The oil price crisis has changed the way how we treat our producing wells. Nowadays production intensification is not just a possible option to increase the flow rate of wells with poor performance, but a treatment we must consider for every well to achieve ultimate productivity. However, before the actual treatment a series of different steps are necessary to take, such as candidate selection, method selection, treatment planning and decision making. These steps require the cooperation of different personnel, mos...

Hydraulic fracturing is one of the most widely and commonly applied production intensification method in the petroleum industry. The procedure?s main aim is to increase the contact area between the reservoir rock and the production system resulting in elevated productivity. In order to prevent the complete closure of the induced fractures the application of so-called proppant agents is obligatory. The size, shape, distribution and number of the proppants remained after the closure will affect the tortuosity and av...

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...

In 2016 Pasztor and Schultz[1] proposed an analytical method for calculating a perforation designпїЅs effect on hydrocarbon-well inflow, using a new concept to analyze the effect of the shape of the perforation channelsпїЅ drainage area. The method compares well with standard industrial methods used to calculate the pressure drop caused by a given perforation design. In 2017 Toth and Pasztor[2] applied their model to investigate geothermal-well inflow, and achieved promising results. The modelпїЅs complexity makes...
