Predicting the total porosity of shale gas reservoirs

open access: yesPetroleum Science and Technology, 2017
ABSTRACTThe favorable zone with organic-rich shale reserve is the “sweet” in the exploration of shale gas, while the logging evaluation of reservoirs, to which the accurate assessment of total porosity is instrumental, is critical to seek this “sweet.” Taking the reservoirs in the Wufeng-Longmaxi Formation in Jiaoshiba region of Fuling, China as an ...

Total porosity of high-pore-volume silicas by liquid adsorption

open access: yesJournal of Colloid and Interface Science, 1980
Abstract This study examines some difficulties in determining the total porosity of silica catalysts by liquid adsorption. In the commonly used liquid titration method, high-pore-volume silicas exhibited a magnified sensitivity to the effects of surface tension and particle size.

Total porosity, theoretical analysis, and prediction of the air permeability of woven fabrics

open access: yesJournal of the Textile Institute, 2012
Air permeability is one of the most important properties of textile materials that ensure their comfort. For many materials for technical applications (filters, sails, vacuum cleaners, parachutes, etc.), this is one of the main properties that determine their quality.

TOTAL POROSITY AND OPEN‐PORE POROSITY IN THE DRYING OF FRUITS

Journal of Food Science, 1980
ABSTRACT A simple procedure has been implemented to measure porosity of apples as a function of moisture contents. The method has been applied to apples with change in moisture contents by conventional air drying. It is shown that the pores, which for biological reasons are open, i.e.

A new method for constraining total porosity: The new total porosity-electrical resistivity upper bound

The Leading Edge, 2006
Electrical resistivity is one of the most commonly collected types of geophysical well log data used in groundwater investigations. Because electrical currents respond to changes in a formation's electrical properties and pore space characteristics, resistivity data are typically used together with gamma ray logs to qualitatively interpret changes in ...

Total voltage effect and electrode porosity

SPIE Proceedings, 1994
`The total voltage effect'--being a main characteristic of vacuum insulation is explained from an earlier offered mechanism of vacuum insulation deterioration point of view. When an external electric field sagging in the negative electrode cracks and pores in their volume ionization processes occur.
