The selected completion design required setting two packers independently. After the lower production packer was set above the screens, drilling mud would be circulated out through a sliding sleeve above the packer and replaced with completion brine. Subsequently, a second packer would be set above the sliding sleeve to isolate it. Delaying setting of the upper packer was critical to successful mud removal. 然而, most of the operator's suppliers could not provide packers that would allow this customized setting sequence; their packers would set simultaneously and the completion procedure would not work.
BluePack Max RH high-pressure retrievable hydraulic-set production packers are built on a customizable platform that enables modification of the setting pressure. 斯伦贝谢推荐使用该封隔器 as the upper packer and an MRP conventional packer below. Adjusting the BluePack Max RH packer's setting pressure above that of the lower packer enabled the operator to implement its time-saving completion 选择技术.
The upper packer was equipped with a hydrostatic setting trigger (HST). Applying enough hydrostatic pressure to the well to exceed the HST's burst disk rating initiated packer setting, eliminating the need to run a plugging device below the packer and saving even more time. 除了, the HST's antipreset feature prevents premature packer setting and enables faster run-in speeds.
Four wells were completed using the one-trip method. 平均完成时间仅为4小时.5 days compared with 15 to 17 days in the past, saving the operator approximately USD 2 million per well. BluePack Max RH packers are now the production packers of choice in this deepwater oil field.
