Abstract: A suite of methods has been developed to tackle the special geology of carbonate reservoirs in northern Tarim Basin. These methods include 3D fine seismic imaging, 3D coherence cube, seismic attribute extraction; impedance inversion, 3D visualization interpretation, image longing, long distance sonic logging and fracture probability model. The fracture and karst development zones in carbonate reservoirs predicted by the suite of the methods are verified by drilling.
