The TaskOp Underground Gas Storage (UGS) Risk Model v2 was developed in response to the release of API RP 1170 and API RP 1171 Second Edition and the PHMSA Underground Gas Storage regulations effective January 1, 2026. 

The model includes advanced features such as threat interaction tables, comparative risk scoring, and interactive dashboards to help operators manage UGS well, reservoir, and cavern risk. After answering structured assessment questions through an easy-to-use dropdown interface, the system generates clear data visualizations that allow operators to: 

  • Analyze well and reservoir risk scores 
  • Compare risk across storage pools and operating years 
  • Identify threats and prioritize risk reduction actions 

Preventive and Mitigative (P&M) Measure Identification

Preventive and Mitigative (P&M) measures are a core requirement of UGS integrity management programs. Operators are expected to actively identify and implement measures that reduce well and reservoir threats. 

The TaskOp UGS Risk Model includes a built-in library of Preventive and Mitigative measures designed to help operators strengthen their integrity programs. Based on responses within the risk model assessment, TaskOp can automatically flag recommended P&M actions tailored to the operator's system and risk profile. 

To further streamline compliance workflows, TaskOp can also: 

  • Generate mitigative field crew work orders 
  • Push actions into existing asset management or maintenance systems 
  • Track implementation of risk reduction activities 

Key Capabilities of the TaskOp UGS Risk Model

The TaskOp UGS Risk Model v2 provides underground gas storage operators with advanced tools for risk analysis, threat interaction evaluation, and integrity management decision support, including: 

  • Real-time comparative risk results across wells, reservoirs, and caverns 
  • Visibility into interacted and non-interacted threat scoring results 
  • A threat interaction matrix that allows users to retrieve and display analytical risk data 
  • Comparative analysis of threats, threat interactions, and consequences across the well or reservoir fleet 
  • Aggregated total risk scoring to support system-wide decision making 
  • Interactive charts and graphs that visually communicate UGS risk assessment results 
  • A Risk Metrics dashboard highlighting key integrity management indicators 
  • An advanced risk analysis dashboard with filtering, statistics, and visual outputs 

The result is a comprehensive underground gas storage risk management tool that helps operators meet PHMSA UGS compliance requirements, implement API RP 1170/1171 risk management practices, and make faster, data-driven integrity management decisions.
