Prediction of Favorable Carbonate Reservoirs under Extremely Thick Salts via Poststack Facies-Controlled and Prestack Zoeppritz Equation Inversions in the Santos Basin of Brazil

Figure 1

(a) The well logging curve of the study area (black solid line for the well curve, dotted line for its low-frequency components). (b) and (c) represent the smooth regular constrained inversion with a value of 10^-3 and 10^-7, respectively (black solid line for the well curve, black dotted line for its low-frequency components; red solid line for the inversion results, blue dotted line for its low-frequency components). (d) and (e) represent the facies-controlled constrained inversion result with facies weight values of 10³ and 10⁶, respectively (black solid line for the well curve, black dotted line for its low-frequency components; red solid line for the inversion results, blue dotted line for its low-frequency components).
