據3月13日Oil Now報道，自從2015年美國石油巨頭埃克森美孚首次發現世界級的石油資源以來，新石油生產國圭亞那一直是全球發現資源最多的國家。該公司在高產的Stabroek區塊鉆了21口探井，有18口獲得了石油發現，保持了80%以上的成功率，這在油氣行業是前所未有的。

Rystad Energy數據顯示，在過去六年中，該國平均每口勘探井(wildcat and appraisal)的石油發現量達3億桶石油當量。

Rystad Energy上游團隊分析師Santosh Kumar表示:“2021年計劃鉆探約16口探井，其中一些位于風險較高的地區。”

埃克森美孚上游業務高級副總裁尼爾?查普曼(Neil Chapman)表示，該公司迄今在圭亞那近海發現的90億桶石油資源只是冰山一角。他指出:“該項目仍處于早期階段，但我們仍然感到非常鼓舞，我們估計該盆地的資源潛力將是我們已經發現的兩倍以上。”

今年，該石油巨頭將在圭亞那近海進行積極的勘探和評估鉆井計劃，目標是Stabroek和Canje區塊。就在本周，該公司使用Stena Carron鉆井船在這兩個區塊連續開井，并使用最近抵達的Stena DrillMAX鉆機進行評估鉆井。

Rystad能源公司海上鉆井跟蹤系統顯示，目前有三艘鉆井船在greater Liza地區進行開發鉆井活動最近到達的Stena DrillMAX已經開始了Longtail-2評價井的鉆探活動，而Stena Carron鉆井船最近完成了bullet - wood-1的鉆探，現在正在Canje區塊開鉆jabilo -1探井。

埃克森美孚圭亞那公司總裁阿利斯泰爾·勞特利奇（Alistair Routledge）表示:“我們預計明年將鉆探十多口探井和評勘井，其中幾口將在Stabroek區塊東南部的核心區域。”

勞特利奇表示，該公司還打算瞄準這些發現以西的油井。到目前為止，Ranger井是該公司在該區塊西北部鉆探的最遠油井，也是Stabroek有史以來鉆探的最深油井。

Average size of each Guyana oil discovery is 300 million barrels

New oil producer Guyana has been at the top of the global list for discovered resources since U.S oil major ExxonMobil made its first world class discovery in 2015. The company has made a total of 18 discoveries out of 21 exploration wells drilled at the prolific Stabroek block, maintaining an above 80 percent success rate which is unprecedented in the oil and gas industry.

“Rystad Energy data suggests that close to 300 million barrels of oil equivalent has been discovered on average for each exploration well (wildcat and appraisal) drilled in the country over the past six years,” the Norway-based consultancy group said in a new report published Friday.

“With around 16 exploration wells planned, including some in riskier frontier regions, 2021 holds a lot of promise,” says Santosh Kumar, analyst with Rystad Energy’s upstream team.

ExxonMobil Senior Vice President of Upstream, Neil Chapman, told investors last week that the 9 billion barrels of oil equivalent resources the company has discovered so far offshore Guyana is only the tip of the iceberg.

“It’s still early days in the programme but we continue to be very encouraged, and we estimate the resource potential of the basin to be more than double what we’ve already discovered,” he pointed out.

The oil major will be pursuing an aggressive exploration and appraisal drilling programme offshore Guyana this year with multiple prospects targeting the Stabroek and Canje blocks. Just this week the company spudded wells back-to-back in these two blocks using the Stena Carron drill ship, and is conducting appraisal drilling in the Longtail area utilizing the recently arrived Stena DrillMAX rig.

“The Rystad Energy Offshore Rig tracker shows that three drillships are currently located in the greater Liza area performing development drilling activity. The recently arrived Stena DrillMAX already initiated drilling activities on the Longtail-2 appraisal well, while the Stena Carron drillship, which recently concluded drilling Bulletwood-1, has now spud the Jabillo-1 exploration well in the Canje block,” Rystad Energy said.

“We expect to drill more than a dozen exploration and appraisal wells over the next year and several of those would be out with that core area in the southeast of the Stabroek block,” ExxonMobil Guyana President, Alistair Routledge recently told OilNOW.

The southeastern area of the 6.6 million acres Stabroek block is where the bulk of the 18 discoveries have so far been made. Routledge said the company also intends to target wells west of these discoveries. So far, the Ranger well is the farthest the company has drilled in the northwest section of the block and is also the deepest well ever to be drilled at Stabroek.
