The Mamu gas field is a natural gas field in Mamu village, Mădulari commune, Vâlcea County, Romania. Discovered in 1980, it was developed by Petrom, beginning production of natural gas and condensates at the Mamu 4337 gas deposit in 1988.[1] [2]
From 1992 to 2004, Shell invested over US$230 million into oil and natural gas production in Romania, which led to the opening of a gas condensate field at Mamu. The Mamu 4320 gas deposit was discovered in 2007.[3] In 2009 the total proven reserves of the Mamu gas field were around 276 billion feet3 (7.8 km3), with production expected to increase from 24 million ft3/day (0.68×105m3) in 2007 to a maximum rate of 84 million ft3/day (2.4×105 m3).[4]
In 2011, the Mamu 4335 and 4338 wells were drilled at a depth of around as part of the Mamu gas field redevelopment program, which includes the drilling of new wells and the modernization of surface production facilities. As a result, the production on the field increased by about .[2]
In 2018, the Mamu 4317 well was drilled by Petrom in the vicinity of the Mamu gas field, at a depth of about and confirmed the existence of gas and condensate. Due to the proximity to the existing infrastructure, the well went into production at the end of October 2018, with an initial volume of over .[5] [6]
As of 2018, the Manu gas field had a production of, enough to heat approximately 180,000 homes.[5] [6]
