Estimating Thomsen parameters from thin coal seam targets via seismic velocity analysis methods
Project aims to apply a customised work flow to obtain estimates of Anisotropy from Seismic P-wave data that contains coal seam gas reserves. Anisotropy or Thomsen’s parameters serve as a key ingredient in the refinement of anisotropy models produced from anisotropic seismic data processing. Accurate models are required in seismic processing to produce a final image of the subsurface that is well focused and void of miss-ties. A poor final image can lead to the erroneous identification of well targets due to misguided interpretation on insufficiently processed seismic data. Hamish anticipates that implementing a customised work flow employing an array of current estimation techniques will serve to improve the robustness of estimating anisotropic parameters necessary for velocity modelling and subsequent depth imaging.
