S.I.Q.E. is an Advanced Deep Learning and Nonlinear Signal Processing technique aiming to enhance seismic data quality by improving a vertical seismic resolution and signal-to-noise ratio. The application of the product does not require prior well data such as petrophysical logs. This technique was applied to various oil and gas-condensate fields and is proven via detailed validation processes (based on acoustic, density and VSP data) considering more than 300 wells. The results of S.I.Q.E. allow for to identification of thin sand units and the continuation of layers significantly better which impacts accurate reservoir characterization optimizes well target placement and provides extensive insights prior to drilling activities.
