据油价网2020年8月17日报道，对位于圭亚那海上的凯厄图尔（Kaieteur）区块进行的一项研究结果显示，包括时下正在进行勘探钻井作业的Tanager-1井在内的9个远景构造估计拥有21亿桶石油资源。
《史丹纳卡隆号》钻井船在一周前抵达Tanager-1井钻井现场，预计将在90天内获得这个远景构造的钻探结果。
荷兰威尔联合公司（NSAI）编辑的一份报告显示，Tanager-1井是一个多层油藏的远景构造（麦斯里希特阶到土仑阶储层层段），这个远景构造“具有‘最佳估计’的2.562亿桶无风险的总远景石油储量（低到高估计资源量为1.356亿桶到4.516亿桶)，具有72%的地质成功总概率。”
此外，NSAI的报告显示，凯厄图尔区块南部9个远景构造的‘最佳估计’无风险总资源量为21亿桶石油。从低到高的总估计资源量为6.94桶亿桶至58.5亿桶。
凯厄图尔区块位于圭亚那海岸以外约155英里(约250公里)的海域，面积大约330万英亩，相当于墨西哥湾580多个深水区块的面积。
值得注意的是，凯厄图尔区块与斯塔布鲁克区块位于同一地质盆地内，目前已发现的可采储量超过了80亿桶油当量。
凯厄图尔区块目前由埃克森美孚公司(35%)、Cataleya能源公司(25%)、Ratio 石油公司 (25%)和赫斯公司(15%)共同运营。

9 prospects at Kaieteur Block hold an estimated 2.1 billion barrels of oil
A study conducted The Stena Carron drillship arrived at the Tanager-1 well site a week ago and results from that prospect is expected within a 90-day period.
According to a report compiled by Netherland, Sewell and Associates Inc. (NSAI), the Tanager-1 well is a stacked reservoir prospect (Maastrichtian to Turonian reservoir intervals) “with a ‘best estimate’ unrisked gross (100%) prospective oil resource of 256.2 MMBBLs to the prospect (Low to High Estimates 135.6 MMBBLs to 451.6 MMBBLs), with an aggregate probability of geologic success of 72%.”
Additionally, the NSAI report indicates that the aggregate ‘best estimate’ gross unrisked prospective resources for 9 prospects in the southern part of the Kaieteur Block is 2.1 billion barrels of oil. The aggregate low to high estimates 694 million barrels to 5.85 billion barrels.
The Kaieteur block is located approximately 155 miles (approximately 250 kilometers) offshore the coast of Guyana and is approximately 3.3 million acres, which is equivalent in size to more than 580 deepwater blocks in the Gulf of Mexico.
Significantly, the Kaieteur Block lies in the same geological basin as the Stabroek Block, where total recoverable resources of more than 8 billion barrels of oil equivalent have been discovered to date.
The Kaieteur Block is currently operated by ExxonMobil (35%), with Cataleya Energy Ltd. (25%), Ratio Petroleum (25%) and Hess Corporation (15%) as partners.
