据3月13日Oil Now报道，自从2015年美国石油巨头埃克森美孚首次发现世界级的石油资源以来，新石油生产国圭亚那一直是全球发现资源最多的国家。该公司在高产的Stabroek区块钻了21口探井，有18口获得了石油发现，保持了80%以上的成功率，这在油气行业是前所未有的。
Rystad Energy数据显示，在过去六年中，该国平均每口勘探井(wildcat and appraisal)的石油发现量达3亿桶石油当量。
Rystad Energy上游团队分析师Santosh Kumar表示:“2021年计划钻探约16口探井，其中一些位于风险较高的地区。”
埃克森美孚上游业务高级副总裁尼尔•查普曼(Neil Chapman)表示，该公司迄今在圭亚那近海发现的90亿桶石油资源只是冰山一角。他指出:“该项目仍处于早期阶段，但我们仍然感到非常鼓舞，我们估计该盆地的资源潜力将是我们已经发现的两倍以上。”
今年，该石油巨头将在圭亚那近海进行积极的勘探和评估钻井计划，目标是Stabroek和Canje区块。就在本周，该公司使用Stena Carron钻井船在这两个区块连续开井，并使用最近抵达的Stena DrillMAX钻机进行评估钻井。
Rystad能源公司海上钻井跟踪系统显示，目前有三艘钻井船在greater Liza地区进行开发钻井活动最近到达的Stena DrillMAX已经开始了Longtail-2评价井的钻探活动，而Stena Carron钻井船最近完成了bullet - wood-1的钻探，现在正在Canje区块开钻jabilo -1探井。
埃克森美孚圭亚那公司总裁阿利斯泰尔·劳特利奇（Alistair Routledge）表示:“我们预计明年将钻探十多口探井和评勘井，其中几口将在Stabroek区块东南部的核心区域。”
劳特利奇表示，该公司还打算瞄准这些发现以西的油井。到目前为止，Ranger井是该公司在该区块西北部钻探的最远油井，也是Stabroek有史以来钻探的最深油井。

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.
