"perforation hole" is a correct and commonly used phrase in written English.
It refers to a hole made by perforating, or puncturing, a material such as paper or metal. Example: "The perforation holes on the sides of the paper made it easy to tear out the page from the notebook."
In fact, there exists a pressure drop along the perforation hole.
Therefore, for the horizontal well studied in this paper, the perforation scheme with denser perforation hole at the toe end and sparser perforation hole at the heel end is a more appropriate choice.
It is found that, the perforation hole diameter and the perforation pattern porosity are the governing parameters of the constituent TF's.
After integrating the point sink solution over the perforation direction, the pressure response of any perforation hole in the formation is obtained.
In this model, the fluid flow at each perforation hole was taken into account, and the perforation tunnels were treated as many infinitesimal sections.
The measured p-wave velocity showed that VP increases along the perforation hole from the beginning of the hole toward the block boundaries.
In addition, we also introduced a criterion when calculating the mixing loss between two perforation holes.
The real producing part for horizontal wells should be quantities of perforation holes.
For horizontal wells with perforation completed in bottom water reservoirs, formation fluids firstly flow into perforation holes before converging in the horizontal wellbore.
Then, a model describing the damage zone must be introduced to characterize the influence of perforation holes (Umnuayponwiwat and Ozkan 2000; Muskat and Wycokoff 2013).
Therefore, the perforation holes can be regarded as "source-sink" term, and this kind of problem can be solved with a source function.
