Interpolation of geophysical data using continuous global surfaces. Combination of seismic reflection and constrained resistivity inversion with an application to 4D imaging of the CO 2 storage site, Ketzin, Germany. īergmann, P., Ivandic, M., Norden, B., Rucker, C., Kiessling, D., Luth, S., et al. Influence of seismic diffraction for high-resolution imaging: Applications in offshore Malaysia. 3D inversion of ERT data on an archaeological site using GPR reflection and 3D inverted magnetic data as a priori information. Compared with the multi-scale inversion and other methods that enhance the resolution by optimizing the inversion algorithm, this method can more intuitively determine the specific boundary of anomalies in the inversion cross-section.Īrato, A., Piro, S., & Sambuelli, L. This research improves the accuracy of interpretation results and realizes high-resolution imaging. This method can amplify the data features at the boundary of anomalies by performing the secondary processing and analysis on inversion results, thereby identifying the specific boundary of anomalies. This paper proposes a high-resolution imaging and interpretation method for ERT based on reflection coefficient analysis. Although the resistivity distribution in the detection area can be obtained according to the inversion result, it is difficult to resolve the specific boundary of anomalies directly, which will affect the accuracy of the interpretation results of the detection data.
In practical applications, the smoothness-constrained least squares method is usually used to invert the apparent data of ERT. Electrical resistivity tomography (ERT) is a widely used method in geophysical prospecting.
