IIoT & SCADA Modernization for Texas Oil & Gas
Houston refineries, Permian Basin upstream, Corpus Christi midstream — connecting legacy OT infrastructure to real-time analytics, predictive maintenance, and OT cybersecurity without stopping production.
Texas accounts for approximately 40% of US crude oil production and hosts the country's largest refinery complex along the Gulf Coast. Unplanned downtime in Texas refining and petrochemical operations costs an estimated $100,000-$500,000 per hour depending on facility size and product type. The primary causes — aging instrumentation with no real-time data, reactive-only maintenance programs, and OT/IT network silos preventing data flow from field devices to business systems — are solvable with modern IIoT architecture. Ajinkya Technologies deploys OPC UA and MQTT Unified Namespace architectures that connect legacy DCS, PLC, and SCADA systems to cloud analytics without replacing operational technology. For Permian Basin upstream operations, this means well performance monitoring and artificial lift optimisation. For Gulf Coast refining, it means condition-based maintenance on rotating equipment, heat exchangers, and compressors. The architecture is IEC 62443-aware, NERC CIP-aligned for transmission-adjacent operations, and deployable without production shutdown.
What We Build for Texas Energy
Six capabilities for upstream, midstream, and downstream Texas operations — IIoT-first, OT-cybersecurity-aware, and engineered for brownfield retrofit without production stoppage.
- OPC UA Retrofit: legacy DCS/PLC connectivity via Modbus, DNP3, and proprietary protocol gateways — no rip-and-replace
- Predictive Maintenance: vibration, current-signature, temperature, and pressure sensor analytics on rotating equipment, heat exchangers, compressors
- SCADA Modernization: cloud-connected SCADA layer with edge resilience; existing operator HMIs unchanged
- OT Cybersecurity: network segmentation, IEC 62443-aware architecture, NERC CIP-aligned remote access, anomaly detection on industrial protocols
- Permit-to-Work Digital System: electronic permit issuance, contractor verification, isolation tracking
- Agentic AI for Operations: multi-agent triage on production alerts, maintenance work order creation, and exception escalation

Frequently asked questions
What IIoT solutions does Ajinkya Technologies offer for Texas oil and gas?
Ajinkya Technologies delivers OPC UA and MQTT-based IIoT connectivity for Texas oil and gas operations — upstream Permian Basin well monitoring, midstream Corpus Christi pipeline SCADA, and Houston downstream refinery modernization. Solutions include condition-based predictive maintenance using vibration and current-signature sensors, OT/IT network segmentation, IEC 62443-aware architecture, NERC CIP-aligned remote access, and real-time anomaly detection on industrial protocols.
Can Ajinkya Technologies modernize legacy SCADA systems in Texas refineries without production stoppage?
Yes. Ajinkya Technologies specialises in brownfield SCADA modernization — retrofitting OPC UA connectivity to legacy DCS and PLC equipment without rip-and-replace. The approach connects existing Modbus, DNP3, and proprietary protocol devices to a modern IIoT data layer, enabling real-time analytics and predictive maintenance while the plant continues production. Typical connectivity deployment: 6-8 weeks per facility.
