The Kstovo Refinery, also known as Lukoil-Nizhegorodnefteorgsintez (Russian: Лукойл-Нижегороднефтеоргсинтез) is a oil refinery plant in the Russian city of Kstovo, one of the largest in the country. This refinery has belonged to the Russian company Lukoil since 2001.
In October 1950, the Soviet Council of Ministers approved a resolution for constructing an oil refinery near the city of Nizhny Novgorod.[1] The local councils then collected surrounding farmlands and began construction.[2]
On August 23, 1958, a celebration was held at the plant for the completion of construction, and the plant began sending off finished products.
In the 1990s, following the dissolution of the Soviet Union, a private company was created to regulate the plant, called "Nizhegorodnefteorgsintez" (Russian: Нижегороднефтеоргсинтез). The production output in 1997 was at 12.3 million tons, and exported as far west as Hungary and east as Tatarstan.[3]
In 2001, the company became part of the large coporation Lukoil, and owned over 80% of its shares by 2006.[4]
In 2010, Lukoil made an investment worth $975 million to create a new complex at the plant, which was expected to increase production from 1.8 to 3.2 million tons per year.[5]
In 2022, the company made an investment worth 100 billion rubles to create a new complex for processing oil residue, which is expected to improve production.[6]
