FORCE Webinar  Improved understanding of seepage in and around abandoned wells
Channel: Force Seminars
Date: 2021-06-14

Approximately 3000 wells drilled on the Norwegian Continental Shelf have already been decommissioned, and an equal amount is expected to be plugged and abandoned (P&A) in the next decade(s). Recently detected acoustic anomalies in the water column near abandoned wells suggest that fluids are actively seeping and that the well paths may have an influence on the natural migration pathways. In the three presentations of this webinar, we will give an overview of the occurrences and mechanism of natural seepages, followed by observations of seepage near hydrocarbon wells, and concluding on a proposal to study the fate of plugged wells after abandonment.
