Course Credit: 0.15 CEU, 1.5 PDH

Underground storage is currently a 100-year-old industry and integrity has always been at its heart. Are there some lessons to take home for oil and gas?

In many Oil and Gas projects, the asset’s life can be related to reserve depletion. This is not so with storage facilities. Maintenance of aging infrastructure, together with the economic benefit versus cost, are the main drivers for defining storage lifetime. In natural gas storage, for instance, depleted reservoirs are cyclically-pressured up and down according to injection/withdrawal volumes and rates. Pressure in these reservoirs is sometimes increased above the original formation pressure. Storage sites have to sustain repeated cyclic and, sometimes, erratic loadings for many years and there is no fixed lifetime or sell-by date. What is great about storage is that there are plenty of published data to baseline and benchmark integrity performance. Oil and gas integrity regulations (NORSOK D-010, ISO 16530) brought the integrated view, management and systematic approach to decide when a well can be safely operated.

In this presentation, following questions are discussed:

What are the right questions to ask about the integrity of a storage facility?
How do you baseline reservoir and well integrity for a monitoring period that could potentially be as long as 100 years and obtain consistent results through time?
What are the forthcoming challenges and new frontiers?
What lessons learnt or upcoming challenges can be shared with Oil & Gas projects?
