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.
Using enhanced shunt screen technology
OptiPac XL extended-length Alternate Path gravel-pack screens reduce the number of development wells required to access reserves by enabling long, complete gravel packs through multiple zones using enhanced shunt screens. Alternate Path technology provides a means of bypassing sand bridges that prevent long gravel packs when using conventional screens in difficult conditions such as small fracture windows, poor wellbore stability (hole collapse), presence of reactive shale, or filtercake damage with high leakoff.
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. These changes enable gravel packing in HPHT wells with high-density fluid and high shunt friction. The OptiPac XL screen also increases the rate capability, accelerating gravel-pack operations and thus reducing rig time for sand control pumping.
We provide integrated services for gravel packing with alternate path screens that include gravel pack pumping design software, pumping equipments, service tools, shunt tube isolation valves, open hole shunted mechanical packer, and gravel packing fluids.
