3D Modeling the Gaspé Belt basin deformation: palinspastic restoration, kinematics and HC fluid flow

Introduction Since 150 years, the Gaspe Peninsula is recognized for its oil potential and recent discoveries of oil have led to a sustained exploration activity. During the 1990s, geological field studies have been focus on understanding the structural and stratigraphic architecture of the SilurianDevonian Gaspe Belt basin and geochemical studies have helped to identify the main source rocks. Reprocessing of seismic lines in the public domain with modern softwares enables to obtain new images of the basin structure at depth. A new 3D approach is considered in this study to unravel the complex geometry of the Gaspe Belt basin with the perspective to better understand its petroleum system. The study area is in the northeastern part of the peninsula (Fig. 1) where the largest number of oil indices (oil seeps, sounding, etc.), seismic lines and geochemical data are found.
