SONICGAUGETM BVS

BARRIER VERIFICATION SYSTEM

  • 170+ years of accumulated downhole monitoring time globally (350+ installations)
  • Can provide surface-read-out (SRO) of downhole data without intervention
  • Deployed on the bottom of a plug or packer with no additional rig time (single run)
  • Fully wireless: no wellhead penetrations, downhole cables, or connectors required

OVERVIEW


The SonicGauge™ Barrier Verification System (SG-BVS) is a two-way (duplex) acoustic telemetry system that measures and wirelessly transmits wellbore pressure to surface in real-time to verify the integrity of a downhole barrier, such as a retrievable bridge plug, storm packer or inflatable packer.

When conducting well-plugging operations, the long-term pressure integrity of the barrier is critical. Typically, the barrier is inflow tested from below, or pressure is applied from above to ensure the plug is holding pressure. However, these tests are carried out shortly after the plug is deployed and, as such, do not offer ongoing assurance of barrier integrity.

The SonicGauge BVS can be deployed with mechanical plugs, storm packers, inflatable packers or metal barriers to monitor the initial pressure test and provide ongoing pressure measurement to confirm continued well isolation for up to eight years.

INTEGRATION WITH
DSL, E-LINE & SLICKLINE


Leveraging over a decade of well testing and multi-year reservoir monitoring via wireless communication, Acoustic Data can interrogate and reprogram the SonicGauge BVS via the SonicSync™ Command+Control Platform directly from surface or via a slimline well intervention tool.


SONICSYNC™ WELLHEAD MODEM

A command tool driven by a laptop interface is temporarily attached to the wellhead/tubing hanger flange to send acoustic commands downhole to activate, control or check the status and diagnostics of downhole equipment. Depending on the depth, SonicRepeater stations are deployed along the tubing to boost the range of the system—effectively providing an unlimited transmission distance.


SONICSYNC™ INTERVENTION MODEM

A short-hop wireless downhole communication system deployed via slickline (pre-programmed, data to memory) or wireline/digital slickline (real-time commands sent from surface, real-time data sent to surface), which can interrogate SonicGauge sensors located below barriers, such as a retrievable bridge plug, hurricane packer, tester valve or DHSIT.


SONICREPEATER PICK-UP

Alternatively, a SonicRepeater tool can be deployed on the Barracuda HEX-Hanger above the barrier to receive, decode and store the downhole data sent from the SonicGauge sensor below the barrier. Periodically, this tool can be retrieved via slickline to download the downhole data before being reinstalled for continued data acquisition.

SURFACE OPTIONS


SOLAR POWER MODULE
Fully independent and compact system using solar energy to power the SonicGauge™ Data Logger (SDL).
MODBUS / SCADA
Downhole data can be routed to your desktop via a Modbus interface that connects to your remote terminal unit (RTU) at wellsite, providing a complete 'Downhole to Desktop' solution.
3G/4G-WIFI MODULE
This module can be connected to an operator's network directly or via a secure VPN tunnel. For smaller clients, the VPN server can be hosted by Acoustic Data as a cloud solution. The SonicGauge™ Data Logger (SDL) is enabled to receive over-the-air (OTA) firmware updates and transmit real-time downhole data without the need for a remote terminal unit or physical intervention.
EXD ENCLOSURE
For hazardous zone deployments, we offer a Zone 1 rated EXD Enclosure and Solar Power Module solution.
ANTI-THEFT / VANDAL MODULE
For locations where theft or vandalism of surface equipment is a concern, we offer secure armoured vaults or secure subterranean modules for installation at the wellsite. Please enquire for tailoring a system to your requirements.
SUBSEA INTERFACE
The SonicGauge™ Data Logger (SDL) is being integrated into an industry-leading Subsea System for multi-year data acquisition. For more information, please contact our team.
