The study focuses on the Guyana–Suriname transform margin, utilizing well and reflection seismic data. Both datasets allow the permeability stratigraphy to be interpreted. It consists of areally extensive reservoir horizons separated by intraformational shale horizons and erosional unconformities. The youngest strata are deformed by the two generations of gravity glides, which took place fairly late in post-break-up history.
Hydrocarbon shows from wells indicate that strata deformed by gravity glides are the only sedimentary packages where the vertical hydrocarbon migration dominates. Clusters of oil and gas shows have random spatial distribution in respective reservoir horizons within gravity glides. The base...

Transform Margins: Development, Controls and Petroleum Systems
This volume covers the linkage between new transform margin research and increasing transform margin exploration. It offers a critical set of predictive tools via an understanding of the mechanisms involved in the development of play concept elements at transform margins. It ties petroleum systems knowledge to the input coming from research focused on dynamic development, kinematic development, structural architecture and thermal regimes, together with their controlling factors. The volume does this by drawing from geophysical data (bathymetry, seismic, gravity and magnetic studies), structural geology, sedimentology, geochemistry, plate reconstruction and thermo-mechanical numerical modelling. It combines case studies (covering the Andaman Sea, Arctic, Coromandal, Guyana, Romanche, St. Paul and Suriname transform margins, the French Guyana hyper-oblique margin, the transtensional margin between the Caribbean and North American plates, and the Davie transform margin and its neighbour transform margins) with theoretical studies.
