North Drilling Company (, Hefari-ye Shimal) is an Iranian company specialized in drilling oil and gas wells and its services in all regions of Iran and world, to global customers. The company was privatized in June 2009. As of February 2010, Mehr Eghtesad, a quasi-government investment company, owned 20% of its shares on the Tehran Stock Exchange.[4]
The company owned nine land rigs and three jackup rigs during these years[5] and is managing drilling operation in Persian Gulf, Caspian sea,[5] and Kuzestan, Ilam, Khorasan, Bushehr and Fars provinces of Iran.
In 2009, SADRA launched a domestically built semi-floatable drilling rig for the Caspian Sea owned by NIOC (National Iranian Oil Company). The semi-submersible platform is able to operate at water depths up to 1,030 m and can drill down to 6,000 m under the seabed.[6]
