Abstract
Acquiring multi-component data has been around for quite a while and the value of combining the compressional and shear information have been known for a long time. However, the cost of acquiring and processing multi-component data has been high and the quality of the PS data has sometimes been inadequate. With the significant recent progress made on acquisition and processing technologies, and computational cost becoming much lower, it is now viable to utilise the full benefit of employing PS data in reservoir characterisation studies. This paper gives a clear need to process the PS data and take it through inversion to be jointly used alongside conventional PP data. Our work shows that PS adds a significant value in estimating elastic properties that impacts the accuracy of consequent geological and fluid flow model built based on these properties.
