Inversion of seismic reflection data has been available to interpreters in the oil and gas industry for more than twenty years. Converting the seismic wiggle data to Acoustic Impedance (AI) offers a display more comprehensible to the eye and more understandable by engineers, geologists, and managers. The availability of more advanced methods and more powerful computers promotes seismic inversion into a practical methodology which is not only performed by geophysicists, but also geologists and even petroleum engineers. Nowadays, due to its wide popularity, this technique is commonly treated as a must-basic geophysical_ method in reservoir characterization and tend to be abused by sacrifying the effectiveness of the inversion technique itself. This paper discusses the applicability of several popular seismic inversion methods, especially their strengths and weaknesses in estimating specific reservoir properties attributed to the defined goals in field exploration, development and management.
