The Chidley Basin is an unexplored sedimentary basin encompassing the shelf to deep water of the Labrador Sea. Over 33,000 line kms of long offset 2D seismic data has been acquired since 2011 and is revealing elements of the basin extent and geometry. The lack of wells in the basin requires a combination of detailed seismic interpretation, AVO rock physics work and seafloor coring to define the potential petroleum system. Immature Paleocene source intervals with high TOC have been encountered on the shelf and can be mapped into the slope and deep water. These could provide an actively generating source in a deeper burial setting. Undrilled synrift packages exist within the Chidley basin that could provide additional reservoir and source rock intervals. Regional AVO scoping work is helping to constrain the play fairways throughout the Paleogene section. The identified AVO anomalies are commonly associated with large structural closures within a listric fault system and overlying BSRs. These early insights are indicating that exploration potential in the slope and deepwater Labrador region is high.
