a detailed study of the exploited geothermal field of travale in italy was conducted using magnetotelluric (mt) data in 2004. this paper detects the main features of the conductivity structures of this area. for subsurface mapping purpose, the long period natural-field mt method proved very useful. for processing and modeling of the mt data, 2d inversion schemes were used and to have the best p...

the targeted area of this research includes e anatoly, nw zagros, and caucasus. these structures are known as a complex and active area and in the early stage of continent-continent collision, which give us unique possibility to monitor such collision in real time. therefore, it is very important to study this active area to have a better knowledge about its tectonic behavior and lithospheric s...

We have applied an automatic interpretation method of potential data called AN-EUL in unexploded ordnance (UXO) prospective which is indeed a combination of the analytic signal and the Euler deconvolution approaches. The method can be applied for both magnetic and gravity data as well for gradient surveys based upon the concept of the structural index (SI) of a potential anomaly which is relate...

on 26 december 2003 at 05:26lt (01:26gmt), a catastrophic earthquake mw 6.6, seismic moment (6 – 9 ×10 nm) struck the city of bam in the kerman province of southeast iran. the intense shaking in the city caused the complete collapse of nearly every building in the central parts of the city including many of the newer buildings, killing about 40000 people officially. the city lies to the east of...

pore pressure is an important parameter, in exploration and production of hydrocarbon resources. lack of accurate knowledge about pore pressure, before drilling phase, leads to serious dangers in drilling process. accurate knowledge about distribution of pore pressure in a field, leads to reduce risks in drilling, improve well planning and mud weight calculations. during burial, normally pressu...

This paper presents a practical case study of data-driven magnetostatic finite element solver applied to real-world three-dimensional problem. Instead using hard-coded phenomenological material model within the solver, computing approach reformulates boundary value problem such that field solution is directly computed on measurement data. The formulation results in minimization with Lagrange mu...
