俄气石油使用数字技术提高难采储量采收率

据俄罗斯油气网5月22日圣彼得堡报道,俄罗斯天然气股份石油公司(俄气石油/Gazprom Neft)日前已经成功地在公司资产上部署了“网络压裂2.0”(Cyber-Fracking 2.0)模拟器。该模拟器模拟了在水力压裂下产生裂缝的过程,并确定了进行地质作业的最佳选项。

当与俄气石油的其它数字工具一起使用时,这项技术可使低渗透性地层的石油生产效率提高5%。从长远来看,部署这一数字工具的经济效益约为48亿卢布。

Cyber-Fracking 2.0项目成功地通过了针对来自非俄罗斯公司的类似模拟器的基准测试,这个系统的算法显示出比市场上现有的竞争对手更好的结果,具体地说,显示了俄罗斯技术在模拟地下水力压裂作业时重现裂缝特征的准确度提高了10-20%。

Cyber-Fracking 2.0项目的另一个优势是它的高速度——对单井的运算只需不到3分钟。

该模拟器首次在俄气石油Khantos油田的一组直井和水平井中进行了模拟试验,为修正传统的压裂方法提供了工程解决方案。Cyber-Fracking 2.0项目允许专家为极端条件下的水力压裂作业提供另一种选择。

在通过模拟器开发的模型基础上,压裂液被注入到几公里深的地层中。来自实际压裂作业的结果——如压力传感器读数——与预测一致。

俄气石油计划今年在6家子公司的油田上推出这一新的数字项目,在不同地质条件下的50口油井上使用该模拟器。

俄气石油负责勘探和生产的副首席执行官瓦迪姆·雅克夫列夫说:“在低油价的新现实下,项目可行性问题特别重要。数字技术正在帮助我们实现业务流程的现代化,并快速优化决策。除此之外,每一个能够提升我们业务领域的项目——哪怕只是提升几个百分点——如果与其他数字产品协同使用,最终都能带来可观的利润,并带来新的机遇。正是因为这个原因,我们和我们的合作伙伴正在开发我们自己的It产品,这些产品可以提高石油和天然气行业的整体效率。”

Gazprom Neft succeeds in using digital technologies to enhance recovery of “hard-to-recover” reserves

Neftegaz.RU. Gazprom Neft has succeeded in deploying its “Cyber-Fracking 2.0” simulator at company assets. The “Cyber-Fracking 2.0” simulator models the processes involved in creating fissures under hydraulic fracturing (fracking), and determines the best options for undertaking geological operations.

When used together with other Gazprom Neft digital tools this technology can deliver a 5% efficiency gain in oil production at low-permeability formations. The economic benefit of deploying this digital tool is estimated at around RUB 4.8 billion in additional income, long term.

The Cyber-Fracking 2.0 programme successfully passed benchmark testing against similar simulators from non-Russian companies, with the system’s algorithms showing better outcomes than existing competitors>A further advantage of the Cyber-Fracking 2.0 programme is its high speed - taking less than 3 minutes to make calculations>The simulator was used for the 1st time at a group of Gazpromneft-Khantos vertical and horizontal wells to produce engineering solutions with a view to revising traditional approaches to fracking strata. The Cyber-Fracking 2.0 programme allowed specialists to produce an alternative option for operations under extreme conditions.

based>Gazprom Neft plans to roll-out this new digital programme at fields belonging to 6 subsidiaries throughout 2020, with the simulator being sued at 50 wells, under various geological conditions.

“Under the new realities of low oil prices, the question of project viability is particularly important. Digital technologies are helping us modernise business processes and optimise decision making, fast. Added to which, every programme that improves an area of our business - even by just a few percent - can, when used in synergy with other digital products, ultimately deliver a significant profit, opening up new opportunities. It is for precisely that reason that we, together with our partners, are developing our own IT products - products that could improve efficiency for the oil and gas industry, as a whole”, said Vadim Yakovlev, Deputy CEO for Exploration and Production, Gazprom Neft.
