科技论文 Multizone Openhole Gravel Packing with Enhanced Shunt Screens and Zonal Isolation in High-Rate Gas Wells
Reduced well count, handled high temperatures, accessed marginal gas pockets uneconomic for single-zone wells.
OptiPac service mechanical packer
The packer is equipped with field-proven Alternate Path shunt tubes; once the uppermost zone is packed, gravel is diverted through the shunt tubes to the next zone. Additional time and cost savings can be achieved by using these packers with shunted blanks to bypass nonproducing zones and only gravel packing above and below.
The OSMP packer can be fitted with a shunt tube isolation valve, which is closed once gravel packing is complete, preventing any unwanted communication between zones. If water breaks through a producing zone, a seal assembly can be run inside the screen completion to create a secondary isolation. This allows unrestricted flow from other zones without production from the water zone.
The OSMP packer is expanding the operating envelope for multizone openhole gravel packing, enabling wellbore profiles and completion designs that were previously unattainable.
