埃克森美孚公司首席執行官達倫·伍茲日前在公司2020年股東大會上表示，這些新技術的使用使得圭亞那斯塔布魯克區塊的鉆井成功率大大高于行業平均水平。

伍茲說：“一個最近的例子是專有的全波地震反演技術，它有助于識別油氣藏。去年，這個技術使公司獲得了全球10大勘探發現中的4項，以及全球6大石油發現中的5項。”伍茲說的5大石油發現分別是Tilapia、Haimara、Yellowtail、Tripletail和Mako石油發現。

伍茲表示新技術把公司在斯塔布魯克區塊內的鉆井成功率提高到了89%，遠高于行業的平均水平。伍茲補充說：“估計圭亞那海上可采資源量已經增加到80多億桶，這是我們兩年前估計的可采資源量的兩倍半。”

伍茲說，由于埃克森美孚公司能夠在圭亞那快速發現油田，并在相對較短的時間內進行開發，這使得該公司去年12月投產麗莎大油田距離首次世界級的發現還不到5年。到目前為止，圭亞那已從石油銷售和礦區使用費中獲得了近6000萬美元的收入。

差不多50年前，埃克森美孚公司率先開發了一種名為三維地震成像的技術，這種技術利用聲波來形成地質建造的三維圖像。這些圖像已經成為了解地下地質和尋找石油和天然氣田的行業標準。全波場反演技術是該公司勘探和開發工作的一個組成部分，也是其被稱為EMprise的一組地震能力的一個標志性部分。

在過去，由于地震波的高度復雜性和數據的絕對數量，石油行業只能利用在三維地震測量中記錄的部分數據。現在，FWI已經為該公司提供了更好的利用所有地震測量數據的能力，以生成地下的高分辨力的圖像。

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.
