Accu-Pulse™ Incremental Positioning Module

Enhance Reservoir Management by Incrementally Controlling Produced or Injected Fluid Rates

Halliburton's Accu-Pulse™ incremental positioning module is a complementary control module that allows operators to control produced or injected fluid rates to the desired quantity by incrementally opening a multiple-position interval control valve (ICV).

The Accu-Pulse module works in tandem with either Halliburton's Digital Hydraulics™ or Direct Hydraulics downhole control systems, and with Halliburton WellDynamics’ HS-ICV multiple-position downhole control valve. It can be matched with an HS-ICV standard flow trim design (oil or gas) to optimize the system for a wide range of applications, such as gas injection or commingled production, or to an HS-ICV customizable flow trim design to meet specific operational requirements.

The Accu-Pulse module provides effective incremental control of an ICV in a range of applications, such as:

  • Internal gas lift
  • Waterflood
  • Gas injection
  • Commingled production


  • Enhance reservoir management through control of produced or injected fluids
  • Accurately estimate and allocate flow
  • Avoid reservoir drawdown
  • Ensure a high level of well control for internal gas lift, Waterflood and commingled flow


  • Hydraulic, incremental control
  • Ability to close valve from any position in one press cycle
  • Provides up to 11 discrete positions with appropriate ICV
