3D Seismic Volume Detuning
DT-AMP™  Earthworks is pleased to announce a remarkable new product DT-AMP™.   DT-AMP™ is a new and novel post-inversion processing product suitable for applying to relative/coloured impedance or deterministic inversion results. DT-AMP™ is designed to remove residual amplitude/thickness tuning effects that will be present in relative/coloured or deterministic inversion. DT-AMP™ may be applied to any pre- or post-stack inversion output or to the results of EEI inversion, or reflectivity data after integration to bandlimited impedance.  DT-AMP™ offers a number of advantages over conventional inversion products:  • Amplitude de-tuning is performed allowing extracted amplitudes to be used more reliably during seismic interpretation. By removing thickness effects, the visible amplitudes can be directly interpreted in terms of litho-facies or property changes.  • Multiple products are supplied, with and without tuning corrections, allowing rapid comparison of results with just single interpretation horizon picks. Thicknesses, in time or depth, together with Seismic Net:Gross and sand thickness estimates are also immediately available as attributes on the workstation.  • Amplitude extraction is rapid for the interpreter as picking is more robust and only a single pick (not a top and base zero crossing) is required in order to display amplitudes and de-tuned amplitudes or seismic net pay or sand thickness estimates.  • Relative/coloured and deterministic inversion seismic cubes are not suitable for input as seismic conditioning for reservoir models due to tuning. By processing with DT-AMP™, the volumes are detuned and ready for reservoir model conditioning directly, in 3D, without the need for generating 2D seismic property maps picked between zero crossings and subsequently detuned.  Our DT-AMP™ workflow can be applied with or without well calibration data, can be applied to existing inverted volumes supplied by the client or can added to our existing workflow and services to provide additional value added products toany relative/coloured or deterministic inversion processing.
