Ocena efektywności stosowania wybranych metod wtórnych i trzecich eksploatacji ropy naftowej z wykorzystaniem symulacji komputerowej
(2010) Wojnarowski, Paweł; Pyrzak, Paweł
Effective exploitation of matured oil fields became important problem because of high oil demand. It is possible to increase recovery factor by application adequate secondary or EOR method of exploitation. In this work efficiency analysis of water flooding and polymer flooding for Carpathian oil field was done. Results of multivariant numerical simulations shows, that for selected heterogeneous reservoir polymer flooding is much efficient and could be used directly after primary recovery.

The model of development of the multihorizontal, hydrocarbon reservoir using advanced exploitation methods
(Wydawnictwa AGH, 2018) Dudek, Jacek; Janiga, Damian; Wojnarowski, Paweł
The decreasing number of discoveries of new large hydrocarbon reservoirs as well as the significant technical progress promote the use of enhanced oil recovery methods. One of the most popular is the sequestration of carbon dioxide in matured or depleted hydrocarbon reservoirs. It allows to achieve the synergistic effect of increased crude oil production and underground sequestration of injected gas. In this paper the model of development of the multi horizontal, oil & gas field using multilateral wells technology connected with simultaneously implementation of the EOR-$CO_2$ methods was presented. Based on the performed model, ten-year productions forecasts were made, which results unambiguously confirmed the significant efficiency of the applied technological solutions with indication of the interesting prospects of their implementation in similar reservoirs.

Uwarunkowania techniczne i ekonomiczne sekwestracji CO2 w złożu ropy naftowej
(2011) Wojnarowski, Paweł; Pyrzak, Paweł; Kosowski, Piotr; Stopa, Jerzy
Geological sequestration of CO2 generates costs connected with gas separation and injection, which in some situations makes this process unprofitable. Solution in this situation can be connection of this process with enhanced oil recovery. In majority oil fields only small part of oil is produced witch standard methods of exploitation. Experience from developed projects shows that CO2 injection into partially depleted reservoir can increase oil production making this process cost-effective. In this work technical and economical efficiency analysis of CO2 injection into Carpathian oil field was presented. Numerical simulation of production was developed. Results of multi variant simulations shows, that CO2 sequestration increase oil production, but there is no simply correlation between amount of injected gas and production increment. Capacity of typical Polish Carpathian oil fields is not sufficient for power plant emission. For this kind of process more suitable are large reservoirs, which guarantee stable injection during power plant lifecycle.
