The Financial Post reports in its Friday edition that Ensign Energy Services has kept a presence in Venezuela through years of upheaval and sanctions, unlike rivals who left, even as new U.S. policies allow American oil-field service companies to return. The Post's Meghan Potkins writes that Ensign's chairman is Canadian billionaire Murray Edwards. Ensign has quietly kept rigs running in Venezuela for more than two decades. It recently accounted for the country's entire active rig count, according to Baker Hughes data, with crews currently operating two drilling rigs in the South American country's Orinoco heavy-oil region. Ensign chief operating officer Bob Geddes says: "We're the only Canadian company -- the only oil-field service drilling company -- operating in Venezuela. We've stuck through Venezuela, thick and thin, and here we are with a little bit of blue sky ahead." The Trump administration issued a general license allowing U.S. oil-field service companies to operate in Venezuela, easing previous restrictions that had limited companies like SLB and Halliburton. The move aligns with Washington's plan to boost crude production in Venezuela after the U.S. removed former president Nicolas Maduro on Jan. 3.
