The effects of process conditions on the char reactivity: The experimental studies and the mathematical modeling
The internal pore structure of chars derived from many bituminous and sub-bituminous coals can be best described by bi-modal pore size distribution. Their macropores, which account for nearly all the porosity, are ...
NMR formulation evaluation: Hydrogen index, wettability and internal field gradients
Nuclear Magnetic Resonance (NMR) well logging is finding wide use in formation evaluation. In most cases, it is adequate to use default parameters and interpretation methods to get formation properties. In this work, we ...
Mechanisms of wettability for crude oil/brine/mica system
The system under investigation is the crude oil/brine/mineral (COBR) system. Deposition of polar asphaltenes from oil causes mineral wetting to alter from strongly water-wet to less water-wet. The degree of alteration ...
