In carbonate domains, the key problem is identifying where porosity exists. Exploration companies use seismic indicators with limited success to search for porosity within stratigraphic traps including reef complexes, karsting, and collapses.
Our experience in acquiring over 200,000 line km of SFD data over carbonate complex systems have shown that our sensors reliably respond to carbonate traps. SFD has been used to identify and prioritize areas of potential carbonate reservoir development and optimize the location of seismic programs to better delineate the prospects. Our clients have quickly developed high impact prospects over previously unknown reefs and collapsed features. Regional changes in geology, such as carbonate bank edges and basin edges, are also indicated by SFD.
Stratigraphic plays can be subtle and difficult to locate through traditional exploration methods. Channels, shore faces, point bars, platform buildups, erosional outliers or other stratigraphic features can hold large reserves of oil & gas, but can easily be overlooked if seismic data is inadequate.
Our experience acquiring over 250,000 line km in basins where stratigraphic traps exist has shown that our sensors reliably respond to stratigraphic traps of varying thickness, depth and extent. SFD can be used to identify and evaluate the reservoir potential of these features across sedimentary basins.
Structural play types such as fault blocks and anticlines are the primary targets in underexplored areas. SFD surveys can provide leads to these features where existing data coverage is low.
Our experience acquiring over 50,000 line km of SFD data in North America and the Middle East has shown our sensors respond to features in compressional, tensional and strike-slip regimes with potential reservoir development.
SFD can be used to identify the “sweet spots” or underlying structural features that exist in otherwise homogeneous shale basins.
In 2008, we conducted a survey in the emerging Horn River shale play in BC. As a result our client acquired a significant land position.
