据海上能源7月25日报道，墨西哥湾管道运营商威廉姆斯公司已经收购并投入使用16英寸诺夫利特远景区深水采集管道系统。

威廉姆斯公司周一表示，该管道系统由壳牌和中海油建造，从壳牌运营的深度为7400英尺水域处的阿波马托克斯浮式生产系统延伸54英里至位于亚拉巴马州莫比尔以南约60英里的Transco主通道261A连接平台。首个个天然气交付日期是2019年6月22日。

阿波马托克斯是目前在墨西哥湾深水区诺夫莱特地层投产的第一个商业发现。阿波马托克斯也是壳牌在美国墨西哥湾的最大平台。

威廉姆斯称，通过将威廉姆斯公司现有的Transco海上管道连接到壳牌公司和中海油在墨西哥湾东部开发的多产侏罗纪油田，这一管道系统的收购扩大了威廉姆斯管道网络的范围。

威廉姆斯公司总裁兼首席执行官阿兰·阿姆斯特朗表示，我们很高兴能与壳牌和中海油一起参与这次侏罗纪开发活动。

壳牌展示了在墨西哥湾成功大规模开发项目的辉煌历史，这里的早期迹象表明，在这个侏罗纪地层，他们将继续其他新发现。

诺夫莱特深水天然气采集管道系统能够每天收集2.61亿至2.91亿立方英尺(mmcf/d)的天然气，通过主通道261A连接平台处的Transco lateral将3.3万英亩的专用租约区连接到威廉姆斯的移动海湾处理设施。

已完成的项目还包括安装一个备用的海底连接器，用于额外的浮式生产系统容积，以及威廉姆斯公司的移动海湾处理设施进行修改，包括增加118%的段塞处理能力和329%的稳定能力。

威廉姆斯称，诺夫莱特深水天然气收集系统非常适合未来的增长，约有50%的管道的合同容量可用于该地区的未来生产商发现。

Williams’ Gulf of Mexico Norphlet deepwater pipeline enters service

Gulf of Mexico pipeline operator Williams has acquired and placed into service the 16-inch Norphlet play deepwater gathering pipeline system.

The pipeline system constructed by Shell and CNOOC extends 54 miles from the Shell-operated Appomattox Floating Production System in 7,400-feet of water to the Transco Main Pass 261A junction platform, located approximately 60 miles south of Mobile, Alabama. First gas delivery date occurred on June 22, 2019, Williams said on Wednesday.

Appomattox is the first commercial discovery now brought into production in the deep-water Gulf of Mexico Norphlet formation. Appomattox is also Shell’s largest platform in the U.S. Gulf of Mexico.

Williams said that the pipeline system acquisition extends the reach of the Williams pipeline network by connecting Williams’ existing Transco offshore pipeline lateral to the prolific Jurassic play developed by Shell and CNOOC in the eastern Gulf of Mexico.

Alan Armstrong, president and chief executive officer of Williams said: “We are excited to participate in this Jurassic development with Shell and CNOOC.”

“Shell has exhibited a tremendous history of successful large-scale developments across the Gulf of Mexico and early indications here are for that to continue in this Jurassic play with their additional discoveries.”

The Norphlet deepwater gas gathering pipeline system, which is capable of gathering an estimated 261 to 291 million cubic feet per day (MMcf/d) of natural gas, connects more than 33,000 acres of dedicated leases, to Williams’ Mobile Bay processing facility via the Transco lateral at the Main Pass 261A junction platform.

The completed project also included the installation of a spare subsea connector for additional floating production system volumes, as well as modifications to Williams’ Mobile Bay processing facility including a 118% expansion to the slug handling capacity and a 329% increase in stabilizing capacity.

“The Norphlet deepwater gas gathering system is well-positioned for future growth with approximately 50% of the pipeline’s contractual capacity remaining available for future producer discoveries in the area,” Williams said.
