Villa Petrolea was built in 1882-83 for the company personnel. Discernible in the incessant smoke emissions of oil industry enterprises, it resembled the Gulustan villa. Well-known Polish specialist E. Beklin was specifically invited from Warsaw to design the mansion. When it was clear that the local soil was contaminated with oil residue and wastes, ships loaded with fertile soil were quickly dispatched from Lankaran. Water for irrigation was brought in from Astrakhan. A total of 80,000 trees and decorative shrubs were brought from Russia, Georgia and other parts of Europe. The villa, surrounded by fountains and swimming pools, was entirely at the disposal of the Nobel brothers and his servants. Many statues, works of art, sculptures and books were delivered from Petersburg. Local and Iranian carpets adorned the rooms of the mansion to create a truly aristocratic atmosphere. Wasting no time, the Nobel brothers rented the Pirallahi island and discovered a major oil field there in 1904. Over a short period of time the small fishing village developed into an industrial settlement. There was a fire temple and a mosque in the settlement, which is why it was called Pirallahi. People were coming here from cities and villages, eventually branding Pirallahi Nobel’s Sakhalin.
