Transfer zones a feature where deformational strain is transferred from one fault system to another play an important role in controlling fluid migration in the subsurface. More specifically, a synthetic transfer zone occurs where strain is transferred between two parallel normal faults in an extensional system. A previous study used surface curvatures derived from a clay model to highlight different geological features related to a synthetic transfer zone, including fault planes and relay ramps. We follow the same approach, applying our understanding to a 3D seismic survey to identify geological features related to a synthetic transfer zone. This study discusses the effect of synthetic transfer zones on an intrabasin extensional system, and describes listric normal faults and a relay ramp using the curvature and coherence seismic attributes. Our research area focuses on Penobscot, an offshore potential field in the Scotian Basin.
Potential reservoirs can be found within deltaic channels, these channels have the ability to form continuous transport systems for hydrocarbons. Distributary sand-filled channels in particular can serve as excellent reservoirs. The emphasis of this study is taking a detailed look into the sand channels within the Cree Sand of the Logan Canyon, as well as using coherence and coherent energy seismic attributes to delineate these features. Extensive studies have been performed in analysis of deltaic channel systems and their ability to act as reservoirs for hydrocarbons. The paper will follow an equivalent approach, employing 3D seismic survey data and seismic interpretation techniques to identify and map sand channels. The study area is focused on the Penobscot field, located off of the eastern shores of Nova Scotia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
