It is obvious that the presence of microfractures in a porous medium increases its permeability. What is unclear is the magnitude of this effect, as it cannot be calculated directly. With the assumption that the fractures are small channels, it is possible to calculate the permeability of a fracture at a given state. In 2018 Pasztor proved that under laboratory conditions the flow will be laminar in the channels, hence the fracture density can be easily determined from simple laboratory measurements (with the ?per...

The perforation channels are the only conduits between the reservoir in production and the producing well, so it is quite obvious that their parameters seriously affect the productivity. Under this highly volatile oil price environment aiming for the best productivity has the highest priority. For this reason, the need for understanding the effect of the perforation parameters on the inflow is urgent. In the previous years, Pasztor has proposed a new concept to calculate the pressure drop caused by the perforation...
