capabilities of the new technology. Ideally, this kind of project would be approached as part of a larger digital transformation strategy, comprised of cultural change, workflow and process changes, and IoT deployment.

Leveraging digital solutions to merge the two historically separate reservoir and production loops will go a long way toward ushering in a new era of maximum recovery for both new and existing reservoirs. The technology is here. It’s up to the operators to commit to carrying out the changes needed to make it all happen. wo-box_blue.gif
