magnetic data inversion has a prominent role in geo-structural investigations. as lots of geological structures, such as faults, dykes, contacts etc are elongated in a specific direction, 2d algorithms became widespread during the previous years. modifying the existing algorithms on 3d data inversion, a method has been proposed for 2d inversion of profile magnetic data, based on the physical pa...

Here in, an application of a new seismic inversion algorithm in one of Iran’s oilfields is described. Stochastic (geostatistical) seismic inversion, as a complementary method to deterministic inversion, is perceived as contribution combination of geostatistics and seismic inversion algorithm. This method integrates information from different data sources with different scales, as prior informat...

in this paper, we studied effect of different parameters including density, viscosity, interfacial tension and solute transfer concentration on phase inversion hold-up. the results showed that change in phase density ratio had no effect on phase inversion hold-up. it also disclosed that the phase viscosity ratio was the most effective parameter affecting phase inversion hold-up and each phase h...

Abstract. In Europe, formation of the Palaeozoic Variscan orogenic belt, and Mesozoic–Cenozoic Alpine–Carpathian belt led to a widespread inversion events within forelands both domains. We used legacy 2-D seismic data together with newly acquired 3-D that, for first time, precisely imaged sub-Zechstein (i.e. sub-evaporitic) upper successions in NW Poland order develop quantitative, balanced mod...

One of the most remarkable basis of the gravity data inversion is the recognition of sharp boundaries between an ore body and its host rocks during the interpretation step. Therefore, in this work, it is attempted to develop an inversion approach to determine a 3D density distribution that produces a given gravity anomaly. The subsurface model consists of a 3D rectangular prisms of known sizes ...

In this study, we apply advanced numerical optimization techniques to extend the work of Imhof and Sharma (2005, 2006) to integrate geological and geophysical data and infer the sedimentary parameters that produce a match to seismic data. In particular, we seek to match not just event timing (phase) but also reflection strength (amplitude). This inverse problem of quantitatively matching presen...

The Shanxi rift is located in the central part of North China Craton (NCC). With strong tectonic deformation and intense seismic activity, its crust-mantle deep structure have always attracted wide attention. Using teleseismic events observed a dense network 610 temporary 127 permanent stations NCC, we obtained S wave velocity structures by joint inversion method receiver functions surface disp...

Porosity is a key parameter for reservoir evaluation. Inferring the porosity from seismic data often challenging and prone to uncertainties due number of factors. The main aim this paper show applicability inversion on old vintage map spatial at level. 3D-seismic wireline log are used properties Lower Goru productive sands in Gambat Latif block, Central Indus Basin, Pakistan. formation was inte...

Traditional full-waveform inversion is a non-linear and ill-posed problem. To reduce the non-linearity of it, joint migration (joint inversion) was proposed as an alternative. Joint tries to minimize mismatch between measured modelled reflection data. One key feature its parameterization: two separate parameters, reflectivity (for amplitudes reflected events) propagation velocity phase effects)...
