The Use and Abuse of AVO: Value, Analysis, Errors and Pitfalls

AVO might be considered the “holy grail” in the use of seismic data to remotely describe the subsurface in all its geological complexity of lithology, porosity, rock fabric, fluids, pore pressure and stress. As with any scientific method that claims to be a “theory of everything” there are practical approximations and assumptions that must be satisfied, along with pitfalls to be avoided, in order to achieve the promise of AVO’s superior reservoir characterization ability. This paper provides some practical considerations in the use and abuse of methods that underlie the application of AVO.
