New PHMSA Guidelines

The US Department of Transportation, Pipeline and Hazardous Materials Safety Administration (PHMSA) has released a set of guidelines for conducting risk assessments of underground gas storage wells that are subject to periodic well entry. The guidelines, developed by C-FER Technologies, are publicly available on the PHMSA website.

Webinar Series

C-FER is hosting a two-part webinar series outlining the quantitative risk assessment (QRA) process that form the basis for the guidelines.

Part one will cover the two key process elements: risk estimation and risk evaluation. The discussion will include a review of the analysis methods and modelling options and how to use the estimation results to inform well design and integrity management. Register

Part two will review the demonstration analyses that illustrate the application of the QRA process. These analyses also formed the basis for the directional findings that are intended to support the development of best practices for different well completion types and well entry practices.
