Abstract


This study deals with the fault displacement analysis carried out for the major fault, located in the Penobscot prospect of the Scotian basin. Initially a fault enhancement filtered (FEF) seismic volume is prepared from the original seismic, which is taken as input for the fault surface generation and throw values calculation from the Cretaceous formations. The calculated throw values of the major fault are then plotted against time and distance. The plotted graphs decipher the degree of tectonic activities and deformations taken place during the Cretaceous period. This helps in understanding the growth and evolution of the major fault as well as its implications in modulating the Cretaceous formations of the study area. Such analysis also provides inference about the fault linkage, depositional compartments and trapping zones for hydrocarbon accumulation.
