Mechanistic induced polarization (IP) models describe the relationships between physical properties of geomaterials and their frequency-dependent complex conductivity. However, practitioners rarely use mechanistic to interpret IP data because uncertainties associated with estimating petrophysical from conductivity spectra are still poorly understood. We propose a framework for critically assess...

In this work we establish reliable correlations between density and magnetic susceptibility in three paramagnetic granites from the Pyrenees. total, 128 sites (310 measurements >2600 ones) were studied Mont Louis-Andorra, Maladeta Marimanha granitic plutons covering main range of variability susceptibility. Regressions calculated for every body an integrated linear function was obtained enti...

Abstract Cretaceous is the key exploration target layer in eastern depression of North Yellow Sea basin, which has a good prospect for oil and gas exploration. Its huge resource potential attracted great attention from petroleum geologists. In this study, main rock types, reservoir space petrophysical characteristics controlling factors are studied through core observation, thin section identif...

The work is carried out approbation of the algorithm for complex interpretation geophysical data using classification algorithm. Distributions by class are obtained and compared with petrophysical materials from published sources. This geological composition studied area obtained. applicability this approach integrated shown, including low-level areas a structure.

Due to their widespread availability, sandstones are commonly used as a natural stone for buildings, monuments and sculptures. In thecurrent study, nine sandstone samples from the Upper Red Formation (specified by the letters A, B, C, CG, S, S1, Sh, Tr and Min)were studied from a petrophysical point of view and their durability was evaluated. Then, their suitability as building stones wasassess...
