NovaSpan

The areas from the Canadian/U.S. boundary to the prospective waters offshore southern Newfoundland have lacked a consistent regional seismic framework. Furthermore, this area is in need of depth imaging to properly target deep shelf reservoirs and identify untapped reserves. In order to provide a more comprehensive understanding into the geologic evolution and basin architecture of the margins of Nova Scotia and Newfoundland, GX Technology (GXT) designed NovaSPAN.

NovaSPAN was designed with the active participation of oil & gas companies and regional experts, with the goal of better understanding the regional geology and more specifically, the deeper, less explored areas of the basin. Utilizing its Image-Driven approach, GX Technology managed the entire project to ensure the highest-quality survey design, acquisition, and processing technologies were applied. 

Key program components include:

• Program design and physical layout driven by geology
• Over 3,300 kilometers of new 2D seismic acquisition
• Unprecedented deep focus:  17 second record time and 9,000 meter offsets
• Integrated geologic and geophysical interpretation
• Transects key geologic features, placing them in a basin-wide context
• Provides previously missing data to allow direct correlation of older stratigraphy from the shelf to the deep basin
• Improves understanding of depositional fairways and facilitate basin-wide stratigraphic correlation
• Illustrates regional variations in structural style above multiple salt layers
• Provides insight into underlying crustal architecture of horsts, grabens, oceanic crust, and fracture zones
• Applies technical specifications of acquisition and data processing to optimize event continuity and imaging of deep objectives
• Minimizes the effects of water bottom multiples with critical line placement and application of advanced technology
• Depth images the seismic data to maximize quality of images and facilitate geologic correlation
