In February, 2018 the Commission directed the COGCC to convene a stakeholder group consisting of representatives from industry, local governments, NGOs and COGCC staff to examine current and developing instrument-based technologies and processes for preventing and detecting leaks and spills from flowlines, and continuing to eliminate risks from flowlines, including the location of flowlines.
In order to facilitate the Workgroup’s understanding of various instrument methods, their application and risk, staff have engaged with Colorado State University (CSU) and Colorado School of Mines (CSM) to perform literature reviews on available monitoring methods and risks models, which could be applied towards flowlines.
Literature Reviews (October, 2018)
- Current and Near-term Technology Options to Detect Leakage of Hydrocarbons, Water, and Gas from Flowlines (Colorado State University)
