Bedrock launches node for injection pressure reporting at wellheads

Feb. 7, 2022

Bedrock Automation announced Jan. 6 the immediate availability of its secure, turnkey solution for automated remote monitoring, reporting and control of underground injection water pressure at wellheads. The underground injection control (UIC) system handles all data monitoring, analysis, control and reporting necessary for complying with California Code of Regulations Title 14 § 1724.10.4, and includes secure, advanced process control capabilities for optimizing well sites.

“The state of California requires stringent monitoring of pressure being injected to aid water flood, and the deadline for such compliance has already passed. Non-compliant wells are subject to fines up to $25,000 a day," said Albert Rooyakkers, founder, CEO and CTO at Bedrock. "In just days, we can set up a secure monitoring system via the cloud that eliminates risk of fines, while improving pressure monitoring and reporting performance.”

UIC's monitoring and reporting system lets midstream users:

  • Collect real-time data from field-based sensors and issue monitoring status over the cloud;
  • Securely send continuous data to a cloud DAQ system;
  • Prevent operating fees and over-pressure violations at injection sites by safely monitoring and controlling pressure at the wellhead;
  • Implement controller-based alarm detection and mitigation tools;
  • Maintain decades of secure digital records (California regulation requires a minimum of three years after the well stops operating); and
  • Implement automated, closed-loop pressure management that could replace monthly reporting once approved by regulators.

To perform pressure monitoring and reporting tasks, UIC blends control and communications. Its heart and brain is Bedrock's OSA Remote control system. It receives pressure readings and production data from up to 20 pressure sensing devices, processes related control logic, and exchanges data with the cloud or SCADA system via MQTT or OPC UA.

It also includes 64 GB of secure onboard flash memory that can store injection data for decades. And, like all Bedrock products, OSA Remote is intrinsically cybersecure.

Complementing OSA Remote, UIC's components include:

  • Cellular radio that carries data signals from OSA Remote to the cloud or SCADA application;
  • Universal terminal assemblies (UTAs) that simplify access;
  • Power disconnect and distribution unit that manages 24 VDC for safe, easy troubleshooting; and
  • Embedded SCADA dashboard for secure wireless visualization.

UIC also runs on any 24 VDC power supply, including direct solar arrays. However, it can also be specified with Bedrock's SPS.500 primary power supply and/ora UPS.500 uninterruptible power supply (UPS) that also provides enhanced availability, advanced diagnostics and Bedrock’s intrinsic cybersecurity.
