LEAK ISOLATION WELL COMPLETIONS SYSTEMS

Leak isolation compeltions systems
  • Long term isolation of water producing interval or leak below pump
  • For selective production of either interval situated above or below isolated interval
  • Completions system setting type hydraulic-mechanical. Upper packer hydraulic, lower packer- mechanical (axial setting type)
  • Released by standard overshot

STRADDLED LEAK ISOLATION COMPLETION WITH ESP

Leak isolation compeltions with ESP
  • Isolation of the leak of casing where leak above of dynamic fluid level
  • Straddled completion allows complete isolation of leak
  • Gas bypass valve can be part of compeletion
  • Axial type of completion setting (no rotation)
  • Sealing of ESP cable without splice – by pulling of the cable through sealing elements of straddle (no cable armour damage)
  • Release of completion by pulling force
  • Bypass system for pressure equalization

ABOVE ESP LEAK ISOLATION COMPLETION

Integrity isolation above ESP completions systems
  • Isolation of the leak of casing where leak above of dynamic fluid level
  • Capillary pipe as a part of completion for chemicals pump to ESP zone
  • Axial type of completion setting (no rotation)
  • Sealing of ESP cable without splice – by pulling of the cable through sealing elements of straddle (no cable armour damage)
  • Release of completion by pulling force

WATER RE-INJECTION COMPLETION

Water re-injection completions systems
  • Designed for pressure maintenance by re-injection from lower water bearing zone to upper pay zone
  • Axial type of completion setting (no rotation)
  • Sealing of ESP cable without splice – by pulling of the cable through sealing elements of straddle (no cable armour damage)
  • Release of completion by pulling force

SELECTIVE WATER INJECTION WELL COMPLETIONS SYSTEMS

Selective water injection completions systems
  • Selective water injection in different reservoirs
  • Mono-tubing completions systems
  • Axial type of completion setting (no rotation)
  • Ability to perform logging through completion
  • Rate changes by replacement of choke valves in mandrels

SELECTIVE TREATMENT WELL COMPLETIONS SYSTEMS

Selective treatment completions systems
  • Selective treatment of multi-layer formation
  • Axial type of completion setting (no rotation)
  • Multi-setting in one run of completion
  • Pressure differential up to 70MPa
  • Bigger ID for volume injection
