据9月1日Oil Now报道，斯塔布鲁克（Stabroek）区块位于圭亚那近海，占地660万英亩，仍有多个勘探项目良好前景。尽管美国石油巨头和合资企业赫斯公司(Hess)和中海油(CNOOC)已经发现了22个具有商业价值的油田，储量现已超过90亿桶，但埃克森美孚运营许可证的大片区域尚未勘探。
Rystad Energy上游研究和分析副总裁Palzor Shenga表示，圭亚那仍然是埃克森美孚的关键业务区域，未来也将如此，因为阶段性的近海开发将继续提高已探明油田的产量。
分析师表示，现有勘探包括2018年1月宣布的Ranger发现，都集中在东部地区，该区块的西部地区尚未开始勘探钻井。Rystad估计Ranger可能含有3.46亿桶石油。
Ranger-1井是在该区块一个新的区域钻探的，遇到了大约230英尺(70米)的高质量含油碳酸盐岩储层。与该区块东部砂岩储层的其他发现相比，Ranger位于碳酸盐岩储层中，孔隙更大。

Rystad Energy says ‘numerous exploration prospects’ remain at giant Stabroek Block
The prolific Stabroek Block offshore Guyana, covering an area of 6.6 million acres, still has multiple exploration prospects remaining with large swathes of the ExxonMobil-operated license still unexplored. This is despite the U.S. oil major and co-venturers Hess and CNOOC already making 22 commercial discoveries with volumes now exceeding 9 billion barrels of oil equivalent resources.
Palzor Shenga, Vice President for Upstream Research and Analysis at Rystad Energy said Guyana remains a key operational area for Exxon and will continue to be so in the future as the phased offshore developments continue to enhance production from already discovered fields.
“The majority of the block still remains unexplored,” Shenga said in a comment to OilNOW. “It’s align="justify"> The analyst said the western part of the block is yet to begin its exploration drilling, referencing an area including and beyond the Ranger discovery which was announced in January 2018.
Rystad estimates Ranger could contain 346 million barrels of oil
The Ranger-1 well was drilled in a new area, encountering approximately 230 feet (70 meters) of high-quality, oil-bearing carbonate reservoir. Ranger is located in a carbonate play which is more porous when compared to the other discoveries made in sandstone reservoirs in the eastern portion of the block.
