Gas field in Neamț County, Romania
The Roman-Secuieni gas field is a natural gas field in Secuieni, Neamț County, Romania lying of Roman and from Bacău. It was discovered in 1992 and developed by Romgaz. It began production in September 1995 and produces natural gas and condensates. The total proven reserves of the Roman-Secueni gas field are around 850 billion cubic feet (24 km3), and production is slated to increase from 60 million cubic feet/day (1.68×105m³) in 2007 to 84 million cubic feet/day (2.4×105m³) in 2010.
The Roman-Secuieni gas field is one of the largest in Romania. With proven reserves of in 2018, it ranked third after the gas fields at Deleni () and Filitelnic (). Roman-Secuieni is also the most important gas field from the Moldavian Platform. The Sarmatian sandstone reservoirs from that region are exclusively gas-bearing (more than 98% methane), the most significant fields being those at Roman-Secuieni, Valea Seacă, Bacău, and Mărgineni. These gas deposits are hosted in combination traps, with a marked lithological character due to frequent vertical and lateral facies variations. At Roman-Secuieni, the gas accumulates in detrital, lens-shaped bodies, grouped into 12 complexes; the deposit is divided into tectonic blocks by sub-vertical faults.
