据全球石油新闻网2019年的10月28日华盛顿报道，美国恩特普莱斯产品合作伙伴公司（Enterprise Products Partners）的目标是在2020年第三季度前第3次扩建其米德兰至埃科（ME）原油管道系统，使其原油日输送能力增加45万桶，而随后45万桶/天的扩建将允许恩特普莱斯产品合作伙伴公司能够把塞米诺尔管道改造成为天然气液体（NGL）服务。
恩特普莱斯产品合作伙伴公司首席执行官吉姆•蒂格在第三季度财报电话会议上表示，如果得到需求支撑，米德兰至埃科原油管道系统的第4次扩建规模可能升至54万桶/天。
蒂格表示，恩特普莱斯产品合作伙伴公司可能会把米德兰至埃科-2管道(以前称为塞米诺尔管道)重新转换为NGL服务，不过他没有透露预期的时间。
蒂格说：“看看我们的原油系统的数学：恩特普莱斯产品合作伙伴公司能够以最优成本每天运输130万桶原油。”“如果市场需要更多产能，恩特普莱斯产品合作伙伴公司可以在零资本的情况下把产能提升至180万桶/天。”
第三季度，恩特普莱斯产品合作伙伴公司平均每天通过管道输送230万桶原油，比去年同期增加了21%。
今年第三季度，恩特普莱斯产品合作伙伴公司在休斯顿航道和德克萨斯州博蒙特港的原油日出口量跃升至98.7万桶，比去年同期增加了56%。

Enterprise aims for third Midland-to-ECHO oil expansion by Q3 2020
Enterprise Products Partners aims to add 450,000 b/d of capacity to its Midland-to-ECHO crude oil pipeline system by the third quarter of 2020, with a subsequent 450,000 b/d expansion allowing the company to convert the Seminole pipeline back to NGL service.
The fourth expansion of the system could ramp up to 540,000 b/d if demand supports it, CEO Jim Teague said during a third-quarter earnings call.
Teague said Enterprise would likely convert the Midland-to-ECHO 2 pipeline, formerly called the Seminole pipeline, back into NGL service, although he did not share timing expectations.
"Look at the math in our crude oil system: Enterprise can transport at optimum cost 1.3 million b/d," Teague said. "If the market needs more capacity, Enterprise can ramp that capacity to 1.8 million b/d with zero capital."
Enterprise moved an average of 2.3 million b/d of crude through its pipelines in Q3, up 21% from a year earlier.
