埃克森美孚的圭亚那发现得益于新技术应用

埃克森美孚公司首席执行官达伦·伍兹日前在公司2020年股东大会上表示，这些新技术的使用使得圭亚那斯塔布鲁克区块的钻井成功率大大高于行业平均水平。

伍兹说：“一个最近的例子是专有的全波地震反演技术，它有助于识别油气藏。去年，这个技术使公司获得了全球10大勘探发现中的4项，以及全球6大石油发现中的5项。”伍兹说的5大石油发现分别是Tilapia、Haimara、Yellowtail、Tripletail和Mako石油发现。

伍兹表示新技术把公司在斯塔布鲁克区块内的钻井成功率提高到了89%，远高于行业的平均水平。伍兹补充说：“估计圭亚那海上可采资源量已经增加到80多亿桶，这是我们两年前估计的可采资源量的两倍半。”

伍兹说，由于埃克森美孚公司能够在圭亚那快速发现油田，并在相对较短的时间内进行开发，这使得该公司去年12月投产丽莎大油田距离首次世界级的发现还不到5年。到目前为止，圭亚那已从石油销售和矿区使用费中获得了近6000万美元的收入。

差不多50年前，埃克森美孚公司率先开发了一种名为三维地震成像的技术，这种技术利用声波来形成地质建造的三维图像。这些图像已经成为了解地下地质和寻找石油和天然气田的行业标准。全波场反演技术是该公司勘探和开发工作的一个组成部分，也是其被称为EMprise的一组地震能力的一个标志性部分。

在过去，由于地震波的高度复杂性和数据的绝对数量，石油行业只能利用在三维地震测量中记录的部分数据。现在，FWI已经为该公司提供了更好的利用所有地震测量数据的能力，以生成地下的高分辨力的图像。

Why is Exxon finding oil faster in Guyana than companies anywhere else in the world?

Several high impact discoveries which have been made offshore Guyana by US oil major ExxonMobil are a direct result of the company’s research and development of new technologies which have provided geoscientists with unparalleled insights into subsurface geologic structures and the physical characteristics of rocks.

Speaking at the company’s 2020 Annual Meeting of Shareholders on Wednesday, CEO Darren Woods said the use of these technologies has helped push the drilling success rate at Stabroek Block well above the industry average.

“A recent example is our proprietary full wave seismic inversion technology which helps identify hydrocarbon reservoirs. Last year, this enabled us to have four of the top ten exploration discoveries in the world and five out of the six largest oil discoveries,” he said, referring to the Tilapia, Haimara, Yellowtail, Tripletail and Mako oil strikes.

Woods said the technology increased the company’s drilling success rate at Stabroek Block “to 89 percent, well above the industry average,” adding that, “The estimated recoverable resource offshore Guyana has now increased to more than 8 billion barrels, about two and a half times what we estimated just two years ago.”

The company’s ability to make rapid discoveries in Guyana and move to development in a relatively short time-frame has resulted in oil production starting at the Liza Field last December, less than five years after the first world-class discovery. This has seen Guyana so far receiving close to US$60 million from oil sales and royalty.

Nearly 50 years ago, ExxonMobil pioneered a technology called 3-D seismic imaging, which uses sound waves to form three-dimensional images of geologic formations. These images have become the industry standard for understanding subsurface geology and finding oil and gas deposits. Full Wavefield Inversion (FWI) is an integral part of the company’s exploration and development efforts and a signature part of its suite of seismic capabilities known as EMprise.

In the past, the industry could only utilize a portion of the data recorded in 3-D seismic surveys due to the high complexity of the seismic waves and the sheer quantity of data. Now, FWI has provided ExxonMobil with the ability to better leverage all of the data from a seismic survey to produce high-definition images of the subsurface.
