Longhorn Site Intelligence System

The new Site Intelligence System (SIS) is a customizable system that integrates with Allen Bradley PLCs and is configured using the HMI interface. It offers both remote and local distributed, centralized control with a variety of connections including remote access through a VNC or local access with an Ethernet IP, Modbus TCP/IP, and Modbus serial port, HART, physical Analog I/O or digital I/O. SIS communicates with nearly every kind of end device used for automation, measurement, and control.

What’s different about this system is its scalability. It offers well-control on each well for safer and more consistent monitoring, while its integrated remote I/O optimizes monitoring and control from the main battery.

Dramatically Reduces Startup and Commissioning Time

Operators looking to reduce time and labor during the development of new facilities or site expansions will find Longhorn’s Site Intelligence System the perfect solution. The SIS solution allows field technicians or programmers to add or remove equipment directly from the HMI screen or via its system with a built-in secure VNC, providing the ability to make changes remotely too.

The SIS’s flexibility to manage such a wide variety of controls is what makes this solution stand out. It operates to control, measurement, and communication of:

  • Tank levels
  • Alarms for hi-level shutdowns
  • Tester PSI/ LSH and LSL, to manage ESDV’s at the header or the well
  • Compressor monitoring shutdowns
  • VRU control
  • LACT monitoring and control for truck and pipeline

The Site Intelligence System can control and monitor all systems from a single wellsite to multiple well pads. Standard programming is established for a basic layout configured with 20 wells, 20 tester vessels, 10 water tanks, 10 oil tanks, 2 gun barrels, and a few other assets. The system can be quickly and easily modified to customize the actual number and configuration of assets as needed.
