On 22 November 2018 OMV Petrom reported having successfully completed appraisal well Mamu 4317 at the Mamu field in the Mamu permit with gas and condensate. Mamu 4317 was spudded in early May 2018 using Daforaâs âBentec 350 ACâ rig and had a planned total depth of 4,331 m. The wellâs initial production reached some 1,100 boe/d. The field is located in the southern part of the country about 40 km northeast of the city of Craiova.  The last known activity in the field dates back to the 2009 â 2010 period when OMV Petrom drilled two successful sidetracked wells: Mamu 4335ST and Mamu 4338ST. Both wells were drilled as part of the field re-development program and contributed to increase the production of the field by around 2,800 boe/d. The Mamu field was discovered by the Ministry of Petroleum in 1985. Its reservoir is situated below a depth of 4,000 m in the Triassic to Dogger sandstones. Production at the field started in 1988.  Interest in the 29 sq km Mamu licence is held solely by OMV Petrom SA.
