Experimental Study of Induced Polarization Effect in Unconventional Reservoir Rocks

Unconventional hydrocarbon reserves substantially surpass those of conventional resources and therefore are extremely economically attractive. However, exploration and production of unconventional reserves is challenging. This paper demonstrates that one can observe significant induced polarization effects in shale reservoir rocks, which can be used in exploration for unconventional reserves. T...

Magnetically induced circular polarization.

Self-induced polarization anisoplanatism

This paper suggests that the astronomical science data recorded with low F# telescopes for applications requiring a known point spread function shape and those applications requiring instrument polarization calibration may be compromised unless the effects of vector wave propagation are properly modeled and compensated. Exoplanet coronagraphy requires “matched filter” masks and explicit designs...

Microwave Induced Nuclear Polarization

The classical method to increase the nuclear spin polarization is the "solid effect" mainly developed by Abragam and Jeffries, where the Boltzmann polarization of unpaired electrons present in the sample is transferred to the nuclei by inducing forbidden transitions which flip one nucleus and one electron simultaneously (1,2). A different method is the optical nuclear polarization (ONP) which w...

Probing field-induced tissue polarization using transillumination fluorescent imaging.

Despite major successes of biophysical theories in predicting the effects of electrical shocks within the heart, recent optical mapping studies have revealed two major discrepancies between theory and experiment: 1), the presence of negative bulk polarization recorded during strong shocks; and 2), the unexpectedly small surface polarization under shock electrodes. There is little consensus as t...
