Impact of Wettability on Reservoir Quality Distribution and Preservation

Reservoir quality can be defined as the measure of the level of porosity and permeability of a rock, reservoirs with good or excellent qualities have porosities and permeabilities between and above the range of 15-20% in porosities and 0.01mD in permeability. These properties of the reservoir and its distribution, is of utmost importance in subsurface energy and resources exploration. Micro-scale mechanisms such as cementation, compaction, grain texture, and sorting, have been proposed to explain the distribution of reservoir quality in the subsurface. The above-mentioned factors mainly describe the rock structure. Additionally, factors that link fluid/fluid/rock interactions such as wettability are found to play a key role in reservoir quality.
