Core versus cuttings samples for geochemical and petrophysical analysis of unconventional reservoir rocks

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...

Analysis of Drugs in Unconventional Samples.

Forensic scientists have long detected the presence of drugs in biological materials using body fluids such as urine, blood, and/or tissues. In recent years, remarkable advances in sensitive analytical techniques have prompted the analysis of drugs in unconventional biological samples such as hair, nail, saliva, and sweat. These samples are easily collected, although drug levels are often lower...

Petrophysical Evaluation of Unconventional Najmah Formation of Kuwait

Nmr Petrophysical Predictions on Digitized Core Images

NMR is a popular logging technique used to estimate pore size information, formation permeability, wettability and irreducible water saturation. Quantitative interpretation of NMR data is based on a set of fundamental assumptions (e.g., pore isolation and fast diffusion). These assumptions establish the quantitative link between NMR response and petrophysical predictions. While there is a need ...
