Alternate Path Sand Screens | Gravel Pack - SLB
Alternate Path systems use shunt tubes and nozzles to create an alternate flow path that allows slurry to bypass bridges and fill in voids that can occur when gravel and frac packing. Options are available for both cased hole and openhole wells. System …
Gravel-Pack Systems - Weatherford International
Part of our WFXØ VØ-rated gravel-pack system, the TerraForm ® SZE openhole packer features built-in shunt-tube technology that provides a continuous flow path to sequentially transport slurry to each gravel-pack zone.
OptiPac Openhole Alternate Path Gravel Packing | SLB
OptiPac openhole Alternate Path gravel-pack service uses shunt-tube technology to ensure maximum gravel-pack efficiency, regardless of conditions such as low fracture gradients, reactive shales, thief zones, washouts, and filtercake plugging that would otherwise result in bridging and incomplete packs. Insufficient packing can lead to erosion ...
OptiPac XL Extended-Length Alternate Path Gravel-Pack Screen
Building on the field-proven success of the OptiPac openhole Alternate Path gravel-pack service, the OptiPac XL screen extends your options into longer, hotter, deeper, multizone, and more complex wells with high-pressure shunt tubes and a high-strength gravel-pack manifold.
A Critical Review of Shunt Tube Deployed Open Hole Gravel Pack ...
2022年9月26日 · Shunt tube deployed Open Hole Gravel Pack (OHGP) completions have been installed in the industry for about 25 years and have become widely recognized as a very reliable sand control completion technique. Some of these shunt tube gravel pack operations, are pumped with no positive surface treating pressure for a long duration of the packing ...
Weatherford’s shunt-tube technology (STT) shunted screen system is designed to allow slurry to bypass sections that have bridged prematurely during gravel-pack or frac-pack operations. With multiple apertures located on the tubes in each screen, the slurry flows to all sections of the wellbore, ensuring a complete annular pack is achieved.
A rugged, flexible technology for cased hole gravel-pack and frac-pack operations, using shunt tubes and nozzles to provide alternate slurry pathways that bypass bridges and provide a complete annular pack.\r\n
Custom-tailored centralizer success with shunt tube system - Halliburton
Successful deployment of non-shrouded, un-centralized shunt tube gravel pack systems can present challenges that result in premature shunt tube damage, which requires rerun and significant NPT. This occurs when the lower completion string passes through the set liner hanger with an internal castellation profile.
Development and Qualification of Enhanced Shunted Screens …
2020年10月19日 · In challenging environments (e.g., low frac pressure), gravel packing with shunt tube technique is the preferred option. This paper discusses development and qualification of an enhanced shunted alternate path technology (ESAPT) screen that will extend openhole gravel packing lengths to more than 7,000 ft with zonal isolation.
VØ-Rated Openhole Gravel-Pack System | Weatherford …
With shunt-tube technology (STT) sand screens and an STT-equipped TerraForm® packer, the WFXØ system enables single-trip gravel-pack slurry delivery. The shunts help to sequentially transport the slurry to each gravel-pack zone in a single pump operation.
