ACCESS Toe Subs

Pressure Pulse Communication

Our electronic remote actuated ACCESS toe subs are a reliable alternative to conventional mechanical toe flow initiation devices. They activate from surface using a preprogrammed pressure code sequence, eliminating the risk of premature opening while performing pressure tests, cementing operations, or running inhole.

ACCESS Toe Subs

Pressure Pulse Communication

Our electronic remote actuated ACCESS toe subs are a reliable alternative to conventional mechanical toe flow initiation devices. They activate from surface using a preprogrammed pressure code sequence, eliminating the risk of premature opening while performing pressure tests, cementing operations, or running inhole.

FEATURES:

  • Installed as a standalone toe sub

  • Pressure pulse activation configured to operator specifications

  • Time delay tailored to each application for short / long opening delays

  • Programmed to open after well pressure is bled down to enable diagnostic fracture injection test (DFIT) pressure accuracies

  • Full wellbore ID

BENEFITS:

  • Unlimited high-pressure tests

  • Multiple subs can be run and activated with one pressure pulse code

APPLICATIONS:

  • Cemented or open hole

  • Wells requiring casing integrity tests to maximum pressure

  • Wells in which breakdown pressure is not exceeded with activation pressure
