A profitable development of an oil or gas field start with a good understanding of the subsurface as a basis for efficient and successful field management. The use of AVO and inversion
techniques helps to create the best possible petro physics subsurface model. Improved discrimination of reservoir units are made and models are generated using logs and seismic
data. These techniques lead to highly accurate or highly probable subsurface models compatible to dynamic reservoir models obtained from reservoir engineering measurements and computations. The correct use of seismic attributes, well data analysis, AVO and seismic inversion is essential to establish subsurface models that can be used for improved field
development planning and design.
