Fluid substitution is an important part of the seismic rock physics analysis (e.g., AVO, 4D analysis), which provides a tool for fluid identification and quantification in reservoir. This is commonly performed using Gassmann’s equation (Gassmann, 1951). Many authors (Batzle and Wang, 1992; Berryman, 1999; Wang, 2001; Smith et al., 2003; Russell et al., 2003; Han and Batzle, 2004) have discussed...

Seismic reservoir characterization is a well-known technique to obtain a better understanding of hydrocarbon-bearing reservoirs by careful analysis and integration of petrophysical and seismic data. The petrophysical properties are normally obtained through the evaluation of well logs and core data. A rock physics model provides the link between these reservoir properties and the surface seismi...

In oil industry, recovery of crude oil can be improved by injecting aqueous solutions containing surfactants, polymers, and mineral ions into an oil reservoir. This process is called enhanced oil recovery. Water and oil are immiscible, separated by an interface, and their motion through a capillary tube is governed by the surface tension. However, the physics can be more complex during an enhan...

marc h 20 09 JE A N -F RA N CO IS P O D EV IN Our intuition, going back forever, is that to move, say, a rock, one has to touch that rock, or touch a stick that touches the rock, or give an order that travels via vibrations through the air to the ear of a man with a stick that can then push the rock—or some such sequence. This intuition, more generally, is that things can only directly affect o...

Abstract The phase of CO 2 present in a saline reservoir influences the change pore geometry properties rocks and consequently transport storage integrity reservoir. In this study, digital rock physics was used to evaluate saturated with different phaseCO -brine under conditions. changes due -brine-rock interaction were quantified. addition compression, caused further reduction porosity by prec...

The Earth Materials Area is comprises the Experimental Petrology, Rock Physics, Thermochronology and Structure & Tectonics Groups. The research of these groups centres around laboratory based measurements under controlled conditions, simulating those occurring in nature, but these activities are complimented by field based observations, often in collaboration with scientists from other institut...

We highlight the importance of transit observations on understanding the physics of planetary atmospheres and interiors. Transmission spectra and emission spectra of atmospheres allow us to characterize these exotic atmospheres, which possess TiO, VO, H2O, CO, Na, and K, as principal absorbers. We calculate mass-radius relations for water-rock-iron and gas giant planets and examine these relati...

Underground muon events detected by the MACRO experiment at Gran Sasso have been studied for different purposes. The studies include the vertical muon intensity measurement, multiplicity distribution, lateral and angular muon distribution and searches for substructures inside muon bundles. These analyses have contributed to bring new insights in cosmic ray physics, in particular in the framewor...
