TTI/HTI Anisotropy for Fracture/Faults Image Inside Granite Basement

In this paper, we present a case study of improving the fracture imaging inside granite basement by incorporating the TTI/HTI anisotropy for the first time. With the help of the Controlled Beam Migration (CBM) stack sweeping technology, the new velocity modeling flow can estimate the azimuth information for the fracture system and improve the imaging quality inside the basement, which provides the much needed information for the effective exploration in the Cuu Long Basin offshore Vietnam.
