CSO Boldești-Scăeni

The club was founded in 1947 as Petrolistul Boldești and played for twenty-six seasons in the third Romanian football league.

In the 1967–68 season, occupying the 3rd place in East Series of the Ploiești Regional Championship with 29 points (13 wins, 3 draws, 6 losses and 34–25 goals), Petrolistul promoted to Divizia C.[1][2] Between 1979 and 1994, the club has evolved into the county championship two times, 1988 and 1990, being close to promotion, finally taking the second place.

1993–94 Divizia C – Prahova County season was dominated by the Petrolistul, who held the first position without "knowing" the defeat (record of the competition) with the following ranking: 30 22 8 0 71–18 52 points.

[3] In the summer of 2010, at the initiative of the mayor of Boldești-Scăeni, Constantin Bucuroiu, and the leader of the Boldești Scaffold syndicate, Mihai Nicolescu, „Boldeștina” reappeared in the landscape of the Prahova County football, evolving in the North Series of the Liga V – Prahova County, the fifth tier of the Romanian football league system, which they won without a defeat, promoting to Liga IV – Prahova County.

[5] They held on there for two seasons, before relegating back to the county league, even though they had the opportunity to remain, due to some of the promoted teams being unlicensed.
