石油设备网讯 据普氏能源资讯休斯顿5月10日消息 根据墨西哥国家碳氢化合物委员会批准的一项勘探计划，雪佛龙计划于2021年在墨西哥钻探首个深水油井。
该委员会周四在一次网络直播会议上表示，这家美国公司在其昆卡萨利纳盆地023区块拥有9个勘探目标，该区块是在2018年墨西哥2.4轮招标中中标的。
“这个超深水区域似乎很有前景。然而，它从未经过测试。”CNH的勘探负责人Faustino Monroy表示。
墨西哥国有石油公司Pemex和日本Inpex是雪佛龙在该区块的合作伙伴。
这是CNH第一次批准深水勘探计划，深水2.4轮共批准了19个区块。这一轮的赢家包括壳牌、马来西亚国家石油公司、埃尼集团(和卡塔尔石油公司。
CNH表示，如果第2.4轮中标的19个区块成功开发，到2033年其最高产量将达到150万桶/天。
基根据目前有限的3D地震分析，雪佛龙的最佳勘探前景是超深水Colel Cab目标，该目标在渐新世、上白垩纪和侏罗纪地层中有三个潜在的油层。
雪佛龙将完成其2700平方公里范围内的地震数据采集。处理完这些数据后，该公司将能够更好地对其勘探目标组合进行排名。
Colel Cab仅在白垩统上部地层(深度为5000米)就拥有2.89亿桶油当量的预期资源。
雪佛龙公司将钻探Colel Cab的上侏罗纪地层，深度为6100米。CNH表示，由于盐层的存在，有关其潜力的现有数据有限。

Chevron to drill a wildcat in Mexico's Cuenca Salina Basin in 2021
Chevron aims to drill its first deepwater well in Mexico in 2021, based on an exploration plan approved by the country's National Hydrocarbon Commission.
The US company has nine exploration targets in its Cuenca Salina Basin 023 block, awarded in Mexico's auction Round 2.4 in 2018, the commission, known as CNH, said Thursday in a webcast session.
"This ultra-deepwater region seems highly prospective. However, it has never been tested," said Faustino Monroy, CNH's head of exploration.
Mexico's state-owned oil company Pemex and Japan's Inpex are Chevron's partners in the block.
This is CNH's first approval of a deepwater exploration plan from the 19 blocks awarded at deepwater Round 2.4. Among winners of this round include Shell, Petronas, ENI and Qatar Petroleum.
CNH said if the 19 blocks awarded in Round 2.4 are successfully developed, their peak production will be 1.5 million b/d by 2033.
based on the limited 3D seismic currently analyzed, Chevron's best prospect is the ultra-deepwater Colel Cab target, which has three potential pay zones in the Oligocene, and Upper Cretaceous and Jurassic Layers, CNH said.
Chevron will complete seismic data acquisition across its 2,700-sq.-km block by the end of the year. once this data is processed, the company will be able to rank its portfolio of exploration targets better.
Colel Cab alone has 289 million boe of prospective resources at the Upper Cretacious horizon, which is at a depth of 5,000 meters.
Chevron will drill Colel Cab's Upper Jurassic horizon at 6,100 meters deep to test this horizon. Available data on its potential is limited due to the presence of salt formations, CNH said.
