"It is easy to measure the water in the pore space
and capillary pressure.
Bulk density, particle density, organic matter and pore space
Through theoretical analysis, it is concluded that the pore pressure decreasing can lead to the effective stress of the rock increasing, resulting in the compression of the pore space
and the decrease of pore space
, which eventually leads to permeability decreasing .
Firstly, during pyrolysis, organic matter in oil shale undergoes a phase transition from solid to liquid and then to gas, forming a considerable expansion stress in its pore space
. This phenomenon causes rock damage and failure.
In this study, with the increase of adhesion time, the cells, initially adhered to the fibers (Figure 4A), stretched through the fibers and the pore space
to adhere to other cells and fibers (Figure 4C).
Total porosity is defined as the ratio of the entire pore space
in a rock to its bulk volume (Nnaemeka 2010), or the porosity derived directly from the logs without correction for the clay content.
During the dry season, the water evaporated and the iron oxide remained in the soil pore space
and cemented the tunnel walls.
By spraying bacteria and cementation solutions onto the surface of sands, calcium carbonate (CaC[O.sub.3]) is generated and rapidly precipitated into the pore space
among sand particles.
 modified the LW equation by introducing the correction factors of the pore shape and tortuosity to describe the pore space
of natural rocks.
 studied the pore space
morphology in two early mature samples of Posidonia shale using BIB-SEM.
Under the sea just off those states' coasts, "sediments were tightly packed together without much water in the pore space
between the sediment grains - an arrangement that can make the plates more prone to sticking to each other and building up high stress that can be released as a large earthquake," the university explained.
The oil in the well begins to cross its cloud point threshold, and paraffin crystals start to precipitate as the oil moves from the pore space
to the wellbore opening.
