About 9 km outside Krosno, there is a town of Jedlicze, where a petroleum refinery is located. The plant was built in the early 20th century in the nearby village of Borek (today part of Jedlicze), after the area received access to railway which facilitated transport.

The Petroleum Refinery was established by Hanover-Galician Oil Company in Krosno, affiliated to Hungarian-Galician Petroleum Industry Join-Stock Company in Budapest, and from 1911 associated with Dutch-French Company "Du Nord"; this was the most advantageous arrangement for the refinery.

By 1912 the refinery was thoroughly expanded and modernized. At that time, kerosene, gasoline, the so-called blue oil, paraffin and bitumen were produced there. Owing to the advanced refining technologies used here, the products were exported to Belgium, France, the Netherlands and Germany. In the following years, the owners of the refinery changed a number of times. During World War II, the Germans produced gas and oil in Jedlicze for their military needs. Since 1999 PKN Orlen has been the majority shareholder of Jedlicze Petroleum Refinery.   

At the municipal cemetery in Jedlicze (about 1.5 km from the refinery) there is the grave of Tytus Trzecieski (born on 28 December 1811 in Bażanówka, deceased on 24 December 1878 in Polanka), a landowner and philanthropist, who laid the foundations for the Polish oil industry.
