Interpretation Method

Tilt angle filter is an interpretation method that is used to determine the source borders locations from potential fields data. Moreover, the tilt angle is applied for estimation of the anomaly source depth, such as contact-depth method and tilt-depth method. In this paper an application of the tilt angle technique obtained from the first vertical and horizontal gradients of the gravity anomaly from semi-infinite vertical cylindrical source is described. The technique is based on the tilt angle and derivatives ratio. In this approach the depth estimates are proportional to the computed tilt angles and their distances from the cross section center of the anomaly cause on the surface. This new method is termed the tilt-distance-depth (TDD). The method is demonstrated using synthetic gravity data, with and without random noise, and real gravity data from Iran. The results are also compared with the solutions from Euler deconvolution technique and inverse modelling using Modelvision software.

Abstract: Depth estimation of magnetic source bodies in parts of the Schist Belt of Kano, using Euler Deconvolution is presented in this paper. Detail ground magnetic survey was carried out using SCINTREX proton precession magnetometer to produce the Total Magnetic Intensity (TMI) map and consequently the residual map. The TMI ranges from 34,261 nT to 34,365 nT, while the residual field ranges from -160 nT to 115 nT. The depth estimate for contacts ranges from 6.5 m to 39.8 m, while that of dyke ranges from 8.9 m to 51.3 m. The depth estimation presented in this work is compared with the results of aeromagnetic study carried out in the same area and found to agree fairly well. Further, this also ensures the validity of aeromagnetic investigation in such applications. Keywords: Contacts, Dykes, Euler Deconvolution, Schist Belt. PACS: 91.25.F and 91.25.Rt.

2D seismic reflection data and magnetism data, gravity data and electrical data together define the overall subsurface structure of the East Gobi basin (EGB), and reflect Jurassic-Cretaceous intracontinental rift evolution through deposition of at least five distinct stratigraphic sequences. Three major NE-SW trending fault zones divide the basin[. In the paper, through strata sequence description and sedimentary facies analysis, as well as zone appraisal for the oil and gas in the study area, we conclude that western step-fault zone of the block VI of EGB was most favorable pay, then the reverse faulted-nose structure in the east, while in the western slope and eastern fault zone, their hydrocarbon prospect need further proved.

Magnetic Gradients

Application effect of magnetic gradients data continuation from undulate surface to plane has been analyzed by model test. The gradient data of before and after the processing was used for the analytic signal and the Euler deconvolution method calculation respectively, comparing the calculated results show that the maxima of analytic signal calculated by gradients anomaly on undulate surface deviate obviously from the center location of the prism magnetic source, and the position of prism boundaries are not clear. However, the analytic signal calculated by gradients anomaly after continuation from undulate surface to plane can be successfully used to estimate the center and boundaries position of prism. The solutions of Euler deconvolution method calculated by gradients anomaly on undulate surface are dispersive, the solutions calculated by gradients anomaly after continuation from undulate surface to plane are relatively clustering, and can outline clearly the positions of prism corners. The results demonstrate that continuation from undulate surface to plane processing of gradients anomaly can improve the application effect of analytic signal and Euler deconvolution technique.
