Inflatable Straddle Packer

About

The INFLATE Raptor multi-cycle inflatable packer systems features a four-stage operating mechanism that enables packer inflation, annular circulation, interval testing, and complete shut-in isolation. The INFLATE Raptor can be configured as a single packer or a dual packer straddle assembly both with a standard pressure rating of 5,000 psi (10,000 psi version available). Its multi-cycle functionality allows for multiple formation evaluation tests or stimulation cycles to be performed on different zones within a single trip.

Its design features a volume-compensated balanced piston that prevents inner-component movement from inducing pressure fluctuations within isolated test zones and allows to accurately record initial shut-in pressure while preventing unintentional formation fractures. This innovation makes the INFLATE Raptor the optimal inflatable packer solution for formation evaluation and well stimulation in open hole or cased hole applications.

Features

  • Simple and reliable operation only requires axial movement and hydraulic pressure (control lines, rotation, or downhole pumps are not required
  • Innovative design eliminates squeeze pressure during packer inflation
  • Improved shut-in pressure accuracy due to zero-displacement valve design
  • Low-pressure-loss tool chassis
  • Ability to circulate while in the shut-in stage enables air/nitrogen induced hydrostatic head reduction for DST or swabbing applications
  • Filter screen protected flow path prevents solid/debris clogging
  • Backup pull-release emergency deflation mechanism available
  • Ideal for cased and open hole applications
  • Available upgrades for real-time downhole measurement systems
  • Adaptor sub extensions available for longer straddle intervals
  • Three different chassis sizes available for adaptability with an extensive range of packer types and sizes
