The club was created in 1962 by a group of workers, laying the foundations of the future Petroleum Refinery Neftochim, which had not yet been named.

The stadium in complex Lazur, however, was still frequented by the same enthusiastic crowd of fans that had supported the team during its years in second division.

During those days, the local rival team – FC Chernomorec – tried on numerous occasions to "steal" Neftochimic's stadium.

At the time FC Chernomorec was a member of Bulgaria's elite division, but it played its home games at a place called "Kolodruma" which did not suit the team's ambitions.

Neftochimic finished at 8th place in its first season and reached the semifinals of the Bulgarian Cup eliminating champions Levski Sofia on its way.

In 1997, PFC Neftochimic finished second after a series of referee's mistakes in favor of champions CSKA Sofia and won again the Professional League Cup.

In the 2000–01 season Neftochimic eliminated AC Omonia Cyprus with 2:1 on aggregate, but later was defeated by Lokomotiv Moscow – 0:0 and 2:4.

On the next day – July 7 an amateur football club called "Athletic" was renamed to Neftochimic 1986 and was declared by its new owners as successor of the old team.

Lazur Stadium's capacity of 18,037 seats was quite outnumbered in the past by eventually reaching up to 25,000 in derby games between domestic Naftex and leading teams from the country.
