Comment on: 'The 3D shear experiment over the Natih field in Oman: the effects of fracture-filling fluids on shear propagation' by C.M. van der Kolk, W.S. Guest, J.H.H.M. Potters

摘要

We find errors in theory and application in the paper by van der Kolk et al. (Geophysical Prospecting 49, 179-197 (2001)) that invalidate their arguments for the cause of the reduction in the velocity of the vertically propagating slower split shear-wave in the gas cap over the Natih field in Oman. We suggest that existing theories are adequate and can explain the anomaly.
