natural aquifer vulnerability can be defined as reaching pollution to groundwater and the possibility to propogate in it after land contamination. this is a relative specification, with no dimension and cannot be measured; which it is not only depended on aquifer specification but also on geological and hydrological characteristics of the aquifer of the region. varieties of methods have been de...

This paper addresses one of the key components of the mining process: the geological prediction of natural resources from spatially distributed measurements. We present a novel approach combining undirected graphical models with ensemble classifiers to provide 3D geological models from multiple sensors installed in an autonomous drill rig. Drill sensor measurements used for drilling automation,...

In the Oil and Gas industry, processing and visualizing 3D models is of paramount importance for making exploratory and production decisions. Hydrocarbons reservoirs are entities buried deep in the earth’s crust, and a simplified 3D geological model that mimics this environment is generated to run simulations and help understand geological and physical concepts. For the task of visually inspect...

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...

In civil engineering infrastructural projects, information exchange and (re-) use in and between involved parties is difficult. This is mainly caused by a lack of information harmonization. Various specialists are working together on the development of an infrastructural project and are all using their own specific software and definitions for the various information types. The variety of infor...

Truncated Gaussian Simulation (TGS) is a well-known method to generate realizations of the ore domains located in a spatial sequence. In geostatistical framework geological domains are normally utilized for stationary assumption. The ability to measure the uncertainty in the exact locations of the boundaries among different geological units is a common challenge for practitioners. As a simple a...

Abstract Safety assessments in nuclear waste management typically include the analysis of thermo-mechanical (TM)-coupled processes. The TM behavior host rock is, among other aspects, dependent on prevalent geological geometry. This study aims to evaluate impact uncertainties geometry behavior. It is one very first studies aiming bring structural models and numerical simulations together. To ana...
