... ABSTRACT It is difficult to estimate the properties of reservoir rocks from seismograms. One way to overcome this problem is to use full waveform inversion (FWI), which is applied to image highresolution velocities and density models. However, despite the many successful acoustic and elastic...

ABSTRACT We present a workflow for solution of upscaling problem of elastic properties of hydrocarbon reservoir rocks going from a finest scale on which hydrocarbon starts to move (nano- or micrometers – depending on the rock type) to the seismic scale. This approach is based on Rock Physics...

... ABSTRACT The mechanisms of ultrasonic attenuation in reservoir rock are known to be sensitive to multiple rock physical properties; this study focuses on ultrasonic experiments that measure the anisotropic attenuation in shales as function of hydrostatic confining pressure; four Eagleford...

... ABSTRACT Estimation of reservoir rock and fluid properties is highly dependent on the parameters used in the rock physics models. Determining water saturation is very important to estimate hydrocarbon reserves and is often computed using Archie’s equation. Any uncertainty associated...

... ABSTRACT Reservoir characterization in resource plays is required to constrain the physical properties of both the reservoir rock and fluids for production optimization. In cases where fields are being produced for the first time, robust integration of all facets of data can be useful...

This paper considers an application of nanoparticles for reservoir monitoring in order to enhance the electrical conductivity contrast and the IP responses associated with the oil-water interface within...

.... This paper demonstrates that one can observe significant induced polarization (IP) effects in shale reservoir rocks, which can be used in exploration for unconventional reserves. This study is based on application of the generalized effective-medium theory of induced polarization (GEMTIP) for analysis...

... attenuation in rocks is dominated by a fluid-flow mechanism. The loss mechanism due to multiple scattering is found to be negligible. This implies that extraction of fluid mobility (permeability to viscosity ratio) in reservoir rocks using low frequency (10 to 150 Hz) seismic data should be possible. We...

Our cement quantification method combines soft-sand, stiff-sand and intermediate-stiff-sand models and is a physical based approach to quantify...

... SUMMARY We investigate the ability of complex electrical measurements to monitor the CO 2 front propagation within brine-saturated reservoir rock. A laboratory facility has been developed to perform CO 2 -brine substitution experiments under reservoir conditions. In the present study, CO 2...

... Summary We used a theoretical rock physics forward modelling and synthetic time lapse seismic data to show the possible use of attenuation to monitor hydrocarbon saturation in reservoirs. Given the time variant changes in saturation and the properties of the reservoir rock, the rock physics...

... ABSTRACT For homogeneous fluid-saturated reservoir rock, normally, there is no big difference between seismic reflection coefficients calculated using Gassmann''s theory and Biot''s theory. However, for a heterogeneous reservoir rock, this difference can be as high as 10% (Liu, et al. 2010...

... Summary In the study area, delta front sands and distributary channel sands characterized by rapid lateral variations dominate the reservoir rock. Both extrusive (lava flow) and intrusive igneous rock facies are distributed randomly in the target interval. The resolution of the seismic data...
