The Product

The Barrier Verification System

The BVS is a market-leading barrier assurance tool. It features an inductive Transmitter module that houses pressure and temperature sensors which are fitted below any plugging device. The receiver module which is fitted above the plug to the Electronic Setting Tool (EST), also houses pressure and temperature sensors. Once all parts are configured correctly and deployed into the well, the EST records the installation of the barrier. The setting of the barrier can then be verified before a pressure test is undertaken. 

Upon performing a pressure test sensors record the pressures and temperatures from either side of the barrier, confirming its integrity. The data can be recorded within the tool when configured in memory mode, or be fed live fed to the surface.

Application

The BVS can be used to verify a temporary mechanical intervention plug or permanent mechanical or cement barriers. Run in conjunction with our EST and retrievable bridge plug it can log the setting sequence and record the pressures and temperatures across the barrier, along with the forces emitted on the completion. The system is rated up to 689 bar (10,000 psi) and 150 °C (302 °F) and is available across all tubing/casing weights. It can also be adapted to monitor reservoir pressures during a field abandonment.

Key Benefits

  • Slim design
  • Can be run on slickline, e-line, coiled tubing or pipe
  • Other sizes available on request
  • More efficient than conventional barrier testing methods
  • Provides documentable information on installed barrier and pressure test
  • Removes doubt from verifying barriers
  • Memory and surface read out versions available
  • Plug sets can be verified with assurance comparing against bank of sets already recorded
