From these measurements, the true resistivity of the subsurface can be estimated. The ground resistivity is related to various geological parameters, such as the mineral and fluid content, porosity and degree of water saturation in the rock. Electrical resistivity surveys have been used for many decades in hydrogeological, mining and geotechnical investigations. More recently, they have been used for environmental surveys. To obtain a more accurate subsurface model than is possible with a simple 1-D model, a more complex model must be used. In a 2-D model, the resistivity values are allowed to vary in one horizontal direction (usually referred to as the x direction) but are assumed to be constant in the other horizontal (the y) direction. A more realistic model would be a fully 3-D model where the resistivity values are allowed to change in all three directions. In this research, a simulation of the cone penetration test and 2D imaging resistivity are used as tools to simulate the distribution of hydrocarbons in soil.

Using an advanced CPTe method with nuclear logs the detailed subsurface structure can be reconstructed and also the grain size distribution can be determined. Based on this information the accumulation zones and the migration routes can be identified. The migration process takes time while the degradation of the hydrocarbon contamination is going on. Laboratory tests proved that during this process the electrical properties of the hydrocarbon change significantly. It means that from the electrical resistivity of the contaminated soil may refer to the degree of degradation and consequently to the migration time. This study presents a field experiment focusing on the determination of migration routes of subsurface hydrocarbon contaminants based on the data of advanced CPTe data. © (2015) by the European Association of Geoscientists & Engineers (EAGE).
