New Lower Tertiary play trend identified in the West Orphan Basin, Offshore Newfoundland

摘要

Over the past five years, extensive 2D long offset broadband seismic data (110,000 line km) has been acquired offshore Newfoundland and Labrador, Canada. These new seismic programs have targeted the underexplored slope and deepwater areas of the province's offshore and were planned using potential fields and satellite seep data. In the West Orphan Basin portion of the program, a new Lower Tertiary fan and turbidite play trend has now been identified. This newly identified play trend is characterized by Class II AVO signatures and was not visible in legacy short cable seismic data. To further delineate this area, a 3D long offset broadband seismic survey was acquired over a part of this play trend in the summer of 2015 and the early data from the new 3D has provided enhanced definition of the depositional setting and sediment pathways, provided evidence of potential hydrocarbon sourcing and migration, and has imaged material sized prospects.
