... that needed to be addressed, as part of the overall Play Fairway Program, was plate tectonic reconstruction. The purpose of the Plate Tectonic Reconstruction Project is to provide an integrated 3D model of the crustal structure and evolution of the Nova Scotia continental margin, in space and time, from...

... continental margins (Keen et al., 1994; Chian et al., 1995a,b; Funck et al., 2007; Gerlings et al., 2009) have proven to be pivotal in documenting the complex structure and evolution of non-volcanic margins globally (Peron-Pinvidic and Manatschal, 2008; Manatschal and Muntener, 2009), and has led...

... regions are conducive to gas hydrate formation. Numerous research programs have shown that natural gas hydrate is widespread in permafrost regions and beneath the sea in sediments of outer continental margins. Natural gas hydrates, commonly also known as methane hydrates, are clathrates, (from the Greek...

... Abstract Submarine slides pose the most critical offshore geohazard. Seafloor mass movements occur in continental margins worldwide, and at all scales, from the smallest ones, barely detectable by acoustic methods, to the gigantic Storegga Slide off Mid-Norway. As most deepwater petroleum...

... are fuelling the quest for new oil and gas reserve along the Newfoundland and Labrador continental margin, extended now from proven basins to less explored or unexplored areas. Introduction Although the first offshore drilling occurred in 1966, only 133 exploration wells have been drilled to date...

... Basin-river system. Across the continental margin, extension occurred over the upper slope and compression along the lower slope. 1.0 Introduction The Gulf of Cadiz continental margin has been proposed as a potential world-class petroleum province 1 , 2 . The margin is a known hydrocarbon producer...

... equilibrium of the offshore environment. This paper reviews the new outlook of geophysical data acquisition off shore Brazil, its implications for the interpretation of petroleum geology andgeophysics and the future exploration of the continental margin off eastern Brazil. It succintly describes the modern...

... Abstract Research institutions in European countries conduct seismic experiments to investigate the geology of all the provinces of the ocean floor. Some objectives of deep reflection-refraction studies of continental margins are of mutual interest to academia and the oil industry...

... Abstract Gassy sediments in continental margin environments pose constraints for subsea installations because of their inherent instability under loads imposed by earthquake activity, excessive erosion and/or deposition, near-surface faulting or diapiric activity. Evaluation of processes...

... degrees C/100 m. If that value should characterize the entire Gulf of Cadiz and adjacent continental margin, then it is likely, given observed sediment thicknesses, that the area might not be commercially petroliferous. In this article, geologic arguments are presented that the regional geothermal...

... of new concessions between the 200 m and 500 m isobaths along the South African continental margin. Despite this very wide-ranging occurrence of diamondiferous deposits on the coastal plain and continental Shelf, little is known of the nature of the deposits. The occurrence of diamondiferous deposits...

.... During this period, the Gulf of Mexico was undergoing onlythermal subsidence. The main phases of intracrustal extension and sea floor spreading, the stages of basin evolution most commonly associated with tectonic hinge zone formation at other divergent continental margins, had already taken place. We...

... Abstract Multichannel seismic meaurements (MCS) together with sonobuoy data were analyzed in the shallow water portions «200 m) of the NW African continental margin. The untuned sound source and acquisition techniques were designed for use in deep water. Thus, the shallow water shelf data...

... ABSTRACT A geophysical survey off the coast of Sierra Leone was carried out in April 1983 and September 1985 to investigate the structure of the West African continental margin between the Guinea and Sierra Leone fracture zones. A large (>100 mGal) free-air gravity anomaly and an associated...

... ABSTRACT In 20 years of offshore exploration on Brazil's continental margin, PETROBRAS has performed nearly 600,000 kilometers of seismic lines and 1,100 exploratory wells, totaling approximately 3.7 million meters drilled. As a result of such an effort, in-place oil -volume discovered amounts...
