Pre-stack Simultaneous Inversion of 3D Seismic Data for Velocity Attributes to Delineate Channel Sand Reservoir
Channel sand acts as stratigraphic trap for hydrocarbon accumulation in many parts of the world. Delineation of this type of reservoir is crucial as channel sand may be scarce and inaccurate location of the drilling wells could lose a huge currency. To differentiate channel sand from the host rocks, attributes such as P and S wave velocity ratio plays a vital role in the study area. The velocity ratio showed a negative relationship with the sand percentage in the formation i.e. lower the ratio higher the percentage of sand.
