Exploration and production company Dragon Oil says it has received a 'preliminary' approach about a possible takeover offer for the company.
The company, which is listed in Dublin, earlier this year announced that it would move its holding company, the ultimate owner of the group, from Ireland to Bermuda.
Dragon Oil, whose main asset is located in Turkmenistan in Central Asia, is to keep a secondary stock exchange listing in Dublin.
The company said at the time that 96% of its share capital was held outside Ireland and it no longer had any commercial link with the country. It has been headquartered in Dubai since 1999.
