Study of Hydrocarbon Saturation by Geophysical Methods

The contamination of soil and groundwater by LNAPLs is a problem that has been treated over several years, because, they are used in the industrial worldwide. Its location and behavior in the subsurface has been monitored through invasive methods that disturb the environment and they are costly. In this sense, we integrated a noninvasive hydrogeophysical method as Ground Penetrating Radar (GPR)...

Monte Carlo Methods in Geophysical Inverse Problems

[1] Monte Carlo inversion techniques were first used by Earth scientists more than 30 years ago. Since that time they have been applied to a wide range of problems, from the inversion of free oscillation data for whole Earth seismic structure to studies at the meter-scale lengths encountered in exploration seismology. This paper traces the development and application of Monte Carlo methods for ...

Evaluation of Geophysical methods for identifying hidden Quaternary faults in alluvial sediments (case study: Chitgar Park)

Abstract In this research, Geophysical methods Ground Penetration Radar (GPR) and Geoelectric have been used to detect hidden Quaternary faults in alluvial sediments located southwest of Chitgar Forest Park (District 22 of Tehran). The study of profiles (GPR) identified areas such as fault. The results obtained from two Geoelectric profiles indicate that there are two zones with low electrical...

Forward modeling of geophysical electromagnetic methods using Comsol

16 In geophysical electromagnetic methods, time-varying magnetic fields are measured at Earth’s surface that are produced by electrical currents inside the Earth in order to constrain subsurface conductivity and geological structure. These methods are widely used for mineral exploration and environmental investigations, and are increasingly being used in hydrocarbon exploration as well. Forward...
