Qatar Petroleum (QP) has broadened its co-operation with US supermajor ExxonMobil by agreeing a deal to acquire a 30% equity stake in two ExxonMobil affiliates that hold interests in licences in the Vaca Muerta shale play in Argentina’s Neuquen basin.

The pair of companies, ExxonMobil Exploration Argentina and Mobil Argentina, hold rights with other partners for seven blocks under unconventional exploration licences with active drilling plans, as well as exploitation licences with pilot drilling and production, according to QP.
