據(jù)今日石油網(wǎng)2021年5月14日?qǐng)?bào)道，圭亞那-蘇里南盆地被油氣行業(yè)的分析人士視為全球深水勘探的最后一個(gè)重要領(lǐng)域。2015年，世界級(jí)的圭亞那麗莎大油田發(fā)現(xiàn)是當(dāng)時(shí)10年來(lái)最大的海上石油發(fā)現(xiàn)，迄今為止，麗莎大油田發(fā)現(xiàn)在全球深水領(lǐng)域的成功仍是無(wú)與倫比的。

　　在今日石油網(wǎng)日前看到的一份全球未來(lái)油氣勘探的新研究報(bào)告中，韋斯特伍德全球能源集團(tuán)表示，全球油氣勘探領(lǐng)域在今后5年內(nèi)將發(fā)生很多變化。

　　韋斯特伍德說(shuō)，“2015年，石油行業(yè)受到油價(jià)暴跌的影響，結(jié)束了100美元/桶的繁榮時(shí)期。當(dāng)時(shí)很難看出下一個(gè)大的油田將來(lái)自哪里。”韋斯特伍德指出，一個(gè)由多家公司組成歷時(shí)8年鉆取69口探井在晚白堊紀(jì)地層尋找“類似”朱比利遠(yuǎn)景區(qū)的戰(zhàn)役最終仍未能命中這個(gè)遠(yuǎn)景區(qū)。

　　韋斯特伍德說(shuō)：“2015年在圭亞那發(fā)現(xiàn)了世界級(jí)的麗莎大油田，這是自2006年在桑托斯盆地發(fā)現(xiàn)鹽下油氣藏以來(lái)的第一個(gè)重大石油發(fā)現(xiàn)。”“更重要的是，圭亞那擁有良好的財(cái)政條件，麗莎大油田在發(fā)現(xiàn)后的4年半時(shí)間里就投產(chǎn)。”

　　然而，韋斯特伍德表示，圭亞那-蘇里南盆地的成功高度集中，3個(gè)合作伙伴在斯塔布魯克許可區(qū)塊發(fā)現(xiàn)了85%的資源，美國(guó)石油巨頭埃克森美孚公司與其另外兩個(gè)合作伙伴迄今已在該區(qū)塊發(fā)現(xiàn)了超過(guò)90億桶油當(dāng)量的資源。

　　韋斯特伍德表示：“總的來(lái)說(shuō)，自2014年油價(jià)暴跌以來(lái)，人們更關(guān)注周期時(shí)間，勘探公司已將更多資金投向探明盆地和正在成熟和已成熟遠(yuǎn)景區(qū)。”

　　這在2020年尤其明顯，盡管行業(yè)受到石油需求暴跌和價(jià)格觸底的嚴(yán)重打擊，圭亞那-蘇里南盆地的投資仍然強(qiáng)勁。

　　韋斯特伍德認(rèn)為，除非在其他地方有重大發(fā)現(xiàn)，開(kāi)辟其他盆地，否則未來(lái)的熱點(diǎn)地區(qū)可能會(huì)被目前的地區(qū)所主導(dǎo)，比如圭亞那-蘇里南盆地。

　　該咨詢集團(tuán)表示：“晚白堊紀(jì)麗莎遠(yuǎn)景區(qū)是自巴西海上300億桶鹽下碳酸鹽遠(yuǎn)景區(qū)發(fā)現(xiàn)以來(lái)出現(xiàn)的這個(gè)最大的新石油遠(yuǎn)景區(qū)，這個(gè)遠(yuǎn)景區(qū)在2006年發(fā)現(xiàn)了圖皮大油田。”

　　今日石油網(wǎng)了解到，在發(fā)現(xiàn)圖皮大油田和麗莎大油田之間的9年時(shí)間里，全球有超過(guò)250家公司參與了超過(guò)350口的前沿勘探井，其中70%的勘探井目標(biāo)是油氣藏，超過(guò)一半的勘探井試圖開(kāi)發(fā)新的盆地。

　　韋斯特伍德說(shuō)：“從發(fā)現(xiàn)麗莎大油田以來(lái)，在所鉆的159個(gè)前沿遠(yuǎn)景區(qū)中，只有11個(gè)前沿遠(yuǎn)景區(qū)具有潛在商業(yè)價(jià)值。其中包括2015年在MSGBC晚白堊紀(jì)發(fā)現(xiàn)了巨大的Tortue天然氣遠(yuǎn)景區(qū)和2015年在東地中海的碳酸鹽巖中發(fā)現(xiàn)了祖爾大氣田。全球自那以來(lái)迄今還沒(méi)有發(fā)現(xiàn)新的石油遠(yuǎn)景區(qū)。”

　　地球上是否還有數(shù)十億桶的石油儲(chǔ)量有待發(fā)現(xiàn)?石油行業(yè)繼續(xù)尋找這些儲(chǔ)量的難度會(huì)有多大?人們將拭目以待。

　　Liza could be last major frontier oil play discovered in the world – Westwood

　　The Guyana-Suriname basin is viewed by analysts in the oil and gas industry as potentially the last major frontier for deepwater discoveries. The world-class Liza discovery in 2015 was the biggest offshore oil strike made in a decade at the time and remains unparalleled to this day for deepwater success around the world.

　　In a new study seen by OilNOW with focus on future exploration, Westwood Global Energy Group said much can happen in the exploration world in five years.

　　“In 2015 the industry was reeling from the oil price crash that ended the $100/bbl boom period. At the time it was hard to see where the next big oil play was going to come from,” the company said, pointing out that a multi-company 69 well, 8-year campaign chasing frontier Late Cretaceous Jubilee ‘look-alike’ plays had failed to hit pay.

　　“Then along came the Liza discovery in 2015 in acreage in Guyana that opened a potentially ten-billion-barrel oil province, the first since the presalt Santos in 2006,” Westwood said. “What is more, Guyana boasted excellent fiscal terms and Liza was onstream in four and a half years.”

　　The consultancy group said the success in Guyana-Suriname has been highly concentrated, however, with 85% of the discovered resource captured by the three partners in the Stabroek licence where U.S oil major ExxonMobil has so far found over 9 billion barrels of oil equivalent resources.

　　“Overall, since the 2014 oil price crash there has been more of a focus on cycle times and explorers have been allocating more capital to proven basins and maturing and mature plays,” Westwood said.

　　This was particularly evident over the last year where despite the industry being hit severely by plummeting oil demand and prices bottoming out, investments in the Guyana-Suriname basin remained robust.

　　Westwood believes future hotspots are likely to be dominated by those of the present, such as the Guyana-Suriname province, unless significant discoveries are made elsewhere, opening up other basins.

　　“The Upper Cretaceous Liza play is the largest new oil play to emerge since the 30 bnbbl Pre-salt Carbonate play offshore Brazil that emerged with the Tupi discovery in 2006,” the consultancy group said.

　　OilNOW understands that in the nine years between Tupi and Liza, more than 250 companies participated in over 350 frontier exploration wells globally with ~70% of these targeting oil plays and more than half attempting to open new basins.

　　“Since Liza there have been just 11 potentially commercial discoveries from the 159 frontier play wells drilled,” Westwood said. “These include the giant gas plays in the Upper Cretaceous of the MSGBC (Tortue 2015) and the carbonates of the Eastern Mediterranean (Zohr 2015). There have been no new oil plays opened.”

　　Are there more multi-billion-barrel oil plays out there to be found and how hard will the industry continue to search for them?
